Win the Ding 1617

() Let's do what we say, we have collected more than 3000, add a new chapter, the character explodes, long live the motherland!

After sending away the guests from all over the place, checking out all kinds of gift money and gifts that he got for his daughter's full moon, he couldn't help but startle the guard.

Officials at all levels within one's own system are not counted, because the Shou Han has a word first, and those who give gifts that exceed their salary will go to Bao Zhongchen to drink.Therefore, most of the gifts of these people can be summed up in light of courtesy and affection.Of course, a guy like Zhang Xiaohu can be an exception, he can plausibly say that it is my previous savings.

The bulk of the gifts were sent by various surrounding forces.These guys, when they make a move, they are gems and pearls that are calculated by liters and buckets.This really made Li Shouhan feel ashamed, lamenting loudly that he is a bumpkin.

However, if there is nothing to show courtesy, it is naturally stealing or stealing.

Oh, it's not appropriate to use this word here, it is natural that people must ask for something when they are courteous.

The goals of these people are as if they have been discussed.

"Buy arms!"

"Buy knives and guns!"

"Buy a cannon!"

"Buy armor!"

"Buy cotton!"

"Buy china!"

"Buy satin!"

"Buy everything produced in Nanzhong, and the general allows us to buy it!"

Therefore, the shopkeepers of the Han Yuan Company happily inspected the piles of contract documents piled up in front of them, and looked at the gold piled up as high as a mountain in the warehouse.

That's right!It is gold. In view of the huge regional disparity in the exchange rate between gold and silver, Shou Han only accepts gold in foreign trade, mainly in export trade.Of course, if you receive silver, you must consider the exchange rate gap.

"The statistics are out." Lin Huofeng, the big shopkeeper of the Hanyuan Company, held the account book with a somewhat reserved hand, and reported in front of Shouhan.

"A total of 14 pieces of dyed cotton cloth were ordered from various places. Among them, [-] pieces were paid for in full, [-] pieces were paid for with raw materials, mainly cotton, and the rest All of them paid a [-]% deposit according to the rules."

"Purchases such as porcelain, silk, raw silk, etc., the quantity and variety are rather messy. Allow me to report later. The goods with the largest amount and quantity are the military orders that the Lord said. All the goods were paid in one lump sum. For..." Lin Huofeng lowered his voice and revealed a shocking number to everyone present.

Going back a few years, this number may cause many people to have a sudden cerebral hemorrhage, but now, people's psychological endurance is much stronger.Even so, some people just click their tongues.

Zhang Xiaoqi, Zhang Xiaohu's third brother, is one of them.

"These guys, what do you need all these spears and guns for?"

"Boss Zhang, you don't know about this. According to adults, this is called an arms race. Your nearby enemy or a bad neighbor has a good knife or a long gun in your hand. What would you do with only a hatchet?"

"Bird! I must have two knives, or one knife and one gun to sleep well!"

"That's good, but you have a knife and a gun, what about the people who have enemies with you? Shouldn't you have a firecracker?"

"That's right! That's how it should be!"

"Hehe, the third shopkeeper, your idea is exactly what this generation thinks. In the end, we received the contract for more than [-] artillery pieces! More than [-] sets of armor, [-] handles of extinct knives, and [-] guns. Ten thousand! There are still some people who are negotiating with us and want to buy some firecrackers from He Jing, but my lord is still hesitating here. If the firecrackers are included, then another ten thousand will be added.”

"Ask us, or implore us, to hand over these knives, guns, artillery, etc. to them within three months, even if they are notified, their ships will naturally come and take them away."

"Old Lin," the guard sitting on the tiger-skin chair behind the handsome case, was speechless for a while, "These cannons have been ordered for more than 200 pieces? What kind of cannons are they? Don't sell your sharp weapons to others, ri Finally, these cannonballs fell on us!"

"My lord, we have opened eighty small Franglers, 55 large Franglers, forty three-pound guns, and 47 six-pound guns, totaling 220 and two."

"Made! The numbers are quite auspicious, they come in pairs!" Shou Han cursed, picked up a list on the table and looked at it.

According to the technical level and cost of artillery manufacturing in this era, Shouhan made a very conscientious quotation for the sales of his artillery to outsiders. Taking Frangji as an example, a gun with a body weight of about 200 catties Dafo Lang machine, excluding the weight of the gun and the gun mount, is sold for [-] taels of silver.Five blunderbusses and twenty cannons are presented as gifts.And send gunsmiths to provide after-sales service, including teaching and assembly.

Later, it was found that such a pricing method was disadvantageous for no other reason, all because the ductility, toughness, and tensile properties of ductile iron are much stronger than traditional bronze and iron cannons, and their own weight is much lower.

This order list includes the Dutch, Ri himself, the Zheng family and the Mo family in the north, the Burmese King Toungoo and the Arakan king in the west, and the Siamese who have signed a treaty with Nanzhong and pretend to be vassals .

Almost all the political and military forces in the surrounding area are included. As for the small chieftains, they are required to buy some swords, guns and armor. If there are firecrackers for sale, then thank the Bodhisattva.

"Since we have received money from others, we have to give them something." After thinking for a while, Shou Han made such a decision.

"Tomorrow, come with me to the workshop."

"This powerful regime, from its embryonic period until recently, has created false appearances in technology to deceive the world. In terms of the most common metal manufacturing process, or military equipment manufacturing technology, for a long time, we have It is believed that he relied on huge manpower to complete it, just as many people pointed out in their works, the so-called sea tactics. However, I carefully studied the population situation and food consumption in Li's ruling area at that time , I was surprised to come to a conclusion, Li Shouhan, it is impossible to devote the huge manpower we imagined to casting artillery, smelting metal and other activities."

Vladimir Ilyich Ulyanov stripped off Li Shouhan's mask in his masterpiece "Eastern Empire-Technology".

Shou Han took the black goggles handed over by Ling Zheng, and carefully watched the molten iron being poured into the mould.Nowadays, goggles have become a popular item among generals at all levels of the navy and land division.The first one was Zhang Xiaohu, a tired guy, who found that it was very effective in preventing the glare of the sun, so he begged half-begged from the guard, and asked for twenty pairs. Distributed to the ships under his command as paramilitary equipment for the captain and gun sail captain.Seeing that the left wing of the Navy had it, Zuo Tianpeng, who was on the right wing, was not to be outdone, and asked for twenty pairs.Immediately afterwards, Gonzalez from the training fleet of the Martial Arts Hall, the Guards Battalion, the Xuanwu Battalion, the Phoenix Battalion, and the Qilin Battalion stretched out their hands to ask for it.

Helpless, the guards had to be exposed to both rain and dew, one for each battalion officer, one for each artillery team officer, and one for each rangefinder.As the same equipment as the clairvoyance, it is registered and recorded.

Today, the main firearms of the South China Army consist of rockets, twelve-pound cannons, eight-pound cannons, large Frang machine, small Flang machine, and firecrackers. They are simple, cheap, and effective.

The material used is the most deceptive nine-turn steel - ductile iron.Friends who are interested can check it out. The excellent casting performance, heat resistance, corrosion resistance, wear resistance, vibration reduction, cutting performance, economical performance, ductility and toughness of ductile iron are far away. Bronze is the best material for making guns in this era.

"My lord, now we have made some adjustments to the original cannon-making process!" In the gun station, there were people coming and going, the sound of metal crashing, and the neighing of mules and horses transporting various supplies, so Ling Zheng had to shout loudly. Shout to the guard.

In order to meet the requirements for artillery everywhere, the technicians of the Gunnery Institute reformed the cylinder forging method originally suitable for bronze cannons into the iron mold water cooling method.That is to combine the iron mold casting technology proposed by Gong Zhenlin with the Rodman method, and improve it according to the characteristics of its own material and ductile iron.After small-scale trials, the artisan association approved the process.

Today is the day to officially start casting cannons.

After being tempered at a high temperature of [-] to [-] degrees by the blast furnace, the ductile iron becomes liquid, and the liquid ductile iron is poured into a hollow iron mold with a water injection pipe. Workers began to slowly add water to the water injection pipe in the iron mold.The water flow slowly enters the cooling pipe in the iron mold from the water inlet set at the tail of the gun, and flows slowly through the mold along the line designed by people, cooling down the enthusiasm of the melt with your own calmness, and quickly , The cold water turned into warm water, the warm water turned into boiling water, and the boiling water flowed out from the outlet of the gun tail with steam, completing its own task.

"The climate in Nanzhong is hot, and it is obviously impossible to cast cannons with mud molds that are popular in the mainland. The mold forging method proposed by the master back then is certainly superior, but it has high requirements for processing tools and staff skills. The method proposed by the master can be scaled up." Production, the production cycle is short, and the requirements for low cost are inconsistent." Ling Zheng defended those guys who were "daring" and "unauthorizedly" changing the technological process formulated by the lord.

However, Shou Han's attention was not on these words, he just hummed a little casually, but his eyes were fixed on the young people in the workshop wearing yellow waistcoats.

"Those people followed the vocational education proposed by the lord. After graduating from the school, after receiving education in various schools, they went to the factory for internship. We discussed that every team of 50 people, each team only learns one part of the craft. Craftsmanship, don't mess around with each other." As the master of the workshop, Ling Zheng followed Shou Han's gaze, and immediately introduced the origins of this group of people to Shou Han.

"The important weapon of the country should not be shown to others easily. The smelting of the nine-turn steel and the manufacture of artillery are the foundation for our Nanzhong Army to survive in this troubled world. Don't lose it!"

The ten molds were quickly filled with molten liquid, and the water injectors in charge of cooling began to speed up their movements.

"My lord, it seems that this method of mold casting can be generalized. Farm tools and weapons can all be made with this method. It saves labor and time, and one job saves hundreds of jobs, and one gun saves dozens of times the cost." .And the spin-casting spin out, no time delay, flawless, natural and smooth, twice the result with half the effort, unlimited use."

Hearing Ling Zheng's self-boasting words, Shou Han couldn't help but feel mixed emotions: He thought it would be most suitable to use bronze forged cannons, but he didn't want to turn into cast cannons because of the advent of ductile iron. , It is still cast by the iron mold water cooling method that is admired by countless people.Is it true that as everyone said, one step ahead is a genius, and two steps ahead is a lunatic?

Through the goggles, people could clearly see that the red cannon barrel began to dim. "Continue to cool!" A foreman yelled loudly, and a dozen workers responsible for injecting water into the barrel mold responded in unison: "Inject water!"

Dozens of native laborers carried poles and two huge wooden barrels to supply water for the water injectors.

"My lord, it will take some time to cool down. Why don't we go and look at other things?" Feng Mofeng, who was in charge of the arsenal and gun station, asked in a low voice in Shou Han's ear.

"What are you going to see?"

"The spring you mentioned, my sons and daughters came up with it."

The spring production site is not as heavily guarded as the gun station. In an open space in the Taipingdong Armory, people are busy in full swing according to their tasks.

Thick and thick porcelain rods were placed in the open space, and people picked up the red nine-turn steel rods that were fired at the furnace temperature with large tongs and carefully wound them on the coarse porcelain rods.

The usually tough and strong nine-turn steel, under the action of high temperature, hum!It is also a hundred refined steel that turns into soft fingers.Under the action of workers and pliers, obediently was evenly wound on the thick porcelain rod in circles. The distance between each circle is equal, and it is really beautiful when viewed from a distance.After cooling down, the fixed nine-turn steel bar is removed from the porcelain rod, and it is determined whether it is a qualified spring according to the manufacturing level of the steel bar.

According to the size of the mold during processing, from huge rods to thumb-sized porcelain bars, springs of all sizes are placed before people's eyes.

To be honest, people can guess the general direction and use of other things that have been guided by Shou Han in the past few years. However, what can this thing called spring be used for? Know.

"What is it for?" Shou Han weighed the springs of different sizes with satisfaction, "You will find out after a while."

"Huang Lei Ting!" Shou Han shouted loudly to the representative of the Artillery Division.

"The mark is here!"

"Go and ask Mr. Feng if the gun carriage that your gunner asked him to process is ready."

"Returning to my lord, the gun mounts have already been made. There are two sets of various artillery pieces, all of which are stored in the warehouse." Feng Mofeng, who is used to being silent, answered Shou Han's words in the crowd.

Soon, in the shooting range of the gun test, the twelve-pound guns to the six-pound guns were arranged in two groups, and the randomly selected gunners stood nervously and excitedly according to their respective positions.

Not far behind them was a group of people headed by Li Shouhan.

"The cannons are all the same gun, the difference lies in the mounts. One set of mounts, here, is the set under the yellow flag, with your newly made springs installed, while the other set has no springs installed. The same gun position, the gunner's technical level is also similar, after a while you will know that this spring will come in handy!"

The cannons boomed.

The shells were pushed out of the barrel by the gunpowder, and flew towards the distant mound with full of anger.

The gunners can show off their gunnery skills in front of the lord today, and they all have a 12-point concentration, and they operate many links such as clearing the chamber, charging, loading, aiming, and firing like flowing water.

However, at the moment the cannon was ejected, the craftsmen discovered some subtle differences:

The two thick springs installed at the side and rear of the gun barrel and closely connected with the gun mount were compressed tightly by the rapidly moving backward barrel, but they also absorbed a lot of the castration of the gun barrel. With the final movement, the spring bounced off, pushing the barrel forward.Several gunners took advantage of the opportunity to push the cannon forward, quickly reset it, cleared the chamber, loaded the ammunition package, loaded the bomb, aimed, and fired.After that, reset again.And so on and on.

There is no spring-loaded artillery team on the other side. Although the gunners are also operating with full confidence, after a few rounds of shells are shot out of the chamber, the gunners' physical strength is huge, and the time interval for resetting the artillery is getting longer and longer. Slower and slower.Finally, a gunner fell by the gun mount like a puddle of mud.

It was so!

The craftsmen understood a little.

Those two springs, and the connecting rod installed together with the spring, constitute the most primitive recoil machine, the spring is the recoil spring, and the connecting rod acts as the recoil rod.Although the process is rough, the principle is the same.

When the gun recoils, the recoil rod, whose tail end is connected to the gun body, is pulled back.At this time, the recoil head compresses the recoil spring.When the recoil ends, the recoil spring stretches, pushing the recoil rod forward, and the recoil rod drives the barrel back to the original firing position.There are many different types of recoilers, some use recoil springs, some use compressed air, and some use both.However, no matter what type of recoil machine, its working principle is to use recoil energy to compress the spring.Compress the gas or compress the spring and gas, then use the stored energy to return the barrel to its original firing position.

"My lord! This is a good thing!" Huang Lei was as excited as if drunk, his face flushed. "In the past, every time the sons fired more than a dozen cannons, they were exhausted. I marked it just now. The Yellow Flag Artillery Team fired thirteen shots. The gunners are still full of energy, and the artillery resets quickly. In this way By comparison, with this, this spring cannon, a group of gunners can defeat the same two groups of cannons!"

"Master Huang, you don't know something!" Ling Zheng who was next to him didn't know when he was standing next to the guard with a flintlock gun.Zhengyu handed the firecracker in his hand to the guard to watch.

"This thing is still useful!"

Ling Zheng pointed to the position of the dragon head and explained to Shou Han in a low voice. Huang Leiting hurried over to watch.Although flintlock guns are easier to operate than matchlock guns, and musketeers don't need to check the matchlocks or carry a bundle of ropes with them, but the misfire rate of this thing is really high. If the character is good, it is around [-]% , those with bad character almost reached [-]%!

That's not to mention, every time you pull the trigger, you can't wait to concentrate all your strength on the index finger, otherwise, you won't be able to create sparks!

"We made the spring small and tight, and installed it at the position of the faucet. You only need to pull the trigger lightly, and under the action of the spring, the hammer can hit the flint hard, which not only increases the probability of ignition, but also reduces it. The power of pulling the trigger, the dolls have calculated that for every ten trigger pulls, the average firing rate is around eight times!"

"Eight times?" Hearing this, Huang Lei couldn't help but click his tongue secretly. Does this mean that the rate of blindness is about [-]%?

"But after all, the consumption of flint is much higher! Alas! Everything has advantages and disadvantages, and sugarcane is not as sweet as both ends!" Ling Zheng smacked his lips, expressing regret.

"It doesn't matter!" Shou Han waved his hand generously, um, this feels good, and he looks like a leader. "What is a piece of flint worth? How many more enemies can you kill, and how much less casualties and wounds you can save? Your merits are immeasurable!"

Hearing these words, the people around were slandering in their hearts: others accumulate merit by burning incense and prostrating their heads, eating vegetarian food and praying to Buddha, buying birds, fish and shrimps and releasing them.

"The enemy killed a lot, and our army suffered few casualties. Isn't that considered a merit?"

Ok?

What the lord said sounds quite reasonable, and the lord is the one chosen by the emperor of heaven, if he said it was right, then he was right!

"Also, this spring has other folk uses. I won't talk about it today. I'll send someone to send me the drawings later. You can make me some pieces of furniture accordingly."

Shou Han has already made up his mind to set up sofas and chairs in the rooms of Yanmeier, Xiuxiu and Meishan, and it is best to replace the beds with springs!In addition, it seems that springs can also be installed on the car as a shock absorber, so, hehehe!

There are always people who come to interrupt Shou Han when he is thinking about it for his own selfish desires.

There is one right now.

"My lord, my lord?" Ling Zheng's son Ling Li rushed over from the gun station.

The ten molds have cooled down, and several craftsmen are using calipers to test the caliber of the artillery.

"The caliber is the same!" The same eight-pound shell was used to test the muzzle, and the distance between the shell and the muzzle was basically the same. Only then did several craftsmen sign their names on the list and press the instructions mold.From the beginning of the casting of these cannons, the craftsmen and technicians in each link will sign the relevant inventory and leave fingerprint buckets. Once there are quality problems in use in the future, the military room will track them down step by step. Until that person lets go.After that comes the dreaded accountability phase.

"No. 25 gun. The caliber model is a twelve-pound gun, the material is nine-turn steel, and the manufacturing process is cast. The play between the shell and the muzzle is [-]/[-] of the inner diameter, which is within the allowable range!"

A technician carefully measured the inner diameter of a cannon, carefully measured the gap between the shell and the inner diameter of the muzzle with a caliper in his hand, and nodded in satisfaction.In the common casting artillery technology of this era, the gap between the inner diameter of the muzzle and the shell is basically about one-tenth, and Nanzhong has reached one-twentieth, in terms of precision alone.It has surpassed almost all countries with artillery manufacturing technology in this era.

However, there are more stringent links behind.

After testing the caliber, it is time to enter the next step, using a boring machine to bore the inner wall of the gun bore to ensure the smoothness of the inner wall of the gun.

Outside the factory of the Gunnery Institute, a diversion channel was built to divert the distant river water into several huge reservoirs.These cisterns are not used to ensure the life of personnel, but for other purposes.

In addition to ensuring the production water of the factory, another purpose of them is to provide power for the factory.

A few copper whistles sounded, and two flags were waved.

The worker on duty on the cistern slowly turned the winch to lift the gate of the cistern, and the water stored in the pool rushed forward along a narrow channel.

A waterwheel is placed at the entrance of the channel, and the blades of the waterwheel are just below the channel of the water outlet. The turbulent water quickly pushes the blades up, and the waterwheel slowly rotates.A long pole connected to the waterwheel rotates slowly and firmly as the waterwheel turns.

Long rods provide raw and reliable power to a horizontal boring machine installed indoors.

On the boring machine, iron steel (steel made of high manganese ore sent by the Mo family) is used to remove the impurities in the ore by calcining the pyrolusite, and to obtain manganese dioxide ore containing about 70% manganese. After many times of crucible In the steelmaking test, a process formula containing 10%-13% manganese was obtained, and a relatively satisfactory high manganese steel was obtained. The first batch of high manganese steel with extremely high hardness became tool steel without exception, and was forged into various Type knives and blades. After mass production, the technological process is determined as first calcining pyrolusite to remove impurities in the ore to obtain relatively pure manganese dioxide. Then manganese dioxide is mixed with iron ore for coke steelmaking, iron Oxygen in ore and manganese dioxide will be reduced under the passionate combustion of coke, and then the crystallization of love—high manganese steel will come out. In order to continue Shouhan's consistent cheating style, high manganese steel is no exception It was given a deceitful trade name, iron steel. It is said to come from an ancient beast. This thing is shaped like a buffalo, but has huge horns, black fur, and feeds on iron. The excrement is as sharp as steel and can be used as a Weapons.) The finished knives began to rotate at a constant speed, and ran straight to the gun barrel fixed on the wooden frame opposite.

After bursts of teeth-piercing metal cutting sounds, someone gestured to indicate that the processing of the gun bore was completed.The workers guarding the waterwheel hurriedly pulled the ram to stop the waterwheel slowly, and at the same time sent a signal to the workers on the sluice to lower the ram on the canal to stop the power of the water flow to the waterwheel.

Several apprentices pulled the iron chain on the pulley block. After a clattering sound, the cannon was hoisted high, and some metal debris floated out from the muzzle, ignition port, etc.Some people used thin brooms and brushes to clean and oil the inside of the gun bore.

Soon, another group of technicians in charge of testing came with their own equipment.

Two people cut a circular steel plate slightly smaller than the caliber of the artillery, took it out of the tool bag, and passed a thin metal rod through the round hole in the center of the steel plate. Two small holes at one end of the metal rod The claw and the steel plate made a light sound, "click".

A slightly fatter technician lifted up this simple inspection tool and stretched it straight into the gun bore along the muzzle. The feeling from the contact between the steel plate and the inner wall was slightly stiff, but the steel plate stretched all the way to the bottom of the gun bore. .

Another technician placed a burning incense stick down the fuse. "Can you see it?" he asked his colleague.

The fat technician opened his eyes and looked into the barrel. In the observation holes reserved on both sides of the steel plate, he found no burning incense head, "I can't see it!"

This detection method uses the principle of straight-line propagation of light. If people at the muzzle can see the bright spots of incense, it means that there is a deviation between the position of the ignition port and the barrel. Either the position of the ignition port is wrong, or the opening is too large.

After taking out the steel plate that served as the simulated drug bag, the technician took out another heavyweight inspection tool,

A twelve-pound cannonball is different from the official cannonball in that there is a depression on the cannonball, and a thin beam is above the depression, and a thin rope made of raw silk follows the cannonball into the chamber. Extend slowly. <Casted in March, processed on a boring machine on the [-]th, tested by technicians Kuang Xiaoshan and Li Mingxi, the muzzle is straight, the bore is straight, the position of the ignition port is appropriate, the shell enters the chamber smoothly, and the inner wall is smooth. "

Li Shouhan, who watched the whole process from the sidelines for a long time, nodded slowly, expressing his satisfaction with the inspection rules and technology of the gun institute.

"Anything else to check?"

"Returning to my lord, before the official storage, we need to conduct an experiment. Because we have not been able to measure the chamber pressure you mentioned, so we have to use the most stupid method." Ling Li, who has grown into the main force of the gunsmith, is methodical. He recounted his actions to Shou Han.

"After the cast cannon has gone through various testing procedures, it is moved to the cannon test field. This cannon test field is not a test cannon test field for cannon fire and shooting, but a remote and open place chosen. The gun barrel is filled with gunpowder. Instead of gunpowder that weighs one-third of the weight of the bomb used in the army, use a long heart to light the match, and everyone should avoid hiding places as far as possible. No harm."

Cannons that have passed such destructive tests can be formally entered into the formation sequence as equipment if they are qualified.If it is unqualified, it will either be re-cast, or it will be marked on an inconspicuous position of the artillery and handed over to the Hanyuan firm for processing. (Cough! Cough cough! I slipped my hand and made a typo. This is definitely not true!)
