Great Tang’s Talented Little Landlord

Li Wangyou rubbed his temples in pain, sipping his tea listlessly.

“Liben, are you here? But something is going on?”

Yan Liben said with a smile: “Master, I should have learned about it yesterday by Tongbing, but the discipline Seeing that yesterday was the day when the teacher entered the house, its inconvenient to interrupt, so I came to report to the teacher early this morning. Teacher, guess what?”

Li Wangyou looked at him and suddenly stood up: “But The hydraulic forging machine is ready?”

“haha, the teacher really got it right. The hydraulic forging machine was completed three days ago, and the recipe has been run by the craftsmen for two days, and everything is normal. Celebrate my teacher. Yan Liben was even proud that he was able to preside over the construction of such a magical machine. For him, it was more happy than winning the lottery.

“Let’s go, take a look.” Li Wangyou also came to the spirit.

Li Wangyou didn’t call the dudes either. After all, this matter still needs to be kept secret before Li Er’s approval.

Not far from Huangyu Cuiwei Palace, beside a river named Qihe, a row of workshops have been erected.

The Qi River is not wide, but the current is very fast.

More than a dozen large waterwheels with a diameter of four five meters have been erected next to the Workshop, and they are continuously and rapidly rotating under the impetus of the endless river.

“Master, you see, here is the Blast Furnace that re-melts private money.” Yan Liben introduced Li Wangyou to various facilities in the Workshop.

For these iron and steel smelting, Li Wangyou knows the nine faculties and knows nothing. It can only be what Yan Liben said and what he listened to.

Li Wangyou also knows that by the time Great Tang, steel melting and forging technology was already very advanced. Not only the steel frying method, but also the quenching and annealing technology, as well as various very advanced steel forging technologies.

Tang Dao can no stronghold one cannot overcome, which is also one of the reasons why Tang Army is invincible.

Only the steel-making Blast Furnace still uses charcoal as fuel, but Li Wangyou remembers it in the heart. He vaguely remembered that it seemed that it was only in the late Southern Song Dynasty that coke was used as a fuel for steelmaking.

Coke is used to make steel, the furnace temperature is higher, and the quality of molten steel produced is better.

However, coke must be made by secondary processing of coal. In this regard, Li Wangyou only knows a general idea, so he is not at all anxious to raise this matter to Yan Liben.

The piles of private money were thrown into the Blast Furnace and slowly remelted into a furnace of copper water under the continuous heating of the charcoal fire.

The craftsmen pour copper water into the mold and wait for it to cool.

“This is to cast copper water into copper bars with the thickness of a copper coin. After the copper bars are cooled, they can be sent out to the hydraulic casting machine and stamped into Copper Coin.”

Yan Liben was very proud to invite Li Wangyou to a huge forging hammer: “Master, this is a hydraulic forging machine manufactured according to your drawings. It is very good. You look at the hammer head, which weighs two. The ten stones are made of pure steel and are extremely powerful. Driven by the waterwheel, they can be beaten twice a minute, day and night.”

Li Wangyou converted it in his mind, and 20 shi It’s 2000 Jin, a one-ton hammer, it’s really amazing in Great Tang.

The one minute Yan Liben said is not the one minute of later generations.

Great Tang inherited Sui Dynasty’s “Daye Calendar”, and used a tool called omission for precise timing.

It is a tool for timing by dripping water. A day is divided into twelve hours, and each hour is five hundred minutes, and one minute is equivalent to fourteen seconds.

In other words, this one-ton hydraulic forging machine can be beaten eight times in one minute, which is very good.

Li Wangyou asked curiously: “Liben, how do you solve the problem of hammer swing?”

The biggest problem with this primordial hydraulic forging machine is the accuracy of beating. Poor, it is difficult to perform fine processing like later forging machines. After all, every time the hammer is raised and lowered, it will swing from side to side to a certain extent, which is quite normal.

However, in order to stamp and forge copper coins, the hammer must be precisely placed on the same point every time.

Because Li Wangyou didn’t know how to solve this problem, he simply acted as a shopkeeper and threw it all to Yan Liben to ponder.

Yan Liben was very proud, and pointed to the thick lever connected to the hammer.

“Master, I made a device here to connect the lever, and let it slide into this funnel-shaped hole when it falls, so as to ensure that the hammer is in the same position every time it falls.”

Li Wangyou thought about it for a long time, and then he probably understood the design of Yan Liben, and couldn’t help but raised his thumb at Yan Liben.

Awesome, really amazing.

Who said that the ancients were not smart, this kind of device, let Li Wangyou do it by himself, is definitely impossible to think of.

Yan Liben smiled a little sorry when he was praised by the teacher. In his opinion, these are mainly Li Wangyou’s ideas, he is only realizing the master’s design.

But Yan Liben was very happy to get the masters affirmation. He pointed to the busy craftsman in front of the forging machine and said, “Master, please look at the top of the hammer and the base below. A stamping mold made by steel essence. The craftsman puts the cast copper bar on this mold, and when the hammer head drops by itself, a good copper coin is cast. Compared with the past coin casting, it is not easy It only needs a craftsman to control it. The teacher, Great Talent, really admires the discipline.”

Li Wangyou’s face is not red and his heart beats, accepting Yan Liben’s admiration, anyway, he also I am used to being so “flattered” by others, and my face is getting thicker.

He pretended to have a nodded smile, watching the craftsman coin.

As the water flow drove the waterwheel to rotate, the hammer head was raised high, and then fell heavily, with a loud bang, and it accurately hit the copper bar below.

The hammer head slowly lifted again, and a Copper Coin shimmering with metallic luster fell into the bamboo basket containing copper coins below, making a clear and pleasant sound.

Li Wangyou reached out and picked up the freshly baked Copper Coin. The words “Kaiyuan Tongbao” were evenly spaced, clear and powerful.

These four characters are not written by an ordinary person, but by the master of calligraphy, Ouyang Xun.

Li Wangyou took out a piece of official money from his purse for comparison.

The two coins are of the same weight, but different from the minted coins, the stamped coins are more refined and more metallic.

If you have to choose an official coin from these two coins, Li Wangyou believes that most people will choose the stamped coin.

“How many sets of this punching machine have been built?”

“There are already ten sets, and the others are still under construction.”

Li Wangyou silently After doing calculations, a hydraulic press can beat eight times in one minute, which means that eight coins are made.

There are 480 coins in one hour. If three shifts do not stop work a day, more than 5,700 coins can be suppressed, and ten coins can make 57 coins a day.

This is a huge difference from how I and Li Erboasting said that they could make a thousand coins a day.

However, this hydraulic forging machine can continue to be expanded. If there are 100 units, it will be able to produce more than 500 copper coins per day. If there are 200 units, then Nissan Qiankan will not be a problem.

“haha, Liben, you did better than what you thought as a teacher. Niu Wu, you immediately take my goldfish charm, go to Taiji Palace and find Mi Tuo. Let him tell His Highness to mint coins Its done, see if His Highness wants to check it in person. Go and come back quickly, Ill wait for you here.”

“No!” Niu Wu did not hesitate to take over Li Wangyous goldfish Character, run out of Workshop…
