Chapter 195 People who are ahead of the times 2
Over the past few years, through countless on-site practices, we have summarized the ingredient lists of more than ten steels with different properties. I can’t say that they have been successful every time, but they are still close to the same.

Every time he figured out a new ingredient list or tried out a finished product with brand-new properties, he was happy for a long time. He felt full of accomplishment and full of energy. He immediately went to figure out the next one and never tired of it.

The person who brought him into the new world was the young emperor in front of him. In his mind, the emperor was both a king and a teacher. As a subject, he must be loyal to the king, and as a student, he must respect his teacher.

But regardless of loyalty or respect, leaving so much coal and iron in Xishan without mining and utilizing it, and insisting on opening new mines and building new factories hundreds of miles away is completely unreasonable and must be clarified.

"A lot? Hahaha... Zhenzhi, you are looking at the sky from a well. Compared with the coal and iron in Kaipingwei and Luanzhou, Xishan can only be considered a small sesame. The imperial court is planning a new policy, and there will be many car factories, weaving factories, and agricultural tools. Factories, fertilizer factories, soap factories, and sugar mills were newly built, and the demand for lime and steel was very high.

The lime kiln does not have much technology and is too labor-intensive. I plan to leave it to businessmen from all over the country to operate it. However, the steel plant is an important weapon of the country and cannot be given away easily. I can only suffer you a little longer. "

As a graduate of the Iron and Steel Institute, Hong Tao must know the quality of Xishan's coal and iron.Moreover, the Yongding River is too close to the capital and is often exposed to floods. It is not suitable to build a large-scale comprehensive factory area. The most suitable alternative area is the Kailuan Mine in later generations.

"I understand, I will arrange manpower immediately after returning, and I will live up to the emperor's wish!" After hearing the emperor's explanation, Li Zhizao accepted the order happily, regardless of the content of the new policy or where to build the factory.

"Are there any difficulties?" Hong Tao likes people who only care about the work at hand. As a technical official, it is best not to get involved in politics. He can't play with politicians at all, and his own strengths are wasted. Fall well.

"...It would be best if we could add more people." Li Zhizao didn't show any pretense. He thought about it for a while and really wanted to come up with something, but he didn't have enough confidence when he mentioned it.The emperor has always opposed hiring local farmers to mine coal and only allows selection among refugees.

However, the composition of the refugees is too complex, their moral character is mixed, and there is not even one out of ten who is hard-working and willing to work, which seriously slows down the production progress.Without the help of the imperial concubine’s family, he would not be able to take care of it on his own.

"Manpower is easy to handle. You first go to the site for prospecting. Soon there will be a large number of young people to choose from." If Li Zhizao made this request last month, Hong Tao really had no good solution, but now not only does he have it, but also Full tube.

As long as Liaodong begins to evacuate, some local Han people will definitely enter the customs. It is unrealistic to allocate land immediately. New factories in various places are a good place to arrange them.

"Then I have no difficulty. It's just that your Majesty talked about steel that never rusts last time. I've been thinking about it for a long time and still haven't found anything. Can you tell me again?"

It was still the same as before, as long as the emperor said he could solve Li Zhizao, he would stop asking questions.But he doesn’t care about everything, such as novel ingredients. Even if he has heard it once, he still wants to hear it again.

"It's not urgent. You go and call Zhao Shizhen. I still have something to tell you. I'll talk about it when I have some free time!" But Hong Tao is really not in the mood to chat about stainless steel. That thing can't be made with the current smelting technology. Even if It’s no use knowing the ingredient list.

"Your Majesty, I have a gift to offer!" Unlike Li Zhizao, who boarded the carriage empty-handed, Zhao Shizhen is worthy of being a second-generation official. He practices boyish skills in terms of human relations and sophistication. Even if his talent is not good, he still gains something. "Bring it up!" Although the people who were summoned were all the emperor's cronies, the accompanying Han general of the Imperial Guard still strictly enforced the rules and no items except people were allowed to approach.

"Bang..." What was brought up by the Han general were two boxes. They looked similar in appearance and were woven with wattle thorns, one and a half feet square.But the weight was obviously different. One of the boxes was so heavy that it almost knocked the strong, muscular general from his waist and hit the carriage floor with a loud clang.

"This is..." According to the rules, unknown objects cannot be touched by the emperor himself. Wang Chengen immediately stood up and opened the lid of the box, and then he was dumbfounded.

There is a greasy iron lump placed neatly in the box. It is round or square. There are several deep grooves around it, which seem to be called threads, but they are not the same as the bolts used in carriages. They are broken. It's open.

"Well, it looks good... have you tried it?" Seeing this thing, the emperor also stood up and came over, looked left and right, and if it wasn't too greasy, he picked it up and turned it over with his hands.

"Reporting to your Majesty, I have been trying it for [-] years. Except for the softness and hardness of the copper ring, it is a bit unsatisfactory. The effect is no different from ordinary front-loading artillery. But it saves many steps when loading, and it is more than twice as fast!"

Zhao Shizhen smiled brightly. As he answered, he picked up two pieces of paper from the box and gestured at the patterns on them. His expression seemed to be a promise to the emperor to introduce the new candidate to the palace.

"Arrange production as soon as possible. I will say hello to Li Zhizao and Xu Guangqi, and ask the iron factory and machinery factory to fully cooperate." The emperor also nodded while listening, patting the iron bump and actually laughed. His movements and eyes were much better than what he saw. The concubine is still beautiful.

With this iron knot, artillery can truly become the king of war.Its full name is the broken threaded breech. It is a key component of the breech-loaded artillery. Its function is to facilitate the insertion of shells from the rear of the barrel and ensure good air tightness.

Europeans have had the idea of ​​breech-loading cannons for a long time. The Franco machine gun used by the Portuguese in the 16th century was essentially a breech-loading cannon.Its advantage is its fast rate of fire, but its shortcomings are also obvious: insufficient air tightness, resulting in relatively weak range and power, and cannot compete with the front-loaded smoothbore guns of the same period.

But the Europeans did not give up and kept experimenting and exploring. After more than 300 years of research, they finally came up with the breech block, which completely solved the airtight problem of the breech-mounted gun barrel.

The original breechblocks were divided into two broad categories, wedged and threaded.As the name suggests, a wedge-like steel block is plugged into the back of the barrel, and the chamber pressure inside the barrel is used to squeeze the copper metal ring to deform and seal. This is called a wedge-shaped breech block.

To put it simply, a threaded breech bolt is a large bolt with a diameter similar to the inner bore of the gun barrel. It is threaded into the back of the gun barrel to achieve a sealing effect.

In terms of air tightness, the threaded breech block is more effective than the wedge-shaped breech block and is also lighter in weight.However, it is more difficult to process and complex to operate. You have to screw the thread to the end every time to load the shell, and then tighten it again. The rate of fire is far inferior to that of the wedge-shaped breech block, and it is more suitable for use in large calibers that do not require a rate of fire. On the artillery.
