(Chapter 153 is gone, I'm really panicked, and the commune plot is over.) ）

After the work of the commune was carried out, Yan Zheng also began to pay close attention to industry.

The agricultural population in Meaux has been arranged out of Meadow, and only the industrial population is left in Meoc, and there are some people who breed pigs and cattle.

In total, there are more than 2,000 workers and their families, and the number of male workers has increased to more than 500.

It's just that there are not so many positions for the families of these people, so among these family members, they still need to be engaged in agricultural production.

This is actually a very high number, if it weren't for the fact that taxes could be collected from the surrounding tribes, Yan Zheng would not dare to let so many people engage in industrial production.

After this expansion of workers, the first iron and steel plant expanded its production capacity again, the number of workers reached 150, and the first machine factory and the first textile factory were established.

Among them, the first machinery factory really started the initial standardized production.

The process of producing foot-operated threshers is probably the production of various semi-finished parts from the carpentry factory and the steel factory, and then sent to the first machine factory for assembly.

At the same time, Yan Zheng put on the pressure boiler again, and after the trial production of the First Iron and Steel Plant, he successfully built three large and small pressure boiler machines.

When the pressure cooker is built, the production of iron pots becomes extremely simple, only need to pour molten iron and press it with a press cooker.

This also uses a certain iron mold principle, as well as the principle of water cooling, in the core components of the pressure cooker, it can be filled with water to achieve the purpose of rapid cooling, so that the strength of the pot will be higher.

Although it can't compare to the 18,000-hammer Zhangqiu iron pot, this pot is durable, and it is not difficult to produce at all!

As long as the source of pig iron is stable, hundreds of such pressure cookers can be launched, which can impact the iron pot industry in Daming!

……………

"Shenzi, we have solved the problem of iron mold casting cannon and water cooling of the inner mold!"

Yan Zheng went to inspect the factories as usual, and as soon as he arrived at the No. 1 Iron and Steel Plant, Tiemu Needle smiled and invited credit.

"Solved? It's true? Is it now possible to cool the inside faster than the outside? Yan Zheng was also surprised.

The iron wood needle held an inner core and placed it in front of Yan Zheng.

While displaying, he explained: "This is a whim of the pottery people, using a large container at the top, filling a sufficient amount of water, and then using a bamboo tube, placed in it, by sucking it with the mouth, the superheated water in the inner core can be replaced by cold water."

After Yan Zheng looked at it for a while, he immediately understood the principle.

He looked at the ironwood needle and said, "Whimsy, admiration, admiration!"

Tiemu Needle also smiled and said: "Actually, it's not as difficult as Shenzi said, just think about replacing the overheated water inside, so that the inside can be cooled quickly."

Yan Zheng fiddled with it, this device is very simple, that is, a large container is cast on the top of the inner core, as long as there is water in it, it can turn hot water into cold water through the simplest replacement.

"I'm giving you a trick, you go find a piece of leather, sew it into a tube, then you can use the siphon principle to achieve water circulation faster!"

"What is the siphon principle?" Ironwood asked.

"It's a principle that allows water to flow out continuously, but only if one end is lower than the other! You just do what I say. ”

"Okay!" Tiemu Needle smiled and said, "Son of God, then our cannon can be let go of the construction, right?"

Yan Zheng shook his head and said: "There is no need to build it on a large scale, you can make another batch, as long as you ensure that you have this technology!"

"And there's one more thing you need to do, and it's a little simpler than the others, you go and try to make a batch of springs!"

"Spring?" Ironwood needles were a little puzzled.

Yan Zheng explained: "You should understand that iron also has toughness, toughness is elasticity, but I want to get iron with higher elasticity." There are two methods, one is drawn into a circle, and the other is a spring sheet. You only need to add some inconsistencies to it when making iron, and after many tests, you can always find a reasonable ratio! ”

"What is a child?" Ironwood asked again.

Yan Zheng smiled and said, "Wu Yizi is an alloy that contains a lot of rare metals that can change the properties of steel. You don't need to know so much, just know that spring steel can be used to produce more powerful weapons, as well as faster weaving! ”

"I'll go to the Red Room to pick it up later, remember, don't put too much at once, just put it little by little!"

Tiemu nodded and took the developed inner mold to give the task.

Yan Zheng looked at his back and felt very happy.

What is he instilling in these workers these days? Isn't it inductive and deductive, analytical and synthetic, abstract and concrete, logical and historical?

These are all Ma Zhezhong's thinking methods on how to understand the world as a dialectical materialist.

In epistemology, the process of cognition defined by Ma Zhe is from practice to cognition, from recognition to practice, and then from practice to cognition, and this process is infinitely cyclical and developing.

Therefore, the core of epistemology is the unity of subjectivity and objectivity, and it is only in practice that our ideal results are achieved that our understanding is confirmed.

And in the continuous practice and understanding, everyone can continue to deepen their understanding of things and the world.

From this point of view, ironwood needles, the workers of the steel mill, have already accumulated a certain amount of experience in steel-related things in their daily work.

They relied on some understanding and assumptions, and then borrowed from the experiences and assumptions of others, to create an ideal thing.

It's not an easy skill, it's already creative.

And beyond many people's expectations, in scientific research, the most common method is actually the exhaustive method, that is, knowing a way of thinking, and then constantly experimenting, trying again and again, and finally getting the desired result, it can be regarded as success.

This method is also a method adopted by Yan Zhenghui for a long time and on a large scale, because he knows the right direction of some scientific development, as long as he takes these people on the road, then relying on the exhaustive method, he will one day get the correct result.

Coming out of the steel factory, Yan Zheng was in a particularly good mood, and he came to the newly established pig breeding station.

Here there are also students who start to take charge of the internship, they number the individual boars, so that the different boars and sows xx.

One of the highlights is the crossbreeding of the native domesticated wild boar with the Taihu pig.

Yan Zheng attaches great importance to the pig breeding business, and also entrusts the Song family at a high price, asking them to collect pig breeds for themselves, especially the big white pigs in Jiangxi and the black and white pigs in Guangdong.

These two kinds of pigs are the bearers of the hybrid world, compatible with many advantages, if more hybridization, to make a more powerful pig breed, Yan Zheng alone by raising pigs, can go down in history!

"Hello teacher!" As soon as they entered the breeding station, several students bowed obediently.

After Yan Zheng nodded in response, he came to several sows waiting to give birth.

After checking it once, I asked: "Do you remember the relevant precautions for sow delivery and postpartum care?"

A few students said a few things very neatly, and brought a pamphlet from not far away, indicating that they were familiar with everything.

Yan Zheng nodded with satisfaction and said, "Pig, this thing is about eating meat and agriculture!" The beans grown every year are used to raise pigs, and there is a lot of pig manure! When there is more manure, there will be more compost, and the agricultural output will be greater! ”

"Many things seem to be unrelated, but they are actually very related! There are so many excellent pig breeds in the Ming Kingdom, if there are scholars who organize crossbreeding, I am afraid that they will have already obtained excellent pig breeds! And with excellent pig breeds, not only can the people eat more meat, but also get more manure, and they can grow more food! ”

"With food and meat, the people will naturally grow stronger and healthier! In this way, will not the national strength be greatly increased? What a pity! I am in China, from the Tang and Song dynasties to the Ming Dynasty, for more than a thousand years, Confucian scholars will not care about these little things, I am afraid that when they hear the word hybridization, they will immediately write an article to criticize, to scold this is immoral, vulgar and unbearable! ”
