The rise of the prince

Chapter 121 Iron and Steel

After Zhao Si's explanation, Li Ye suddenly realized, and at the same time realized that he did have knowledge beyond a thousand years, but practical experience is indispensable. It turned out that the carriage bearings had already had complete lubrication technology.

It is wrapped with animal leather plus a fat layer, and animal oil is applied on time, so that the lubrication effect is obvious and the bearings will not get stuck. Zhao Si, as a craftsman, naturally knows these things.

Animal leather is everywhere these days. Li Yeyanshen helped to get a piece of sheepskin that was peeled off directly. The inner layer still has subcutaneous fat, and then wrapped it on the stress point of the bearing, and added lard on the inner side, it was really lubricated. The effect came up all at once!

The huge wooden bearing is thicker than a human thigh. Li Ye asked Zhao Si to cut a hole in one end, and then added a cross wooden handle to let several servants rotate it in turn, so as to imitate the telekinetic transition of hydraulic drive.

These steps seem to be ridiculous, so don’t be careless. Feasibility experimental research is a must. Now that you find problems, you can slowly think about how to solve them.If you take it for granted and install it directly, when something goes wrong, all your efforts will be wasted and all will be thrown into the river.

Zhao Si and his servants didn't understand what he was going to do, and Li Ye didn't explain it, because it was only a part, and they didn't understand it when it was complicated, and they would understand when the real thing came out.

The so-called iron and steel does not mean iron mixed with carbon. This kind of statement is just a word in chemistry textbooks, because there is no natural pure iron in the world. After iron ore is smelted into pig iron, the carbon content still exceeds 2%, especially in this age of immature technology. It is estimated that there must be about 5%, and only those with a carbon content of less than 2% can be called steel.

In this day and age, because the temperature cannot reach the required limit, in fact, there is only one way to really smelt steel, which is repeated smelting and repeated beating to reduce its carbon content, which is the so-called [-]-smelting steel.

However, this process consumes a lot of manpower. It is conceivable that ordinary people will have arm pain after swiping a forging hammer of more than ten kilograms a dozen times, but now they have to forge hundreds of times, and this process has to be repeated hundreds of times. In order to produce good steel, people have to eat, drink, and rest, which shows that it takes a long time and consumes a lot of manpower and material resources.

With hydraulic forging, this problem can be solved.

Not to mention dozens of kilograms, a forging hammer of several hundred kilograms can be lifted up for you 24 hours a day and night.

The essential difference between iron and steel from an industrial point of view is that the carbon content of steel is lower, and in terms of physical properties, iron is stronger, but brittle and has poor plasticity.Steel has good plasticity, high strength, and low brittleness, which means it is more versatile.

Iron armor is impossible to have a full body armor, so it can only be arranged with iron armor pieces linked one by one, because although the shaping process is simplified according to the body contour, iron is easy to break and shatter, because although it is hard, it is also brittle , the strength is low, which is why steel will gradually replace iron.

Not only armor, ships, living utensils, etc., steel with good plasticity and high strength far exceeds iron. Therefore, if hydraulic forging is popularized, it is likely to break the world.

Because of Zhao Si's inspiration, he almost conquered the most difficult part of hydraulic forging at once, and Li Ye was even more confident, Zhao Si looked at these blueprints and said in doubt: "Your Majesty, is this going to build a big wheel? "

"That's right." Li Ye stood up and said, "Zhao Si, if there is something that can replace manpower to do something, is it good or bad?"

Zhao Si didn't expect him to ask such a question suddenly, he hesitated and said, "Of course it's good for a villain, and I often wish I could have more manpower when I'm working, but it's always bad for some people. If there is no food to eat, if there is something to replace it, they can only starve to death."

Li Ye nodded. The emergence of any new thing has resistance, but the resistance varies from big to small.

"Why don't you work for the palace in the future, how about I give you five pennies a month." Li Ye said to Zhao Si.

"Ah! What did the prince say?" Zhao Si couldn't believe his ears.

Li Ye said to him again: "I will pay you five pennies a month, and you will work for the palace in the future."

"Your Majesty is not joking with the villain." He still couldn't believe it, after all, five guan is still too much money, that is sixty guan a year, which is higher than the salary of the county magistrate!

"Of course I'm not joking. In the future, this yard will be where you work, and there may be other people." Li Ye said, he had a plan in his mind, and in his opinion, he could buy a skilled man like Zhao Si with this little money. Craftsmen are simply making money.

"How can it be done? Only the official has an office space." Zhao Si shook his head quickly and said.

"It wasn't given to you by the imperial court, it was given to you by the palace. What are you afraid of?" Li Ye said indifferently, and then continued: "Do you know any blacksmiths? You should be younger. The palace still needs a few blacksmiths."

Zhao Si nodded, and then asked puzzledly: "Why do you want to be young, young people are mostly not very good at craftsmanship, I'm afraid."

"It's okay. I'll pay according to my skills. If my skills reach your level of five pennies a month, then I'll reduce it. But don't exceed the age of 35." Li Ye has his own plan, he wants to start a new era, You can't use the old man.

This has psychological considerations, a very simple psychological phenomenon, like a girl who has been with a scumbag for a long time, and even if she finds out that he is a scumbag in the end, most of them will not choose to leave, but defend him, accept him, and wrong themselves .

Why is this?The answer is actually very simple. The cost already paid is too high, the investment is too high, and the price of giving up is too high.

The same is true for old craftsmen. They have honed their craftsmanship all their lives. Suddenly one day they told him that your craftsmanship is useless and there are things that can replace it. You learn new things from me. Their first reaction must be to maintain their inherent concepts and craftsmanship. , because too much has been paid and the cost is too high.

Therefore, if you want to innovate, you must use young people. Young people do not have such a high past cost.

"Master Wang really doesn't want to tell?" Zhong Daoyu wrinkled.

Wang Yue shook his head: "It's not that I don't say anything, it's just that my friend is low-key and never likes to make public."

Zhong Daoyu sighed: "Forget it, I have many questions I want to ask for advice." Then he got on his horse and left.

Looking at the back of him and his entourage going away, De Gongcai said in a low voice: "I really worry about that kid, if you can say that he is against it, so what, but at this time to say that the timing is not right, it is too much for him unfavorable."

The servants who were driving the carriage led the carriage and horses. De Gong boarded the carriage, but he couldn't help laughing when he thought of that kid. He had heard about the recent incidents in the court, but if he thought about it carefully, he knew the ins and outs of it, and he was not fooled. I'm afraid he's the only one in the dark.

In retrospect, the civil and military affairs of the whole dynasty were played by him without knowing it. He only knew that the wind direction changed suddenly and people's hearts were unpredictable, but he didn't understand the cause and effect. This method is really clever.

But what he was curious about was how the boy made He Zhao's idiot speak, and he would ask if he had time.
