Chapter 132: The Difficulty of Making Steel

When he came to this era, Zhu Zhanji knew that Liu Bowen was actually not as divine as he said in the romance, and his role in the entire structure of the Ming Dynasty was not particularly large.

Otherwise, he would only be made an earl, and one Hu Weiyong would be able to kill his son and drive him home. There are even rumors that even his death is inseparable from Hu Weiyong.

The eldest son was killed, and the second son hanged himself because of his opposition to Zhu Di.

But Liu Bowen's talent and ability must be there, after all, he has a family history and an official family. Otherwise, the entire Liu family could have started from the Song Dynasty, passed through the entire Yuan Dynasty, and was still very good until the beginning of the Ming Dynasty.

Liu Jie's actions today are out of bounds in officialdom and are very bad behaviors. There are no rules, there is no circle, as a person in the officialdom, he does not follow the rules, do you still expect the small people to abide by the rules?

But after knowing that he was Liu Bowen's descendant, Zhu Zhanji was able to understand him.

Because of the relationship between his second grandfather, Zhu Di has no good impression of the Liu family. The emperor's disgust will also put Liu Jie in a difficult situation.

As the only remaining officialdom seedling of the Liu family, in order to protect the family, he had to accept staying in the capital with a cold eye, and if he wanted to get ahead, he had to pay more than others.

In the reception room, Zhu Zhanji glanced at Liu Jie, whose face was a little haggard, and his heart was full of sympathy.

He is only in his early thirties this year, and he is handsome, but he does not look high-spirited at all, but a little old-looking.

Because he has a long beard that is not like a civil official, but a short mustache like a military general, if he can be worthy of the title of a handsome uncle in the entertainment industry in later generations.

Zhu Zhanji took the lead in sitting on the chair and pointed to the chair opposite. "Sit down, if there is anything you need help with, just say it."

Liu Jie took out a book from his sleeve, knelt on the ground, raised his hands above his head and said: "The minister is fortunate to be in the Ministry of Industry Yu Hengqing Officials Lang, in charge of the affairs of the Patent Department, but he has never been able to pay attention to the essentials of the Patent Division, and he is trembling. I met His Highness today, just to ask His Highness for a strategy and relieve the worries of his ministers. ”

Hearing this, Zhu Zhanji understood.

The patent law was proposed by himself, and Zhu Di was also very interested in this suggestion, because he also wanted to know how much technology could be carried forward and benefited the people.

Nowadays, whether it is a craftsman or a businessman, including those who heal the sick, or even the gentleman who teaches, they all like to keep their hands.

And the emergence of patents, although it will create a monopoly in the short term, but what about ten years later?

When the first batch of patents expires, Daming can promote these new technologies for the benefit of the people.

However, this matter was handed over to the Ministry of Industry, and although Zhu Zhanji dealt with the Ministry of Industry every day, he could not get involved in their internal affairs, so he did not take care of this matter later.

Now Liu Jie comes to ask for advice, although it is not in accordance with the rules, Zhu Zhanji is still very happy in his heart, because he is willing to think, study, and progress.

Zhu Zhanji is not afraid that he will do something wrong, but he is afraid that he will not do things and get by, delaying the development of Daming.

So Zhu Zhanji's attitude was kind, he took the piece with his own hands, held his arm and said, "Wailang, please get up." The great-ancestor was a scholar of heaven and man, and although Zhan Ji was not seen, he was also admired. Hurry up, please, and I'll talk to you when I'm done reading the piece. ”

Liu Jie didn't dare to let Zhu Zhanji help him, so he quickly got up from the ground, and half of his buttocks were on the edge of the chair.

Zhu Zhanji opened the piece and looked at it carefully.

Liu Jie's recital is a work report, which is completely different from the exhortation recital, there are not so many elaborate formats, gorgeous words, and there is no need to be four-six.

However, Liu Jie's work report is also brilliantly written, and the problems he encountered are explained in a very quaint way.

However, this made Zhu Zhanji a little headache, and many places had to be guessed.

He can't ask others yet, and when he asks, he exposes his own shortcomings.

However, even so, he did not regret that he did not learn the ancient Chinese well, and when he ascended the throne, in addition to literature, he must implement the vernacular language, simplify complex things, so that the common people can also understand and understand the official documents of the government.

There is also punctuation, and now there are some books imported from abroad in the Ming Dynasty, with punctuation, but it is impossible to promote it.

First of all, these punctuation marks are still immature, and secondly, Confucianism relies on monopolizing academics to grasp the right to speak, and they are the most unwilling for ordinary people to understand culture.

Liu Jie's recital mainly talks about three problems, one is that wealthy families, wealthy businessmen, and a large number of patents, lest patents become their monopoly on academics and even technology in the future, which is not conducive to the development of people's livelihood.

Secondly, there are a large number of duplicate applications, which make many patents overlap, resulting in a lack of knowledge of which patent to grant.

The last point was that the patent department was understaffed and there was a lack of communication between the various states, which led to the duplication of patent applications. Some geographically restrictive patents cannot be compared at all, and there are many cases of duplicate approvals.

Zhu Zhanji had already considered this, put it away and said: "There is no need for anyone to apply for a patent, and there is only a need to investigate the source of the patent before it is necessary, and whether there is any forcible patenting." In the future, it is necessary to pay attention to preventing these wealthy businessmen from using the means of continuing to apply for relevant patents to continue to monopolize technology. ”

Liu Jie is very smart and directly grasped the meaning of Zhu Zhanji's words. "Your Highness is saying that if you give everyone ten years to toss, the real development of the Ming Dynasty will be after ten years?"

Zhu Zhanji nodded with a smile and said: "It is a Confucian habit to hide from generation to generation, and this habit has been deeply rooted in everyone's bones. Patents are certainly a monopoly on technology, but they are also an important means of changing this perception.

As long as this decade has passed, the internal supervision will definitely make extensive use of these patented technologies and will spread these technologies. But it's good that you know this matter in your heart, and don't make it public. ”

Liu Jie hurriedly responded.

Zhu Zhanji also said: "Those technologies have overlapping patents, so applicants can make physical objects, compare them with each other, and grant patents with the best one. However, other companies can grant franchises, which does not contradict patent monopolies. ”

"As for the last point...... Zhu Zhanji thought for a while before saying: "The Patent Division is understaffed, so it can continue to expand its scale and increase its funds." Patent divisions should be making a lot of money these days, right? ”

Liu Jie replied: "The Patent Department is only in charge of approval, and all accounts are still managed by the Ministry of Industry. ”

Zhu Zhanji shook his head and said: "This matter is not appropriate, the special funds are earmarked, and the Patent Department should not become a yamen for profit, but also a yamen for the promotion of technology in the Ming Dynasty." After you go back, you write a strategy and prepare carefully, and I will also negotiate with the two Shangshu at the right time. ”

He was about to thank him, but he heard Zhu Zhanji say again: "Young Eunuch Li, give the Taisun Order to the Wailang Member." In the future, if there is any difficulty, even if you come to me, as long as you work with your heart, it will not be difficult to restore the glory of sincerity. ”

Liu Jie knelt on the ground with a thud, his eyes were red, his lips trembled for a long time, and finally he buried his head deeply. "The minister must bow down and die."

Coming out of the living room, the person in charge of the engineering department and the internal supervision of the smelting plant stood at the door, and after saluting, he greeted Zhu Zhanji into the smelting workshop after a short greeting.

However, no one dared to let Zhu Zhanji personally walk to the side of the smelting furnace, and he could only observe the fire of the smelting furnace from a distance.

The furnace temperature is the biggest constraint of ancient steelmaking, the temperature of ordinary flames is only a few hundred degrees, and the temperature of steelmaking furnaces is at least 1,000 degrees.

In the Western Han Dynasty, Huaxia invented a high-temperature iron-making furnace that could make the furnace temperature reach 1,200 degrees, but for more than 1,000 years since then, this technology has been stuck here.

No matter what raw material is used, it is difficult for the furnace temperature to rise again.

Therefore, the ancient steelmaking was not a steelmaking furnace that could reach a temperature of 2,000 degrees in later generations, whether it was iron or steel, it was semi-liquid, not real molten iron or molten steel.

Then, this iron needs manpower to stir, forge, and increase the carbon content to make it into steel, so this process is also called frying steel.

This process has been going on for more than a thousand years, and the biggest challenge is how to increase the oxygen content in the flame and make it warmer.

Although the Han Dynasty had already learned to use water drains to add air to the steelmaking furnace, this air was ordinary air and the oxygen content was far from enough.

Before the invention of oxygen purification equipment, the furnace temperature could not go up. If the furnace temperature cannot be raised, the molten iron cannot become a real liquid, because the melting point of iron is more than 1,500 degrees.

Zhu Zhanji had no way to solve this point, so he could only remind these craftsmen to experiment with various gas supply equipment.

Although it is just an ordinary steelmaking furnace, it repeatedly carries out top blowing, side blowing, bottom blowing tests, and even three methods are implemented together to increase the temperature in the furnace.

Today, the furnace is fitted with three water drains and blows air into the furnace at the same time, which does have some effect, because the molten iron melts better than before.

The inverted flame furnace is a new type of steelmaking furnace developed in the Song Dynasty, which is divided into two parts, the frying chamber is built below the ground and the combustion chamber is built above the ground.

The two chambers are superimposed up and down, the bottom of the combustion chamber is facing the center of the refining chamber, the wind is blown in from the upper part of the combustion chamber, and then directly into the refining chamber through the fire port at the bottom of the combustion chamber. The top of the combustion chamber is closed with a cover plate to maintain the temperature.

Like the current copper cannons of the Shenji Battalion, almost all of them are cast by this method, but the melting point of the paste is higher, so the procedure of frying steel is indispensable.

Today, I tried two more methods, but neither of them could achieve the desired results.

Zhu Zhanji was not discouraged, and when he left, he proposed another way, that is, to use cement to cast a combustion chamber underground, then use refractory soil to insulate the heat, and add another combustion chamber under the current frying chamber.

There are combustion chambers up and down, and then two water drains to blow the air, which should have a certain effect.

He moved his mouth, and the people below were going to be tired and break their legs, and it would be difficult to complete the renovation of the furnace room in less than a month.
