I saw Sun Tiedong looking back and forth at the words recorded in the notebook, and asked Zhu Cihong several times, and understood the meaning of the new words one by one concept, so he nodded slowly and stopped his voice. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

There was silence in the room for a while, and everyone looked at the newly emerged young man, thinking about where the other party came from. Especially Zheng Anchun's face was blue for a while and red for a while, desperately wondering who this person was.

He really wanted to get back on the field. Especially in the iron-making industry, he claims to still have a bit of face.

It's just that the face of this person in front of me is tight, and it's the first time I've seen it. The other people obviously didn't recognize their expressions, so he couldn't figure out what the way was coming.

The only thing that can be somewhat certain is that this young man is standing against Tian Yingqi, and Tian Yingqi also stares at this young man from time to time, looking very nervous.

Thinking of the origin behind Tian Yingqi, Zheng Anchun decided to let the problem of technology belong to technology, and wanted to use other methods, I am afraid that the ending will be very bad.

At this point, Sun Tiedong finally opened his mouth: "What this son said is indeed every word. Although I heard many old words for the first time, these new words were understood for the first time. It's understandable, it's all understood, and that's right. These two problems are indeed problems. But ......"

Speaking of this, Sun Tiedong was slightly proud: "My Daming is not comparable to Xiyi." These problems have arisen, and I have solved them in my generation! ”

Sun Tiedong's solution not only has, but also has two ideas.

The first is to solve it when filling steel, that is, repeatedly filling steel. However, after pouring into the steel ball, the plasticity will deteriorate, and it is much more difficult to forge the wrought iron into iron bars and curl it.

The other is to improve the steel filling method.

That is where Sun Tiedong is more proud.

"Where the iron and steel refining method is to make thin slices of wrought iron, such as the width of the fingers, and the length of half an inch, the iron is tightly wrapped with the tip, the pig iron is placed in the soil, and the broken grass is covered on it, especially at this time, the mud is not fastened, and then the mud is coated under it. When the furnace blows the wind, when the fire arrives, the raw steel is first melted and soaked in wrought iron, and the two feelings are combined. Take out the hammer, and then refine and hammer again. Sun Tiedong shook his head, like a teacher.

In fact, at the beginning, he also wanted to write down this paragraph, and he didn't know how many times he shook his head, so he carefully memorized these technical points in his heart, and he would not receive a whip from the master.

As for the strange appearance of Mr. Teaching, it is not an exaggeration to say that such a craftsman is a high-level intellectual if he can read and write. At this moment, the sour scholar who is shaking his head looks much more powerful and advanced than the old craftsman who is speechless.

"This method is indeed good." Zhu Cihong groaned slightly, and said: "The wrought iron sheet is no longer fine, and it is also clear." Wrought iron pine naturally helps to allow carbon to penetrate into it. As for the pig iron placed on top of wrought iron, it seems that it also takes advantage of the gravity problem I just mentioned. Although our ancestors did not summarize these physical laws, their application in technology and engineering is very admirable. By using gravity, molten iron can also be allowed to penetrate into wrought iron. As for multiple forging, it is because the product no longer needs to be finely curled, so it can be repeated many times. ”

Seeing that Zhu Cihong understood so quickly, Sun Tiedong was even more surprised, he couldn't hold back the moving look on his face, but became modest: "Dare to ask Gongzi what he has to say?" ”

Seeing that Sun Tiedong had a correct attitude, Zhan Feiyu on the side was slightly glad that he didn't continue to interject too much. Otherwise, it's yourself who has no face at the moment.

For example, Zheng Anchun on the side had a cold face and didn't say a word, but he didn't dare to interject.

"I don't dare to be taught, I really have some of my own ideas." Of course, Zhu Cihong is not a technician in the steel industry, but he relies on the scientific literacy of modern people in his later generations, but he doesn't know how many times he has run back to the craftsman's compound. At present, after two or three years of hard work, the craftsman compound is not what it used to be, and the craftsmen from all over the country have collected a lot. Sun Tiedong's leader in such a profession is of course very powerful, but there are countless people in the craftsman compound who are not worse than Sun Tiedong.

It's not that this Sun Tiedong can't do it, but no matter how powerful Sun Tiedong is, he is also a leader in a large private workshop, relying on a few secret recipes. However, the craftsman compound has hundreds of top craftsmen who communicate with each other, and there are resources at the imperial level to support experimental research, and the progress can be described as a rapid progress. As the emperor who personally promoted all this, Zhu Cihong had never eaten pork and seen a pig run, so he could naturally beat Sun Tiedong.

What's more, Zhu Cihong also has the blessing of modern people's scientific literacy.

Just after a little silence, Zhu Cihong sorted out his thoughts and said: "There are indeed two problems. For example, wrought iron sheets with a thickness of more than one centimeter seem to have not been forged many times, although such iron sheets are loose and conducive to the penetration of carbon components, but in this way, the impurities in the iron will not be removed, and they need to be forged repeatedly and carefully. Those who are not tall and physically fit and experienced cannot do it. This point is not suitable for the production mode of the large workshop of Jingshi Iron and Steel Plant. ”

The production mode of the large workshop is to be easy to master, easy to promote, and able to operate in batches and in a standardized manner. Later generations once touted the craftsmanship of the Japanese and paid attention to ingenuity. For example, the hammer mobile phone has blown a wave of craftsmanship.

But no matter how powerful the craftsman is, it is also his own craft, which cannot be promoted, and can only be reduced to all things enjoyed by a few, and its high cost is destined to keep high-quality products away from ordinary people.

Zhu Cihong has no shortage of handmade, high-quality experimental models, what he needs is industrial products that can be mass-produced and mass-produced. Only in this way can quantitative changes be made qualitatively changed.

Imagine, if the cost of iron farming tools in the world drops to one-tenth, how much will it increase the country's grain output?

The idea was slightly withdrawn, and Zhu Cihong said again: "In addition, if the specification is increased to a length of 5 centimeters and a thickness of 1 centimeter, it is basically impossible for such an iron sheet to be completely carburized, especially the carburizing agent is molten iron." As for how tight is the iron sheet clamping wrought iron? If it is too tight, it is difficult for the molten iron to enter the gap between the wrought iron, which further aggravates the problem of incomplete carburizing. This point is also very well grasped by the school. This makes it harder to generalize. It is even more unsuitable for the production mode of Jingshi Iron and Steel Plant. Finally, the problem of inconsistency in the carbon content of the upper and lower parts of the finished product caused by gravity has not been solved. In other words, the whole problem is still not solved. ”

"This boy is really a man of God." Sun Tiedong sighed lightly and couldn't help but say: "That's right, this is the secret method of the old club in Nanzhili, and there is a solution." But...... But I can't tell the truth. Don't blame it. ”

On the side, Zheng Anchun breathed a heavy sigh of relief.

You must know that if Sun Tiedong told this secret in a fit of anger, then he would really have a lot of trouble going back this time.

In these years, many people who do business rely on the competitiveness of the first few hands without being exposed, and the fear of passing on the male to the female is that the technology will be exposed, and the rice bowl given by the ancestors will not be able to eat.

This Zheng Anchun is a native of She County, Huizhou, and later migrated to Suzhou. The Zheng family has been doing this iron-making business since the Jiajing period, and it has been decades since then, so naturally they have their own unique skills.

This unique skill is the Sugang method.

The Taihu Lake basin has small iron ore reserves and has not historically been a major steel production base. But when it comes to ironmaking, you can't bypass Jiangnan. The later generations of Baoshan Iron and Steel represent the combination of capital, technology and market. Similarly, at this time in the Ming Dynasty, there was also such a situation.

An example of this is the Sugang method.

Overall, Daming's current ironmaking is high output and low quality, but in terms of quality, there is an exception for Suzhou Iron and Steel.

"Since Ouye forged swords, Wuzhong ironworkers are endless." Zhu Cihong praised: "The wonder of Sugang is indeed amazing. But...... This method is not the best method. ”

As soon as Zhu Cihong's words came out, Zheng Anchun, who had already held back and didn't want to come out and open his mouth again, finally couldn't help it, he was angry and jealous and said: "What we said just now is just about filling steel, this brother thinks it's just that. Now when it comes to Su Gangfa, this brother still doesn't think so. Then you ......"

Sun Tiedong suddenly coughed lightly and said, "Please also ask this son's subordinates to be merciful." ”

On the side, Zheng Anchun's eyes widened, and he really couldn't understand that the technical master with a strange temper and stubborn personality would bow his head to a young man one day.

What's more, obviously, according to Sun Tiedong's words, it means that Zhu Cihong actually knows the Sugang Law!

Sun Tiedong didn't know whether Zhu Cihong knew about Su Gangfa, but what he could be sure of was ...... There is a great chance that Zhu Cihong said today that the world's steel industry will have turbulent waves.

It's just that the emergence of this Jingshi Iron and Steel Plant alone is actually the beginning of the transformation of the steel industry. As for this, Sun Tiedong obviously doesn't know.

Zhu Cihong obviously didn't intend to show mercy, he slowly shook his head and said: "The Sugang method is indeed a method that surpasses the steel filling method. Put the wrought iron material into the furnace and heat it by blast air, and then put one end of the pig iron obliquely into the blast furnace mouth to heat. When the temperature in the furnace reaches 1,300 degrees Celsius, the pig iron in the furnace continues to melt and fall, and the wrought iron material is softened, and then the pig iron block is clamped with pliers, so that the molten iron is evenly poured onto the wrought iron. After the pouring is completed, the air blast is closed, and the steel ball is clamped and hammered on the anvil to remove impurities. If twice is better, am I right? ”

Sun Tiedong sat down dejectedly, arched his hands, and was silent. He knew very well that Zhu Cihong was right. Not only is it right, but many details are exquisitely done. In other words, they are not stealing secrets, but developing their own technology. For example, the 1,300 degrees Celsius, even they don't have it themselves.

Obviously, this is a powerful being that simply surpasses itself technologically. If the other party is stealing technology, then he will still struggle, thinking that he is full of righteousness and will not back down.

But...... If the other party is an upright technology developed by himself, then there is really nothing to say, only to admit it.

When he thought of being serious, Sun Tiedong was full of lawsuits.

As for Zheng Anchun on the other side, his eyes widened even more, he looked at the family members brought over behind him, and stared at the few people in front of him, constantly thinking about what to do.

This is the top secret of the entire family.

Right now, it's leaking here!

When you go back, what will your family think? I'm afraid I will only think that they will leak secrets!

But they never did anything like that.

In any case, the secret of the entire family has been leaked, and the jobs of several generations are equivalent to being smashed at this moment.

"This problem has to be solved! Otherwise, when I go home this time, I'm afraid I don't want to leave a full beard and a full tail! Zheng Anchun kept thinking about how to deal with it in his mind, and his eyes gradually became fierce.

Obviously, he was already planning to kill people directly!

How could Zhu Cihong not know about cutting off people's financial routes, such as killing his parents?

It's just that Zhu Cihong knows very well that this is no longer a secret at all. Although, according to the original historical development, this Suzhou steel method will not gradually spread until the Qing Dynasty to replace the steel filling method, but once the Jingshi Iron and Steel Plant is developed, these small workshops with backward technology will not have a place to survive.

Sugang method is already semi-public.

In the past, the development of Ming technology was slow, and after a thousand years, there was a Suzhou steel method to replace the steel filling method, so that it was surpassed and backward by the Westerners.

And now, with Zhu Cihong's craftsman compound to push down this Sugang method and study it, it is really a common thing. Zhu Cihong can know this, not because Zhu Cihong is a technical talent who defy the sky, but because the papers that have been formed in the craftsman compound have been published in a state of secrecy, and the "Nature" magazine published by the craftsman compound itself.

At present, the scale of the craftsman compound has become larger and larger, and the management needs to be standardized and scientific more and more. On this basis, scientific research journals came into being and became a platform for the exchange of technology.

It was only a matter of time before the paper on the Sugang method was published in Nature and eventually bought into the practical stage. Zhu Cihong's leak was just a little bit earlier.

At this moment, there was silence on the field, and everyone had a premonition that something was wrong when they heard Zhu Cihong tell the secret of such a fortune. I had a thoughtful plan to quietly write down the main points that Zhu Cihong had just revealed.

Even if you don't plan to do anything, you know that a storm is brewing.

"The steelmaking industry is a capital-intensive, technology-intensive industry. Such a behemoth's world cannot be compared to a more powerful existence without enough strength and ambition. Zhu Cihong said slowly,

"Hey, that's a nice thing to say. This Jingshi Iron and Steel Plant is different or will it fall? Zheng Anchun laughed, smiling playfully. After all, he couldn't help Zhu Cihong's wild words.

"Oh?" Zhu Cihong pursed his lips slightly and said with a smile: "If I don't have a solution, how can I be here?" ”

Fang Yizhi, who had not spoken, finally couldn't help but speak: "Who is Your Excellency?" (To be continued.) )
