In the Jingshi Iron and Steel Plant, Tian Yingqi quickly understood the whole story. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

And everyone also pinned their expectations on Tian Yingqi. Tian Yingqi can be described as a strange woman with a mysterious origin to them. He was the one who went around contacting the ironworks.

Most of them are in the ironmaking industry, and they don't know Tian Yingqi's specific identity, but they just understand that Jingshi Iron and Steel Plant was able to win the original brand of Zunhua Iron Smelting Plant, relying on Tian Yingqi's ability.

Obviously, Tian Yingqi has a relationship in the government.

"Which of the Privy Councillors is here?" Tian Yingqi didn't speak in a hurry, but asked Xiang Ganren.

"Wait a minute, Mrs. Tian, this living room is a little too noisy. I think it's better to change places. Lao Li, take a few distinguished guests from the coal yard and the mine to eat first. At this moment, a man who had made everyone in the house anxious to wait.

Everyone looked over and found that it was Fang Yizhi.

"Zheng Anchun, Zheng Gongzi, Zhan Feiyu, Zhan Gongzi, no matter what you plan to say, there is no reason to say it in front of outsiders, right?" Fang Yizhi turned his head and looked at the two of them.

Zheng Anchun and Zhan Feiyu are the representatives of the two partners found by Tian Yingqi. Both of them are outstanding iron-making families in the Ming Dynasty, with great fame in Haiyang and other places, and they are also wealthy. It's just that the businessmen of the Ming Dynasty have always been criticized, and the government naturally looks down on business, so Zhu Cihong gradually got better after he took power.

Rao is like this, the two families are also very worried, at this moment, seeing such a big incident in the iron field, Fang Yizhi closed the door again, and suddenly became anxious, for fear that the family property would be swallowed.

Zheng Anchun stared at Fang Yizhi with his eyebrows, wanting to cure the factory director who didn't take himself seriously, but when he thought that he was bringing outsiders to make trouble with his iron factory, he couldn't help it.

Seeing the cause and effect, Tian Yingqi said slowly: "A few colleagues from the coal yard of the mine, please have dinner first." As for the final payment, you don't have to worry. The loan of 500,000 yuan from Jingshi Iron and Steel Plant was handled by me when I was in Hengxin Qianzhuang, and Jingshi Iron and Steel Plant was a high-quality customer that Hengxin Qianzhuang trusted. Relax, everyone. ”

The suppliers glanced at each other, but they pondered the taste in their hearts.

There were even a few SX coal yard owners who exclaimed in a low voice: "Isn't this the Mrs. Tian from Hengxin Commercial Bank?" I even came here today. ”

"Mrs. Tian of Hengxin Commercial Bank?"

"That's right, to be precise, it was the shopkeeper of the Jingshi branch of Hengxin Qianzhuang before. I heard that I only met Gao Sheng when he went to SX. I didn't expect it to be here. ”

"It seems that with the guarantee of Hengxin Money, we can relax for the time being. Speaking of which, my stomach is also a little hungry. In this way, I will bother you. ”

Several vendors put smiles on their faces. If the Jingshi Iron and Steel Plant was really likely to die at any time, of course they wouldn't be so easy to talk to, and they couldn't wait to beckon dozens of people under their command to come over and grab whatever they grabbed to make up for the loss.

But at this moment, when they heard that there was a guarantee from Hengxin behind them, everyone was relieved, and their impression was refreshed.

A few vendors left, and the room was a little quieter.

At this time, Fang Yizhi led everyone into the inner room, and after sitting down, he said: "I also recognize the person from the Privy Council, it is Wang Zhiyong. This one is an old expert. I owe his help when I began to write "A Little Knowledge of Physics" in the year of Xin Weinian, that is, fourteen years ago, and I discussed with him what I said. This time, there is no problem that the iron smelted by the Jingshi Iron and Steel Plant has not passed the acceptance of the Privy Council, and it is not a matter of eating and taking, it is completely a quality problem. ”

After speaking, Fang Yizhi's face was full of pain.

Hearing that it was just a simple quality problem, Tian Yingqi was also a little silent.

If the Privy Council is going to make a fortune from this, it will be easy to do, and it will be enough to investigate the corrupt and pervert. After all, the war is about to start now, and if there is a problem with the supply of raw materials, it is the sin of killing the head.

But if the problem lies in the production quality of Jingshi Iron and Steel Plant, then it is still up to Jingshi Iron and Steel Plant to find a way to solve it.

Tian Yingqi wanted to say something, but suddenly his eyes widened, and a pair of beautiful eyes widened suddenly, and he quickly calmed down. A man dressed in an ordinary cotton robe stood beside her and whispered, "In a moment, just take me as your retinue and let me take a good look at the steel factory." Today, you don't have to make a noise, if you make a chicken and a dog jump, it will be your sin. ”

The person who came was Zhu Cihong, he didn't know when he had already entered the factory director's office, listening to everyone's conversation, and was very interested. Especially for Fang Yizhi, it seems to be refreshing.

This Fang Yizhi is not a sour Confucian.

It's just that Fang Yizhi's self-criticism made Zheng Anchun furious.

"Fang Yizhi, do you know how to make iron? This is the leading steel filling method in my country! Zheng Anchun looked incredulous.

On the other side, Zhan Feiyu glanced at Sun Tiedong, and saw that Sun Tiedong also looked disappreciative, and let out a soft cold snort, and suddenly had a first in his heart.

"If you don't have the ability, say it calmly, then we have to say a true hero and a good man. But if you push this matter on the technical side, it will be ridiculous and generous! Zhan Feiyu also followed.

Indeed, the steel filling method can be described as a very epoch-making key technology, and it is also the pride of these people. The reason why the two of them didn't say anything about being world-leading was that both of them were very proud that this was the land of China.

For future generations, if a technology is led by the United States, it is basically a global leader, and the world is ahead.

For the two people who are convinced that Chinese civilization is the leader in the world, they naturally do not want to take overseas people seriously.

Having said that, if you want to talk about the steel-filling method, you have to start with the iron-making technology.

Pig iron is generally unusable after smelting, so it needs to be processed. For example, a hard, brittle pig iron is combined with a soft, tough sticker to create a higher quality steel.

You know, the Chinese are the first people in the world to use cast iron. And heterozygous pig iron wrought iron is also the earliest.

Wang Cang said in "Knife Inscription": "The irrigation folds have been numbered, and the quality has been presented. ”

"Seven Lives": "It is refining and shimmering, and it is a thousand irrigations." ”

Qimu Huaiwen practiced the Su Iron Knife, and his achievements can be described as epoch-making and opened up a new world.

First of all, this is clearly compared to the previous steelmaking method. Let simple cast ironware become backward. Since the Bronze Age, China has seriously lacked forging and heat treatment experience, and cannot directly follow the path of surface carburizing steel like other great civilizations. The steel filling method allowed the Chinese to bypass this difficult road, according to the steel filling method of the later Song Dynasty, forging iron body steel blade agricultural tools was relatively easy, from the Southern and Northern Dynasties, forging iron tools began to gradually replace cast iron tools.

Since then, welding technology has also become widespread, and the production cost of weapons and iron agricultural tools has been lower, and the practical application has been more rapid.

However, with the development of the times. At present, the Ming Dynasty is already the seventeenth century. Thousands of years have passed, and what was once an epoch-making invention is now gradually becoming insufficient.

In the past thousand years, the once ignorant West has quietly begun to catch up, and has gradually surpassed the Eastern civilization.

If Zhu Cihong is still the original Zhu Cihong who has not crossed over, then he naturally will not understand these, even if the iron is worse, it doesn't matter.

But the new Zhu Cihong was born, and the requirements of the Ming army also rose rapidly. The army under firearms has higher requirements for the process of materials, and it is not a harsh reproach to be able to accept one-third of the requirements this time, but it is really an urgent requirement for military supplies, and it has to lower some requirements, so that the ordnance workshop can complete the part of the material process requirements that are not very strict.

But for those materials such as the barrel of the gun and the barrel of the cannon, it is obvious that it cannot be subservient.

Zheng Anchun and Zhan Feiyu obviously don't understand these histories.

For them, why can't what their ancestors invented?

Zheng Anchun probably guessed Fang Yizhi's reliance, that is, the woman in front of him, Tian Yingqi. Obviously, convincing this person will be able to control the steel mill, not this Fang Yizhi who doesn't take a few of their iron-making families in his eyes.

It's just that Fang Yizhi hasn't replied yet, and I don't know when a young man sat between Fang Yizhi and Tian Yingqi.

The young man couldn't help but shake his head and smiled: "If I remember correctly, the steel filling method has been born for thousands of years. This method, thousands of years ago, was indeed a shocking breakthrough for the world, and it was a centuries-old breakthrough. But after a hundred generations, the descendants still keep this secret skill, which is a bit too regrettable. Since the reason for the Privy Council's refusal is not to ask for bribes and deliberately block people, but really because of the quality of the product, then the technique should be improved, and not indulged in the glory of the past. ”

"Who are you? I'm waiting here to discuss the method of ironmaking, and you actually ran out? Zheng Anchun was annoyed.

"I, I just know a little bit about it, so I can't help but interject." Zhu Cihong smiled with a smile.

Facing Zhu Cihong's smile, Zheng Anchun felt extremely embarrassed and annoyed: "Dare to talk nonsense if you know a little bit or two?" Then I will ask you: What does it say afterwards that he bends it with soft iron and traps it in the midst of it with pig iron? What does that mean? ”

Zheng Anchun said a word, but he was a little tricky.

"How don't you know?" Zhu Cihong replied without thinking about it: "This is the Song people's method of steelmaking. The wrought iron is forged into thin strips, then coiled into a ball, and then the pieces of pig iron are placed on top of the wrought iron dough. There is even a better way to roll wrought iron bars into spirals and stuff pieces of pig iron into the spaces between the spirals. Then seal the stove with mud. As for you, it should be to seal the iron mass itself, and then start burning and heating until the temperature is extremely high and the pig iron melts. Due to the mud sealing, the pig iron will not be decarburized due to oxidation, but will become molten iron and flow into the wrought iron. ”

"Well, am I right?" Zhu Cihong chuckled.

On the side, Fang Yizhi couldn't help but applaud.

This slap in the face is a bit harsh.

Zheng Anchun was also stunned, he didn't expect this newcomer to jump out inexplicably so expected.

Before Zheng Anchun could speak, Fang Yizhi couldn't help but make a slap: "That's right, this is what Shen Kuo of the Song Dynasty said." I didn't expect this brother to have such a good memory, and he has this wonderful method. And...... It can also reveal the secret skills of the steel plant. ”

At this time, Zhan Feiyu on the side stepped forward and said, "Since this brother knows about it, why do you still say that it is wrong for us to wait for the iron-making method?" This is the secret of many iron-making people! ”

"The so-called secret that is not passed on, but to put it bluntly, it is very simple." Zhu Cihong said again: "Moreover, it also shows that tricks are not done by wise men." This may seem like a subtle approach, but there are two problems. First, the molten iron itself is not a good carburizing agent. With the exception of China's steel filling and the diffusion method that Xiyi briefly tried, no one uses this method anymore. Molten iron is a viscous liquid, which makes more carbon and other impurities remain in it, but when the steel is filled, the iron mass has been sealed with mud, and there is less oxidation, and the impurities will spread out less. ”

Tian Yingqi was a little dizzy, but he couldn't help but have starry eyes in his eyes.

On the other side, Fang Yizhi quickly picked up a small notebook and remembered these unfamiliar terms.

"To put it simply, molten iron melts and seeps into wrought iron, making it carburized, as if you sprinkled white sugar on top of white rice and then put it in a pot to steam, hoping that it will become as sweet from the inside out. In most cases, only the carbon can penetrate into the shallow part of the wrought iron, and the cooled molten iron becomes the high-carbon part of the steel. In other words, the characteristic of steel filling is that the carbon content is uneven. As for the other point, I'm afraid it's a bit complicated...... Of course, it's a bit easier to put it bluntly. Zhu Cihong paused and thought about the wording.

Now, everyone is more curious.

Even Zheng Anchun was also suppressed at the moment.

He wanted to refute it, but many of the nouns Zhu Cihong said seemed to him to understand. This state of seeming to understand but not understanding doesn't make him want to be responsible for Zhu Cihong's blind fabrication, but as a technician of iron-making for generations, he just thought about it slightly, and he couldn't help but marvel at the subtlety of the meaning hidden in these words.

In this way, he didn't dare to refute rashly, for fear of being slapped in the face again.

At this time, Zhu Cihong had already thought of the wording, and only listened to him: "It's like, why is everyone in this world standing on the ground and not flying out?" Why do apples fall from trees? There is a power in all this. It's gravity from the earth. Therefore, what we are talking about is the problem of gravity. When the molten iron melts, it flows downward, and when cooled, the lower part of the billet has a higher carbon content and the upper part has a lower carbon content – still an uneven carbon content. ”

Speaking of which, Zheng Anchun and Zhan Feiyu no longer intend to object. As far as technical matters are concerned, this one is a real connoisseur.

They all turned their gazes to Sun Tiedong on the other side. This one, but the technology of the entire Jingshi Iron and Steel Plant has been mastered.

Sun Tiedong didn't know when he didn't sleep anymore, he listened with blazing eyes, and there was a scholar beside him who was constantly anxious about what Zhu Cihong had just said. (To be continued.) )
