Chen Wanrong picked up the charcoal on the table and drew it, and drew a vertical stove in just a few strokes. Chen Wanrong interned in a famous steel company in China during his university years. He had some understanding of modern blast furnace iron smelting, and the stove drawn according to his memory seemed to look like it.

Those who study chemical engineering know that chemical engineering is not only able to shake test tubes, do tests, observe chemical reactions, but also materials science. Materials science is very important for the chemical industry. Most of the reagents in the laboratory are bottled in glass. Why should be bottled in plastic? Because alkali needs to react chemically with glass and not react with plastic.

This is the importance of materials learning. If you don’t have the knowledge of materials learning, using glass bottles to fill alkali will make a big joke. The chemical engineering school with conditions will arrange as many students to intern in factories in different industries as possible to increase their knowledge. The school Chen Wanrong attended is a school with extensive connections with all walks of life. Chen Wanrong has interned in several industries.

The Tang Dynasty used the "steel filling method" to make steel. The so-called steel filling method was to heat pig iron and cook iron together, use the principle of low melting point of pig iron to melt it, pour it into the voids of cook iron, and achieve the purpose of carburizing. Pig iron has a high carbon content, while cook iron has a low carbon content and is softer, so that the two can obtain steel once they are fused.

Before the invention of the steel filling method, steel was mainly obtained by forging pig iron. The "several tempering" and "thousand tempering" in our vocabulary were obtained from this. This method is labor-consuming and time-consuming and has a small output, which restricts the development of productivity.

Tao Hongjing during the Southern and Northern Dynasties made significant contributions to the invention of the steel filling method. It was precisely because of the birth of the steel filling method that the steel production in ancient China surged and the quality was greatly improved. Therefore, the armor-mounted rate of the Tang Dynasty army was very high, as high as 60%, which was the highest armor-mounted rate of the ancient Chinese army.

A Modao requires fifty kilograms of high-quality steel. The Modao can become one of the main combat weapons of the Tang Dynasty's army. The reason is not only because the Tang Dynasty's strong national strength, but also because it uses a new production technology such as the steel filling method to produce sufficiently used good steel.

Zhang Deming had never seen a modern blast furnace before, so he couldn't see it clearly, so he touched his forehead and asked with confusion: "Wanrong, what are you painting? I looked like a melon, which is a melon that stands up. This melon is quite strange. It doesn't have any stalks, and there are no vines. How did this melon grow?"

Chen Zairong, who had always been smart, was confused. He blinked his bright eyes and asked in confusion: "Brother, what are you painting melons?"

In terms of appearance, it is not necessarily wrong to regard the blast furnace as a standing melon. Although this metaphor is vivid, it is a bit funny. Chen Wanrong held back his laughter and explained to them: "This is not a melon, this is a stove, which can be used to make high-quality steel."

Zhang Deming leaned forward suddenly, his forehead almost hit Chen Wanrong's head, and asked anxiously: "Stove? What stove? Can you really make steel?"

The utensil used in the steel filling method is called a cauldron, not a furnace. Therefore, when Zhang Deming heard the word "furnace", he became curious and a series of problems were thrown out.

"Fill iron ore, coke and limestone in the furnace, and after heating, we get molten iron. After cooling the molten iron, we can get steel. Fill iron ore from the top and release molten iron from the bottom outlet. Without stopping, we can produce continuously." Chen Wanrong explained the advantages of modern blast furnace iron smelting based on his memory.

The use of limestone to smelte iron is to reduce the melting point of iron. This method has been used since the Western Han Dynasty and is still in use until now. This is a great initiative of our ancestors.

Zhang Deming shook his head violently, looking disbelief: "Iron? What's the use? Iron is waste, it's okay to cast pig iron, but it's not good for steel making, it's useless, useless! If you want good steel, you have to rely on this." Pointing to the hammer on the ground, it means that it's still necessary to forge it.

It is precisely because the top-quality steel in the Tang Dynasty was forged with hammer and hammer that it was impossible to make plates. Without plate chemical equipment, it would not be made. Today, I have to open your eyes. Chen Wanrong is determined to teach Zhang Deming a good lesson.

The Tang Dynasty obtained block steelmaking, and it had to be forged to obtain high-quality steel. I only used molten iron for pig iron. Zhang Deming believed that it was not ordinary and difficult to obtain steel from molten iron.

"I would rather believe that gold ingots fell from the sky than that of iron and steel." Zhang Deming looked at it disdainfully, and his head shook like a rattle, as if he had seen the most ridiculous thing in the world.

This was too straightforward, and Chen Wanrong was choking for a moment, and Chen Zairong hurriedly made a smoother: "Master Zhang, please let me finish my words. My brother may do it, and his words must make sense."

"Brothers fight against the wall and defend against their insults." Brothers are brothers, always facing themselves. Chen Zairong's words are full of praise. Hearing Chen Wanrong's heart aroused warmth. It's really lucky to have such a clever brother.

Zhang Deming looked at Chen Wanrong and saw that Chen Wanrong was shrewd and confident, not as if he was talking nonsense, but he was determined to listen to the idea of ​​talking again and stopped talking.

Chen Wanrong knew his thoughts. In order to strengthen his confidence, Chen Wanrong did not directly explain the art of steelmaking, but explained the scientific research principles: "Master Zhang, you also know that the waste now may not be useless in the future. Turning waste into treasure not everything can succeed, it is not that there is no one. Paper cannot be copied at the beginning, but can only be used for decoration. After Cai Lun's improvement, hasn't it been popularized in the world?

"By the same reason, molten steel cannot be made now, and it is unknown that the steel in the future comes from molten steel. Technology is a thoughtful job. There are many things that need to be proved by yourself. You cannot just listen to other people's preaching. Only in this way can you have your own experience, experience, and understanding more deeply.

"My respectful teacher, Master Ye, can improve the Modao to be more suitable for use on the battlefield. I believe Master Ye must have used it personally, experienced the life-and-death battle on the battlefield, and know what kind of weapons are needed on the battlefield.

"Only in this way can we be better than the best, new technologies will be invented, and new things will appear."

Chen Wanrong is a technical person and has a very good understanding of technical matters. This is an experience. If a person who works in technology, friends who do scientific research will agree.

Although Zhang Deming is a country blacksmith, he has his own uniqueness when he can join a master like Ye Tianheng. He is very impressed by this. He knocked his right hand heavily on the table and exclaimed loudly: "Wanrong, your words have won my heart and my heart! Wanrong, I'm sorry, I just said something wrong! Please teach me how to get steel."

This is said very sincerely and has a respectful attitude. Even when facing Master Ye, this is the case. Chen Wanrong admires his desire for learning and thinks that his sincere attitude of learning is enough to move people. It is reasonable for Master Ye to accept him as his disciple. He smiled and said, "Master Zhang is so serious, I am not knowledgeable and dare not teach. I just have a little opinion for your reference."

As Chen Wanrong thought, Zhang Deming took Ye Tianheng as his teacher, and there were other twists and turns. Ye Tianheng was a master of the military weapon supervisor. He had a high vision and did not accept disciples easily, nor would he accept Zhang Deming, a country blacksmith. However, Zhang Deming had a sincere heart. He knelt outside the Ye Mansion for a day and a night, which moved Ye Tianheng and happily accepted him as his disciple.

Chen Wanrong based on his memory, he told him that some modern steelmaking methods were very tempting to explain the processes one by one.

As soon as he finished speaking, Chen Wanrong's throat was dry and he turned his head to drink water, but he could not see the tea tank sitting on the water. He saw Zhang Deming standing like a statue of Zun, his mouth was wide open, and his saliva flowed down the corners of his mouth, dripping onto the table, wet the boss.

"It's over? Is it over?" Zhang Deming was stunned for a while, wiped the saliva from the corner of his mouth, and suddenly asked this question.

The Tang Dynasty was a magnificent dynasty, which was fascinating, but its technological level could not be compared with modern times. Even if Zhang Deming knew modern steelmaking technology, it would not be possible to make steel like modern times. However, modern steelmaking technology would definitely have an enlightening effect on them. With the supreme wisdom of our ancestors, some unexpected changes might occur.

This change is exactly what Chen Wanrong expects. Improving the quality of the Tang Dynasty's steel is not only beneficial to the Tang Dynasty, but also to himself. Hello, I, everyone's good things. Chen Wanrong did not hide his own personal information at all, and told everything he knew.

Chen Wanrong could only say that he had some understanding of steelmaking, let alone proficient, but this still made Zhang Deming fascinated. Until he finished speaking, he was still unsatisfied and asked in this way.

Chen Zairong didn't know much about technology. Based on his intelligence, he knew that Chen Wanrong was talking about another new world. He summed it up with his unique vision: "What Brother said can become a reality, our current steel does not need to be forged with one hammer. What does it mean? It means that we have as many weapons as we have. It's okay to wrap our army with steel in one layer. Oh my God!"

There is no need to learn all modern steelmaking technology. Just learn coking and use it well, which is enough to trigger a revolution, and the quality of steel will undergo tremendous changes. Zhang Deming is indeed unique in technology. When he recalls it, he immediately asked: "Wanrong, is the coal you mentioned black stone?"

Without waiting for Chen Wanrong to confirm, he quickly entered the inner room. When he came out, he had a black stone with metallic luster in his hand. He pointed to the black stone and said, "This black stone can be burned, and it is more effective than a piece of charcoal. The villagers use it to cook. There is this thing on the mountain west of our Luojiadian. Last time I visited relatives, I took one by the way."
