Manufacturing Empire in the Valley

Chapter 96 Materials Science
Under the leadership of Master Shen, Niu Xiaoqiang and Fang Dongping boarded the operating platform.The ingredients have been prepared on the platform. Fang Dongping first looked at the ingredients, but he didn't see any problems, and then he turned his attention to the furnace.

Niu Xiaoqiang was also watching from the sidelines. The furnace wall was covered with high-temperature-resistant materials, some parts of which had fallen off, and there were traces of repairs on it.

Fang Dongping quickly pointed to a repaired place and said, "Master Shen, the high-temperature-resistant material in this place is not tight enough, there are gaps, and there are still carbon residues in the gaps, can you clean it up?"

In the past, Master Shen was too lazy to do anything in such a situation. In his opinion, such a small amount of carbon slag would not affect the quality of molten steel at all.But he was lectured by Fang Dongping just now, and his attitude has improved a lot, so he nodded: "No problem, I'll clean it up right away."

The two apprentices also helped, and it took the three of them more than ten minutes to clean up all the carbon residue.During this period, Fang Dongping explained to Niu Xiaoqiang another important field of industrial manufacturing, which is material science.

He first took Niu Xiaoqiang to familiarize himself with the preparation of materials, and then explained: "Xiaoqiang, in addition to mastering high-end processing technology, there is another very key point in industrial manufacturing, that is, material science. The quality of materials is directly related to the quality of products. Service life and quality must be paid attention to. Do you know why I urge you to learn physics and chemistry well? It is because these two subjects are closely related to material science. If you do not lay a good foundation, you will be a senior technician and product at most in the future It’s nothing more than a researcher, it’s quite difficult to make a truly high-end product.”

Niu Xiaoqiang snorted: "No wonder you always forced me to memorize the periodic table of elements and memorize various chemical reaction formulas before, so it was because of this."

Fang Dongping nodded with a serious expression on his face: "Although you don't have the conditions to conduct scientific experiments yet, you can set up a laboratory after you earn money in the future. If you can make a difference in material science, then you You can definitely achieve a height that others cannot reach. In a very vulgar word, you can earn 1 yuan, but if you rely on material science, you can easily earn 10 yuan. Qian, this is a superimposed effect of one plus one greater than two, do you understand?"

Originally, Niu Xiaoqiang was only interested in manufacturing technology, but he couldn't help being taken aback when he heard this: "Master, is it really as mysterious as you say?"

Fang Dongping saw that the economic stimulus policy had an effect, and immediately added fuel to the fire: "Of course, you should not underestimate the importance of materials. Take diesel engines as an example, the materials used have been tested many times. It has only been finalized, and many manufacturers regard the formula and production process of the material as the treasure of the factory, and never disclose it to the outside world, and we can see one or two from this.”

Niu Xiaoqiang originally thought that domestic manufacturers used the same materials to manufacture engines, but when he heard Fang Dongping say that each factory had its own special formula, he was taken aback for a moment, and then he was relieved.

In fact, this is also easy to understand: everyone wants to eat, and they are competing with each other. The market is so big. If you eat too much, I will not be full. In order to be full and eat well, Whether it is technology or material formula, of course it must be kept secret.

At present, local protectionism is prevalent in various provinces and cities in China. In order to protect local enterprises, some local governments even use administrative means to forcibly intervene.Niu Xiaoqiang has read a lot of extracurricular books, so he knows something about it.

Fang Dongping continued: "Last time Master talked to you about the technological gap between our country and the Soviet Union. I said at the time that the gap was at least 30 years. This is due to the fact that material science is too backward. For example, aeroengines, we It’s not that the country cannot design better products, it’s just that the foundation of material science is too weak, so even if there are design drawings, products cannot be produced, which shows how important material science is.”

Niu Xiaoqiang nodded again and again: "I understand, after I learn the manufacturing technology, I will definitely study material science painstakingly."

"Fang Gong, we have cleaned up the carbon residue, would you like to check it?"

Fang Dongping turned his head to look, then smiled and said, "As expected of a master, the work is really beautiful."

Master Shen who received the praise immediately showed a smile, as bright as the primary school students who received the certificate.

In order to let Niu Xiaoqiang have a more comprehensive understanding of material science, Fang Dongping took the initiative to chat with Master Shen about the steelmaking process and precautions.It involves the adjustment and control of temperature, the delivery time of various ingredients, the correct use of various catalysts, and so on.

These originally belonged to the category of confidentiality, but there was no need to do so with Fang Dongping, because he himself was a big expert in this field.

Niu Xiaoqiang became more and more fascinated the more he listened, and at the same time he had a deep understanding of the complexity of material science.He secretly counted and found that the seemingly simple steelmaking needs to go through more than a dozen processes.These procedures are very strict, and no mistakes are allowed, otherwise unqualified molten steel will be produced.He couldn't help secretly marveling: I really admire those predecessors, how did they invent such a complicated material processing technology?How many trials does this need to do to succeed?

Fang Dongping knew what Niu Xiaoqiang was thinking when he saw Niu Xiaoqiang's expression, he pulled Niu Xiaoqiang aside, "Do you think this is over?"

Niu Xiaoqiang's eyes widened: "Isn't that enough?"

Fang Dongping chuckled: "Of course it's not enough. After the molten steel comes out of the furnace, it needs to be poured. During this process, the cooling process needs to be strictly controlled. If there is a problem with the cooling process, it will be discarded together with the sand mold."

Niu Xiaoqiang sighed: "Master, why do I feel that material science is much more difficult than operating machine tools?"

"It's true. Various materials are mixed together. The dosage of each is different, and the time for chemical reactions is also different. It can be said that it is a combination of many different combinations. Since this field is relatively complicated, I am worried about you. You will be distracted, so I didn’t mention it to you before, with your super fast learning speed, I think you can already learn theoretical knowledge in this area, so I mentioned this subject to you.”

Niu Xiaoqiang just sighed just now, not because he was afraid of this subject. Hearing this, he immediately asked: "Master, it seems that you don't have any books on material science at home? How can I learn it?"

Fang Dongping looked at Han Shuren, who was walking quickly: "It's simple, just ask Director Han to sponsor him. He has a double doctorate in physics, mechanics and chemistry. There must be many books of this kind at home."
