Zhou Kai was like a miscellaneous man, helping to hand over tools on the side. Because the difficulty factor was too high, and he had never set foot in such a profound technique, he was confused.

As for Niu Xiaoqiang, he has been immersed in the engine for many years with Fang Dongping, whether it is the theoretical level or the actual machining technology, he is far beyond the average technician, not to mention one person under ten thousand people in China, it is also the elite of the elite.

At this moment, with Fang Dongping's teaching, Niu Xiaoqiang naturally learned faster, and in less than two hours, he offered to make his own sand mold of the engine cylinder head.

Zhou Kai was dumbfounded again, and his heart was shocked: just an hour ago, Niu Xiaoqiang, like himself, didn't know anything about hand-casting sand molds, but just an hour later, this guy proposed to do it alone, is this kid still a human? It's too perverted! It's just a monster! There is also Old Man Fang, he is also a monster, no matter how difficult the technique is, this old man understands everything, and all of them are terrifying! As the saying goes, things gather people in groups, and these two monsters can become masters and apprentices is indeed very appropriate, and if they are replaced by other people, how can they team up with them?

"You can try it, anyway, the material cost is yours, let's do our own thing, if you don't understand anything, just ask me." ”

"Yes, Master. ”

The master and apprentice exchanged a few words, and then they got busy.

Niu Xiaoqiang started from frosting and officially stepped into the stage of hand-casting molds. This is a legendary skill that is not so easy to learn. Although Niu Xiaoqiang is very confident, he does not think that he can learn it immediately. He works very seriously and tries to do the best he can in every link.

After grinding the sand, Niu Xiaoqiang poured the chemical binder into the sand pile and stirred it according to the dosage ratio that Fang Dongping had taught him before. After the chemical binder and the sand grains were evenly mixed together, Niu Xiaoqiang immediately picked up a handmade knife and carved it on the sand ball.

Zhou Kai saw that the master and apprentice were working like embroidery, and couldn't help but feel very bored, so he said hello and went outside to smoke.

Midsummer is very hot, and even after 12 p.m., the temperature is a little high. The workshop was not ventilated, it was very stuffy, and Zhou Kai felt refreshed after coming out. He unbuttoned his shirt and sat on the steps at the door of the workshop, smoked two cigarettes, and got up to check on the situation.

Not long after, Zhou Kai, who felt bored, slipped out to smoke again, and after repeating this four or five times, Zhou Kai couldn't hold it anymore and fell asleep on the steps.

When the sky was dark, Zhou Kai was woken up by Niu Xiaoqiang: "Brother Zhou, don't sleep, let's go back." ”

Zhou Kai sat up in a daze, rubbed his eyes and looked at Niu Xiaoqiang, only to find that Niu Xiaoqiang's hands were empty, and then he looked at Fang Dongping, and he didn't hold anything in his hands.

He was slightly stunned: "Why didn't you bring out the mold you made?"

Niu Xiaoqiang smiled bitterly and shook his head: "Do you think it will be so easy to succeed? This is the first time I have done it manually, and my master has not done this for many years. ”

Zhou Kai couldn't help but breathe a sigh of relief when he heard this, and said in his heart: Fortunately, you didn't succeed, otherwise I would really treat you as monsters, I'll just say, how can there be such a powerful person in the world.

Fang Dongping was originally full of confidence, but he failed to cast it, which made him a little embarrassed. He walked out first, without saying a word.

Niu Xiaoqiang knew Master's thoughts, and he comforted: "Master, you have too high requirements for yourself, and you haven't carried out practical operations for such a long time, so you didn't succeed, as long as you practice a little, I dare to make sure that you will succeed soon, go, the apprentice will take you to eat delicious food, you wait for a while, drink well, let's go back to sleep, and continue tonight." ”

Fang Dongping couldn't help but laugh and said: "How do you feel like you're coaxing a child? Don't worry, Master is not so fragile, if he doesn't work once, twice, twice, three times, there will always be a time to succeed." ”

Niu Xiaoqiang smiled and nodded, under the leadership of Zhou Kai, the three of them came to a breakfast shop next to Yuyang Agricultural Machinery Factory, ate and drank a good meal, and then got up and went back to rest.

In the next half month, Fang Dongping and Niu Xiaoqiang's hand-carving skills became more and more proficient, and with their unremitting efforts, a complete set of molds for engine parts was finally made. The next step is to pour the steel.

Niu Xiaoqiang had already told Fang Dongping the secret of super carbon steel, and Fang Dongping knew the general parameters of super carbon steel.

In order to open up the situation with one shot, Fang Dongping designed the engine with very high specifications, according to his words: "The performance of this engine definitely exceeds all the current domestic products of the same model, as long as it is an engine of this displacement, there is nothing that can be compared with it!"

This is not a big talk, Fang Dongping has this confidence. His confidence comes from the superior performance of super carbon steel.

In fact, there is no shortage of excellent designers in China, what is really lacking is superior performance materials and high-precision processing equipment.

The processing equipment is okay, and if there is no machine, it can be replaced by manual labor. But if the material is not up to par, then everything is in vain. Even if you can design a space battleship, you can't build it at all, so what's the practical point of such a good design?

Super Carbon Steel is ideal for engine building and is arguably the best material tailored for engines.

In addition to the engine, this amazing metal can be used in other ways. However, Niu Xiaoqiang has no plans to promote it at present, he is ready to come step by step, and first do what he can do well. Otherwise, a hammer in the east and a mallet in the west will greatly affect his energy, and then affect his development plan.

Or first put the fist products down, with fist products, in order to have a foothold in the machinery industry capital, at that time, no matter what is more convenient.

Zhou Kai was naturally in charge of steelmaking, and Fang Dongping and Niu Xiaoqiang stood on the sidelines to watch.

Seeing that the temperature of the steelmaking furnace was getting higher and higher, the smile on Fang Dongping's face was getting stronger and stronger: "Xiaoqiang, this material you invented is good, you must keep the secret of this material well, and don't be stolen by others, otherwise the loss will be too great." ”

Niu Xiaoqiang had thought so for a long time, and did so: "Master, rest assured, the production technology of super carbon steel is currently known only to me in the world, and I am ready to regard it as the foundation for us to step into the machinery manufacturing industry, and it will not be obtained by others anyway." ”
