Rebirth 76: Industrial Internet Empire

Ren Jie looked sad and sighed: "The old man refused to say his name. What he has learned in his life is of no use. He is ashamed of his mentor and ancestors, so it's okay not to mention his name! The old man was also caught in a flash flood. Unfortunately, he died and those notes were not preserved!"

Zhou Xiaohan's mood instantly fell to the bottom, and the hope he had just ignited was ruthlessly extinguished...

Ren Jie continued with a solemn expression: "If the old man has a soul in heaven, he will definitely find it difficult to let go. By chance, although the old man taught him all he has learned in his life, the students are naturally stupid, and they just barely entered the classroom and failed to understand it. I feel ashamed." Great love for his old man!"

Hope rekindled in Zhou Xiaohan's eyes, and he asked hopefully: "Did the old gentleman tell you specifically about the experimental data and various index parameters of the carburizing process?"

Ren Jie nodded, with a fascinated expression on his face, and sighed leisurely: "Fate has its way with people, and God is jealous of geniuses! The old man is simply a genius in metallurgical heat treatment. Many of the ideas he proposed are far beyond this era. Regarding osmosis, Regarding the carbon process, he recorded some test data. The best laboratory data has ever been reached: surface layer hardness hrc53~58, core hrc38~45..."

There was a strange look in Zhou Xiaohan's eyes. Isn't this the technical indicator parameter he dreamed of?No, he didn't even dare to think of such parameters, such hardness and toughness, not to mention the gearboxes of self-propelled artillery and load trucks, the gearboxes of civilian gas turbines are also enough!

Thinking of this, the middle-aged Zhou Xiaohan felt panicked for no reason. This is a common problem for technical geeks like him. They have no desires and desires. Only technological breakthroughs can make them ecstatic...

Zhou Xiaohan asked with some uneasiness: "I wonder if it's convenient, little brother? Come to the technical department of our machinery factory and sit for a while. You guessed it right, we did encounter some technical bottlenecks..."

Ren Jie deliberately looked back at the remaining vegetables on the tractor, nodded and said, "Mr. Zhou, do you think this is okay? The remaining vegetables we have can probably be sold in an evening market. After buying them, we will simply After dinner, I’ll go to the machine shop to meet you, what do you think?”

Zhou Xiaohan pondered for a moment, then turned to tell Zhou Ying: "Go to the factory office to find Director Ye and ask someone from the logistics department to bring these dishes to the canteen."

Zhou Ying turned around and ran away, but Ren Jie followed the snake and asked half-jokingly: "Is Mr. Zhou planning to underwrite all the food of our Xiaping brigade in the future?"

Zhou Xiaohan was a pure technical geek and did not feel that Ren Jie was taking the opportunity to negotiate terms. He said seriously: "These are all trivial matters. The canteen has to purchase anyway. The most important thing right now is to solve the technical bottleneck of the carburizing process." !”

However, Ren Jie knew that for such a large-scale state-owned factory, there was a chain of interests in the procurement of various materials. Although Zhou Xiaohan was the chief engineer, he was only responsible for technical matters and was most likely unaware of these interests. To be on the safe side, You still have to go to the factory office to talk.

In this era, the procurement of non-staple food from large state-owned factories is still limited supply, and the planned supply cannot meet the demand at all, so an unplanned industrial chain has been derived. The non-staple food company goes to the Chengguan Vegetable Brigade to purchase various non-staple food to meet the unplanned supply. The black market price is sold to large state-owned manufacturers in need. There are two sets of price systems, and the price difference is redistributed among relevant stakeholders. However, in this era, there is not much appetite. As long as you know how to behave, everyone will turn a blind eye...

Of course, Ren Jie is not stupid enough to negotiate any conditions with the factory management now. The most taboo thing is to put forward various conditions without doing anything.

Ma Xiaojun and others stayed to weigh in with the people sent by the logistics department, while Ren Jie followed Zhou Xiaohan straight to the finishing workshop.

Walking into the workshop door, a group of people were talking around a box of returned gears. Ren Jie stepped forward and squatted down to pick up a few gears. These returned defective products had either broken teeth or peeling gear surfaces. He wanted to Taking into account the tooth body toughness and tooth tip hardness, the final result is that both technical parameters fail to meet the standards.

In his previous life, Ren Jie was either in a laboratory or in a workshop, dealing with master workers. He knew very well the nature of these masters. Everyone depends on their ability. If you have the ability, they will obey you. If you scold them, they will sound friendly. If you have no ability, they will be rude. No matter how polite you are, no one will criticize you.

Ren Jie was not polite and directly gave the order: "Re-turn a few workpieces for spare use, and use 35# steel instead!"

A young worker retorted loudly: "Did you make a mistake! The 45# steel has contact surface wear and pitting corrosion, so why not use 35# steel? This is a load-bearing gear!"

Picking up the workpiece in his hand, Ren Jie suddenly showed a different temperament and said without any doubt: "First of all, we must solve the problem of broken teeth. Whether it is used on a heavy-duty truck or a large mechanical chassis, broken teeth are the most serious problem. Yes, the yield rate of broken teeth is the top priority!”

Zhou Xiaohan said in a deep voice: "Ye Ming, why don't you go quickly?"

Everyone began to look at this young man again. His young face looked like he could be in his early twenties, but there was an extraordinary momentum!

Ren Jie was not idle either. He was skillfully installing card slots and turning tools according to the drawings. Qin Dashan, the workshop director who had been standing beside him without saying a word, suddenly narrowed his eyes. Anyone who knew him well knew that he was only surprised. Or you will have this expression when you are angry.

This is a gear hobbing machine produced in Eastern Europe in the 50s. The accuracy is not very high. Old workers who are familiar with this machine know that you need to leave a little margin when roughing, otherwise the error will cause the workpiece to be scrapped. Ren Jie just debugged the hobbing machine When he installed the card slot, he readjusted it again. He was obviously familiar with this defect. Qin Dashan's face also became solemn. Although this gear hobbing machine is old, in this era when many machinery factories still use milling machines to process gears, it is already It's a rare object, but this young man can actually use it skillfully. Even he can't understand this young man...

After a while, Ye Ming brought 35# steel from the warehouse. Two master workers took it and quickly processed the blank into gear workpieces. Ren Jie carefully measured it with a caliper, and then placed it on the debugged gear hobbing machine. After a while, the first rough-machined gear comes off the production line.

After Qin Dashan personally picked up the caliper to measure, his face showed a look of satisfaction. Ren Jie had won the recognition and respect of him, an old worker!

Ren Jie continued to issue a set of instructions: critical temperature quenching. After quenching, use normalizing to refine the grains, adjust the hardness and complete the fine machining of the tooth tips.Reheat to 30 degrees above the critical temperature and cool in air.

At this time, the factory office ordered the canteen to deliver lunch to the workshop. Everyone was anxiously waiting for the workpiece to cool down naturally. Only Ren Jie found a shady place and fell asleep after eating...

Zhou Xiaohan, Qin Dashan and others gathered around the air-cooled workpiece, watching quietly as the gear slowly returned to normal temperature and began to emit blue light. This green light, which is intertwined with ferrite and pearlite, appeared in the air-cooled workpiece. In the eyes of these metallurgical robots, they are probably the most beautiful colors in the world, exuding industrial beauty!
