Rebirth 76: Industrial Internet Empire

The needle drop could still be heard in the conference room, and only coughs choked by smoke could be heard from time to time. Zhou Xiaohan said solemnly: "If these gears cannot be delivered on time, all bonuses for this year will be cancelled, starting with me in the technical department!"

A middle-aged man wearing glasses muttered: "You can't blame us. There are CNC gear hobbing machines abroad. It is said that there are more advanced gear grinding machines. We still use the old gear hobbing machines that were eliminated by the Soviet Union in the 50s. This section Over time, the cutting blades of gear hobbing machines have been used up a lot, and the hardness has increased, but the toughness of the tooth tips still does not meet the requirements. I think the root cause is the Southwest Special Steel Factory. They cannot provide steel with hardness, toughness and strength that meet the requirements of gear technology. The key is, if the steel does not meet the design requirements, how can we forge a workpiece that meets the requirements?"

Zhou Xiaohan was unable to refute, and sighed and said: "Lao Su, there must be difficulties. Southwest Special Steel Plant has also responded. With the current domestic smelting level, it can only reach such technical standards. Let's work together and try Think of another way in terms of heat treatment and finishing?”

After a while of whispering, the small conference room was silent for a long time. Zhou Ying, who had been silent all the time, suddenly said: "I met a strange young man at Xinhua Bookstore today. He saw me working on the reheating and finishing work. Information, suddenly asked, is it a problem that the hardness of the tooth tip and the toughness of the tooth body are incompatible? I was wondering how he knew, and before leaving, he said six more words, which I thought made sense, and seemed to be true. There is hope to solve this problem!”

Everyone asked in unison: "What six words?" In fact, they didn't really believe that the young girl Zhou Ying could come up with any earth-shattering solution, just like a drowning person grabbing the only life-saving straw.

Zhou Ying stopped being pretentious and said softly: "Try the carburizing process."

The conference room fell into deathly silence again, and only the ticking sound of the hour hand on the wall clock could be heard. After a while, Zhou Xiaohan suddenly revealed his eyes and asked in a deep voice: "Can you still find that young man?"

Zhou Ying shook her head, and suddenly remembered what Lu Xiyao said, and blurted out: "Xiao Lu said that he saw him setting up a stall at the gate of the family compound. He seemed to be an educated youth."

The carburizing process is easy to say but difficult to do. The rough-machined workpiece needs to be infiltrated with trace carbon elements into the tooth tip through an air-cooling heat treatment process at a suitable temperature to increase the hardness of the tooth tip, and then finely processed. Processing, which can not only ensure the toughness of the gear, but also improve the hardness of the tooth tip.

For China's first generation of metallurgical robots, which are blocked by Western technology, this proposal is tantamount to gently opening a door. The logic is clear, but with the specific data of the heat treatment of the carburizing process, for the technical staff of Jiangcheng Machinery Factory For example, thousands of experiments are needed to obtain the final data. They cannot afford just the special steel used in heat treatment tests.

This is an independent nation that does not want to rely on others. It must endure the pain on the road to rise. The unknown hardships and sorrows have been like a huge stone for decades, blocking the hearts of generations of industrial people. But the game between great powers Never believe in tears. Not only will no one sympathize with you, but what makes them even more uncomfortable is the gloating and cynicism of their own people!

Zhou Xiaohan was a college student who studied in the Soviet Union in the 50s. He feels the same way as anyone here. He knows better that if they can get the rough heat treatment data of the carburizing process, even if it is just a correct directional suggestion, the technical capabilities of their Jiangcheng Machinery Factory will be directly improved. Going up a level and fully mastering the carburizing process, they will not only have the technical ability to produce high-strength, high-load gears, but the problem of bearing balls will also be easily solved. Gearboxes, one of the three major parts of automobiles, require extremely high gear accuracy. , will be a no-brainer...

Zhou Xiaohan hurriedly ended the meeting and took Zhou Ying to the family home. After walking out of the factory gate, Zhou Ying looked at her father with a solemn face and couldn't help but feel uneasy. She said cautiously: "Dad, you can't do this either. He had too much hope, maybe he was just a blind cat who met a dead mouse. He listened to some technician's chat and knew about such a technical problem..."

Zhou Xiaohan still said nothing. Only a few key leaders in the factory knew that this gear order was for parts made for the 521 Factory. The load-bearing and failure rate requirements under extreme conditions were extremely high, far exceeding Jiangcheng Machinery Factory. technical capabilities.

The failure rate of the first batch of gears produced was extremely high. Because of this, some of the bosses got angry at the equipment meeting. If the gears failed at a critical moment, people would die...

Deputy Director He of the Machinery Department, who was attending the equipment meeting, made a phone call as soon as he walked out of the conference room and scolded Zhou Xiaohan. He then gave the machine factory director Ye Anbang and chief engineer Zhou Xiaohan a fatal task because they could not produce products in line with the technology as scheduled. To meet the demand for gears, Jiangcheng Machinery Factory will stop all R&D funds next year, halve the raw material quota, and cancel all bonuses from the production team leader to the factory director!

Although he was just speaking out of anger, the importance of this task can be heard both in and out of his words. If it is not completed, no one will get any good results!

Walking to the gate of the family home, Zhou Ying recognized Ren Jie at a glance. Although it was just a one-time encounter, the confidence and freedom exuded by Ren Jie were different from all the boys she had ever seen.

Zhou Ying walked quickly to Ren Jie and introduced herself: "Hello, we just met at Xinhua Bookstore. This is our factory's Chief Engineer Zhou. Chief Engineer Zhou is very interested in the carburizing process you mentioned. I would like to discuss some issues with you, is it convenient for you?"

Ren Jie stretched out his hand, shook hands with Zhou Ying and his daughter respectively, and then said with a gentle smile: "It seems that Mr. Zhou has found a way to solve the problem?"

Zhou Xiaohan smiled bitterly and said: "How can it be so easy to find a way to solve the problem? Inspired by you, I have some ideas to solve the problem. The specific heat treatment operation is not supported by experimental data, and there is still a long way to go. I take the liberty Let me ask you, did you learn it at home or at school? Which teacher did you learn from?"

Ren Jie had already thought of an excuse: "My name is Ren Jie. I am an educated youth from Yanjing in the Xiaping Brigade of Bei'an Commune in Annan County. I like to read some books on metallurgical machinery before jumping in the queue. When I jumped in the queue, I accidentally met a man who lived in the cowshed. Old man, he taught me a lot of knowledge about metallurgy, and also showed me more than a dozen of his notebooks, which were his life's work and contained a lot of experimental data."

Ma Xiaojun and the others were stunned when they heard this. This girl is so good at boasting. Zhou Ying and his daughter were even more fascinated by what they heard. Zhou Xiaohan asked eagerly: "What is the name of that old man? Where is he now?"
