"Why is it not possible?" Xiao Guoneng shouted anxiously.

"yes, why not?"

Huang Yaohui was also so anxious that he stomped his feet and asked Zhai Yuqiang:

"Lao Zhai, you are the chief of the biotechnology section of our factory, and you have observed the process of Xiao Guo's cold heading process to manufacture special slender bolts, and also got the cold heading mold drawings of special slender bolts designed by Xiao Guo.

"Director Xiao, Director Huang,"

Zhai Yuqiang sighed and said: "The key to the problem is not the cold heading die and the entire cold heading process, but the key is the treatment of high-grade chromium-molybdenum nitriding alloy steel bars before cold heading. ”

Speaking of this, he turned his head to look at Luo Daojun,

"Director Luo, the process of using the turning process to process special slender bolts currently used in the factory is what I did. However, before deciding to use the turning process to produce special slender bolts, I also tried to see if I could use the hot heading process and cold heading process to machine special slender bolts.

"The result of the test is that although the hot heading process can be processed to meet the quality requirements of special slender bolts, but the production cost is almost the same as the cost of using the turning process to process special slender bolts, and the equipment in the factory needs to be updated on a large scale, and the cost is extremely uneconomical.

The special slender bolts processed by the cold heading process are not only prone to fracture in the process of cold heading, resulting in a high scrap rate, but also the tensile strength of the processed finished product is also very low, which cannot meet the requirements of the design.

"So in the end, after careful consideration, we finally decided to start the turning process to process special slender bolts."

"Lao Zhai,"

Although Xiao Guoneng is the deputy director in charge of production, but in terms of specific technology, he is only a little stronger than Huang Yaohui, at this time, listening to Zhai Yuqiang say this, he vaguely remembered that Zhai Yuqiang seemed to have made a relevant report to him nine years ago, so he said:

"Since you said that the cold heading process is used to process special slender bolts, and the finished product does not meet the requirements, then why can Xiao Guo use the cold heading process to process special slender bolts?"

"Director Xiao, just like I just said,"

Zhai Yuqiang replied: "The key to the problem is not the cold heading die and the whole cold heading process, but the key is the treatment of high-grade chromium-molybdenum nitride alloy steel bars before cold heading. ”

"For the treatment of high-grade chromium-molybdenum nitride alloy steel bars?"

Xiao Guoneng is not completely technical white neck, he frowned and said: "You mean to say that Xiao Guo has adopted a certain process and carried out special treatment for high-grade chromium-molybdenum nitride alloy steel bars, so he can use the cold heading process to process special slender bolts that meet the requirements?" ”

"yes, that's what it means."

Zhai Yuqiang nodded and said:

"Generally speaking, the cold heading process to process metal parts requires the raw materials to be phosphated before processing, and then lubricants are added during processing to ensure the finished product rate and product quality of the processing.

"However, the material properties of high-grade chromium-molybdenum nitride alloy steel bar are relatively special, I have tried a variety of formulas of phosphating solution and lubricant, but can not improve the material properties of high-grade chromium-molybdenum nitride alloy steel bar, resulting in a high rejection rate in the processing process, and the quality of the finished product does not meet the design requirements.

The reason why Xiao Guo was able to use the cold heading process to process qualified special slender bolts is that he used a special ratio of composite phosphate solution and a special ratio of lubricant to pretreat the high-grade chromium-molybdenum nitride alloy steel bar, thereby changing the material properties of the high-grade chromium-molybdenum nitride alloy steel bar.

"As long as we don't master the special formula of the two composite phosphating fluids and lubricants in Xiao Guo's hands, it will never be possible to use the cold heading process to process qualified special slender bolts."

I see!

Luo Daojun suddenly realized that he admired Guo Yonghe even more in his heart.

This young man, who really can't be described as an ordinary genius, is not only able to repair all kinds of advanced machinery and equipment, but also has mastered such advanced special material formulas, no wonder he has the confidence to contract labor service companies to produce special slender bolts!

Xiao Guoneng pondered for a moment and asked:

"Lao Zhai, you have seen the compound phosphating liquid and lubricant used by Xiao Guo in the trial production workshop today, right? Do you have a way to analyze the composition of the compound phosphate and lubricant, and then we can prepare it ourselves? ”

"Director Xiao, you really think highly of me!"

Zhai Yuqiang shook his head and said with a wry smile: "Don't say it's me, it's a professor at Zhongtian University who specializes in metal processing, just relying on some finished products of composite phosphating liquid and lubricant, even if it takes four or five years, it may not be able to find the right formula." ”

Xiao Guoneng and Huang Yaohui glanced at each other, and they could see the disappointment in each other's eyes.

"Director,"

Huang Yaohui was still a little unwilling, his eyes rolled for a moment, and he said to Luo Daojun righteously: "Xiao Guo is a cadre of the biotechnology department, so the formula of composite phosphating liquid and lubricant should also belong to the service invention."

"So he should have given both formulas to the factory, not to himself. Wait a minute, can you see if you are doing his ideological work in this area?

"It's a big deal, it's like solving the 75 tractor air filter, reward him with a bonus of 2,000 yuan!"

Luo Daojun coughed, and said to Huang Yaohui:

"Service inventions? Director Huang, this is not reasonable in our factory!

Xiao Guo has been transferred to the biotechnology department for less than three days, and before that, he has been working as a cleaner in the gold processing workshop. Do you think that inventing such a high-end complex phosphating fluid and lubricant is the responsibility of a workshop cleaner? ”

Xiao Guoneng laughed dryly, and defended Huang Guohui: "Factory director, what if these two special formulas were invented by him in less than three days in the biotechnology department?" ”

"Invented in less than three days?"

Luo Daojun couldn't bear it anymore, slapped the table with his hand, and said to Xiao Guoneng:

"Lao Xiao, you have been the deputy director of production for almost ten years, right? Why didn't you invent the formula of these two composite phosphate liquids and lubricants in the past ten years? Even if one is invented, the past will be explained?

"You have been the deputy director of the factory for nearly ten years, and you can't invent a formula, but you need a technician who has just been transferred to the biotechnology department to work for work to invent it in less than three days, isn't it a bit difficult?

"Not to mention that these two formulas can't have been invented in less than three days after Xiao Guo was transferred to the technical department, even if he really invented them in less than three days, the ownership of these two formulas should also belong to Xiao Guo!

"Because when Xiao Guo came to the biotechnology department, the task given to him by the factory was to be mainly responsible for solving the problems that may arise in the follow-up of the new process of the 75 tractor air filter.

"And the formulas of these two compound phosphating liquids and lubricants that Xiao Guo took out have nothing to do with his own job responsibilities, so no matter how thick-skinned I am, I can't let the factory take possession of these two formulas as service inventions!"
