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

"Yeah, why not?"

Huang Yaohui was also stamping his feet anxiously and asked Zhai Yuqiang:

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

, Under such circumstances, we are still unable to ensure that our factory can process special slender bolts using cold heading technology?"

"Director Xiao, Director Huang,"

Zhai Yuqiang sighed and said: "The key to the problem is not the cold heading mold and the entire cold heading process. The key lies in the treatment of high-grade chromium-molybdenum nitride alloy steel bars before cold heading."

Having said this, he turned to look at Luo Daojun,

"Director Luo, the process of processing special slender bolts using turning technology currently used in the factory was invented by me. But before deciding to use turning technology to produce special slender bolts, I also tried to see if I could use heat treatment to produce special slender bolts.

Forging process and cold heading process are used to process special slender bolts.

“The result of the test is that although the hot heading process can process special slender bolts that meet quality requirements, the production cost is almost the same as the cost of processing special slender bolts using the turning process, and it also requires large-scale overhaul of the factory equipment.

Renovation and renovation are extremely cost-effective.

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

"So in the end, after careful consideration, we finally decided to use horse machining technology to process special slender bolts."

"Lao Zhai,"

Although Xiao Guoneng is the deputy director in charge of production, he is only slightly better than Huang Yaohui in terms of specific technology. At this time, listening to what Zhai Yuqiang said, 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, the scrap rate is extremely high, and the finished products do not meet the requirements, then why is it okay for Xiao Guo to use the cold heading process to process special slender bolts?"

"Director Xiao, it's just like what I just said,"

Zhai Yuqiang replied: "The key to the problem does not lie in the cold heading mold and the entire cold heading process. The key lies in the treatment of high-grade chromium-molybdenum nitride alloy steel bars before cold heading."

"What about the processing of high-grade chromium-molybdenum nitride alloy steel rods?"

Xiao Guoneng was not a complete technical expert. He frowned and said: "You mean, Xiao Guo has adopted a certain process to specially treat high-grade chromium-molybdenum nitride alloy steel rods, so he can use cold

Can the upsetting process produce special slender bolts that meet the requirements?"

"Yes, that's what it means."

Zhai Yuqiang nodded and said:

“Generally speaking, when processing metal parts using the cold heading process, the raw materials need to be phosphated before processing, and then lubricants must be added during processing to ensure the processing yield and product quality.

"However, the material properties of high-grade chromium-molybdenum nitride alloy steel rods are quite special. I tried various formulas of phosphating solutions and lubricants, but none of them could improve the material properties of high-grade chromium-molybdenum nitride alloy steel rods. Therefore,

As a result, the scrap rate during the processing process is high and the quality of the finished product does not meet the design requirements.

“The key reason why Xiao Guo was able to use the cold heading process to produce qualified special slender bolts this time was that he used a special proportion of compound phosphating liquid and a special proportion of lubricant to nitride high-grade chromium molybdenum.

Alloy steel rods are pre-treated, thereby changing the material properties of high-grade chromium-molybdenum nitride alloy steel rods.

"As long as we don't master the special formulas of the two composite phosphating fluids and lubricants that Xiao Guo has in his hands, we will never be able to use the cold heading process to process qualified special slender bolts."

So this is ah!

Luo Daojun suddenly realized it and admired Guo Yonghe even more.

This young man really cannot be described as an ordinary genius. Not only can he repair various advanced mechanical equipment, but he also masters such advanced special material formulas. No wonder he has the confidence to contract a labor service company to produce special slender bolts.

!

Xiao Guoneng pondered for a moment and asked:

"Lao Zhai, have you seen the composite phosphating liquid and lubricant that Xiao Guo used in the trial production workshop today? Then is there any way for you to analyze the components of the composite phosphating liquid and lubricant, and then we can do it ourselves?

Preparation?”

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

Zhai Yuqiang shook his head and smiled bitterly: "Not to mention me, I am a professor specializing in metal processing at Zhongtian University. Just relying on some finished products of compound phosphating liquid and lubricant, even if it takes four or five years, I may not be able to find the correct solution."

recipe."

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

"Director,"

Huang Yaohui was still a little unwilling. He rolled his eyes and said righteously to Luo Daojun: "Xiao Guo is a cadre of the Biotechnology Department, so the formula of the compound phosphating solution and lubricant should also be a service invention.

"So he should hand over these two formulas to the factory instead of keeping them to himself. Wait a minute and see if you can do some ideological work specifically for him in this regard?

"The worst case scenario is like solving the problem of the air filter of the Type 75 tractor. I'll reward him with a bonus of two thousand yuan!"

Luo Daojun coughed and said seriously to Huang Yaohui:

"Service invention? Director Huang, our factory doesn't take responsibility for this!"

"It took less than three days for Xiao Guo to be transferred to the Biotechnology Department. Before that, he had been working as a cleaner in the metal processing workshop. Do you think that inventing such high-end compound phosphating fluids and lubricants is a way to clean the workshop?

Is it the scope of the worker’s responsibilities?”

Xiao Guoneng laughed dryly and defended Huang Guohui: "Director, what if he invented these two special formulas in less than three days in the Biotechnology Department?"

"Invented in less than three days?"

Luo Daojun couldn't bear it anymore. He 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 haven't you invented the formulas for these two compound phosphating fluids and lubricants in the past ten years? Even if you invent one, you will be responsible for it.

In the past?

"You have been the deputy director of the factory for nearly ten years and have been unable to invent a formula, but you asked a technician who was just transferred to the Biotechnology Department to do work for you to invent it in less than three days. Isn't it a bit overwhelming?

"Don't say that these two formulas could not have been invented by Xiao Guo in less than three days after he was transferred to the technical department. Even if he really invented them in less than three days, these two formulas

The ownership should also belong to Xiao Guo!

"Because when Xiao Guo came to the Biotechnology Department, the factory gave him the task of mainly solving problems that may arise in the future with the new process of the 75 tractor air filter.

"The two formulas of compound phosphating liquid and lubricant that Xiao Guo came up with 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 from him as employee inventions.
