Chapter 507 Special Steel
"Director Rui..." Duan Yun glanced at the back of the document, frowned and said, "But it says in this document that it must be a product that is applicable, reliable, satisfied by users, best-selling in domestic and foreign markets and enjoys a good reputation... But the problem is that the new products of our factory have not been sold yet, does this comply with the regulations?"

"Didn't your factory already sign a supply and sales contract with our Daxing Automobile Factory before? The supply and sales contract for 11 units is quite a lot, and it is already enough for the best-selling standard..." Ruiyang said.

"But that's an old product, we haven't made a new one yet?" Duan Yun thought for a while, and seemed to think of something, and said repeatedly: "Or the new product is an improved version of our old-fashioned car gearbox?"

"I knew you had enough brains!" Ruiyang chuckled, and said in an approving tone: "We who work in business must have quick brains and know how to be flexible. The reason why I reuse you is because I value you." The kid reacts faster than others!"

"I can't achieve the current results, in fact, I can't do without the support and guidance of Director Rui, otherwise, I will definitely achieve nothing." Duan Yun said with a smile.

"You don't need to flatter me, kid! As I said, I don't look at what you say, but how you do it. In short, before the middle of next month, you must give me a sample. Take it It is very important for your factory and your personal future to show all your skills and level, understand?" Ruiyang said, looking directly at Duan Yun.

"Understood." Duan Yun replied.

"Okay, you take this document away, go back and take a good look for yourself, whether you can seize the opportunity is up to you." Ruiyang signaled Duan Yun to leave.

"Then I'm leaving." After Duan Yun took the document, he turned and left the office.

After walking out of the light industry bureau building, Duan Yun drove back to the factory.

After working overtime at noon, Duan Yun finished installing the digital control panel of the carburizing furnace and started debugging.

After the furnace was started, everything was running normally. Duan Yun and the members of the research team have been standing by the furnace, quietly observing the changes in the operating parameters of the furnace.

He is still a little nervous about his heart. Although he is confident in the design, nothing can be 100% successful. In order to avoid huge losses caused by the failure of the furnace modification, Duan Yun has been guarding the power switch next to the furnace body. Once there is any problem with the furnace, he will cut off the power to the furnace as soon as possible.

For a whole afternoon, Duan Yun used the newly refitted carburizing furnace to carry out the carburizing process of three batches of products. After the heat-treated workpieces were cooled, the workers of the quality inspection team immediately inspected them. After the parameters are qualified, how many people let the workers assemble these qualified gears into finished products, and then the staff of the maintenance team install them on the 212 Jeep.

The newly refitted digital automatic control carburizing furnace was operating normally, and the processed products were all qualified, which made Duan Yun heave a sigh of relief.

At present, Duan Yun only intends to refit one carburizing furnace, and the other one only intends to thicken the outside of the furnace to make it more energy-efficient and economical, but does not intend to carry out digital automatic control transformation.

The reason for this is very simple. Among the gears in the car gearbox, for low-speed and medium-loaded gears, the teeth may break and pitting and wear may occur, so ordinary medium-carbon steel can be used for modulation.

As for gears in high-speed closed transmission, the tooth surface is prone to pitting. This kind of gears can be selected from medium carbon steel for general heat treatment, or simple carburizing treatment.

For the gear part subjected to the largest impact load, it is necessary to focus on selecting high-quality alloy steel for carburizing heat treatment.

If all the gears of the gearbox are processed with the most complicated production process, the cost is somewhat high and it is completely unnecessary.

In addition to the heat treatment process, Duan Yun is also continuing to solve the problem of purchasing new raw materials.

At present, the raw material for processing gears in the factory is No. 45 low-carbon steel. There is no problem in processing ordinary gears with this steel, but for the gears with the largest impact load, 40 CrNa alloy structural steel is required. Steel casting workshops cannot produce this kind of steel, and Duan Yun needs to purchase it from a special steelmaking factory.

Duan Yun still doesn't know that there is no local manufacturer of this alloy steel in Daxing. If there is no one, then Duan Yun can only find a way to purchase from steel factories in Taiyuan or other provinces.

At present, the gear processing accuracy and heat treatment process in Duan Yun's factory are relatively advanced in China, and raw materials have become a core technical problem that Duan Yun will finally solve.

In the early morning of the second day, Duan Yun came to the sales department and called all members of the sales department for a small meeting.

The content of the meeting was very simple. It was to arrange for all members of the sales department. Except for Zhang Xiulan who couldn't escape because of her young child, everyone else had to go on business trips to steel factories in various places, mainly to purchase this new type of alloy steel from steel factories in various places.

Duan Yun offered a bonus of 200 yuan this time. If the salesman can be the first to contact the manufacturer of this steel and persuade the other party to sell the goods to the labor service company, then the 1 yuan bonus will be him, and in the future Honors such as advanced individuals evaluated by the factory will also be given priority.

Duan Yun knows that there are not many steel factories that can produce this alloy steel in this era, and they are generally key national steel factories. Originally, Duan Yun wanted Zhao Changfeng to negotiate with these steel factories one by one, but considering the time constraints, Therefore, we can only cast a wider net and mobilize all the people in the sales department to negotiate.

As the saying goes, there must be a brave man under a big reward. A bonus of 200 yuan is really tempting for these sales staff whose annual salary is only 40 to [-] yuan. Therefore, after making the request, all the staff in the sales department began to enthusiastically Sign up.

As for how to assign the people to which steel factory to negotiate, Duan Yun wrote down several major domestic steel factories into notes, then kneaded them into small groups, and divided the tasks by drawing lots.

After the meeting, all members of the sales department took the address of the manufacturer and left the factory to go home and prepare. In the afternoon or tomorrow morning, they will buy train tickets and go to all parts of the country.

As for whether you can buy steel products, you can only rely on these salesmen and the Eight Immortals to show their magical powers.

After seeing these salesmen leave the factory, Duan Yun stood at the door of the office building and lit a cigarette.

At present, there is only less than a month left before Ruiyang's task of delivering samples to him, but Duan Yun is getting closer and closer to this goal.

After being busy for so long, Duan Yun has finally come to the final step. As long as the raw materials are resolved, his "Longteng" automobile gearbox sample can be successfully produced. As for whether this new type of gearbox can win the National Quality Product Award, I can only resign myself to fate...
