"Director Rui......" Duan Yun swept the back of this document, frowned and said: "But this document says that it must be a product that is reliable, satisfactory to users, and sells well in domestic and foreign markets and enjoys a good reputation...... But the problem is that our new products have not been sold yet, can this comply with the regulations?"

"Didn't your factory sign a supply and marketing contract with our Daxing Automobile Factory before? The supply and sales contract for 11,000 units is quite a lot, which is enough to meet the standard of selling well......," Ruiyang said.

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

"I knew that your kid's brain was enough!" Ruiyang smiled and said in an approving tone: "We people who do business, our brains must turn fast, and we must know how to be flexible, the reason why I reuse you is that I value your kid's reaction faster than others!"

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

"You kid don't need to pat me on the back! I said it, I don't look at what you say, but how you do it, all in all, before the middle of next month, you have to give me a sample, take out all your skills and skills, this is very important for your factory and your personal future, understand?" Ruiyang looked directly at Duan Yun and said.

"Understood. Duan Yun responded.

"Okay, you take this document with you, go back and take a good look at it yourself, whether you can seize the opportunity or not is up to you. Ruiyang motioned for Duan Yun to leave.

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

After walking out of the building of the Light Industry Bureau, Duan Yun drove back to the factory.

After an overtime shift at noon, Duan Yun installed the digital control panel of the carburizing furnace and then started the commissioning work.

After the furnace was started, everything was running normally, and Duan Yun and the members of the research team had been guarding the stove, quietly observing the changes in the parameters of the furnace operation.

For the heart is still a little nervous, although he is confident in the design, but nothing can be 100% successful, in order to avoid the furnace modification failure to cause huge losses, Duan Yun has been guarding the power switch next to the furnace, once there is any problem with the furnace, he will cut off the power of the furnace as soon as possible.

For a whole afternoon, Duan Yun used the newly modified carburizing furnace to carry out three batches of carburizing process treatment, after the heat treatment of the workpiece was cooled, the workers of the quality inspection team tested it for the first time, after the product parameters were qualified, how many people let the workers assemble these inspection qualified gears into finished products, and then the workers of the maintenance team installed him on the 212 jeep.

The newly modified digital automatic control carburizing furnace is running normally, and the processed products are also qualified, which also makes Duan Yun breathe a sigh of relief.

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

As for the reason for this, the gear in the automobile gearbox, for the gear at low speed and medium load, the tooth breakage and pitting wear may occur, and the general medium carbon steel modulation can be selected.

As for the gears in high-speed closed transmission, the tooth surface is easy to pit, and this kind of gear can be selected with medium carbon steel general heat treatment, or simple carburizing treatment.

For the gear part with the greatest impact load, it is necessary to focus on the selection of high-quality alloy steel for carburizing heat treatment.

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

In addition to the heat treatment process, Duan Yun now continues to solve the problem of sourcing new raw materials.

At present, the raw material used for processing gears in the factory is No. 45 low-carbon steel, and there is no problem with this kind of steel processing for general gears, but for the part of the gear with the largest impact load, 40 crna alloy structural steel needs to be used, and the current steel casting workshop of the main factory cannot produce this kind of steel, and Duan Yun needs to purchase it from a special steelmaking plant.

Duan Yun currently doesn't know that there is no local manufacturer of this alloy steel in Daxing, if not, then Duan Yun can only find a way to purchase it from steel mills in Taiyuan or other provinces.

At present, the gear processing accuracy and heat treatment process in Duanyun factory are relatively advanced in China, and raw materials have become a core technical problem that Duanyun finally has to solve.

Early in the morning of the second day, Duan Yun came to the sales department and convened all the members of the sales department for a small meeting.

The content of the meeting is very simple, that is, to arrange all the members of the sales department, except for Zhang Xiulan who can't get out because of the small children, everyone else has to go to various steel mills on business trips, mainly to purchase this new type of alloy steel from steel mills around the country.

Duan Yun offered a bonus of 200 yuan this time, which salesman can contact the manufacturer of this steel for the first time, and persuade the other party to be willing to sell goods to the labor service company, then the 200 yuan bonus is him, and in the future, the factory will evaluate the honor of advanced individuals, and will also be given priority.

Duan Yun knew that there were not many steel mills that could produce this kind of alloy steel in this era, and they were generally national key steel mills, originally Duan Yun wanted Zhao Changfeng to negotiate with these steel mills one by one, but considering the urgency of time, he could only cast a bigger net and mobilize all the people in the entire sales department to go out to negotiate.

As the so-called heavy reward must have a brave man, a bonus of 200 yuan, for these perennial salary of only thirty or forty yuan of sales staff, the temptation is really great, so after the request, all the staff of the sales department have begun to sign up enthusiastically.

As for the question of how to assign everyone to which steel mill to negotiate, Duan Yun wrote several major steel mills in China into slips of paper, and then kneaded them into small balls and assigned tasks by drawing lots.

After the meeting, all the members of the sales department left the factory with the manufacturer's address and went home to prepare, and in the afternoon or tomorrow morning, they would buy train tickets and go to all parts of the country.

As for whether you can buy steel, you can only rely on these salesmen to cross the sea and 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 less than a month left before Ruiyang gives him the task of delivering samples, but Duan Yun is getting closer and closer to this goal.

After being busy for so long, Duan Yun finally came to the last step, as long as the matter of raw materials is solved, his "Longteng" car gearbox sample can be successfully made, as for whether this new type of gearbox can win the National Quality Product Award, it can only be left to fate......
