Return to the exciting era of 1999

Chapter 376 This project is immature

"Mr. Ji, there is absolutely something wrong with this material, I guarantee it with my life!"

In the processing workshop of Yiyuan Manufacturing, Da Qizi and Lao Zhao were standing next to the processing center, pointing at a semi-finished product and arguing loudly, while Ji Donglai rubbed his eyes and yawned.

This metal block was provided by the land-based Wanmeng Group, and it was specially used to process the inner cavity of the core equipment. After Da Qizi finished forging, Lao Zhao led the workers to process it on the machine.

As soon as he did one of them, Lao Zhao eagerly called Ji Donglai. Da Qizi thought that Lao Zhao was looking for his own fault, and at this time the two had a quarrel.

"How did you see it? It stands to reason that there should be no problem with the materials provided by the manufacturer. Lao Qi, you are an expert in this field. Did you notice it when you forged it?"

Looking at the half-processed inner cavity, Ji Donglai's eyes were also full of doubts.As a material student, Ji Donglai knows the material best.

Often subtle changes in carbon content can make the performance of metal materials vary widely. The material required by the manufacturer is DC53, which is rare on the market.

Most of them are imported materials. According to the requirements of the drawings, they must be pure Japanese imported materials. It can be seen that the manufacturer attaches great importance to materials.

"At this stage, I have been busy working on the project of Jingkai Chemical Canada. The processing of this material is relatively simple, so I didn't care. It was handed over to the students. They didn't pay attention to it, and it was forged according to traditional materials."

"It stands to reason that there should be no problem with the materials provided by the manufacturer. If there is a problem, the manufacturer is behind it. Why don't you communicate with the manufacturer?"

Looking at Ji Donglai, Da Qizi felt very depressed.

There is something wrong with this material, and Da Qizi can also see it now. Let alone this material after annealing, it will not deform. This is determined by the physical properties of the material. As a result, it is deformed now, which is obviously wrong.

Coupled with the fact that Lao Zhao processed half of it, a curling knife appeared from this material, which is even more impossible.

All materials have their inherent physical properties, which do not change arbitrarily.

"Cut a piece, and I'll go to the laboratory to do a crystal phase test. Besides, Lao Qi, don't you claim to be an expert in this industry? Give me a piece of this material. If you succeed, you will be credited with it. If you can't, give it to me quickly." You also have Du Jingbiao’s contact method for contacting material suppliers, so you must not delay me, you know? The matter of materials must not be sloppy at all.”

Instruct the people at the scene to cut the materials for themselves, and Ji Donglai directed Da Qizi. At this time, Da Qizi was not in a good mood. After coming to the factory for so long, something happened and the leader knew about it. Da Qizi Very embarrassing.

"Let's buy it. This stuff is not an ordinary material. I'll call right away. We're close to Shougang. Even scrap materials are much better than our own. I'll do it right away."

Shrinking his neck, Da Qizi finally lowered his head and chose not to take the risk.

This thing is definitely not a joke. The rest of the materials are okay. This kind of hot work abrasive steel will fail to deal with any problems on it. If you really can’t adjust it, what should you do if you can’t get the boss’s new account and old account together.

Ji Donglai immediately took the materials into the laboratory of Capital University of Technology, and within 15 minutes, the results of the crystal phase test came out.

"It's absolutely impossible to be DC53. Who knows what material they are. In fact, it's a bunch of things made of unknown materials. You can see."

Looking at the chaotic appearance of crystals, one of Ji Donglai's seniors curled his lips, and Ji Donglai's head buzzed.

"Brother, this is a small thing that the students brought back from Seoul. It is not a respect for you to share a share. I have to leave before I have time to treat you to dinner."

After sharing the small gift with Senior Brother Zhong, Ji Donglai hurriedly brought the report and samples to Mr. Deng.

"you sure?"

Looking at Ji Donglai's test report, and then looking at the samples, Mr. Deng's expression became serious.

At this stage, the project of the big leader has been going smoothly. Various parts produced by Ji Donglai have been in place one after another, and they are being installed according to the design requirements.

Now that there is a problem with the core components, Mr. Deng feels that the matter is unusual.

Thinking about Lu Lu again, the other party has been in the country and did not show any abnormalities. The other party did not have the courage to replace the raw materials, and the result was about to come out... While speaking, Mr. Deng looked at the rows of machines downstairs.

"The crystal phase can't be wrong. This material enters our factory from unpacking to processing. The whole process is on our side. This material is rarely used because it is too expensive, so it is not bad. I am now urgently dispatching some domestic ones. The materials are here, and no matter what, we must ensure that this product is delivered on time, even if I spend my own money."

Thinking of the high cost of this component, Ji Donglai felt blocked.When the manufacturer's materials came, they came with the test report of the materials. Ji Donglai had no doubts about this group of people, and he didn't expect this kind of shit to happen.

Thinking about it now, Ji Donglai should have carried out a crystal phase test at that time, but now he has suffered a dumb loss.

"Calculate these expenses, and I will make up for you from other places. Don't let other people know about this, especially the Lulu group. I want to see what these people want to do."

Mr. Deng absolutely believes in Ji Donglai's character, and it's okay for Ji Donglai to come here, so it must be the intention of the other party.This project has been full of twists and turns, Mr. Deng is now in charge, and the other party wants to see what these people are doing.

With Mr. Deng's assurance, Ji Donglai hurriedly nodded.Called Da Qizi to start buying. The cost of materials alone was 62, which was still leftover materials. This time, Ji Donglai was more careful. The first thing to do when materials were put into storage was to make crystal phases.

This time Da Qizi didn't dare to push him too hard, he handled the materials himself, and every step was strictly carried out according to the process.

"This material is the right one. If you don't talk about it, you can tell just by listening to the sound of the knife cutting iron filings. Chachacha... The material is dull, and the more miscellaneous the sound, the more wrong it will be."

Putting the semi-finished product on the machine tool again, Lao Zhao finally felt at ease, and Ji Donglai nodded.

In seven days, all the machine tools were put into battle. Ji Donglai followed the scene almost every day. From the inner lining to the outer lining, from machining to heat treatment, nothing like the past happened again. In order to verify his conjecture, Ji Donglai Come to process the raw materials provided by the land side into a set of products, and put them directly into the furnace.

By comparison, the result is obvious.

The materials provided by Lu Lu's group were severely deformed, and the materials Ji Donglai bought from Shougang were all right.

"Old Yuan, find me a few professionals in mechanical design, especially the kind of masters. Our current manufacturing of many equipment is still in the experience stage, this will not work."
