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

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

This metal block was provided by the Wanmeng Group on the land route, which was specially used to process the inner cavity of the core equipment, and the forging was completed by Daqizi, and Lao Zhao took 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 the two quarreled at this time.

"How do you see that? 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 area, can you see it when you forge?"

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

Subtle changes in carbon content can make the properties of metal materials vary greatly, and the material required by the manufacturer is C53, which is rare on the market.

The vast majority of them are imported materials, and according to the requirements of the drawings, they must be pure Japanese imported materials, which shows that the manufacturer attaches great importance to the materials.

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

"It stands to reason that there should be no problems with the materials provided by the manufacturer, and if there is a real problem, the manufacturer is on the back, why don't you communicate with the manufacturer?"

Looking at Ji Donglai, Da Qizi was very depressed.

There is a problem with this material, and now it can be seen that the material at the end of annealing will not be deformed, which is determined by the physical properties of the material, and the result is now deformed, which is obviously wrong.

In addition, Lao Zhao processed half of it, and a rolling knife appeared in this material, which is even more impossible.

All materials have their own inherent physical properties that do not change at will.

"Cut a piece, I'll go to the laboratory to do crystallographic testing, and Lao Qi, don't you claim to be an expert in this industry, give me a piece of this material, I can successfully give you the first credit, if you can't do it, hurry up and contact the material supplier for me, you also have the contact information of Du Jingbiao, and you must not delay me, you know?" The material thing is not to be sloppy at all."

instructed the on-site people to cut the materials into pieces, Ji Dong came to command Da Qizi, at this time Da Qizi was not a taste in his heart, he had come to the factory for so long and had such a little thing and was known by the leader, Da Qizi was very faceless.

"Let's buy it, this thing is not an ordinary material, I'll call immediately, we're close to Shougang, even the leftovers are much stronger than we get them ourselves, I'll do it right away."

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

This thing is definitely not a joke, the rest of the materials are good to say, this kind of hot work abrasive steel, there is a little problem in the processing will fail, and it really can't be adjusted out of the boss's new accounts and old accounts together.

Ji Donglai immediately brought the materials into the laboratory of Capital University of Technology, and within fifteen minutes, the crystalline phase test results came out.

"It can't be C53, hell knows what material they are. Actually, it's a bunch of stuff that doesn't know what material to put together, you see."

Looking at the chaotic appearance of the crystal phase, one of Ji Donglai's senior brothers pouted, and Ji Donglai's brain buzzed.

"Senior brother, this is a small thing that the students brought back from Seoul, you share a point, it is not a respect, I have to leave in advance, and I have time to invite you to dinner."

After dividing the small gift with Senior Brother Zhong, Ji Donglai hurriedly found Mr. Deng with the report and samples.

"Are you sure?"

Looking at Ji Donglai's test report, and then looking at the sample, Mr. Deng's face began to be solemn.

At this stage, the project has been going very smoothly, and various parts and components produced by Ji Donglai have been in place one after another, and they are being installed in accordance with the design requirements.

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

Think overland again

, the other party has been in the country, and has not shown anything abnormal, the other party does not have the courage to change the raw materials, and the result is about to come out...... As he spoke, Mr. Deng glanced 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 will not be bad. I'm going to have some domestic materials urgently come over now, and I have to make sure that this product is delivered on time no matter what, even if it's at my own expense."

Thinking of the expensive cost of this part, Ji Donglai's heart was blocked. When the manufacturer's materials came, they came with the test report of the materials, and Ji Donglai did not suspect that he was in this group, but he didn't expect this kind of bad thing to happen.

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

"Calculate these expenses, I'll make it up for you from somewhere else, and don't let the rest of the people know about it, especially the land guys, I'm going to see what these guys want to do."

Mr. Deng absolutely believes that Ji Donglai is a person, and Ji Dong is no problem when he comes here, so it must be the other party's intention. This project has had twists and turns, and now Mr. Deng is in charge, and the other party wants to see what these people are doing.

With Mr. Deng's assurance, Ji Donglai hurriedly nodded. Call Daqizi to start purchasing, the material cost alone is 620,000, this is still leftovers, this time Ji Donglai has an extra eye, the first thing the material is to do the crystalline phase.

This time, Daqizi didn't dare to hold it up, and personally processed the materials, and every step was strictly carried out in strict accordance with the process.

"This material is right, don't say anything, you can judge by listening to the sound of the knife cutting iron filings, click...... The material is stuffy, and the more that miscellaneous the material is, the more wrong it will be."

Put the semi-finished products on the machine tool again, Lao Zhao's heart was finally stable, 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 and the outer lining were all processed, from processing to heat treatment, there was no such thing as the past, in order to verify his conjecture, Ji Donglai also processed a set of products from the raw materials provided by the land side, and put them directly into the furnace.

By contrast, the results are clear.

The materials provided by the Lu Lu gang have been seriously deformed, and the materials that Ji Donglai bought from Shougang have no problems at all.

"Lao Yuan, find me a few mechanical design professionals, especially that kind of master, many of our current equipment manufacturing is still in the experience stage, this is not good."
