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

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

This metal block was provided by the Wanmeng Group overland and was specially used to process the inner cavity of the core equipment. After it was forged at Daqizi, Lao Zhao led the workers to process it on the machine.

As soon as he did one of these things, Lao Zhao called Ji Donglai eagerly. Da Qizi thought Lao Zhao was looking for trouble with him, and the two had a heated argument at this time.

"How can you see it? Logically speaking, there should be no problems with the materials provided by the manufacturer. Lao Qi, you are an expert in this field. Did you see it during forging?"

Looking at the half-processed inner cavity, Ji Donglai's eyes were full of doubts. As a student of materials, Ji Donglai knew the materials 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 drawing requirements, they must be purely imported from Japan. It can be seen that the manufacturer attaches great importance to the materials.

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

"It stands to reason that there shouldn't be any problems with the materials provided by the manufacturer. If there is a problem, it is the manufacturer who is behind it. Why don't we communicate with the manufacturer?"

Looking at Ji Donglai, Da Qizi felt very depressed.

Da Qizi can now see that there is something wrong with this material. Among other things, the material will not deform after annealing. This is determined by the physical properties of the material. The result is that it has deformed now, which is obviously wrong.

In addition, Lao Zhao processed half of the material and a sharpener appeared on this material, which is even more impossible.

All materials have their inherent physical properties and cannot be changed at will.

"Cut a piece, and I'll go to the laboratory for crystal phase testing. Also, Lao Qi, don't you claim to be an expert in this industry? Give me a piece of this material. If you succeed, give it to me. If you can't do it, just give it to me.

To contact the material supplier, Du Jingbiao’s contact information is also available. You must not delay the matter for me, you know? Don’t be careless about the materials.”

Instructing the people on site to cut the materials into pieces for him, Ji Dong came to direct Da Qi Zi. At this time, Da Qi Zi felt uncomfortable. He had been in the factory for so long and something like this had happened and the boss knew about it. Da Qi Zi

Very shameless.

"Let's buy it. This stuff is not an ordinary material. I'll call right away. We are close to Shougang. Even getting scraps is much better than making it 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 okay. This kind of hot-work abrasive steel will fail if there are any problems on it. If you really can't reconcile the boss's old and new accounts, what should you do?

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

"This definitely can't be DC53. Who knows what materials they are made of. In fact, this is a bunch of stuff made of unknown materials put together. Take a look."

Looking at the chaotic appearance of the crystal phase, one of Ji Donglai's senior brothers curled his lips, and Ji Donglai's head buzzed.

"Brother, this is a small thing that the students brought back from Seoul. It would be disrespectful for you to share it. I have to leave first and treat you to dinner when I have time."

After dividing the small gifts 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 at the samples, Mr. Deng's face began to look solemn.

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

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

Thinking about Lu Lu again, the other party has been in the country and has not shown any abnormality. The other party does not have the courage to replace the raw materials, and the results are about to come out... As he spoke, Mr. Deng looked at the rows of machines downstairs.

"The crystal phase cannot be wrong. When this material enters our factory, the entire process from unpacking to processing is carried out by us. This material is rarely used because it is too expensive, so it will not be bad. I am now asking someone to urgently transport some domestic materials.

Once the materials are delivered, I must ensure that the product is delivered on time no matter what, even if I spend my own money to do so."

Thinking of the high cost of this part, Ji Donglai was heartbroken. When the manufacturer's materials arrived, they came with a test report of the material. Ji Donglai had no doubts about these people, and he didn't expect such a bad thing to happen.

.

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

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

Mr. Deng absolutely believes in Ji Donglai’s character. If there is no problem with Ji Dong coming here, then the other party must have done it on purpose. This project has gone through twists and turns, and now Mr. Deng is in charge. The other party wants to see what these people are doing.

With Mr. Deng's guarantee, Ji Donglai nodded quickly. He called Da Qizi to start purchasing goods. The cost of materials alone was 620,000. This was still leftover material. This time Ji Donglai was more thoughtful and the materials came in.

The first thing Ku did was to do the crystal phase.

This time, Da Qi Zi did not dare to rely on Da Da. He processed the materials himself, and strictly followed the craftsmanship at every step.

"This material is the right one. If nothing else, you can tell just by listening to the sound of the knife cutting the iron filings. Crack, click, click... the material is dull. The more foreign materials there are, the more wrong the sound will be."

After 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 action. Ji Donglai followed at the scene almost every day. From the inner lining to the outer lining, all the processing was completed, from processing to heat treatment. Nothing like the past happened again. In order to verify his conjecture, Ji Donglai

I came to process the raw materials provided by the overland side into a set of products and put them directly into the furnace.

By comparison, the results are obvious.

The materials provided by Lu Lu's group were severely deformed, while the materials Ji Donglai bought from Shougang had no problems at all.

"Lao Yuan, find me some experts in mechanical design, especially those who are big ones. Many of our equipment manufacturing are still at the experience stage. This won't work."
