"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 them, Lao Zhao called Ji Donglai eagerly. Da Qizi thought Lao Zhao was looking for trouble with him, and the two had a heated argument.
"How can you tell? Logically speaking, there shouldn't be any 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 knows materials best.
Often subtle changes in carbon content can make the performance of metal materials vary widely. The material required by the manufacturer is C53, which is rare on the market.
Most of them are imported materials. According to the drawing requirements, they must be pure imported materials from Japan. 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 material processing is relatively simple, so I didn't pay attention to it. 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.
Coupled with the fact that Lao Zhao processed half of this material and a sharpener appeared, this is even more impossible.
All materials have inherent physical properties that 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 can successfully do it, give it to me as soon as possible. Contact the material supplier. You also have Du Jingbiao’s contact information. You must not delay the matter for me, you know? You can’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 is any problem on it. If the boss really can't reconcile the old and new accounts together, what should he 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 C53. Who knows what materials they are made of. In fact, this is a bunch of stuff made of unknown materials. Look at it."
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 little 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.
"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 smoothly. Various parts produced by Ji Donglai have been put in place and installed according to the design requirements.
Now that there is a problem with the core components, Mr. Deng feels that something is unusual.
Think again about land routes
, 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... While speaking, Mr. Deng looked at the rows of machines downstairs.
"The crystal phase is unmistakable. The entire process from unpacking to processing of this material after it enters our factory is on our side. 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 felt heartbroken. When the manufacturer's materials came, they came with the material's test report. Ji Donglai had no doubts about this group of people, but he didn't expect that such a bad thing would happen.
Thinking about it now, Ji Donglai should have carried out crystal phase testing 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 Lu Lu's group. I want to see what these people want to do."
Mr. Deng absolutely believed in Ji Donglai's character. If there was no problem for Ji Dong to come here, then the other party must have done it on purpose. This project has gone through twists and turns. 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 nodded quickly. He called Da Qizi to start purchasing the goods. The cost of materials alone was 620,000 yuan, which was still leftover material. This time Ji Donglai was more thoughtful. The first thing he did when the materials were put into storage was to make crystal phases.
This time, Da Qi Zi did not dare to rely on Da Da. He processed the materials himself, and strictly followed the craftsmanship in every step.
"This material is the right one. If nothing else, you can tell by just 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 him at the site 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 Lai also processed the raw materials provided by the land route 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, but 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 experts. Many of our equipment manufacturing are still at the experience stage, and this won't work."
