Smart Industrial Empire

"It's good if there is no problem. Now let someone inspect the size of these products, and then make a record. After cleaning, weigh and seal the package, otherwise it will be oxidized..." The temperature is a bit high these days, even if it is not easy to get along with oxygen The reacted tungsten and molybdenum atoms will be oxidized soon under the hot air.

The finished product of pure molybdenum crucible is silvery white. If it is oxidized, many gray spots will appear due to the density problem, making the appearance of the whole product too ugly.

"By the way, Xiao Zhang, have the purity and density of our batch of sintered crucibles been sent to the physical and chemical analysis room for testing? If the purity and density cannot meet the requirements of Jiuyi materials, it will be troublesome..."

Xue Daoming, who had just breathed a sigh of relief, suddenly remembered that the small molybdenum crucibles produced in previous batches were rejected by Jiuyi Materials because the purity did not reach 99.95% proposed by Jiuyi Materials, only 99.8%; At the same time, the density has not reached the 9.98gcm3 proposed by Jiuyi Materials. It is precisely because of this problem that the small molybdenum crucible, which originally took only three days to produce, has not been delivered until now.

"Leader, the density has been reached, but the purity is still a bit different, only 99.91%-99.96%, this..." Upon hearing this, Zhang Defu, who was originally full of confidence, suddenly became sad.

Although the process was proposed by Jiuyi Materials, Jiuyi Materials only provides a range for many production parameters, but not accurate to specific values.

This made the technicians of the Seventh Five-Fourth Factory very painful.

But they also know.The isostatic pressing after the powder filling is carried out, the pressure is different, and the holding time is different, and the produced molybdenum crucibles will have slight differences.

The issue of purity is the issue of raw materials.

What is the purity of the molybdenum powder supplier? components can be used.That's all.Xue Daoming had to cry blind.

"Hey! We'll just have to wait and see what Yun Fei will say when he comes. Get the test report ready. I think he's coming soon." Xue Daoming also knows about purity.They can control.Just a small fraction.

Pure tungsten powder.They are all obtained through chemical reduction reactions, and they can only be purified in a small range in the physical and chemical analysis laboratory, which is important.It is still the sieving process of the first process. If those relatively large grains cannot be selected, it is impossible to achieve too high a density.

"Mr. Yun, Mr. Xue has gone to the fifth branch factory. Why don't you sit in the reception room for a while and I'll call Mr. Xue?" As soon as Yun Fei appeared at the gate of the Seventh Five-Fourth Factory, Chen Xiaoqiong was waiting for him in the guard room He rushed out and said to Yun Fei who was stopped outside the door without a car.

"It's okay, I'll just go directly to the fifth branch factory. The purpose of my visit is to go to the fifth branch factory to see our products..." Yun Fei said with a smile to this middle-aged woman who wanted to introduce herself to someone.

"..." Chen Xiaoqiong was stunned, but Xue Daoming told her to invite Yun Fei to the office first, and wait for him to come back from the fifth branch...

But now that Yunfei wants to go directly to the fifth branch factory, how can she have any good reason to stop Yunfei?

Could it be telling Yunfei that Xue Daoming has no confidence in the products produced by the fifth branch factory?Do you have to confirm it before you come back and bring Yunfei to see it?

If so, Xue Daoming will definitely kill her!

"Mr. Yun, why did you come directly to the workshop?" Seeing Yun Fei bringing two sturdy middle-aged men into Zhang Defu's office in the fifth branch factory, didn't he ask Chen Xiaoqiong to stop Yun Fei at the door?

"If I don't see the finished product, I can't let it go. Mr. Xue, you haven't seen my chief engineer Deng Lanqing before. He is extremely tough. He comes to my office every day to make a fuss. Who can stand it?" Yun Fei said with a non-smiling smile.

The whole city of Deng Lanqing knew about Deng Lanqing's aggressiveness.

When she was conducting the experiment, Xie Heping brought some clients who were interested in investing to visit the Jiuyi Research Institute, and wanted to make Deng Lanqing stop the experiment and introduce it to the clients, but was kicked out by Deng Lanqing who had not made progress for a long time After entering the laboratory, the whole city of Chengdu knew about it.

Even Sichuan girls, who are known for their pungentness, are weak compared to Deng Lanqing, a northern girl.

"Boss Yun was joking. There will never be such a thing again..." Hearing Yun Fei's words, Xue Daoming suddenly felt that the weather in the morning became hot in an instant.

If Deng Lanqing came to the door, it would not be so easy to talk to Yun Fei.

In the eyes of many people, Deng Lanqing is a lunatic!

A shrew!

If I let this woman come to my door, how can I live my life?

"Where is the first batch of products? Let's take a look first. If I don't see the finished product, I really can't let it go!" Yun Fei was telling the truth.

This thing is too critical for the research of NdFeB.

Many projects are waiting for materials to be put into the pot.

In the past two years, with the rapid development of China's electronic information industry, automobile industry and other industries that require NdFeB rare earth permanent magnet materials, China has more and more requirements for these high-performance rare earth permanent magnet materials, and foreign countries have monopolized these high-performance There are not many manufacturers of materials, and they have formed a price alliance against China. Now they are preparing to increase the price significantly, and they are negotiating with China!

The September [-]st Research Institute has not had much of this kind of material in reserve.

Sensors for production equipment are needed, sensors for research robots are also needed, and computer hardware research is also needed, and with the acceleration of research progress, the demand is increasing...

"Did these molybdenum crucibles get wet?" The small molybdenum crucibles in the first furnace were not big, with a diameter of only 140mm, which was not that big.Yun Fei frowned as soon as he took the product into his hands.

It must be that these guys started to take out the furnace before the temperature in the furnace was completely cooled to normal temperature, and the sweat of the workers dripped on it, otherwise, no matter how hot the weather is, the sintered small molybdenum crucible would not be oxidized so quickly of……

"No, after we took it out, we cleaned it with alcohol. How could it be stained with water?" Seeing a few finger-thick gray spots on the bottom of the crucible in Yunfei's hand, fine sweat began to break out on his forehead pearls.

The purity and density of this product are not enough, just the problem of oxidation is a troublesome thing.

Everyone's sweat contains salt!

Moreover, the small molybdenum crucible used for sintering rare earth permanent magnets cannot be washed with lye or acid water, otherwise, the acid or alkali remaining inside the crucible will cause damage to the rare earth permanent magnets in the crucible...

"Sweat!" Yun Fei said coldly.

At high temperature, salt water can quickly react with molybdenum atoms...

"This, this..." Xue Daoming suddenly became anxious.For the production process of this small molybdenum crucible, more than a ton of materials were wasted, plus labor, energy and other costs, hundreds of thousands of costs!

If Yunfei canceled the order because of this, there will be no follow-up orders, so what?

Domestic companies that can use small molybdenum crucibles simply look down on companies that have just entered the industry like them.

If it cannot create benefits in a short period of time, it is very likely that it will be sold or directly closed by the entire Chengdu City Government!

In recent years, too many companies have gone bankrupt in China.

"Let's not talk about this issue for now, Mr. Xue, how about the technical conditions of these small molybdenum crucibles?" Seeing those spots that were rapidly oxidized due to the sweat of the workers, Yun Fei felt secretly refreshed, and was worried that he could not find how to deionize the crucibles. The technical process of water anti-oxidation was sold to the Seventh Five-Fourth Factory.

It's literally drowsiness meets the pillow.

As long as these products meet their technical standards, then selling this anti-oxidation technology to them is absolutely certain.

Many semi-finished products such as wooden discs, tungsten target blanks, and molybdenum blanks produced by the No. [-] Branch Factory of Seventh Five-Fourth were returned by Jiuyi Materials because the anti-oxidation technology was not up to standard. These materials used in electronic products, You can't use acid and alkali to clean it at all...

This technology will not be sold much, and the Seventh Five-Fourth Factory will pay 50 million, which is almost the same.

There are quite a few companies in China that need such technology, and even if they sell ten of them, they can earn an income of RMB 500 million.

This is far more than an investment!

Hundreds of percent profit.

"Mr. Yun, this, due to the immaturity of the craftsmanship, the purity is still a little bit unable to meet your requirements..." Zhang Defu on the side said it to Yun Fei with a face full of embarrassment.

Yun Fei was stunned.

Nima, it has been several months, and the production process is not yet mature?I provided a complete production process at the beginning, although it took three or two more times, I was able to grasp the parameter range!

"Tell me the specific data, how much is the difference? A difference of one percent is a little bit, and one tenth of a percent is also a little bit!" Yun Fei's face began to turn cold.

Just talk about the data directly, and you can understand how much the difference is at once!

Actually, I said a little bit in general!

"The purity is only 99.91%-99.96%, this..."

"All?" Yun Fei frowned.

Regardless of whether it is a tungsten crucible or a molybdenum crucible, the purity of 99.95 is the minimum standard.The higher the purity of the crucible, the longer the service life.

Even at 99.95% density, the service life of these crucibles is generally three months later!

The cost of a small molybdenum crucible of about five kilograms is about 3000 yuan. In the cost of producing NdFeB rare earth permanent magnets, the cost is about 30 yuan per kilogram!

If the service life is short for one day, the cost will have to increase...

"Yes, Mr. Yun, we will definitely improve in the future, but this, you see..." Wu Daoming now has the heart to strangle the people in the production department and the marketing department. If it weren't for them, where would such a problem arise? ?

"You mean to give in and accept?" (To be continued...)
