Intelligent Industrial Empire

"It’s fine if there is no problem. Now let someone check 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 follow the oxygen The reacted tungsten and molybdenum atoms will soon be oxidized in the hot air.

The pure molybdenum crucible is silver-white in the finished state. If it is oxidized, a lot of gray spots will appear due to density problems, making the appearance of the whole product too ugly.

"By the way, Xiao Zhang, have the purity and density of our sintered crucibles sent to the physical and chemical analysis room for testing? If the purity and density cannot meet the requirements of the September 1st material, it will be troublesome..."

Xue Daoming, who had just breathed a sigh of relief, suddenly remembered that the small molybdenum crucibles produced in the previous batches were rejected by the 91 materials because the purity did not reach the 99.95% proposed by the 91 materials, and only 99.8%; At the same time, the density did not reach the 9.98gcm3-10.03gcm3 proposed by Jiuyi Materials. Because of this problem, the small molybdenum crucible, which originally only took three days to produce, has not been delivered until now.

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

Although the craftsmanship was proposed by the 91 Materials, many production parameters, but the Jiu Yi Materials only provide a range, and do not have precise values.

This makes the technicians of the 754 factory very painful.

But they also know that the molybdenum crucibles produced will have slight differences in the isostatic pressing after the powder is loaded, the pressure is different, and the holding time is different.

The issue of purity is a matter of raw materials.

The purity of the molybdenum powder suppliers provided them, and they had no choice. Just for the nine-one research institute's order of about 30,000, they bought several meals of raw materials and spent hundreds of thousands of material costs, if not for the production of some electronics If the components can be used, Xue Daoming has to cry blindly because of this.

"Hey! This is only a while to see what Yun Fei said, get the test report ready, I guess he will be there soon." Xue Daoming also knows that in terms of purity, they can control only a small part.

Pure tungsten powder is obtained through chemical reduction reaction, and they can only carry out some small-scale purification in the physical and chemical analysis laboratory. The most important thing is the sieve powder in the first step. If the particles cannot be larger When the crystal grains are selected, it is impossible to achieve too high density.

"Mr. Yun, Mr. Xue went to the fifth branch factory, or sit in the reception room for a while and I call Mr. Xue?" Yun Feigang appeared at the door of the 754 factory, waiting for him in the guard room, Chen Xiaoqiong He rushed out and said to Yun Fei who hadn't been stopped by the car yet.

"It's okay, I can go directly to the fifth branch factory. My purpose is to go to the fifth branch factory to see our products..." Yun Fei smiled and said to the middle-aged woman who wanted to introduce herself to her.

"..." Chen Xiaoqiong was stunned, but Xue Daoming told her that Yun Fei must be invited to the office first, waiting for him to return from the fifth branch...

But now Yunfei wants to go directly to the fifth branch, what good reason does she have to stop Yunfei?

Could you tell Yun Fei that Xue Daoming has no confidence in the products produced by the fifth branch?Do you need to check before you come back and take Yunfei to see?

If that were the case, Xue Daoming would definitely kill her!

"President Yun, why did you come directly to the workshop?" Seeing Yun Fei bring two sturdy middle-aged men into the office of Zhang Defu of the fifth branch, didn't he let Chen Xiaoqiong stop Yun Fei at the door?

"If I don't see the finished product, I can't let it go, Mr. Xue, my chief engineer, Deng Lanqing, have you never seen it. You are so sturdy and sturdy. Who can stand it?" Yun Non-skinny said without a smile.

Deng Lanqing's Biaohan and Spicy are known throughout Rongcheng.

When she was experimenting, Xie Heping brought some customers with investment intentions to visit the Jiuyi Research Institute, and wanted to stop Deng Lanqing from the experiment and introduce it to the customers, but was driven out by Deng Lanqing, who had not made progress for a long time. After the laboratory, the whole Rongcheng knew.

Even the Sichuan girl, who is known for her pungency, is weaker than Deng Lanqing, a northern girl.

"Mr. Yun is joking. There will be no such thing again..." Hearing Yun Fei's words, Xue Daoming suddenly felt that the weather in the morning became hot instantly.

If Deng Lanqing were to come to the door, it wouldn't be Yun Fei's good talk.

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

A shrew!

If I let this woman come, how can I live my own 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 go of it!" Yun Fei was telling the truth.

This thing is too crucial for the research of NdFeB.

Many projects are waiting for the materials to be cooked.

In the past two years, with the rapid development of industries that require neodymium-iron-boron rare-earth permanent magnet materials such as China’s electronic information industry and automobile industry, China has increasingly demanded these high-performance rare-earth permanent magnet materials, and foreign countries monopolize these high-performance There are not many manufacturers of materials, and they have also formed a price alliance against China. Now they are preparing to increase prices significantly and are negotiating with China!

The Jiuyi Research Institute has not many such materials.

The sensor needs of production equipment, the sensor of research robots, and the research of computer hardware are also needed, and with the acceleration of research progress, the demand is increasing...

"Are these molybdenum crucibles wet?" The small molybdenum crucible of the first furnace is not big, only 140mm in diameter, not much.As soon as Yun Fei got the product in his hand, he frowned.

These guys must have started to take the furnace before the temperature in the furnace has completely cooled to normal temperature. Workers’ sweat dripped on it. Otherwise, no matter how hot the weather is, the sintered small molybdenum crucible will not be oxidized so quickly. of……

"No, after we took it out, they were all cleaned with alcohol. How could it be stained with water?" Seeing the thick gray spots on the bottom of the crucible in Yunfei's hand, fine sweat began to erupt on his forehead Beads out.

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

Human sweat is salty!

Moreover, the small molybdenum crucible used for sintering rare earth permanent magnets should not be washed with lye or acid water. Otherwise, the acid or alkali remaining in the crucible will damage the rare earth permanent magnets in the crucible...

"Sweat!" Yun Fei said coldly.

At high temperatures, 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 one ton of materials was wasted, plus labor, energy and other costs, which cost hundreds of thousands!

If Yunfei cancels the order because of this, there will be no follow-up orders.

Domestic companies that can use small molybdenum crucibles simply do not look down on companies that have just entered the industry like them.

If there is no benefit in a short time, it is very likely to be sold by the entire Chengdu city government or closed directly!

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

"Let’s leave this question alone, Mr. Xue, what are the technical conditions for these small molybdenum crucibles?" Seeing those spots that are rapidly oxidized due to workers’ sweat, Yun Fei was dark in his heart, and Zheng worry couldn’t find what to do. Ion water’s anti-oxidation technology is sold to the 754 Plant.

This is simply dozing and encountering a pillow.

As long as these products meet their technical standards, and then sell them this anti-oxidation technology, it is definitely a sure thing.

Many semi-finished products, such as wooden discs, tungsten target blanks, and molybdenum blanks produced by the fifth branch of the Seventh Five-Fourth Plant, were returned by September 1st Materials Co., Ltd. because the anti-oxidation technology failed. These materials used in electronic products, It can’t be cleaned with acid and alkali...

This technology will not sell too much, let the 754 factory give three to five million, and it is almost the same.

There are a lot of companies in China that need this kind of technology. Even if they sell ten, they can have a revenue of three to five million yuan.

This is much higher than investment!

Hundreds of percent of income.

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

Yun Fei was stunned.

Nima, it's been a few months, the production process is not mature yet?At the beginning, I provided a complete production process, even if I had three or two more times, I could master the parameter range!

"Tell me the specific data, how close is it? One percent is a little bit, and 0.1% is a little bit too!" Yun Fei's face began to become cold.

Talking about the data directly, you can understand how much the difference is!

Actually say a little bit in general!

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

"All?" Yun Fei frowned.

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

The cost of a small molybdenum crucible of about five kilograms is about 3,000 yuan, and the cost of producing NdFeB rare earth permanent magnets is about 30 yuan per kilogram!

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

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

"You mean concession to accept?"
