Chapter 391 I have to rely on my husband

In the laboratory of the Electrical Research Institute, Tang Hao picked up the soymilk machine and poured a cup of hot soymilk for Li Weidong.

Director Li, how about this soy milk! Tang Hao said.

Li Weidong picked up the cup, blew the hot air, and took a small sip. The soy milk was a little hot, but the soy taste was still very strong.

Tang Hao then introduced: According to the research and development ideas you provided, we not only put the motor on top, but also put the heating rod on top. After the motor is put on top, cleaning is much easier than before. The only disadvantage is that the soy milk The top half of the plane will be heavier.”

So, this soymilk maker can already be mass-produced? Li Weidong asked.

Tang Hao shook his head: From the design point of view, there is no problem, but I don't think it can be mass-produced now, because the quality of the blades we use is not up to standard.

Is there a problem with the blade? Li Weidong picked up the blade of the soymilk maker and began to observe it carefully.

Tang Hao said, The blades we use are relatively new at the beginning, but after a period of time, the wear and tear will be severe, and there will be more residues in the soy milk produced, which will also affect the soy milk. juice yield.”

How long are you talking about? Li Weidong asked.

Tang Hao thought for a while and then replied, According to my judgment on the deterioration of the blade, if you make soy milk twice a day, it will take less than a month, and the soy milk produced will be close to corn mush!

The technology of our soymilk machine comes from the German wall breaker, so will this happen to the German wall breaker? Li Weidong asked.

The German wall breaker is mainly aimed at fruits and cooked food. The hardness of fruit is not the same as that of soybeans. Moreover, foreigners use wall breakers to make liquid food. If it is thicker, there is no problem. Yes. But what we make is soy milk, and if it's too thick, it won't work.

Tang Hao went on to explain: The material of foreign blades is better than ours, and the hardness of the food they process is lower than most, so they are more durable.

This is because our material technology is not enough! Is there any solution? Li Weidong asked.

Tang Hao nodded: Yes, that is, run the soybeans with water for a period of time, wait for the soybeans to soften, and then put them into the soybean milk machine for processing, so that the service life of the blades will be greatly increased.

If the beans are soaked, it will take 10 hours, right? Li Weidong asked.

In summer, 10 hours should be enough.

It will be longer in winter. Tang Hao replied.

Li Weidong pouted with some dissatisfaction, and then said, That would be too troublesome. It's better not to soak the beans and process them directly.

But the beans are too hard. If you don't soak them in advance, the blades won't last long. Tang Hao said.

How about just soaking for half an hour? Li Weidong continued: For example, if you set a function, after the beans and water are put in, the processing will not start until half an hour.

Tang Hao thought for a while, and said, That should be better than direct processing, but the effect is limited, the material of the blade is not good, and it still can't hold up.

In later generations of automatic soymilk machines, some can make soymilk directly from dried soybeans without soaking beans. Others let the soybeans soak in the soymilk machine for ten or twenty minutes before starting to work.

Of course, some people like to soak the soybeans completely and then put them into a soymilk machine for processing. It’s just that this process takes a long time, 10 to 16 hours, and sometimes the beans are soaked overnight without softening.

The previous generations of soymilk machines basically needed to soak the beans before processing. If you want to drink a cup of soymilk for breakfast, you need to soak the beans the night before.

This is mainly because the technology of the blades is not up to standard and cannot directly process dry soybeans.

It is precisely because the beans need to be soaked more than ten hours in advance that the popularity of the first generation of soymilk machines is not high.

At that time, a soymilk machine sold for thousands of dollars, but the amount of soymilk produced was small, the bean dregs were too much, and the grinding was not fine, and the beans had to be soaked in advance, which made consumers reluctant to buy a soymilk machine.

Now Li Weidong has also encountered the same problem, the quality of the blade is not up to standard.

Li Weidong knows that it is not so easy to solve the problem of materials involved. Materials technology cannot be solved in a short time and requires long-term research and development and investment, which is China's weakness. It is not a new thing for China to be stuck by foreign countries because of material problems.

Li Weidong looked at the blade carefully and asked, Is this made of 304 stainless steel?

The material is 304 stainless steel. This is the most suitable material that can be found so far. Tang Hao said, showing a hesitant expression.

Tang Gong has something to say! Li Weidong said.

In fact, 304 stainless steel is not a scarce material. Our country has been able to produce it very early, but if it is subdivided, there are many types of 304 stainless steel, and each type has different manufacturing processes and performance.

Tang Hao said, picked up the blade of the soymilk machine next to him, and then said;

Even the same type of steel has different processing methods for different uses. What we need is a stainless steel blade, and the stamping technology, grinding technology and surface treatment technology required are completely different from stainless steel pipes.

304 stainless steel is a very basic stainless steel material, and it is widely used all over the world.

Various countries have different codes for 304 stainless steel. The ASTM standard code in the United States is 304, the UNS standard code is S30400, the Japanese code is SUS304, the EU code is 1.4301, and the Chinese code is 0Cr18Ni9.

According to different uses, stainless steel will also be processed by different types of plants, pipes, plates, etc., some of which are very simple to process, and some are very complicated to process.

If it is processed into a blade, the required process is more complicated. In addition to stamping, various heat treatment, cold treatment and chemical treatment of the blade surface are also a major difficulty.

At that time, China's ability to process stainless steel pipes, stainless steel clad plates, and general stainless steel small products was no problem. However, it is technically difficult to make a durable soybean milk machine blade.

Li Weidong is also not ignorant of materials science. He said, I understand everything you said. The question is where should we go to find a suitable processing method?

Tang Hao took out a list and handed it to Li Weidong: This is the parameter of the stainless steel blade. If this parameter can be met, our blade can directly make dry soybeans. But for now, the above parameter is Impossible to achieve, only as close as possible.”

Li Weidong looked at the parameters on the list, and then asked, There are many scientific research institutes in Shanghai, right? Can you make similar parameters?

This is really impossible. Tang Hao continued: Metallurgy is a heavy industry after all, and research in this area is still stronger in the north. After all, domestic heavy industry is mainly concentrated in the north. Perhaps the scientific research institutes in the capital can do it. Come up with similar parameters!

If we can't do it, we can only import it from abroad! Li Weidong sighed.

I estimate that it is difficult to import steel that can approach this coefficient. High-end steel is an important strategic material, and developed countries have strict restrictions. Even if it can be imported into China, it must be given priority to supply to military enterprises. Nothing to do with us! Tang Hao said.

It seems that I have to go to the foreign trade department to walk around. Li Weidong said with a smile.

In the foreign trade department, Li Weidong still has some connections. If he walks through the back door, he might be able to get the steel he needs.

Tang Hao opened his mouth and said, For importing high-end special steel, it may be useless to find a foreign trade department. You have to find a unit that specializes in this. After all, this is a sensitive material.

Which unit is specifically responsible for this? Li Weidong asked.

Our country has a special metallurgical import and export company, I wonder if you have heard of it? Tang Hao asked.

Metallurgy Import and Export Corporation? Li Weidong pondered a little and asked, Are you talking about the subsidiary company of Sinosteel Industry and Trade?

Tang Hao nodded: In the past, when there was the Ministry of Metallurgical Industry, Metallurgical Import and Export Corporation was under the jurisdiction of the Ministry of Metallurgical Industry. Now it seems to be merged into Sinosteel Industry and Trade.

That's even more convenient! Li Weidong laughed and said, My future husband will be in Sinosteel Industry and Trade!

...

He An'an's father, He Rong, first worked in the Ministry of Metallurgical Industry, and was later transferred to China Iron and Steel Charge Corporation as a leader. This charge company is not a unit that produces charge materials, but a unit that manages charge materials.

Later, the Metallurgical Import and Export Corporation, the Iron and Steel Charge Corporation, the International Iron and Steel Investment Corporation and the Metallurgical Processing Corporation jointly established the Iron and Steel Industry and Trade Corporation, which is the future Sinosteel Corporation. He Rong also became the leader of Sinosteel Industry and Trade.

From the names of these companies, it can be seen that Sinosteel is not a steelmaking company like Anshan Iron and Steel, Wuhan Iron and Steel and Baosteel. The company's main business is the development of mineral resources, the trade of metallurgical raw materials, and other technical services.

...

Li Weidong came to the capital, then carrying two bottles of Maotai, he went straight to He Anan's house for a meal.

After dinner, Li Weidong finally explained his intention to He Rong.

You want to import special steel? He Rong lit a cigarette and continued; Our company is indeed responsible for the import and export of special metallurgical products, but I am not in charge of this business. , what kind of special steel do you want to import, let me ask for you.

Li Weidong hurriedly handed the parameter to He Rong, and said at the same time, Actually, as long as you can get close to this parameter, of course, the closer the parameter, the better.

He Rong looked at the parameters and frowned slightly: Your requirements are quite high! General 304 stainless steel, but it can't reach this level. It seems that these parameters should be of the special military level. !

Li Weidong nodded: If it's general materials, I won't bother you!

Then wait for a while, I'll make a call and ask for you. He Rong said, stood up and walked into the study.

After a while, He Rong came out of the study with an ugly expression.

Li Weidong screamed that it was not good, but he did not ask, but waited for He Rong to take the initiative to explain.

He Rong sat back on the sofa with a livid face, and said, Stainless steel with this parameter is definitely not available now, and it is not easy to find if it is close to this parameter, but it can be found, but the key is that it is difficult to obtain. Get it.

Is our neck stuck in foreign countries again? Li Weidong asked subconsciously.

He Rong nodded: Weidong, you are not an outsider, so it's okay to tell you this. Our country has always wanted to import a special stainless steel, codenamed S39009. The parameters of this stainless steel are similar to those of the stainless steel you want. However, the procurement negotiation has never been concluded, and foreign manufacturers are worried that we will use this stainless steel in the military industry, so they have been reluctant to let go!

It's not unreasonable for foreigners to worry! Generally, this kind of special steel must be given priority to supply military enterprises. Li Weidong said with a smile.

He Rong glared at Li Weidong, thinking how can you help foreigners!

He Rong then continued: In fact, the production process of this special stainless steel is not complicated. Our Institute of Metallurgy has been conducting research, but there is a lack of some key data. Without these data, the Institute of Metallurgy can only produce a little bit. experimenting.

That is to say, foreigners refuse to sell this S39009 stainless steel to us. If we develop our own, we will be stuck on key data again? Li Weidong asked.

He Rong nodded and continued; As for this S39009 stainless steel, our internal opinions of Sinosteel Industry and Trade are not unified.

Some people think that we should continue to negotiate with foreigners and strive to buy finished products from foreign companies, which can save a lot of research and development costs and time costs, and can also meet domestic needs as soon as possible.

Some people also think that we should increase investment in research and development and take the road of self-reliance. Although the research and development time will be a long time, as long as we develop this kind of stainless steel, there is no need to worry about foreigners getting stuck!

Uncle He, what do you think? Li Weidong asked with a smile.

He Rong sighed lightly and continued: We Sinosteel Industry and Trade were merged from several units, some used to be metallurgical foreign trade, and some used to be metallurgical equipment. The point of view of the problem is of course Different. As for me, I used to manage the charge materials, and my opinion is not important on whether the S39009 stainless steel is made or bought.”

Li Weidong nodded thoughtfully, such a large enterprise with multiple units merged, internal gang formation, various entanglements of interests, and resource competition must be indispensable.

For example, those who used to do foreign trade of metallurgical materials naturally hope to buy directly from abroad, which can increase their right to speak in Sinosteel.

In the past, I was engaged in metallurgical technology and equipment services. Of course, I hoped to be able to independently develop the technology. After the technology is made, I can sell the technology and sell the equipment. Of course, the right to speak of my own faction will increase.

You guys are fighting for the right to speak, don't delay my business! Li Weidong sighed in his heart, and then asked, Has Sinosteel considered directly introducing the production technology of this S39009 stainless steel?

He Rong nodded: Of course I have considered it, but in fact, we don't need a full set of production technology, as long as we get those key data, the research institute will be able to make technological breakthroughs.

However, the cost of introducing technology also needs to be counted in scientific research investment. Moreover, in this situation, foreign companies are reluctant to buy finished stainless steel, how can they sell the technology to us!

Then this S39009 stainless steel is the technology mastered by which foreign company? Li Weidong asked again.

Nowadays, only companies in the United States, Germany and Japan have mastered the production technology of this S39009 stainless steel. There is no need to talk about the one in the United States, but when it comes to the military industry, Americans will not even sell a single screw. to us.

Germany and Japan have negotiated, but their asking prices are relatively high. The price offered by the Germans is clearly rejected. Therefore, at present, we have placed the breakthrough point in the negotiation on Japanese companies.

Although the price of Japanese companies is also high, it is not impossible to discuss, but Nissin Steel seems to be worried about the obstruction of the United States, so it has been hesitant to sell special stainless steel.

Nissin Steel? The one in Yokohama? Li Weidong asked.

Do you know this company too? He Rong asked.

Li Weidong smiled and nodded: If it is Nissin Steel, maybe I really have a way to get the key data of S39009 stainless steel!
