Chapter 825 Grab!
Even though this booth looks boring, there are so many people surrounding it. The real platform for this exhibition is the Metallurgical Technology Exchange Conference of the 17th Ministry of Machine Building. Naturally, most of the visitors are related to metallurgy. It is not surprising that there are more people at the booth of the 17th Ministry of Machine Building, as it is a suitable place for their profession.

The reason for the large number of people is simple: the various materials on display here have very good performance.

It's not very good, but it's somewhat good. For materials with similar uses and the same specifications, the price is lower than those sold outside. For materials with the same price, the specification numbers will be a little higher.

Of course, there are also some that some developing countries and even economic aid countries cannot produce on their own, and it is even difficult to buy them.

The Russians' material technology is actually average, so it is normal for the brothers who follow them to have some difficulties in this regard. This is a semi-open secret.

As a movie fan said, "If you follow the crows, you will go hungry nine times out of three days." In some areas, following the Russians is a bit like this.

It's not that it doesn't give. The 10 billion yuan subsidy in this regard was really given, but there are many things that it really doesn't have.

The Russian metallurgical experts know why those agricultural machinery sellers over there, without anything else, have boosted their sales just by piling up materials.

They really dare to do it! Seeing the prices of these materials, which are only a little bit better, the reason why they dare to do it is very clear. The prices of these materials are not high. Some low-grade materials are not even seen. They are not exhibited, sold, or available.

"As for the Davari family, I'm sure they still have a lot of technology that has not been made public." An old Russian metallurgical technician said to his colleagues.

"Don't be too greedy, my comrade. We have already reaped enough."

"I know, but I still don't understand how they developed so quickly."

The Russians didn't suspect that we were falsifying goods at the exhibition. After all, these things were to be sold, and if they were fake, we wouldn't even be able to deliver the goods.

"They have stood up for more than ten years, and they have not been idle, my Davari. And I think you know how hard-working and smart they are." The old Russian metallurgical expert is older, has seen more, and thinks more thoroughly.

As they walked forward, they said that they also had most of these materials, although they were more expensive, but there was no need to import them from the southern comrades. However, some special materials such as tungsten-molybdenum, tungsten-silver, tungsten-copper, tellurium-mercury-cadmium, and 59X special alloy would not appear at this exhibition at all.

However, this kind of special materials is not completely unavailable.

"Monocrystalline silicon? It has a purity of 6 nines! And the diameter reaches 9 centimeters!" Monocrystalline silicon is not a metal material, and these people are not actually familiar with it, but their basic properties are relatively clear.

"No wonder their integrated circuit technology has made such rapid progress. This is the most basic integrated circuit material."

"Should we notify our comrades who are doing relevant work in China and import a batch?"

"Notify them, but it may not be very meaningful. The basic materials for integrated circuit technology are only the most basic. Other technical requirements are also very high. I don't know if we have them, but what I know is that they are more interested in electron tubes. And maybe our comrades have single crystal silicon of this specification."

As they walked and talked, one of the craftsmen, Mr. Davari, suddenly shouted in surprise: "Thermocouple! Thermocouple!"

His performance puzzled his colleagues. What was so exciting about thermocouples? Who here didn't see dozens of them every day?

But when they looked in the direction of the colleague's hand, they understood why he was so excited.

There is nothing else, just one thing, on the label of this thermocouple, there is a big line of words, which are translated into Maozi, Gaul and English in addition to Chinese.

"Type B thermocouple, stable working temperature 0~1600℃, short-term working temperature 0~1800℃."

As for the real name of Platinum Rhodium 30-Platinum Rhodium 6, it is not listed above.

How much? The old man couldn't even believe his eyes and looked again carefully.

The reason why the Type B thermocouple was also put up was because Gao Zhendong knew that this thing originally appeared in the 60s, and there was no point in keeping it secret any longer, so it was better to just release it directly, sell it at a higher price and reap the profits later.

It's made of rubies on the outside and platinum and rhodium on the inside. It's an exclusive technology. We would be letting down the organization and the people if we didn't sell it at a higher price.

But what was developed in the 60s is different from what the Russians have now.

"I want this! I believe that the comrades working on rockets, airplanes, and engines also need this! Mr. Davari, go find their staff and we'll order as many as you can get."

He did not even care about the extremely high price compared to the EU-2 thermocouple. The importance of high-temperature stable online measurement to them is self-evident. Although it is only 2℃ higher than the 1300℃ of the EU-300, this 300℃ is a hurdle that they cannot cross. After all, in terms of proportion, this is an increase of almost 25%, which is very high.

Moreover, the 2℃ of the EU-1300 type is only a short-term temperature. The long-term working temperature is only 1000℃, which is even more amazing.

EU-2, the old graduation number of K-type thermocouple. The Russians are experienced. Planning is something that cannot be escaped anywhere. Products of this specification are definitely not available in large quantities. These days, good things have to be snatched.

He even regretted lingering in the front exhibition area yesterday. He wondered how much was left.
But they were lucky. This product was too high-end and had limited uses. Compared with the EU-2 model, it was extremely expensive, and not many countries could use or afford it.

Fortunately, Professor Li Wei has not come here yet. He went to the "Chamber of Commerce" yesterday to draft an agency request. Although he is not in business, as a senior technician, he must support the work of his own people.

Watching our staff operating the computer and writing down their names and order quantities on the registration form, the Russian metallurgical expert smiled happily.

——Product name: Type B thermocouple, remaining quota: 0.

The writing on the computer screen was very clear. In order to demonstrate our technological strength, Gao Zhendong requested that even those who sold window decorations be equipped with a computer with a database system, if for no other reason than to highlight two words - domineering.

At this time, his colleague came over and pulled him.

"Davali, there's something else here that I think you should see."

As the leader of this group of metallurgical technicians, he needs to be involved in any discovery.

"What is it?" he asked as he followed the man.

"A thermocouple, similar to the EU-2 type."

"It's still a thermocouple? What's so special about it?" He did not say anything disparaging like "What's so exciting about the EU-2 thermocouple?" He now knew very well that Comrade Nan Fang dared to put something at this exhibition and that could interest his colleagues, so it must be unique.

"A new model that solves some of the problems of the EU-2 thermocouple, and the price is about the same as the EU-2." Sure enough, his colleague's answer aroused his great interest.

A thermocouple that is similar in price to the EU-2 type but more complete?
EU-2 thermocouples are cheap, but their disadvantages are also obvious. Thermoelectric potential has poor high-temperature stability, and the thermoelectric potential cycle stability is poor in the two ranges of 250~550℃ and around 800℃. It also has poor radiation resistance, which makes it very difficult to use in special environments and under high requirements.

I just don’t know what problems this new type of thermocouple solves for the EU-2 type.

When he saw the label for this new thermocouple, he was as excited as when he saw the Type B thermocouple.

The Type N thermocouple, one of the most significant advances in base metal thermocouples, deserves his reaction.

The introduction on the sign only explains one problem. This new temperature measuring equipment, called N-type thermocouple by comrades in the south, has the same temperature measurement range as EU-2 type, but to a certain extent solves the problems of poor high-temperature thermal stability of EU-2 type thermocouple and insufficient cyclic stability in some intervals. It is also resistant to radiation!
Although the price was nearly twice as high as the EU-2 model, he felt that his colleague's words were very good. This thing was not much more expensive than the EU-2 model, and was even cheaper.

As a top technical expert, he understands better than anyone that high-tech products are worth what you pay for.

He didn't even have time to exclaim or comment, but turned around and ran!

This thing is cheap and has a much wider range of uses than the Type B thermocouple we saw earlier. There are still a lot of those things left, but this thing is harder to say.

When he ran to the staff, there was a person in front of him registering his intended order.

As soon as the man looked at his appearance, the Russian metallurgical expert who had lived for decades knew that he was a Gaul. He could smell the Gallic scent on him even across the Yenisei River.

Hmm? Gauls? The old Russian suddenly felt something was wrong.

When he stretched his head to look at the computer screen in front of our staff, the glowing characters on the screen confirmed his guess.

——Product name: N-type thermocouple, remaining quota: 0.

"No! This is not fair! You should ensure that every customer gets the products they want to buy!" At this time, the old Russian had completely forgotten the happy smile he had just had when he saw that the remaining quota of type B thermocouples was 0.

"Hello, comrade. All our products are open for ordering. We cannot control the order quantity of each customer. If you are interested, you can register with me. When the new quota is released, we will notify you first."

Didn't you manage to get by without these things? Is this thing so urgent?

For the Russians, this is not a matter of urgency or not. The fact is that compared to computers, this thing is easier to copy. The sooner they get it, perhaps they can use the cheap products they produce earlier.
