Fan Yang smiled: "It doesn't matter, isn't there still oil?" ”

Battle said casually: "At present, international oil prices are volatile, and China's mining efforts are relatively low, so we still have to develop together in other aspects." ”

The two chatted casually about the oil market, and Fan Yang answered them one by one.

Seeing that the conversation was almost over, Fan Yang finally inserted the topic and asked Berezovsky: "Actually, I still have some questions I want to ask Mr. for advice, if I want to import a batch of steel for automobiles, can I do it from you? Where should I consult?"

Belevsky's obvious spirit lifted, he lifted his back from the chair, he sat on the labor camp for more than ten years, finally regained his freedom, he had a deep affection for the factory, and he always wanted to do his part, and in an instant it was as if he had changed people, and said eagerly: "I can do it, what steel do you need?" I can recommend it to you. ”

Seeing him like this, Fan Yang felt that there was a play: "Wait a minute, I don't understand the steel aspect, I'll go back and get some information." ”

I returned to my seat and took the documents I had prepared.

Pull out the most faceted one and hand it to Berezovsky.

However, two minutes passed, and Berezovsky's face became darker and darker, and he muttered: "Are you building planes?"

This made Fan Yang stunned: "No, you should be joking, this is the steel imported by an automobile factory." ”

"Cars?"

"Yes. ”

Berezovsky's whole person froze in an instant.

The information is written with the steel grade, QSTE320TM.

Fan Yang can't understand it, he naturally understands it.

Based on this series of figures, what does it reflect?

The so-called steel, in the degree of foundation, is still relatively simple, nothing more than iron-making into steel, which the ancients could achieve with primitive methods.

After World War II, the steel industry in the former Soviet Union developed rapidly and has reached the leading level in the world.

However, even if it is internationally leading, there are only 8 models of ordinary carbon structural steel.

From No. 0 steel, to No. 7 steel.

No. 0 is the softest, No. 7 is the hardest.

It is then divided into three quality levels: ABC.

Relying on this No. 8 foundation steel, the former Soviet Union built a steel torrent.

On the Chinese side, after the former Soviet Union defeated the expeditionary force, it took over the old industrial base that it had operated in the northeast for decades, and the iron and steel industry slowly developed.

Technically, the Sulian technology used is still only the No. 8 steel.

It is also this No. 8 steel that has helped China to make steel and build a complete industrial system in the era.

Then Berezovsky went to prison and was isolated for 11 years.

By the time he came out, the world had completely changed.

Iron and steel technology has advanced by leaps and bounds, and since 1978, China has reached a cooperation with the new iron and steel company to establish Shanghai Baosteel Iron and Steel Plant, which has completely adopted the technology.

By 1988, China had completely abandoned the least required No. 0 steel and the rarely used No. 7 steel, and set the industrial catalogue with reference to the Western "ISO630" standard, in terms of ordinary carbon structural steel, set 4 grades.

It is no longer a simple one, two, three or four steel, but has been changed to a more complex and more accurate mechanical properties, MPA.

Q, is the Chinese abbreviation of yield strength, Mpa, is the meaning of megapascals, one megapascal is equal to 10 kilograms of pressure, 195 megapascals, it means that the steel can withstand 23.5 kilograms of tensile force per square millimeter, the standard thickness or diameter of 16 millimeters, per square meter, can withstand 1950 kilograms of weight.

In the same way, the Q215 can bear a weight of 2150 kg.

This represents the level of strength, toughness, and mechanics of the steel.

Correspondingly, the higher the strength, the higher the technical level.

The best product produced in China is the Q235, which is also the most produced by major steel mills, with an annual output of tens of millions of tons in the eighties.

But what about Kazakhstan?

Until the 90s, the No. 8 steel system of the former Sulian was still used.

Only Hama Steel can be made, and only No. 0 to No. 4 steel.

The other large steel mills could only produce iron billets and the most common steel billets, and could not make profiles at all, and only supplied raw materials for the steel mills in Eros.

After Kazakhstan became independent, Belizovsky was taken seriously, and he was invited out to preside over the industrial upgrading of Hama Steel.

Rao is an expert in this area, but after all, he has been out of society for too long, and after he came out, he broke his head and studied the steel technology in this area, trying to connect with the world.

It has also successfully completed the task and established the most advanced steel rolling mill No. 4.

But the time is too rushed, not to mention the Q235, even the Q195 is very reluctant.

It's too backward in terms of technology.

However, on the list in front of me, it is impressively listed that QSTE320TM.

Q, on behalf of yield strength, ST, is the abbreviation of German stahl steel, on behalf of the German standard, the suffix TM is the meaning of heat treatment, China's steel technology in recent years like a rocket like a rapid development, just a few years to become the world's largest steel producer, export, Kazakhstan even 195 are struggling, China has applied 320 yield strength.

This series of figures adds up to a yield strength of 320 megapascals of cold-rolled hot-formed fine-grained structural steel.

The next layer is also marked with C≤≤≤0.50,......

It represents chemical elements such as carbon, phosphorus, sulfur, silicon and so on.

To such an extent of precise control? This is enough to build airplanes, and it is actually used to build cars?

This decadence can be imagined.

Berezovsky shook his head honestly: "I may not be able to express an opinion on this." ”

Fan Yang didn't know: "Why?"

Berezovsky's old face turned red, this is too much of a bully: "Let's change the subject." ”

"Ahem, ahem. Fan Yang didn't know why he avoided it, and explained: "That's the case, we are entrusted by an automobile company to import a batch of such steel, this is the model, if it is convenient, help me take a look." ”

By the way, I handed over a photo of CA141.

Berezovsky looked familiar: "This looks like our Gas-130, right? ”

Fan Yang took the opportunity to introduce the car in detail, including its origin and production structure, and gave a complete translation.

Berezovsky watched while frequently exclaiming, as an expert in steel and power, he is also relatively clear about mechanical structures and engines, etc., and naturally understands what kind of level this is, this technology, not only Kazakhstan, but also Erros has been left far behind.

After Fan Yang finished his introduction, Berezovsky suddenly realized: "It turned out to be a cooperation with Japan." ”
