Li Zhaohe himself is also a technical background, although he was later promoted to a management position and became a leader, but he is still very proficient in the technology of mining equipment.

After Zhao Guoyang said this, Li Zhaohe was quite surprised and said: "Mr. Zhao, you said that this independent complete set of hoist DC electronic control system is not an analog speed regulation system, right?"

Zhao Guoyang raised his hand as a matter of course and said: "Of course not, if it is, I don't need to mention it specifically." ”

Indeed, in the early nineties, the configuration of the domestic mechanical withering speed system was still the rotor string resistance AC speed regulation system with high noise and high energy consumption, which occupied a dominant position.

Although in 1986, several major research institutes in the country have jointly designed an analog speed regulation system, that is, a generator-motor DC speed regulation system

However, due to its large number of plug-in parts, complex circuits, long commissioning time and difficult maintenance, it seriously affects the popularization and application of thyristor DC withering speed system in mine hoist.

Now Zhao Guoyang said that he was able to make an independent complete set of hoist DC all-digital electronic control system, and Li Zhaohe was immediately stunned.

In this professional issue, it is more complicated to explain.

Zhao Guoyang looked at Hu Jun, who was a little dazed next to him, and said to Li Zhaohe with a smile: "Lao Li, the DC all-digital electronic control system I built myself is also an attempt, and it is difficult to say whether it can pass the review of experts and successfully apply for a patent." ”

"So let's not talk about that today......"

"Ah, good, good!" Li Zhaohe was stunned for a moment, and could only nod in response.

"In short, the mine hoist project is definitely feasible and has a promising market prospect. As soon as we get the capital injection from Sunmoonstar, we can start moving immediately. ”

"Uh......" Li Zhaohe knew that Zhao Guoyang had made up his mind, so naturally he didn't say anything more.

"From below, let's talk to Director Hu about the cooperation between our factory and their shagang group. Zhao Guoyang turned his head to look at Hu Jun again.

For this point, Li Zhaohe had already guessed it after recognizing Hu Jun just now.

Speaking of which, Li Zhao and their factory have always cooperated with the local Baosteel Group in Songjiang City.

But the name of Shagang Group has also been very loud in the past two years. In the entire industry, the reputation is also quite good.

In other words, the basis for cooperation between its own factory and Shagang Group definitely exists.

Moreover, Li Zhaohe also saw that his own Mr. Zhao was actually the actual manager of the new factory after its establishment.

The previous Miss Suzanne was absolutely obedient to him, and she would not make any mistakes.

Under such circumstances, it is not a big deal for the factory to take out part of the business and give it to Shagang Group.

Come to think of it, Director Meng of Baosteel Group can also understand his own hardships.

Just when Li Zhaohe was secretly thinking about the quota that Mr. Zhao might propose to give Shagang, Zhao Guoyang's next sentence directly poured a basin of cold water on his head.

"Lao Li, I won't hide it from you. Shagang Group and one of my trading companies have a deep cooperative relationship. ”

"After the matter of Sunmoonstar's shareholding in the past two days is decided, the business of our new factory will be completely tilted towards Mr. Hu and his side......

"Ah, this ......" Hearing this, Li Zhaohe's face suddenly turned a little pale.

He and Mr. Meng, the director of Baosteel Group in charge of sales, are old classmates, and they have always had a good relationship with each other.

Although Li Zhaohe is a person who has a clear distinction between public and private, but without affecting the interests of the factory, of course he also wants to help his old classmates a little.

In the past two years, Baosteel Group has been going downhill, and the life of old classmates is not easy.

Now, if I also withdraw this part, I am afraid that it will make this company even worse.

This...... What can I do?

Compared with Li Zhaohe's impatience, Hu Jun was ecstatic.

In fact, when he followed Zhao Guoyang over today, he didn't have much expectations.

Just thinking that Li Zhaohe can give a little bit of the business in the factory to himself.

Who knows, things turned out completely beyond their expectations.

This researcher Zhao just taught the foreigner a lesson, including the tone of explaining the development of new products to Li Zhaohe, making it clear that he is the person who speaks of this Songjiang Mining Machinery and Equipment Factory.

Just when Hu Jun was a little looking forward to winning some business, Zhao Guoyang's words directly made him happy.

may also feel Li Zhaohe's embarrassment, Zhao Guoyang touched his chin and said: "Lao Li, over there in Baosteel Group, you don't have pressure, just tell the truth." ”

"To put it bluntly, we are engaged in business, not charity, between the two raw material suppliers, it must be a merit-based choice and mutual benefit. Isn't that the reason, you say?"

Li Zhaohe's face was bitter, and he nodded with difficulty.

Zhao Guoyang said "um", and said in a deep voice: "On the side of Shagang Group, the price must be cheaper than Baosteel, as for the quality, it will be only after the first batch of supplies from Director Hu, Lao Li, you will only know it in person." ”

"Good...... of, Mr. Zhao. Li Zhaohe now basically understands Zhao Guoyang's character, and knows that he will not give in easily in official affairs, let alone let people challenge his authority, so he can only respond at the moment.

Zhao Guoyang's side is still quite satisfied with Li Zhaohe's attitude.

He took out his cigarette case, and after giving the two of them a cigarette, his eyes turned to Hu Jun and said: "By the way, Director Hu, you should have heard it just now, right? ”

"This kind of large-scale construction machinery and equipment has very high strength requirements for special steel. ”

"I don't know if there is any product in your factory in this regard that can reach the performance of the internationally popular ELDOX700 high-strength steel plate?"

"ELDOX700 high-strength steel plate?" Hearing this, Hu Jun was stunned.

The eldox700 high-strength steel plate mentioned by Zhao Guoyang is a high-strength steel plate produced by the Swedish steel company Oklund Ltd. (SSAB).

This kind of steel plate has good cold bending and welding properties, and is mainly used in load-bearing structures with high requirements for reducing dead weight.

For example, concrete pump truck structural parts, cranes and truck-mounted cranes, port cranes and loading and unloading equipment, trailers, high-temperature resistant special fans, etc.

Seeing Hu Jun's somewhat dazed look, Zhao Guoyang slapped his head and smiled: "Hehe, I forgot to tell you that the Chinese name of this eldox700 high-strength plate is Weida 700 high-strength steel plate." ”

Hearing this, Hu Jun suddenly came to his senses.

He nodded again and again, "I know, I know." This Weida 700 high-strength steel plate is one of the more representative special steel plates in the world, and it is not an exaggeration to even describe it as a benchmark......

Zhao Guoyang saw that he had heard of it, so he was relieved.

In this kind of communication, sometimes the most feared thing is that you understand, but the other party doesn't understand.

Seeing that Hu Jun knew about this special steel, Zhao Guoyang continued to explain: "Several indicators of this Weida 700 in the world are the best in the same type of steel. ”

"For example, the yield strength is not less than 700MPa, the tensile strength is between 780-930Mpa, and the elongation is not less than 14%; Carbon equivalent ...... of CEV"

Seeing that Hu Jun's face gradually showed a dignified look, Zhao Guoyang knew that the current quality of special steel in their factory might be a little difficult to achieve such data.

"I know that it is not easy for domestic steel companies to achieve such international leading data indicators for the time being. But there is one thing, I need to be assured by Director Hu......"

Hearing this, Hu Jun's face was overjoyed.

What he was most worried about at this time was that because the product data of his own factory did not meet the requirements of this researcher Zhao, such a big deal would be collapsed.

In fact, Hu Jun's understanding of Songjiang Mining Machinery and Equipment Factory.

As long as the two can really cooperate deeply, the annual sales volume of their own factories can increase by at least ten or eight percentage points, which is a thick and solid performance......

After thinking about this, Hu Jun opened his voice and said, "Researcher Zhao, you speak, I listen." When I go back, I will review the ...... one by one according to the requirements you put forward."

Zhao Guoyang snorted slightly, and said slowly: "Well, in that case, I won't be polite to you with Director Hu." ”

"In the world, Weida 700 special steel, one is three sub-models, namely eldox700D, eldox700E, eldox700F. ”

"The difference between these three types of steel is that in accordance with the European 10025 standard, when the transverse impact toughness test is carried out, the impact energy at low temperatures of minus 20, 40 and 60 degrees is not less than 27J. ”

"My requirement for your shagang group is to ensure at least the middle grade, that is to say, the low-temperature impact energy of minus 40 degrees is not less than 27J. ”

After Zhao Guoyang's words came out, Hu Jun's face showed embarrassment.

He hesitantly said, "This ...... Researcher Zhao, I really don't dare to give you an answer right now. After you go back, ask the people in the laboratory to make the data repeatedly to have a basic answer. ”

Zhao Guoyang waved his hand disapprovingly and said: "Don't worry, I have seen the products of your Shagang Group, just that ST690, the performance is relatively close, as long as it is optimized and improved, there is no big problem." ”

After Zhao Guoyang finished speaking, Hu Jun's face showed a look of shock.

He didn't expect that Zhao Guoyang had been to the workshop of his own factory once, and he would be able to remember this "ST690".

"ST690" is a special steel produced by Shagang Group, with a yield strength of not less than 690MPa and a tensile strength of 750-900MPa.

Of course, compared with the imported Weida 700, there must still be a certain gap.

However, Zhao Guoyang also made it very clear that the drilling hoist he wants to build does not have particularly high requirements for the yield strength and tensile strength of the steel, which is slightly lower than that of Weida 700, which is still acceptable.

As long as the lateral impact toughness test can reach the level of eldox700E.

Thinking of this, Hu Jun replied again and again: "Cheng, Researcher Zhao, don't worry, if the lateral impact toughness test alone meets the standard, there should be no problem!"

"Cheng, then please ask Director Hu to test it for me as soon as possible after I go back, to see if your factory's ST690 is really qualified, if there is no problem, then we may sign a procurement contract at any time!"

"Okay, good!" Hu Jun nodded again and again, and agreed with his mouth.
