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

After Zhao Guoyang said this, Li Zhaohe was quite surprised and said: "Mr. Zhao, do you think this independent set of DC electric control system of the elevator is not an analog speed control system, right?"

Zhao Guoyang naturally raised his hand and said, "Of course not. If so, I don't need to mention it."

Indeed, in the early 1990s, the domestic system for improving the configuration of mechanical speed-withdrawing systems was still a rotor series resistance AC speed-regulating system with high noise and high energy consumption, which dominated.

Although in 1986, several major research institutes across the country had jointly designed an analog speed regulation system, namely generator-motor DC speed regulation system

However, due to its many plug-ins, complex lines, long debugging time and difficult maintenance, it seriously affects the popularization and application of thyristor DC speed system in mine hoists.

Now Zhao Guoyang said that he could develop an independent set of DC fully digital electronic control systems for the elevator, and Li Zhaohe was immediately stunned.

It is more complicated to explain this professional issue.

Zhao Guoyang looked at Hu Jun who was a little confused next to him, and smiled and said to Li Zhaohe: "Old Li, the DC full digital electronic control system I built myself is also an attempt. It is hard to say whether it can pass the expert review and successfully apply for a patent."

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

"Ah, okay, okay!" Li Zhaohe was stunned for a moment, and could only nod and respond.

"In short, the mine hoist project is definitely feasible and has market prospects. Once our factory receives investment from Sunmoonstar, we can start moving immediately."

"Uh..." Li Zhaohe knew that Zhao Guoyang had decided, so he naturally didn't say more.

"From the following, let's talk to Director Hu about the cooperation with their Shagang Group in our factory." Zhao Guoyang turned to look at Hu Jun again.

Li Zhaohe had guessed this just now after recognizing Hu Jun.

Speaking of which, although Li Zhaohe's factory has always cooperated with Baosteel Group, a local Songjiang City.

However, the reputation of Shagang Group has also been very well-known in the past two years. In the entire industry, it has a very good reputation.

In other words, the cooperation foundation between our own factory and Shagang Group definitely exists.

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

The Miss Susanna before was absolutely obedient to him and 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.

I think Director Meng of Baosteel Group can understand his difficulties.

Just as Li Zhaohe was thinking in his mind about the amount that Mr. Zhao might have proposed to give to Shagang, Zhao Guoyang's next sentence directly poured his head and poured it on a basin of cold water.

"Old Li, I don't hide it from you. Shagang Group and a trading company under my command have in-depth cooperative relationships."

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

"Ah, this..." After hearing this, Li Zhaohe's face suddenly turned pale.

He and Director Meng, who is in charge of sales in Baosteel Group, are old classmates and have always had a good relationship with each other.

Although Li Zhaohe is a person with clear public and private affairs, he certainly wants to help a bunch of old classmates without affecting the interests of the factory.

In the past two years, Baosteel Group has been on the decline, and old classmates have not had a hard time.

If I also remove this part of my body now, it will probably make this company worse.

What should I do if I...

Compared to Li Zhaohe's anxiousness, Hu Jun was ecstatic.

In fact, when he came with Zhao Guoyang today, he didn't have much expectations.

I just thought that Li Zhaohe could just give a little part of the business in the factory to himself.

Who knew that things had completely exceeded their expectations.

Researcher Zhao just taught the foreigner a lesson, including explaining the development of new products to Li Zhaohe, which clearly shows that he is the person in charge of the Songjiang Mining Machinery Equipment Factory.

Just when Hu Jun had a little hope for him to take some business, Zhao Guoyang's words made him very happy.

Perhaps feeling Li Zhaohe's embarrassment, Zhao Guoyang touched his chin and said, "Old Li, Baosteel Group, don't be under pressure, just tell the truth."

"To put it bluntly, we are not charitable in enterprises. We must choose the best between the two raw material suppliers, which are mutually beneficial. Do you think this is the case?"

Li Zhaohe looked bitter and nodded with difficulty.

Zhao Guoyang said "um" and said in contemplation: "The price of Shagang Group is definitely cheaper than Baosteel. As for the quality, you will have to wait until Director Hu's first batch of supply before you can check it yourself."

"Okay... Mr. Zhao." Li Zhaohe has basically understood Zhao Guoyang's character now, and knows that he will not give in easily in business, nor will he challenge his authority. He can only respond at the moment.

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

After taking out the cigarette box and dispersing the two of them, he turned his eyes to Hu Jun and said, "By the way, Director Hu, you should have heard it just now, right? Our factory will start the medium and large drilling hoist project in the near future."

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

"I wonder if there is any product in your factory in this regard that can achieve the performance of the most popular Weldox700 high-strength steel plate in the internationally popular?"

"Weldox700 high-strength steel plate?" After hearing this, Hu Jun was stunned.

The Weldox700 high-strength steel plate mentioned by Zhao Guoyang is a high-strength steel plate produced by Swedish Steel Okronde Co., Ltd. (SSAB).

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

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

Seeing Hu Jun's confused look, Zhao Guoyang slapped his forehead and smiled: "Haha, I forgot to tell you that the Chinese name of this Weldox 700 high-strength steel plate is Weida 700 high-strength steel plate."

Hearing this, Hu Jun suddenly realized.

He nodded repeatedly and replied: "I know. This Vida 700 high-strength steel plate is one of the more representative special steel plates in the world. It is not an exaggeration to describe it as a benchmark..."

When Zhao Guoyang saw that he had heard of it, he felt relieved.

Sometimes the most feared thing about this kind of communication is that you understand it yourself, but the other party doesn’t.

Seeing that Hu Jun knew about this special steel, Zhao Guoyang continued to explain: "The several indicators of this Vida 700 internationally are all the best among the same type of steel."

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

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

"I know, for domestic steel companies, it is indeed not easy to achieve such internationally leading data indicators for the time being. But one thing is that I need Director Hu, you guarantee me..."

Hearing this, Hu Jun's face was filled with joy.

What he was most worried about at this moment was that the product data of his own factory did not meet the requirements of this researcher Zhao, and the negotiations on such a large amount of business collapsed.

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

As long as the two companies can truly cooperate in depth, their annual sales in their factories can increase by at least ten or eight percentage points, which is a solid performance...

Thinking about this, Hu Jun started to speak, "Researcher Zhao, I'll listen. When you go back, you will review one by one according to your request..."

Zhao Guoyang smiled slightly and said slowly: "Well, since that's the case, I won't be polite to Director Hu."

"Internationally, one is a three-part model of Weida 700 special steel, namely Weldox700D, Weldox700E, and Weldox700F."

"The difference between these three types of steel is that when the lateral impact toughness test is carried out according to the European 10025 standard, the impact force of low temperature of minus 20, 40, and 60 degrees is not less than 27J."

"My requirement for your Shagang Group is to at least ensure the intermediate level, that is, the low-temperature impact power of minus 40 degrees Celsius is no less than 27J."

After Zhao Guoyang said this, Hu Jun's face showed a look of dismay.

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

Zhao Guoyang waved his hand disregardly and said, "Don't worry, I have seen your Shagang Group's products. The performance of the ST690 is relatively close. As long as you optimize and improve it well, there will be no big problem."

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

He didn't expect that Zhao Guoyang would go to the workshop of his factory once and remember that there was this "ST690".

"ST690" is a special steel produced by Shagang Group. Its yield strength is not less than 690MPa and its tensile strength is between 750-900MPa. It is considered to be among the same specifications of domestic special steels with relatively superior performance.

Of course, there is definitely a certain gap compared to the imported Vida 700.

However, Zhao Guoyang said it very clearly. The drilling hoist he was going to build did not require particularly high yield strength and tensile strength of steel, which was slightly lower than that of Vida 700, which was acceptable.

As long as the lateral impact toughness test is tested, it can reach the Weldox700E level.

Thinking of this, Hu Jun responded repeatedly: "Yes, Researcher Zhao, don't worry, if the lateral impact toughness test is met, it should be fine!"

"As long, then please ask Director Hu to test it as soon as possible after he goes 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!"
