King of Industry

Li Zhaohe himself also came from 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 these words, Li Zhaohe was quite surprised and said: Mr. Zhao, you said that this independent and complete hoist DC electric control system is not an analog speed control system?

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.

Indeed, in the early 1990s, the configuration of the domestic mechanical speed-up system was still dominated by the rotor series resistance AC speed control system with high noise and high energy consumption.

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

However, due to its many connectors, complex wiring, long debugging time, and difficult maintenance, it seriously affects the popularization and application of the thyristor DC withering system on the mine hoist.

Now that Zhao Guoyang said that he could come up with an independent complete set of hoist DC full digital electronic control system, Li Zhaohe was immediately stunned.

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

Zhao Guoyang looked at Hu Jun, who was at a loss, and said to Li Zhaohe with a smile: Old Li, this DC all-digital electronic control system I developed by myself is also an attempt. Can it pass the review of experts and successfully apply for it? Patents, it’s hard to say.”

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

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

In short, the mine hoist project is definitely feasible and has great market prospects. Once our factory receives the capital injection from Sunmoonstar, we can start working 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 chat with Director Hu about the cooperation between our factory and their Shagang Group. Zhao Guoyang turned to look at Hu Jun again.

Li Zhaohe had already guessed this point after he recognized Hu Jun just now.

Speaking of which, although Li Zhaohe and his factory have always cooperated with the local Baosteel Group in SJ City.

However, the name of Shagang Group has also been very famous in the past two years. In the entire industry, word of mouth is also quite good.

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

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

That Miss Suzanne from before was absolutely obedient to him, and nothing would go wrong.

Under such circumstances, it is not a big deal for the factory to hand over part of its business to Shagang Group.

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

Just when Li Zhaohe was thinking about the quota that Mr. Zhao might propose to Shagang, Zhao Guoyang's next words poured cold water on his head.

Lao Li, I won't hide it from you. Shagang Group has a deep cooperative relationship with a trading company under me.

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

Ah, this... After hearing this, Li Zhaohe's face turned a little pale.

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

Although Li Zhaohe is a person who distinguishes between public and private, he certainly wants to help his old classmates a little without affecting the interests of the factory.

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 my own part, I'm afraid it will make the company worse.

This...how can this be done?

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

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

He only thought that Li Zhaohe could allocate a little part of the business in the factory to himself.

Who knows, the development of things completely exceeded my expectations.

This researcher Zhao just taught the foreigner a lesson, including the tone of explaining new product development to Li Zhaohe, which made it clear that he was the talker of the Songjiang Mining Machinery Equipment Factory.

Just when Hu Jun had a little expectation for himself to win some business, Zhao Guoyang's words directly made him overjoyed.

Maybe he also sensed Li Zhaohe's embarrassment, so Zhao Guoyang touched his chin and said, Old Li, Baosteel Group, don't feel pressured, just tell the truth.

To put it bluntly, we are engaged in business, not charity. Between two raw material suppliers, we must choose the best for mutual benefit. Do you think this is the case?

Li Zhaohe looked bitter, and nodded with difficulty.

Zhao Guoyang gave a hmm and said in a deep voice: Shagang Group's price is definitely cheaper than Baosteel's. As for the quality, you will not know until the first batch of supplies is delivered by Director Hu, Lao Li.

Okay... yes, Mr. Zhao. Li Zhaohe has now basically understood Zhao Guoyang's character, and knows that he will not give in easily in business affairs, let alone challenge his authority, so he can only deal with it now. down.

On Zhao Guoyang's side, he was quite satisfied with Li Zhaohe's attitude.

He took out his cigarette case and gave them a cigarette, then turned his gaze to Hu Jun and said, By the way, Director Hu, you should have heard it just now, right? Our factory will start the Mazhong large-scale drilling hoist project soon. .”

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

I don't know if there is any product in your factory that can achieve the performance of the internationally popular Weldox700 high-strength steel plate?

Weldox700 high-strength steel plate? Hearing this, Hu Jun was startled.

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

This kind of steel plate has good cold bending and welding properties, and is mainly used for load-bearing structures that require high weight reduction.

Such as concrete pump truck structural parts, cranes and truck-mounted cranes, port cranes and handling equipment, trailers, high-temperature-resistant special fans, etc.

Seeing Hu Jun's dazed look, Zhao Guoyang slapped his forehead and laughed, Hehe, I forgot to tell you that the Chinese name of this Weldox700 high-strength plate is Weida 700 high-strength steel plate.

Hearing this, Hu Jun suddenly realized.

He nodded repeatedly and replied, I know. This Weida 700 high-strength steel plate is a relatively representative one among the international special steel plates. It is not an exaggeration to describe it as a benchmark...

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

This kind of communication, sometimes the most fearful thing is that you understand, but the other party doesn't understand.

Seeing that Hu Jun knew this special steel, Zhao Guoyang continued to explain: In the world, several indicators of this Vectra 700 are the best of the same type of steel.

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

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

I know that for domestic iron and steel companies, it is indeed not easy to achieve such an internationally leading data index for the time being. But there is one thing, I need Director Hu to give me a guarantee...

Hearing this, Hu Jun was overjoyed.

What he is most worried about right now is that the negotiation of such a large business collapsed because the product data of his own factory did not meet the requirements of this Researcher Zhao.

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

As long as the two can really cooperate deeply, the annual sales of our factory can increase by at least ten or eight percentage points. This is a solid performance...

After thinking up to this point, Hu Jun said: Researcher Zhao, tell me, I'll listen. When I go back, I will review each of your requirements one by one...

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

Internationally, there are three types of Weida 700 special steel, namely Weldox700D, Weldox700E, and Weldox700F.

The difference between these three types of steel is that according to the European 10025 standard, when the transverse impact toughness test is carried out on them, they respectively meet the low-temperature impact energy of minus 20, 40, and 60 degrees, which is not less than 27J.

My request to you, Shagang Group, is to at least guarantee the intermediate grade, that is to say, the low-temperature impact energy of minus 40 degrees, not less than 27J.

After Zhao Guoyang said this, Hu Jun's face showed embarrassment.

He faltered and said: This...Researcher Zhao, I really dare not give you an answer now. After I go back, I have to ask the people in the laboratory to make data repeatedly, so as to have a basic answer.

Zhao Guoyang waved his hand indifferently and said, Don't worry, I have seen the products of your Shagang Group. The ST690 is relatively close in terms of performance. As long as it is optimized and improved, there will be no problem.

After Zhao Guoyang finished speaking, Hu Jun showed shock on his face.

He did not expect that Zhao Guoyang could remember this ST690 after he had been to the workshop of his own factory once.

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 can be regarded as the superior performance among special steels of the same specification in China.

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

However, Zhao Guoyang also made it very clear that the drilling hoist he was going to build did not have particularly high requirements on the yield strength and tensile strength of steel, which were slightly lower than Vectra 700, which was still acceptable.

As long as the transverse impact toughness test can reach the level of Weldox700E.

Thinking of this, Hu Jun responded again and again: Success, researcher Zhao, don't worry, if the lateral impact toughness test meets the standard, there should be no problem!

Success, then please, Factory Director Hu, please test me as soon as possible after returning to see if the ST690 of your factory is really qualified. If there is no problem, then we may sign a purchase contract at any time!

Okay, okay! Hu Jun nodded again and again, agreeing wholeheartedly.
