  Chapter 518 Shocking results

   "Why don't other manufacturers seize the business opportunity and develop and produce it?" After Zhao Siyan asked this question, Zhao Guoyang smiled and said.

   "Yeah, I'm just wondering about this..." Zhao Siyan said expectantly.

  Zhao Guoyang sat up straight, and said calmly: "This problem should be discussed from the composition of the drilling hoist."

"Drilling hoist is a kind of mine hoisting machinery. It is generally called a mine hoist internationally. It is mainly composed of a working mechanism, a braking system, a mechanical transmission system, a lubrication system, an observation and an operating system, and a dragging system. , control and safety protection system.”

  “Its structural composition is not complicated, but it is quite difficult to put these together and make a product.”

  Looking at Zhao Siyan's slight nod, Zhao Guoyang continued: "According to the information I know, there are currently only about six or seven domestic manufacturers capable of producing mine hoists."

   "And, among the six or seven companies, there is only one company, the Southwest Mining Machinery Equipment Factory, whose mine hoist components are produced nationwide."

  When Zhao Guoyang said this, Li Zhaohe on the side nodded and echoed: "That's right, this Southwest Mining Machinery Equipment Factory is indeed a leader in the same industry in China."

   "I once went to investigate, and their scale is much larger than our SMS company..."

   Li Zhaohe said while sighing: "It's a pity that their life is not easy now."

   "I heard that some time ago, their factory just adjusted the production structure. It seems that several projects have been cut off, and the mine hoist project may be among them!"

   "Well, the difficulty of the Southwest Mining Machinery Equipment Factory is not surprising."

  Zhao Guoyang said frankly, "Although they are a large state-owned enterprise, their production technology capabilities are second to none in China, but compared with some foreign construction machinery giants, the current gap is still quite large."

   "Before the reform and opening up, perhaps the Southwest Mining Machinery Equipment Factory could rely on its domestic advantages to get wind and rain."

   "But now the door to the introduction of foreign imported equipment has gradually opened, and joint venture products have flooded the entire mining equipment market."

   "It is not surprising that the leadership of the Southwest Mining Machinery Equipment Factory failed to recognize this point in time, change their thinking, and expand their thinking. Therefore, it has become difficult."

Glancing at the thoughtful Zhao Siyan, Zhao Guoyang waved his hand and smiled and said, "Hey, the topic is a bit far away. The reason I mentioned this Southwest Mining Machinery Equipment Factory is to explain that the manufacture of equipment such as mine hoists Difficulty."

"Just imagine, with the scientific research strength and production level of the Southwest Mining Machinery Equipment Factory, their nationally produced mine hoists are almost no longer sold, and they are about to be cut off. This can more or less explain the difficulty of manufacturing mine hoists. Bar?"

  Zhao Siyan nodded repeatedly when she heard the words: "Well, Mr. Zhao, once you say that, I understand."

   "This mine hoist is indeed not that easy to manufacture. No wonder the world market is so big. There are only a few mine hoist manufacturers in China..."

   Muttering a few words to herself, Zhao Siyan asked again: "By the way, Mr. Zhao, the manufacturing of the mine hoist is very difficult now, I have already understood it, but what is the difficulty?"

   "If our factory makes great efforts to develop this product, can it overcome such difficulties and manufacture it, and its quality can compete with other domestic joint venture mining equipment companies?"

  After Zhao Siyan asked this question, Zhao Guoyang nodded with a smile on his face and said: "Siyan, you can ask such a question, which proves that you have paid attention to the change of your role now, very good."

   "You have been able to put yourself in the position of a leader, and you can think about problems from the perspective of a leader!"

   "Yes, yes, that's really good. Although I feel very emotional, I just can't express what I feel. The chairman's summary is really incisive!" Li Zhaohe responded very cooperatively.

   Being praised by Zhao Guoyang and Li Zhaohe at the same time, Zhao Siyan's face was stained with a faint blush.

  However, she is not the kind of pretentious girl. After she blushed, she continued to look at Zhao Guoyang with expectant eyes, and she didn't understand the meaning of vowing not to give up.

  Seeing the girl's burning eyes, Zhao Guoyang spread his hands and said slowly: "Siyan, your question is a bit broad, and I will analyze it for you one by one."

   "First of all, you have to be clear about one thing. The mine hoist is not just a lifting device. It also has other uses such as detection, transportation, and establishment of connections inside and outside the mine."

   "Of course, the core part of this mining equipment is the lifting system. Let's start with this most critical core part!"

  After Zhao Guoyang's narration, not only Zhao Siyan, but even Li Zhaohe were aroused great interest.

  The eyes of the two of them stared at Zhao Guoyang momentarily, wanting to hear his thoughts and opinions as soon as possible.

  Facing the eyes of the two, Zhao Guoyang raised four fingers and said: "In terms of a complete set of products in a narrow sense, the hoisting system of a mine hoist is basically composed of four parts: the main engine, the electric control part, the motor and the gate control."

   "In our country, one of the most important reasons why we can't find a few manufacturers capable of producing mine hoists is that the development of various parts of hoisting equipment is uneven."

  Zhao Guoyang took a sip of water, moistened his throat and said, "First, let's talk about the host part."

   "At this stage, our domestically produced main engine parts, that is, the product structure, technical level, safety and reliability of parts such as the main shaft, reel and sky wheel, are still far behind the international advanced level."

   "Compared with similar foreign products, the configuration of our domestic mine hoist is too conservative, the quality is too heavy, and the optimization of structural details is not satisfactory."

   "In addition, the difference in the appearance of the product is also obvious. I believe you should understand this point, Lao Li!"

  After hearing Zhao Guoyang's words, Li Zhaohe said with deep emotion: "Yes, Chairman. The mine hoist I saw at the Southwest Mining Machinery Equipment Factory looks a bit rusty."

   "Although mining equipment must be covered in dust after use, new products still have certain requirements in terms of aesthetics."

   "But the appearance of their product is gray and unattractive, so it's hard to make people want to buy it." Li Zhaohe shook his head and sighed.

  Zhao Guoyang agreed: "Old Li, your judgment is fine. Foreigners have higher requirements on the appearance of products abroad. This is also an important reason why the products of Southwest Mining Machinery Equipment Factory have been unable to go abroad..."

  After talking about the mainframe, Zhao Guoyang continued to talk about other aspects.

   "In addition to the main engine, in terms of motors, the gap between our domestic products and the international advanced level is even more obvious."

"There is a large gap between the domestic motor's stand-alone power, external dimensions, and quality, and foreign products of the same level. The application of materials is conservative, and there is a huge gap in heat generation and cooling technology. Moreover, there is no way to obtain this gap in a short period of time. Greatly improved…”

   Zhao Guoyang's words did not mean to belittle domestic products at all, they were telling the truth.

  Because of the backwardness of the domestic material industry, there is little room for material selection for the motors of domestic mine hoists.

  Cast iron, silicon steel sheet, 45 or 40Cr round steel are not of high domestic quality.

   Among organic materials, acetal, polyester, polyurethane, polyesterimide resin, etc., and inorganic materials, China is much behind the world's advanced level.

  Under such circumstances, motor manufacturers sometimes have no choice but to use some relatively conservative materials to replace those more economical and more suitable new materials.

   After two questions in a row, Zhao Siyan's confidence in the domestic mine hoist was more or less hit.

  However, the two parts Zhao Guoyang said below made her feel as if she had poured a basin of cold water on her head.

"As for the other two parts of the lifting system, the electronic control part and the gate control part, I will discuss them together. The situation of these two parts is very similar. The backwardness of their manufacturing level is also the key factor for the failure of domestic products on the stage. .”

"Compared with the products of ABB and Siemag, which represent the international advanced level, the gate control part of the domestic mine hoist is far behind in terms of principle, structure, configuration, reliability and performance, and there is no comparison at all. .”

   "Of course, this situation is understandable. After all, our country started relatively late in gate control, less than 20 years ago, but this gap does exist..."

After talking about this long paragraph, Zhao Guoyang paused, and after they digested it, he continued: "Similar to the gate control part, compared with several companies representing the international advanced level, the electronic control of our domestic mine hoist part, the gap is equally obvious.”

   "In some key technologies, it is completely dependent on the introduction of imported technology. What is even more worrying is that this gap is still widening..."

Looking at Zhao Guoyang's dignified face, Li Zhaohe frowned, and said with a heartbroken look: "The chairman said yes! Due to the lack of high-power electronic control technology, our domestic mine hoists cannot Do not rely on imported electronic control systems."

   "According to my understanding, the current maximum power of the supporting domestic motor is 4300kW, and the test has not yet been completed. Therefore, when encountering high-power projects, the competitiveness of our domestic products is obviously insufficient..."

  Zhao Guoyang patted Li Zhaohe's shoulder lightly to show comfort.

  The next moment, he continued to speak: "At present, when purchasing large-scale hoisting equipment in China, users tend to import equipment, and even when bidding for some mining projects, people directly specify imported equipment."

   "A few days ago, I asked someone to find out about the procurement of more than 600 large-scale hoisting equipment for dozens of newly mined mines in our country throughout last year."

   "Among them, domestic equipment only accounted for less than 5%. The remaining shares were all taken up by the two industry giants, ABB and SIEMAG."

   "Such a result, described as shocking, I don't think it's too much..."
