"Why don't other manufacturers seize business opportunities, R&D and production" After seeing Zhao Siyan ask this question, Zhao Guoyang said with a smile.
"Yes, I'm just curious about this," Zhao Siyan said with a look of hope.
Zhao Guoyang sat up straight and said calmly: "This question should be discussed from the composition of the drilling hoist. ” "Drilling hoist is a kind of mine hoisting machinery, generally known as mine hoist in the world, which is mainly composed of working mechanism, braking system, mechanical transmission system, lubrication system, observation and operating system, and dragging, control and safety protection system."
"Its structure is not complicated, but it is not easy to put these together and make a product."
Looking at Zhao Siyan bowing slightly, Zhao Guoyang continued: "According to the information I know, there are currently about six or seven domestic manufacturers capable of producing mine hoists. ” "And, among these six or seven, there is only one company, that is, the Southwest Mining Machinery and Equipment Factory, and this one's mine hoist parts are produced in the country."
When Zhao Guoyang said this, Li Zhaohe on the side nodded again and again and agreed: "That's right, this Southwest Mining Machinery and Equipment Factory is indeed a leader in the same industry in China." ” "I once went to inspect them, and their scale is much larger than our SS company."
Li Zhaohe sighed as he spoke: "But unfortunately, their lives are not easy now." ” "I heard that some time ago, their factory just carried out the adjustment of production structure, and it seems that several projects have been cut off, and the mine hoist project may also be among them."
"Well, it's not strange that the Southwest Mining Machinery and Equipment Factory is difficult."
Zhao Guoyang said calmly, "Although they are large state-owned enterprises, 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 and Equipment Factory could rely on its own advantages in the country, to get the 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 Southwest Mining Machinery and Equipment Factory has not been able to understand this clearly, change their thinking and expand their thinking in time, so it has become difficult."
Glancing at the thoughtful Zhao Siyan, Zhao Guoyang waved his hand and smiled: "Hey, the topic is a bit far-fetched."
The reason why I mention this Southwest Mining Machinery and Equipment Factory is to explain the difficulty of manufacturing this equipment of mine hoist. ” "Imagine, with the scientific research strength and production level of the Southwest Mining Machinery and Equipment Factory, their national mine hoist has been sold quickly, and it is almost cut off, which can more or less explain the difficulty of manufacturing the mine hoist."
When Zhao Siyan heard this, she nodded again and again: "Well, Zhao Dong, as soon as you say that, I understand." ” "This mine hoist is indeed not so easy to manufacture, no wonder the world market is so large, there are only a few domestic mine hoist manufacturers" Muttering a few words, Zhao Siyan asked again: "By the way, Zhao Dong, it is difficult to manufacture the mine hoist now, I already know it, but what is the difficulty of it?"
"If our factory makes great efforts to develop this product, can we overcome such difficulties and manufacture it, and its quality can also compete with other joint venture mining equipment companies in China?"
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 now paid attention to the change of your role, which is very good." ” "You've been able to put yourself in the position of a leader, and you've been able to think from an eader's point of view."
"Yes, yes, yes, it's really good, although I am very emotional in my heart, but I can't say what I feel, the chairman's summary is really incisive" Li Zhaohe responded very cooperatively. was praised by Zhao Guoyang and Li Zhaohe at the same time, and Zhao Siyan's face was dyed with a faint flush.
However, she is not the kind of pretentious girl, after the slight redness, she continued to look at Zhao Guoyang with expectant eyes, and she had the meaning of not giving up if she didn't understand.
Looking at this girl's burning eyes, Zhao Guoyang spread out his hands and said slowly: "Siyan, your question is a bit broad, I'll analyze it for you one by one." ” "First of all, you have to understand that the mine hoist is not just a lifting device, it also has other uses such as detection, transportation, and establishing 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 remarks, not only Zhao Siyan, but even Li Zhaohe was greatly interested.
The eyes of the two stared at Zhao Guoyang for a moment, wanting to hear his thoughts and opinions quickly.
Facing the eyes of the two, Zhao Guoyang raised four fingers and said: "From the narrow sense of the product set, the hoist system of the mine hoist is basically composed of four parts: the main engine part, the electronic control part, the motor and the gate control. ” "In our country, the reason why we can't find a few manufacturers with the ability to produce mine hoists, one of the most important factors is that the development of all parts of the hoisting equipment is uneven."
Zhao Guoyang took a sip of water, moistened his throat and said, "First of all, let's talk about the host part." ” "At this stage, the product structure, technical level, safety and reliability of our domestic main engine part, that is, the spindle, reel and wheel and other parts, is still very far from the international advanced level."
"Compared with similar foreign products, the configuration of our domestic mine hoist is too conservative, the quality is 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 Lao Li should know something."
Hearing Zhao Guoyang's words, Li Zhaohe was deeply touched and said, "Yes, chairman."
The mine hoist I saw in the Southwest Mining Machinery and Equipment Factory looked a little dirty. ” "Although the mining equipment must be covered in dust after use, there are still certain requirements for the aesthetics of new products."
"But the appearance of their product is not gray, and its appearance is not good, and it is difficult for people to have a desire to buy."
Li Zhaohe shook his head and sighed.
Zhao Guoyang agreed: "Lao Li, your judgment is no problem, in foreign countries, foreigners have higher requirements for the appearance of products."
This is also an important reason why the products of Southwest Mining Machinery and Equipment Factory have been unable to go abroad for a long time."
After talking about the host part, 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 single power, dimensions, and quality of domestic motors and foreign products of the same level, and the application of materials is conservative, and there is a huge gap in heating and cooling technology, and this gap is not possible to be greatly improved in a short period of time."
Zhao Guoyang's words did not mean to belittle domestic products at all, and he was completely telling the truth.
Because of the backwardness of the domestic material industry, the motor of the domestic mine hoist has little room in the selection of materials.
Cast iron, silicon steel sheets, 45 or 40cr round steel, these steels, the quality of domestic production is not high.
Among the organic materials, acetal, polyurethane, polyurethane, polyesterimide resin and inorganic materials are much behind the world's advanced level in China.
In such a situation, motor manufacturers sometimes have no choice but to use some relatively conservative materials to replace those more economical and more suitable new materials.
After talking about two questions in a row, Zhao Siyan's confidence in the domestic mine hoist was more or less hit.
However, the two parts that Zhao Guoyang said below made her feel like 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 talk about it together.

The situation of these two parts is very similar, and the backwardness of its manufacturing level is also a key factor that domestic products have not been able to put on the table. ” "At present, the gate control part of the domestic mine hoist, in terms of principle, structure, configuration, reliability and performance, compared with the products of ABB and Simage, which represent the international advanced level, is far behind, and there is no comparison at all."
Of course, this is understandable.
After all, our country started late in terms of gate control, less than 20 years, but this gap does exist."
After talking about this large paragraph, Zhao Guoyang paused, and after they digested it, he said: "Similar to the gate control part, compared with several companies that represent the international advanced level, the electronic control part of our domestic mine hoist, the gap is also obvious. ” "In some key technologies, it is completely dependent on the introduction of imported technology, and what is even more worrying is that this gap is still expanding" Looking at Zhao Guoyang's solemn face, Li Zhaohe frowned and said with a sad look: "What the chairman said is that due to the lack of high-power electronic control technology, our domestic mine hoist has to rely on imported electronic control systems. ” "As far as I know, the current maximum single power of the domestic motor is 4300kw, and the test has not yet been completed, so the competitiveness of our domestic products is obviously insufficient when encountering high-power projects."
Zhao Guoyang gently patted Li Zhaohe's shoulder to show comfort.
The next moment, he continued to speak: "At present, in the procurement of large-scale lifting equipment in China, users often tend to import equipment, and even when bidding for some mining projects, people directly designate imported equipment. ” "A few days ago, I asked someone to learn about the purchase of more than 600 sets of large-scale lifting equipment from dozens of newly mined mines in our country throughout last year."
"Among them, domestic equipment accounts for less than 5.
The rest of the share is all covered by the two industry giants, ABB and SEMAG. ” "I don't think it's too much to describe this result as shocking":
