The Nanshan Group moves quickly.

July has not passed, and the technical solutions and prototypes of wind power bearings have been produced.

Special steel is naturally provided by Nanshan Special Steel, and there is no need for special research, just find a more suitable one in the existing formula to try.

As for processing, it is not a special problem for Nanshan Group.

They can produce large-scale forging equipment, stamping equipment, and even various equipment in the factory have prototypes for debugging, trial production and other purposes.

Nowadays, it is used to produce several wind turbine bearing prototypes, and there is naturally no problem.

And these movements naturally fell in the eyes of those who have a heart.

"Mr. Fan, ThyssenKrupp does not want to reduce the price of a penny, and even said that due to the recent rise in steel prices, the price of the next batch of wind power bearings will be increased by 10%, and the possibility of further increases is not ruled out in the future."

Fang Hongmei, the head of the purchasing department of Modu Electric, was in a bad mood and reported the procurement of wind power bearings to Fan Huabo, the general manager.

As one of the top equipment companies in China, Modu Electric naturally regards wind power equipment as one of the key businesses for future development.

However, this seemingly simple device, Modu Electric found that it was not simple at all.

After years of development, it has only barely reached the target of 70% localization rate set by the ministry.

Among them, it is most difficult to see the hope of localization is the spindle bearing.

Even if it is just the situation of ThyssenKrupp and SKF manufacturers producing in China, it can be regarded as domestic, and Fang Hongmei also sees the possibility of localization.

Because these suppliers don't take this stubble at all.

Even because the development of domestic wind power in the past year has been particularly fast, the price of bearings has risen.

"What about SKF?"

"Have you asked them for a price?"

In Fan Huabo's view, Modu Electric does not necessarily have to hang on thyssenkrupp.

After all, although they are the industry leaders of wind power bearings, they are not without other bearing manufacturers to do.

"I also asked about SKF, and the price is about the same as ThyssenKrupp, and even the Timken in the United States has also found the other party to inquire, but the price is higher than that of ThyssenKrupp."

As soon as Fang Hongmei said this, Fan Huabo's face immediately became ugly.

As a large equipment manufacturer in Huaxia, when has Modu Electric been stuck like this by suppliers?

Most of the time, it's the suppliers who beg them.

If you are not very optimistic about the prospects of wind power equipment, Modu Electric will take wind power equipment as the next main product, and Fan Huabo will not want to do this kind of equipment directly.

"Can't you handle both Luozhou and ZW?"

"They also produced large bearings before, so they should have relevant experience."

Huaxia is a big bearing country, and its annual output is the first in the world.

The number of domestic bearing manufacturers is also the first in the world.

However, the technical level is still far from the first in the world.

"Wind power bearings have incomparable importance in wind power equipment, and its accuracy and stability play a vital role in the life of wind turbines."

"Now that wind power equipment is constantly being larger, this trend is becoming more and more obvious."

"The power of wind power is large, which will inevitably lead to an increase in the size of wind power bearings."

"In this way, the processing difficulty of wind power bearings will also increase exponentially, which puts forward more stringent requirements for the company's R&D and production capacity."

"So far, some of the yaw bearing ZW, which is used to connect the nacelle and the tower, can track changes in wind direction and improve power generation efficiency."

"Pitch bearings that connect the blades to the hub, thus changing the angle of the blades, can also be produced in part."

"But the spindle bearing has the largest volume, the highest precision requirements, the highest wear resistance requirements, and the highest service life requirements."

"Whether it's ZWZ or Luozhou, it can't be produced."

"There are even only a few companies in the world that can produce this kind of bearing, such as thyssenkrupp, SKF, Timken, Schaeffler, NTN and Toei Koyo, of which the first three occupy about 80% of the share."

"The domestic spindle bearings are basically made by these three manufacturers."

Fang Hongmei gave Fan Huabo a brief explanation, but this situation obviously still did not satisfy Fan Huabo.

"I remember that before the high-speed rail bearing was also controlled by several foreign bearing manufacturers such as Schaeffler and SKF, and then Nanshan Bearing broke through this technology."

"This kind of wind power bearing, Nanshan bearing can't be produced?"

As soon as Fan Huabo said this, Fang Hongmei's expression became a little tangled.

If she had asked this question a month earlier, she could have said with great certainty, "Nanshan Bearing can't do it." ”

But in the past few days, she has also seen some news released by Nanshan Group, and the other party said that she has the production capacity of wind power bearings.

Fang Hongmei expressed a certain degree of skepticism about this.

She thinks that Nanshan Bearing should have just begun to study this kind of part, and there is still a long way to go before it can really be mass-produced wind power bearings.

Of course, these are her personal guesses.

Fan Huabo is a smart person, and when he saw Fang Hongmei's expression, he knew that there should be some story in it.

However, he was not in a hurry, and did not continue to ask, but gave Fang Hongmei enough time to think.

"Mr. Fan, Nanshan Bearing has not heard that they have been engaged in research related to wind power bearings before."

"However, in recent days, the other party said that it has made a breakthrough in wind power bearing technology."

"Our purchasing department is ready to contact the other party and go to the site to see what their wind power bearings are."

"Generally speaking, it takes at least three years for spindle bearings to be produced from small batches to mass production, because it also includes the customer's verification process for product stability."

"So we still have a long way to go in the domestic substitution of high-power spindle bearings."

"SKF and ThyssenKrupp, which are traditional overseas giants, are also based on this industry experience, so they have the courage not to reduce prices or even increase prices."

Fang Hongmei obviously didn't think that Nanshan Bearing couldn't quench her thirst.

Nanshan Bearing's technology in small bearings is quite powerful, but the difficulty of large bearings and small bearings is completely different.

"Is this really that difficult?"

Fan Huabo's question should be a question in the minds of many people.

Can a bearing stump so many manufacturers in Huaxia?

However, Fang Hongmei's answer was not optimistic at all.

"Wind power bearings are large bearings, and the trend in the future is getting bigger and bigger."

"Large size means higher load, coupled with high speed and long running time, which requires a comprehensive upgrade of design, materials, cold and heat treatment processes, testing, testing, etc., and also puts forward more stringent requirements for production equipment and testing equipment."

"In addition, in addition to the wind load, the spindle bearing also has to bear the gravity load of the spindle and impeller, and the working conditions are complex."

"In the design, the bearing is required to have good impact resistance, flexible self-alignment, and excellent raceway fatigue resistance."

"In addition to the design problem, the material is also a big problem."

"This material has a high fatigue life requirement, which is closely related to the type, size and distribution of non-metallic inclusions in the raw material."

"Among them, brittle inclusions and large particle inclusions have the greatest impact on life."

"Therefore, how to further improve the cleanliness of the bearing steel, reduce the content and size of inclusions in the steel, and improve the uniformity of carbides has become the focus."

"In addition, the hardness, strength and core toughness of the spindle bearing are closely related to the selection of materials."

"In order to improve the hardness of parts and ensure the consistency of the hardness of the core surface, the material is required to have good hardenability, hardenability and process adaptability."

"These things, if you want to completely break through, it is very difficult."

Although Fang Hongmei is engaged in procurement, she is still familiar with the basic technical requirements.

Having the quality to become an engineer is what she pursued in her early years.

"In addition, although the situation in terms of process is not so serious, the manufacturing process of larger megawatt spindle bearings has increased a lot, such as cold working dimensional accuracy, heat treatment deformation, rolling element modification, raceway convexity, internal structure control of materials, and better surface treatment technology, including how to solve boundary friction and lubrication problems after the intervention of external pollutants."

"These are not projects that Luozhou and ZWZ can handle now."

Fan Huabo heard all the difficulties, and the more he listened, the more annoyed he became, and he couldn't help but say angrily: "Then are we going to let SKF and Thyssen manufacturers take care of it?" ”

"They've been profitable enough in the past, right?"

"Why are you still so greedy?"

Although Fan Huabo is not sure how much a wind power bearing costs, he knows that there is a huge difference between the cost and the selling price.

Now the price is going to rise!

There is no reason for heaven!

"As long as there are no domestic manufacturers who can produce wind power bearings, then these manufacturers can live a very comfortable life all the time."

"Can't we make a breakthrough for domestic manufacturers?"

"It's hard!"

"Did you just say that Nanshan Bearing said that they developed their own wind power bearings?"

"Yes, but that's just what they said, no one used it!"

"Nanshan Group is not the kind of unreliable enterprise, people do not know how many times the National Science and Technology Award has been won, since they dare to say that they have developed wind power bearings, it must be developed."

Regarding Fan Huabo's words, Fang Hongmei remained silent.

She naturally hopes that Nanshan Group has really developed the bearings she wants.

But based on past knowledge, she felt that this was unlikely.

"You go to contact the other party, I personally led the team to communicate with Nanshan Group, as long as they can really develop wind power bearings, all the wind power bearing orders of Modu Electric will be handed over to them in the future!"

Fan Huabo felt that he had to fight!

The key is based on his past understanding of Nanshan Group, and the probability of success is still relatively high this time.

After all, after so many years, Nanshan Group doesn't seem to have failed?

He didn't believe that the first time of the Nanshan Group would fall on his head.

Fang Hongmei naturally felt the anger of her boss, at this time, except for obediently arranging, it was inappropriate to say anything.

Soon, the delegation of Modu Electric officially set off, and Cao Yang of Nanshan Group also took Dai Hanbiao and others to receive him personally, saying that he attached great importance to it.

After all, for this period of time, for wind power bearings, although many manufacturers are inquiring about the news, some people have arranged to come to investigate.

But the level of the inspection team of Modu Electric is the highest.

And the volume of Modu Electric is also the largest.

"Mr. Cao, has Nanshan Group really developed wind power bearings?"

After a brief greeting, Fan Huabo went straight to the point, wanting to confirm the issues he was most concerned about first.

After all, that's the premise of all the following communications.

If Nanshan Group has never developed wind power bearings, Fan Huabo will definitely not have the confidence to bet all the treasure on them.

"Mr. Fan, why don't we go and visit the workshop first?"

"There are a few prototypes of wind power bearings, and then I also arranged for trial production of a part today."

Fan Huabo attaches great importance to this trip to Nanshan, and Cao Yang also attaches great importance to this breakthrough of Modu Electric.

Just like Fang Hongmei is worried, in fact, many people have doubts about whether Nanshan Bearing can produce qualified wind power bearings.

Now is the right moment to break this situation.

For Cao Yang's proposal, Fan Huabo naturally supported it with both hands and feet.

Soon, the group came to the workshop.

"Mr. Cao, I have to say that the on-site management of our workshop is very good."

"It's the same workshop, and some manufacturers look dirty and messy, but you look clean and tidy, not like a Chinese company."

Fan Huabo has also been to the site of many manufacturers, especially those who do some castings and forgings.

The working environment of these manufacturers is often relatively harsh.

Correspondingly, the scene does not look neat and clean.

After all, it's not an electronics factory, all kinds of big guys are rumbling in the workshop, and it's strange that the environment is good.

"No boasting, all the factories of our group are built towards benchmark factories."

"Next time you come over, we will visit the unmanned factory of Nanshan Robot, and it will definitely have a more different feeling."

Be humble when you should be humble, and be humble when you shouldn't.

Cao Yang is naturally more aware of this situation.

Let Modu Electric see the strength of Nanshan Group, which is not a bad thing.

"Unmanned factory?"

"I only heard about this concept overseas, but I didn't expect that Nanshan Group is also building unmanned factories."

"That's a lot of investment, isn't it?"

Fan Huabo is also the CEO of one of the top equipment giants in China, so he naturally has some knowledge.

In this way, there is no need for Cao Yang to say too many meaningless words there.

Just say a few numbers.

"According to preliminary estimates, the equipment investment of this factory is more than 500 million, which is the reason for the large number of equipment produced by our group."

"If the same factory is placed overseas, the investment will definitely exceed 1 billion yuan."

"And this factory is only the first unmanned factory of Nanshan Group, and the scale is not big or small."

"In the future, we expect to invest in larger unmanned factories, and the investment will reach billions of yuan."

Management is an art.

The more people there are, the more important management becomes.

For production plants, it is necessary to avoid workers' disobedience as much as possible.

As a capitalist, if you can replace workers with equipment, then it is definitely more convenient to manage equipment than to manage workers.

Of course, the premise is that the equipment investment is not too expensive.

Otherwise, the capitalists are not stupid.

"We are very confident in the strength of Nanshan Group, if your company can solve the problem of localization of wind power bearings, then for the development of China's wind power industry, it is definitely of great significance."

"I see that the degree of automation of the production line of your bearing workshop is also quite high, with high-precision CNC lathes, double-end grinders, manipulators, robots and other equipment, which is much higher than the coverage rate of high-precision equipment of other domestic bearing manufacturers."

While visiting the factory, Fan Huabo exchanged his views with Cao Yang.

"Not only is the production line better than other manufacturers, but our test equipment is also leading in the country."

"For example, this test bench can simulate operating conditions, monitor temperature rise, grease cleanliness, loading forces, etc., by accelerating fatigue, and finally disassemble and inspect the wear of the bearing to verify that it is the same as the design goal."

"In terms of testing equipment, we originally had phased array ultrasonic flaw detectors, roundness meters, profilometers, three-coordinate detectors and other detector equipment, which are basically no different from foreign companies."

Cao Yang personally introduced to Fan Huabo, and this treatment is definitely very high.

"Behind the wind power bearings, involving mechanics, tribology and other basic disciplines, need to consider design, processing and other practical technical issues, for reliability, service life, safety requirements are very high, to produce high-quality bearings, need to overcome these technical barriers."

"Mr. Cao, it is actually very difficult to produce wind power bearings that surpass SKF and other manufacturers."

Fan Huabo actually slowly had confidence in his heart.

Still, he voiced his concerns.

In this regard, Cao Yang naturally has a way to resolve it.

The group went straight to a laboratory where a large bearing with a length of 3 meters was being tested.

There is also a record sheet next to it that records some of the previous test data.

Fan Huabo may not be very clear about these data, but Fang Hongmei definitely feels it when he sees it.

Sure enough, after Fang Hongmei finished reading the situation in this laboratory, she immediately couldn't help but interject: "Mr. Cao, the precision of your parts is so high, what kind of heat treatment process is used?" ”

Cao Yang was waiting for Fang Hongmei's question.

So without any hesitation, he replied with a smile: "Our wind power bearings are heat treated by induction heating. ”

"The service life of induction heating and quenching bearings is 10%~20% higher than that of heating and tempering in the furnace."

"At the same time, the supporting equipment occupies a small area, saves energy, is convenient for mechanization, and more importantly, induction hardening has the advantages of small distortion of parts, no soft belt, less oxidation and decarburization, and high production efficiency."

"Based on the above advantages, compared with the traditional carburizing process, the induction hardening process has certain advantages in bearing performance, efficiency and cost."

"I believe that in the future, this process route will become a new trend in wind power bearing technology, and other companies will also adopt this scheme."

"Our Nanshan Group has never passively imitated other people's production processes and engaged in simple product localization."

"We have always integrated the spirit of innovation into the development and production of each of our products, and improved products that exceed customer expectations."

"Wind power bearings, we either don't do it, or we have to do it first."

"Whether it's SKF or Timken, if we can beat them in the field of automotive bearings, we can naturally surpass them in the field of wind power bearings."

Cao Yang's tone was full of confidence.

Nanshan Group is definitely very hated among those foreign giants.

Because it has to compete for the first place in everything, so that international giants lose their traditional technological advantages, and there is no way to make money lying down.

In the past, the high-speed rail bearing was like this, the CNC system of the machine tool was like this, and the carbon fiber was also like this.

In terms of wind power bearings, it is obvious that it will continue to be carried forward.

"Mr. Cao, if we give an order now for your company to produce a few samples, when will it come out at the earliest?"

Fan Huabo's confidence is now more and more abundant.

My trip to Nanshan this time is very meaningful.

"At most, we can send samples to the workshop of Modu Electric."

Wind power equipment is not like other products, and dozens or hundreds of sets are produced every day.

Therefore, as long as Modu Electric starts to give Nanshan Group sample orders, it basically means that the installation will begin.

It is impossible for Modu Electric to produce several pieces of equipment separately in order to detect a few parts.

This cost is too high, and the big business of Modu Electric will also be unbearable.

"Mr. Cao, then I will send you the relevant technical requirements after I go back, and then you will also provide a technical solution and a formal quotation, and then we will discuss the next step?"

Fang Hongmei interjected again at the right time.

The price hasn't been agreed yet, and she definitely doesn't want to lose the initiative.

However, although Nanshan Group wants to make a lot of money in the field of wind power bearings, it will definitely not be as black as SKF.

I didn't dry the 1 million bearings to 100,000 as soon as I came up, which would scare customers away.

"No matter what type of wind power bearing, what is the price you ask SKF or thyssenkrupp, we can be at least 30% cheaper than them."

"And our lead times will definitely be shorter than theirs."

It's not appropriate to drop the price too much.

But there is no price impact at all, and certainly not either.

That will make Modu Electric lose the power to promote the localization of bearings.

Cao Yang's current cost advantage of 30% is acceptable to all parties even if it is a relatively balanced data.

After all, this is the beginning of the production of wind power bearings by Nanshan Group, and Modu Electric does not want to push the price too hard.

When the time comes, the Nanshan Group will be scared away, and it will also be their loss.

What Cao Yang has not yet considered is the business of wind power bearings, which has virtually brought a new opportunity to Nanshan Group.
