Chapter 289: Overkill

Chu Bole's situation is better.
He had stayed in Germany in his early years and had some connections with FAG.
When necessary, he can use some of his previous relationships in Germany to obtain some technical support from FAG to ensure his survival.
However, the Germans are also very rigid in doing things, and they pay attention to rules in everything, and this kind of support is not strong.
Unless, Hubler is willing to become FAG's foundry.
Now, Hubole is hesitant.
Do you want to become a foundry of FAG?
Becoming a foundry means that although the income is not much. But stable. There is no need to consider sales issues.
However, after becoming a foundry, I feel no passion.
He is about to become a robot and can only accept FAG's instructions.
In addition, I am afraid that the power to control the factory must be handed over. Blond foreigners will come to control the factory.
Willing?
Of course not reconciled.
Who wants to give away his own factory?
As long as there is still a ray of life, we must make great efforts. At the last moment, never give up lightly.
"What help do you want?" Wang Bu'an asked lightly.
Everyone is sensible, so there is no need to be polite.
Going directly to the topic is king.
I just want to be the president.
I want your support.
It's that simple.
Why do you support me?
Because I can help you. I can help you out of trouble. To help you thrive and develop healthily.
"It's mainly raw materials." Yuan Baoshan didn't make any obtuses either.
"Is there a list?" Wang Bu'an said.
"Have."
"Bring it to me to see."
"it is good."
Yuan Baoshan handed over the list of materials.
Wang Buyan glanced casually. Nothing special. It's totally satisfying.
Yuan Baoshan's main focus is thrust ball bearings. The hard alloy needed.
According to material specifications, it is required that the gravity per square centimeter is higher than 50 tons.
Yes, it is 50 tons.
As long as it is higher than 50 tons, it can meet the needs.
However, Wang Bu'an looked around and found that none of them was as small as 50 tons. All the hard alloys are of the 7,200 ton level.
It seems a waste to use such a high-level hard alloy to make thrust ball bearings?
100% overkill!
"What about yours? What do you need?" Wang Bu'an turned his head and looked at Zhong Dajiang.
"Here." Zhong Dajiang handed over the list.
Wang Buyan glanced casually.
Still nothing special. It's totally satisfying.
Zhong Dajiang's main product is two-way thrust angular contact ball bearings, which are also very demanding bearings. The requirements for raw materials are very high.
Not only requires resistance to heavy pressure, but also requires resistance to centrifugal force. It also requires resistance to high temperatures of 500 degrees.
High-end bearing steel is required, and the required label is very high and the cost is also high.
As with any high-end material, once it comes to cost, that is a problem.
The main problem for Zhong Dajiang is that the cost of raw materials is too high, which makes it unsustainable.
His hope is straightforward.
The price of raw materials can be reduced by half.
"The price of high-end bearing steel is more than 200,000 yuan per ton! You still need to wait in line for production." Zhong Dajiang felt helpless.
"I will provide you with bearing steel, 100,000 per ton." Wang Bu'an said.
"Can you meet the requirements?"
"of course."
Wang Buyan answered confidently.
What does it mean to meet the requirements? Is it completely surpassed your requirement standard dozens of times, OK?
It's totally overkill.
Others use it to make aero engines.
It is a bit wasteful to make bearings. However, in order to improve the quality of the product, it has no choice but to do so temporarily.
"And yours?"
"it's here."
Hubler studied needle roller bearings.
Now this year, if you want to get ahead, you must constantly research new products and constantly introduce new ones.
Or, like Wang Bu'an, he has an overwhelming advantage in quality.
However, needle roller bearings have higher requirements.
What is a needle?
Relative to its diameter, the roller is thin and long.
But the load to withstand is very large, not only requiring resistance to heavy pressure, centrifugal force, and high temperature resistance, but also very high toughness.
This requires higher raw materials.
Even very high-end bearing steel can't be satisfied.
Must be special bearing steel.
In the final analysis, the quality of the bearing is closely related to the raw material-bearing steel.
The problem now is that bearing steel either cannot meet the demanding requirements. Either it is achieved, but the cost is high. Or the output is too small to meet market demand.
What are the requirements for bearing steel?
First, we must resist fatigue. Under the action of cyclic load, the bearing is prone to fatigue damage when contacting the surface, that is, cracks and peeling appear, which is an important sign of bearing damage. Therefore, in order to further improve the service life of the bearing, the bearing steel must have a high contact fatigue strength.
Second, it must be wear-resistant. When the bearing is running, not only rolling friction occurs between the ring, rolling element and the cage, but also sliding friction occurs, so that the bearing parts are constantly worn. In order to increase the wear of bearing parts, maintain the accuracy and stability of the bearing, and extend the service life, the bearing steel should have good wear resistance.
Third, hardness. Hardness is one of the important qualities of bearing quality, and it has an indirect influence on contact fatigue strength, wear resistance, and elastic limit. The hardness of bearing steel under operating conditions must reach HRC61~65 or more. Make the bearing achieve higher contact fatigue strength and wear resistance.
Fourth, rust prevention. In order to prevent bearing parts and finished products from being corroded and rusted during processing, storage and use, it is requested that the bearing steel should have good rust resistance.
Fifth, it is easy to process. In the production process, bearing parts have to go through many cold and hot processing procedures. In order to meet the small quantity, high efficiency and high quality requirements, the bearing steel should have good processing performance. For example, cold and hot forming performance, cutting performance, hardenability, etc.
In addition to the above-mentioned basic requirements, bearing steel should also meet the requirements of proper chemical composition, average external structure, less non-metallic impurities, external appearance defects conforming to specifications, and external surface decarburization layer not exceeding the regular concentration. The last point is the most important point. Of course, the price should be reasonable. Allow bearing manufacturers to bear.
Due to the many requirements, the price of good bearing steel is very high.
Several multinational companies have either developed their own or cooperated with sophisticated steel mills. Specializing in the production of bearing steel.
The biggest weakness of our country is that the production of raw materials is temporarily unable to catch up.
In the field of bearing steel, we started relatively slowly. Even if it develops rapidly, it is asymmetrical.
Generally speaking, bearing steel is divided into six categories: high-carbon chromium bearing steel, chromium-free bearing steel, carburized bearing steel, stainless bearing steel, medium and high temperature bearing steel and antimagnetic bearing steel.
High-carbon chromium bearing steel [GCr15] is the most produced bearing steel in the world. The carbon content of Wc is about 1%, and the chromium content of Wcr is about 1.5%. Since its birth in 1901, the main components have basically not changed. With the advancement of science and technology, research work continues, and product quality continues to improve, accounting for more than 80% of the world's total bearing steel production. So if the bearing steel has no special instructions, it refers to GCr15.
The high-carbon chromium stainless bearing steel produced by Huaxia, the main steel grade is 9Cr18; the carburized bearing steel, the main steel grade is G20CrMo; the chromium bearing steel, the main steel grade is GCr15. They are relatively common types of bearing steel. However, some relatively unpopular and extreme bearing steels are not produced.
For example, the special steel for needle roller bearings required by Hubler needs to be imported from abroad. The domestic demand cannot be met.
Once the import channel is cut off, or the price is deliberately raised, he will be tragic.
Now, what he has encountered is a sharp increase in prices.
The original special steel for needle roller bearings cost about 300,000 yuan per ton. Now it has skyrocketed to 500,000 per ton.
The cost has risen so much all at once, and of course Hubler cannot bear it.
Large manufacturers may have a certain amount of inventory to survive the crisis.
A small manufacturer like him does not have any inventory.
There was no stock, so work had to be stopped.
Once work is stopped, you are burning your own blood!
"The needle roller bearing materials you need..." Wang Bu'an said to himself, "There is no suitable one..."
"Really not?" Qiu Bo couldn't help being greatly disappointed.
Zhong Dajiang and Yuan Baoshan also expressed deep sympathy.
However, there is no alternative to this.
After all, needle roller bearings require raw materials. It's really special.
Wang Bu'an is not a god.
He can't solve all the problems.
"In fact, there is no need to use special bearing steel." Wang Bu'an said lightly, "Ordinary hard alloy is enough~EbookFREE.me~ impossible." Qiu Bole asked, "Ordinary hard alloy is absolutely impossible. Used. Even if the hardness is achieved, the toughness will not be achieved."
"Isn't 900 Pascal tensile strength enough?" Wang Buan disapproved.
"900 Pa? Of course that is enough." Qiu Bole was taken aback.
"The cemented carbide I provided you. This is the one."
"Huh? Such a high parameter?"
"Yes. A little overkill, isn't it? Only 100,000 yuan per ton."
"Good, good, good."
Qiu Bole was finally relieved.
If the parameters of this hard alloy are true, he definitely made a profit.
Not only can it meet the current production needs, but it can also continuously develop new products. Develop more high-end products.
It can withstand 7,200 tons of heavy pressure, 7,200 degrees of high temperature, 720 tons of centrifugal force, 900 bar of tensile strength... it's a perfect material. If used as a bearing, it is indeed very talented. But, on the other hand, can bearings made with it also crush opponents? If it can further exert its performance, can it be made into the best needle roller bearing in the world? He can also become the world's number one needle roller bearing manufacturer?
No wonder the bearings of brands such as pterosaurs, stegosaurus, and Ryzen can take the top three in hardware quality. Dare to feel that the raw materials are too good!
"However, this kind of hard alloy is too good." Wang Bu'an showed a hint of intriguing smile, "I am afraid that your current machinery and equipment cannot be processed."
"Oh? Are you going to sell us professional machine tools?" Qiu Bole reacted immediately.
6 more today. I hope I can get more recommendation votes. Thank you.
