Chapter 68 Bearing Steel

Although Zhang Yi was very happy in his heart, he was also very helpless towards Xiao Hua's behavior. After all, in the entire Qicaishi Machinery Factory, only Xiao Hua would jump in like this without knocking on the door. Now Xiaohua is in the system employment period.

But because Zhang Yi's mother recognized Xiaohua as her goddaughter, Xiaohua began to think about emigrating. You must know that this is not immigration between people from various countries on the earth, but immigration between universes.

"Mr. Zhang, I'll go out first!" After speaking, Wang Hong walked out without waiting for Zhang Yi to answer.

"Xiaohua! Let's go and see your experimental results!" Zhang Yi stood up, pulled Xiaohua up and walked out of the office.

Since the temporary metallurgical laboratory where Xiaohua and the others are located is not far from Zhang Yi's office, Zhang Yi and the others soon came to the laboratory.

This laboratory was actually originally transformed from an office.Although this factory building has more than 1 square meters.However, when it was designed, there was no special room for the laboratory.

In a small town like Xianxian County, there are no high-end enterprises at all. Even if there were, they would not take a fancy to such a factory building. So when the factory building was built, the county thought it was unnecessary, so it didn't A dedicated experimental site for the laboratory.

After coming to the laboratory, there are already many people in the laboratory, and even Wang Hong who just came out of the office is already here.

"Hurry up and take a look at the data of the new type of bearing steel. They all have those characteristics." Zhang Yi said to Xiao Hua immediately after entering the laboratory.

"Okay, brother! I'll get it for you right away!" As she said that, Xiao Hua brought a stack of papers to the desk next to the laboratory.

Zhang Yi took the papers handed over by Xiao Hua and looked at them. This stack of papers was the experimental data of this bearing steel. The first thing that caught his eye was the melting point of this new bearing steel.

The melting point of this new type of bearing steel is very high. It can be said that it has surpassed most of the steel used in bearings today. The melting point has reached 1880 degrees. After becoming a bearing, it can operate stably at temperatures up to about 1300 degrees.

This shocked Zhang Yi. You must know that ordinary high-temperature-resistant bearings can withstand a maximum temperature of about 6-800 degrees, but the bearings made of this steel can run stably at a temperature of 1300 degrees.

This has completely surpassed the performance of all high-temperature-resistant bearing steels in the world. Of course, this is only theoretical data. After all, this bearing steel has just been developed and has not yet been tested, so this data may not be very good. precise.

But just such a data has already made Zhang Yi very excited. Such a high-temperature-resistant model was just under the condition of other poor performance.Its use is also very extensive.

And even if the high temperature performance data mentioned in the data here is not as good as the data in the real situation, or it is much lower than the performance in the data, as long as it can work normally at a temperature of 1000 degrees, keep the original data without major changes.

After all, at such a high temperature, Zhang Yi doesn't expect the performance of this bearing steel to remain unchanged, but as long as it is within the bearing range of the bearing steel so that it can work normally, then it is good enough.

After reading the high temperature resistance data, Zhang Yi did not speak, but continued to look down. After all, the high temperature resistance data is only one of the properties of bearing steel, and there are other properties besides the internal high temperature performance.

If only this item of data is excellent, then the bearing made of this bearing steel is at best a very good high-temperature resistant bearing, and the scope of use is quite limited, because the world really needs bearings to withstand such high temperatures. There are not many places to work in China, but very few.

Zhang Yi turned to the next page. The data was the fatigue resistance of this bearing steel. Although Zhang Yi didn't know much about the data, he didn't study metallurgical materials.

But this does not prevent him from understanding the performance of this bearing steel. According to the data on this piece of paper, the highest speed of ordinary bearing steel after the bearing is manufactured, generally speaking, is about a few thousand revolutions per second, even if it is high-speed Bearings, the best high-speed bearings in the world now are less than [-] revolutions per second, and generally high-speed bearings can only last for a few minutes or less at the highest speed.

But this data shows that if this bearing steel is used to make bearings, the maximum speed of the manufactured bearings will be more than five times that of the best high-speed bearings currently used in human society. The bearings that come out can reach a maximum speed of more than [-] revolutions per second.

However, one point has also been explained in the data, that is, to achieve such a speed, the temperature of the bearing must be kept above minus 30 degrees and below 1100 degrees. Only in this range can the best performance of the bearing be achieved. Among them The best temperature is between three and six degrees.

The fatigue resistance of this bearing steel is also very outstanding, it can be said that it completely surpasses all bearing steels on the market today.

After reading this data, Zhang Yi felt even happier. Not to mention anything else, just these two properties of the appeal have already shown that this bearing steel is definitely a very good bearing steel.

Then Zhang Yi turned another page. What caught his eye this time was the wear resistance of this bearing steel. When the bearing works normally, in addition to rolling friction, there is also sliding friction.The existence of sliding friction in the work of the bearing inevitably causes wear and tear on the bearing parts.

If the wear resistance of the bearing steel is poor, the bearing will lose precision prematurely due to wear or the vibration of the bearing will increase and the life of the bearing will be reduced due to the decrease of rotation precision.Therefore, it is required that the bearing steel should have high wear resistance.

The friction resistance of this bearing steel is also very good, which is several times that of general high-performance bearings. Of course, if you want the bearing to have a long service life, in addition to the wear resistance requirements of the bearing steel itself, the machining accuracy also needs to be improved. It plays a very important role, but no matter what, the wear resistance of this bearing steel is also very good.

As Zhang Yi learned about the performance of this bearing steel item by item, Zhang Yi's face gradually revealed an expression of excitement. This bearing steel is not only excellent in high temperature resistance, fatigue resistance, friction coefficient, etc., but also in corrosion resistance. , self-willedness, hardness, and processing performance are also excellent, each of which is basically equal to or surpasses the performance of the best single-performance bearing steel in the world today, which is simply born for the manufacture of bearings.

However, this bearing steel also has its own shortcomings, that is, the smelting of this bearing steel is very troublesome, and the cost is not comparable to that of ordinary bearing steel.
