Influence of heat treatment quality on bearing quality
As we all know, the heat treatment of bearings plays a decisive role in their life. FV bearings are also particularly valuable in the heat treatment of rolling mill bearings.
The specific influence of heat treatment quality on bearing quality is as follows:
1. Heat treatment directly affects the life of bearings. High heat treatment temperature will lead to coarse grain, bearing easy to exist quenching crack. Too low quenching temperature, the hardness will be slightly reduced.
2. Too high tempering temperature will lead to the decrease of hardness, and the effect of stress elimination is better. The tempering temperature is too low, the material hardness is high, but the stress is difficult to go out, so the bearing steel generally uses the tempering temperature of 150~180.
3. The influence of heat treatment on bearing life, especially the spheronization treatment, if the spheroidization is not ideal or uneven, the bearing is easy to cause uneven carbide concentration. In the quenching process, the deformation of the ring will increase a lot, but the expansion or reduction is irregular, easy to lead to large deformation resulting in insufficient allowance of scrap.
4. The impact of forgings on bearing life, forgings can be counted as the first heat treatment of bearing manufacturing. If the forging temperature is too high, the grain is coarse, easy to crack during quenching, forging ratio is small, carbide is easy to cause unevenness, will also affect the deformation and cracking during quenching.
