The most important part of the bearing is the ferrule of the bearing; the ferrule of the imported bearing is very good; the quality is also very good; then how does the ferrule of the imported bearing come out?
1. Casting: If the over-burning, overheating, and internal cracking into mesh carbides occur during the casting process, the resistance and strength of the ferrule will be lowered. Therefore, it is necessary to strictly control the processing temperature, circulating heating and heat dissipation conditions after forging (such as spray Cooling), etc.; especially after the larger type of ferrule is finally forged; the temperature is above 700 Â°C;
2. Heat treatment: close monitoring of heat treatment equipment is an important work in the workshop.
The reliability of the monitoring equipment. The important temperature control tools such as external watches and thermocouples must be closely monitored; the measurement data should be accurate and reliable, and the errors should be replaced in time; the disease operation is prohibited.
3. Monitoring of the grinding process. The imported bearing ring is not allowed to have grinding burns and grinding cracks; in particular, there should be no burns on the cooperation surface of the inner ring taper. If the ferrule is pickled, it should be fully inspected; Remove burn products; severe burns that cannot be repaired or repaired unqualified should be voided; ferrules that have burned burns are not allowed to enter the installation process.
4, the identification of the handling; steel into the warehouse before the lap ring grinding; each process must be strictly handled; severely distinguish between GCR15 and GCR15SIMN two different raw materials and products.
