The production of bearing rings imported steps
1, forging: forging process, if produced in burning, overheating, etc. within the fragmented mesh carbide rings will reduce the toughness and strength. Therefore, we must always be strictly controlled processing temperature cycle of heating and cooling after forging conditions (such as spray cooling) and, in particular, to a large variety of ring final forging, the temperature at 700 ℃ or more, shall not be stacked display.

2, heat treatment: heat treatment equipment for close monitoring is an important task of the workshop. Monitoring equipment reliability. On the instrument, thermocouple temperature control and other important equipment should be closely monitored to ensure accurate and reliable measurement data; of error exceeded the timely replacement of non-sick to run.
3, the grinding process monitoring. Does not allow imports of finished bearing rings of grinding burn and grinding cracks exist, especially with the inner surface of a screwdriver-degree burns are prohibited. Ring if the full inspection should be carried out after pickling, the product bound burns, severe burns or repair can not repair failure should be scrapped, the rings are not allowed to enter the assembly of grinding burn process.
4, identity management, steel storage ring after the first grinding, the process must be strict management and strict distinction between two different materials GCR15 and GCR15SIMN materials and products.
