Bearing is one of the most important parts of bearing ring, imported bearing ring is good, quality also is very good, so how are the imported bearing ring production?
1.
If produced in the process of forging, forging burn, overheating, such as inside crack reticulate carbide decreases the toughness and strength of the ring.
So must always be strictly control the processing temperature, cyclic heating and cooling after forging condition (
Such as spray cooling)
And so on, especially in large breed ring after finish forging, the temperature is above 700 ℃, the shall not be piled up to put.
2.
Heat treatment: heat treatment equipment is closely monitoring workshop is an important work.
The reliability of the monitoring equipment.
For instrument, thermocouple and other important thermostats must be closely monitored, ensure measured data accurate and reliable;
The error exceeds bid to timely replacement, it is strictly prohibited to run in spite of illness.
3.
The grinding process monitoring.
Finished product imports bearing ring grinding burn and grinding cracks are not allowed to exist, especially the inner ring to taper of the mating surfaces shall not be burned.
If ring should be full inspection after pickling, picking burns products, severe burns can't repair or repair the unqualified should be scrapped, grinding burn is not permitted in the ring into the assembly process.
4.
Identity management, steel storage to the front of the ferrule grinding, after each working procedure must be strictly management, strictly distinguish GCr15 and GCr15SiMn two kind of material made of different materials and products.
