Bearing steel production why control rolling and cooling

Bearing steel production to control rolling and cooling reasons are.

1, rolling through the control of rolling and cooling, can significantly improve the bearing steel mesh carbide mesh organization.

2, in order to get the best carbide reticulation level, the final rolling temperature control in the range of 780 ~ 830 ℃, on the cold bed back to red temperature ≤ 690 ℃. Can get the relatively best reticulation level.

3, control rolling and cooling, can be rolled material can be shortened ball annealing time, reduce energy consumption and improve production efficiency.
