Example Embodiment
[0016] Example 1:
[0017] The roller processing technology that is beneficial to reduce heat treatment defects includes a quenching treatment step and a tempering step. The quenching step includes the preheating, heat preservation, and quenching steps of the forming roller with the blank material of 40Cr in sequence. The heating step is to heat the roller to 630-650°C for no less than 5h;
[0018] The heat preservation step is to move the hot roller obtained in the preheating step into a heating furnace with a furnace temperature higher than 870°C and heat it to 840-870°C for no less than 2 hours;
[0019] The quenching is a cyclic cooling method of water cooling and air cooling. After each cyclic cooling method is completed, a tempering is performed. In the quenching process, the temperature of each water-cooling step of the roller is reduced to any value in the range of 60-80°C Value, the temperature of each air-cooling process idler is reduced to any value in the range of 15-30 ...
Example Embodiment
[0022] Example 2:
[0023] This embodiment is further limited on the basis of Embodiment 1: In order to improve the heat treatment efficiency, the slow cooling is furnace cooling.
