Quenching of alloy cast steel rolls is a heat treatment process in which the roll is heated to a critical temperature (Acm or Ac1), held for a relative time to fully austenitize, and then rapidly cooled to the bainite transformation zone at a cooling rate greater than the critical cooling rate, thereby obtaining the bainite structure in the working layer of the roll body.
The purpose of quenching heat treatment for alloy cast steel rollers is mainly to obtain a good suitable structure for the working layer of the roller, fully utilize the role of alloy elements in the roller, and improve the hardness and wear resistance of the working layer of the roller body.
