Heat treatment method for crusher parts

E-mail: jacker@cfcmining.com

Heat treatment is the process of heating or cooling a metal material by changing the structure of the metal to obtain the desired properties. These processes are often used in crusher parts.
1. Quenching: Simply speaking, it is a treatment method in which the material is heated and then cooled to make it hard. It was found in the manufacturing process of the former Japanese knife. Of course, not everything is heated and cooled. A variety of different materials (components) have corresponding heating temperatures, holding times and cooling methods.
2. Annealing: This is a heat treatment method in which the heated material is slowly cooled to soften it or to eliminate its residual stress. This of course also has heating temperature, holding time and cooling method.
3, tempering: only quenching treatment, it will become hard and brittle, due to residual stress and deformation and other issues. In order to solve this problem, the tempering treatment is performed, that is, the state of the material after quenching is precipitated or precipitated, and a stable structure can be obtained. In order to obtain such a structure, the operation of heating it to a certain temperature and then cooling is called tempering.

4. Normalizing: The operation mode of cooling the workpiece to austenitizing and cooling in the air is called normalizing. Through normalizing, the structure of the workpiece will become finer ferrite structure or microstructure of cementite and pearlite, thereby improving its mechanical properties, eliminating the factors affecting its processing and improving its toughness. In addition to this, there are martensite method, austenite method, solution heat treatment, and precipitation hardening treatment in the heat treatment of steel.
