Technical process of heat treatment of wear-resistant plate
The purpose of heat treatment is to change the internal structure of the wear-resistant plate, and then improve the technical performance and service performance of the workpiece, tap the potential of the wear-resistant plate, extend the service life of the parts, and further improve product quality.
Heat treatment is a processing technology in which the wear-resistant plate is heated to a predetermined temperature in a solid state, adhered to for a certain time, and then cooled down by a certain cooling method. The technical process is: heating ----- insulation ------ cooling.
The heat treatment technology of wear-resistant plate refers to the detailed heating and thermal insulation cooling technical parameters of wear-resistant plate drawn up according to the structure transformation law of wear-resistant plate in the heating and cooling process. There are many kinds of heat treatment technology, according to heating, cooling methods and different arrangements and performance, the heat treatment technology of wear-resistant plates can be divided into: ordinary heat treatment (annealing, normalizing, quenching and tempering), external heat treatment (deformation heat treatment, magnetic field heat treatment, etc.), according to heat treatment can be divided into preparatory heat treatment and final heat treatment.
In theory, the general carbon content of 0.8% wear-resistant plate, the quenching temperature range is about 750 ° C, which requires special attention, otherwise the microstructure of steel can not be achieved, heat treatment quenching will lose the predetermined effect.
Wear-resistant plate for hot working is one of the indispensable process methods in the production of industrial products. It is mainly used in manufacturing and processing industries. It is used as a forming tool with stamping, forging, casting forming machinery, and forming machinery with plastic, rubber, ceramics and other non-metallic material products.
