    grinding ball producing procedure

Brief Introduction of Casting

July 8, 2019/in Castings /by Sara Wu

Casting is the process of melting the metal into a required liquid and pouring it into the mold. After cooling, solidifying and cleaning, a casting (part or blank) with a predetermined shape, size and properties can be obtained It is the basic technology of modern machinery manufacturing industry. The cost of casting blank is low, […]

Quenching is the process of heat treatment to obtain the martensite structure by heating the metal or parts above the phase change temperature and then rapidly cooling them beyond the critical cooling rate. Quenching is to obtain the martensite structure, and after tempering, the workpiece to obtain good performance, in order to give full play […]

The microstructure obtained by high-temperature tempering is tempered sorbite. The main purpose of tempering is to eliminate quenching stress and get the required structure. According to the different tempering temperature, tempering can be divided into a low temperature, medium temperature, and high temperature. Tempered Martensite, troostite, and sorbite were obtained.
