Cooling is an indispensable step in heat treatment process, in Gravity Die Casting industry, cooling method will be different because of different casting process and heat treatment process. Mainly to control the cooling rate and speed. In general annealing is the slowest, quenching speed is faster.
Heating temperature is one of the important process parameters of heat treatment process. The selection and control of heating temperature is an important problem to ensure the quality. When using high energy density heating and surface heat treatment, the heating speed is fast. Generally, there is no holding time, and the holding time of chemical heat treatment is usually longer.
