Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or the chemical composition of the workpiece surface. To achieve the purpose of giving or improving the performance of the workpiece.
The heat treatment process generally includes three processes, heating, heat preservation, and cooling. Sometimes there are only two processes, heating and cooling. These processes are interconnected and cannot be interrupted.
The heating temperature is one of the important process parameters of the heat treatment process. The selection and control of the heating temperature are the main issues to ensure the quality of the heat treatment.
Cooling is also an indispensable step in the heat treatment process. The cooling method varies with different processes, mainly controlling the cooling rate.
