All mechanical quality of the soul - heat treatment knowledge A little knowledge of the mechanical person should know that heat treatment is to give the inherent quality of the soul of the machine, China's mechanical processing is not bad, but the heat treatment level yet to be improved, burning it, the robot when the self- Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but by changing the microstructure inside the workpiece or changing the chemical composition of the workpiece surface , To give or improve the use of the workpiece performance. Which is characterized by improving the intrinsic quality of the workpiece, which is generally not visible to the naked eye. Heat treatment process generally includes heating, heat preservation, cooling three processes, sometimes only heating and cooling ...
