The working principle of heat treatment equipment mainly involves the heat treatment process of metals, which is to heat metal workpieces in a certain medium to a suitable temperature, and after maintaining it at this temperature for a certain period of time, cool it at different speeds. By changing the microstructure of the metal material surface or interior to control its properties, such as improving the internal organization of the metal, controlling uneven organization and residual stress, changing the machinability of steel, improving surface hardness and wear resistance, etc.
Heat treatment equipment is mechanical equipment used to heat a workpiece or a surface of a workpiece and cool it at an appropriate rate to obtain the required microstructure and performance. The following are details and classifications of heat treatment equipment:
I. Working Principle
The working principle of heat treatment equipment mainly involves the heat treatment process of metals, which is to heat the metal workpiece in a certain medium to a suitable temperature, maintain it at this temperature for a certain period of time, and then cool it at different speeds. By changing the microstructure of the surface or interior of the metal material, its properties are controlled, such as improving the internal microstructure of the metal, controlling uneven microstructure and residual stress, changing the machinability of steel, improving surface hardness and wear resistance, etc.
II. Equipment Classification
