Description

Technical Field

[0002] The workpiece is heated to a temperature above the AC3 line of steel, fully austenite, and then quickly cooled to a temperature below the Ar3 line for pearlite isothermal transformation. This heat treatment process is usually called isothermal normalizing. It is widely used in the preliminary heat treatment of low-carbon alloy steel and gear steel to refine grains, improve cutting performance, reduce final heat treatment deformation, and improve microstructure.

[0003] After the workpiece is processed, it needs to be heat treated to change its internal structure. This will help improve the performance of the workpiece during its later use. However, after the traditional heat treatment, the workpiece is effectively cooled by water or cooling oil. During the cooling process, a large amount of smoke may be generated between the workpiece and the coolant, which will pollute the surrounding working environment.
