Regarding the quality requirement of heat treatment becones higher and higher, the air quenching technology and equipment are developed to meet this demand, The air quenching greatly decreases the disadvantages of traditional quench method.
It effective reduce the deformation, residual stress and crack which caused by liquid quenching, Air quenching effectively lighten the aluminum parts of automobile, provides effective guarantee to high quality and high product tate.
This kind of air quenching equipment can combine with various type of heat treating furnaces, which is suitable for aluminum wheels, cylinder head, cylinder block and also the big irregular aluminum casting part.
