The change in the cooling characteristics of large sheet metal processing can be adjusted by changing the viscosity of chemical substances, temperature, level gauge pressure, application of additives, agitation, etc. The higher the viscosity of the heat treatment oil and the higher the temperature, the smaller the elliptical deformation. The deformation is smaller under the premise of not moving in place. Is to have more in line with the characteristics of improving the operating process of professional skills professional processing methods, and how to scientifically and reasonably reduce the plate metal processing deformation? Can effectively reduce the deformation of Suzhou plate metal processing: salt milk bath heat treatment; high temperature oil heat treatment; release pressure heat treatment; a tank of three heat treatment. Salt milk bath heat treatment and high temperature oil heat treatment is similar, are heat treatment at the austenite transformation temperature, so that the uniformity of austenite change. In the current economic environment, the development of many industries is difficult. The development of the aluminum sheet metal processing industry is certainly all subject to many obstacles. In order to enhance the current economic environment of the constraint, it is necessary to engage in each step of its own development.
