Surface strengthening process and heat treatment requirements of Gcr15 bearing steel solid ball
Gcr15 bearing steel solid ball can effectively improve the steel ball contact labor intensity and surface quality in the process of use, the application of surface modification technology is the surface strengthening treatment of steel ball. The method is that after the steel ball is heat-treated, the steel ball is loaded into a special roller machine. Due to the rotation of the drum, the lifting bucket in the cylinder lifts the steel ball to the top height and falls, and the falling steel ball and the steel ball in the drum Collide with each other.
Gcr15 bearing steel solid ball is only a small circular area in each collision. In operation, as the drum rotation time increases, the number of steel ball collisions increases, and the entire steel ball collision surface becomes larger and larger. It is through this repeated collision method that the surface of the steel ball can be strengthened.
Gcr15 bearing steel solid ball in the surface strengthening process, it is equivalent to a low-speed shot peening process, the steel ball through this processing means, the steel ball in the process of mutual impact, the surface produces elastoplastic deformation, resulting in steel ball The surface structure and stress state of the surface change greatly, and the purpose of improving the surface strength of the steel ball is achieved.
