The chrome plated steel rod is effectively subjected to rolling processing during the production process, so that the corrosion resistance of the surface of the piston rod can be effectively improved to a certain extent, and the fatigue crack generation can be effectively delayed to a certain extent. expand.
The piston rod is formed by rolling, and the rolling pressure indicates that a cold hardening layer is formed, which can effectively reduce the elastic and plastic deformation of the grinding contact surface to a certain extent, thereby improving the resistance of the cylinder rod surface. Grinding.
After the piston rod is rolled, the roughness of the surface of the internal grinding machine is reduced, so that the matching property can be effectively improved to a certain extent, and the cylinder rod piston can be operated while the sealing ring machine is running or The friction of the seal is damaged, effectively improving the overall service life of the cylinder.
The piston rod is processed by rolling, because the surface layer has surface residual compressive stress, which can contribute to the sealing of the surface micro crack and the expansion of the erosion effect to a certain extent, so that it can be effectively improved to some extent. The ability of the equipment surface to resist corrosion.
When the piston rod is formed by rolling, the rolling surface of the product will directly form a cold hardening layer, which can reduce the elasticity and plastic deformation of the grinding contact surface to a certain extent, thereby improving the wear resistance of the cylinder rod surface. Sex.
When the piston rod is used, it can also effectively prevent the burn caused directly by grinding. To reduce the roughness of the surface after rolling, the product can effectively improve the matching property and reduce the cylinder. The friction of the seal ring is damaged when the rod piston is in operation.
