SPV235 steel plate surface shot blasting machine process

SPV235 steel plate surface blasting is also a kind of mechanical surface treatment technology with the name, a similar process and SPV235 steel plate surface sandblasting and SPV235 steel plate surface peening.

SPV235 steel plate surface blasting is a cold treatment process, divided into blast cleaning and shot. Just as its name implies is to remove the shotblast cleaning on the surface of oxide skin impurities such as improve the quality of appearance. Blast strengthening is to use high speed movement of the projectile (60-110 - m/s) flow continuous impact by strengthening the workpiece surface, forcing SPV235 steel plate surface and the surface layer (0.10 0.85 mm) in the process of cyclical deformation occurred the following changes:

1. SPV235 steel plate microstructure structure modification;

2. The inhomogeneous plastic deformation of the outer surface is introduced into the residual compressive stress, SPV235 steel plate surface residual tensile stress inside;

3. SPV235 steel plate surface roughness (Ra Rz) change.

Effects: can improve SPV235 steel plate fatigue fracture resistance, prevent fatigue failure, plastic deformation and brittle fracture, improve SPV235 steel plate fatigue life.
