At present,the main method of steel surface-treatment is acid pickling and dry shot-blasting. Acid pickling is environmental pollution and pickled products have over pickling,insufficient cleaning defects.Dry shot-blasting is dusty,descaling poor and low efficiency.This paper proposes a new slurry-blast descaling technology without defects mentioned the above.Surface roughness of treated steel has a greater impact on the coating quality. Authors studied the roughness change regularity of the steel surface by changing processing parameter,such as grit size,steel strength,processing time,and projectile velocity,then studied the roughness change trend of the slurry-blasted plate treated by skin pass process.The results can be used to guide the slurry-blasting process.
