Steel plate pretreatment line
Function of plate rolling machine
Steel plate pretreatment line is applied to remove the rust, oxide scale and contamination on the steel surface, so as to make the surface clean, bright but with a certain coarseness. The paint film can attach to the steel surface more firmly, hence the surface quality and the anti-corrosion capacity of products are improved.
