Steel Plate Pretreatment Line

Function of line:

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, by which the paint film can attach to the steel surface more firmly, hence the surface quality and the anti-corrosion capacity of products are improved.

Components of line:

Steel plate pretreatment line consists of lateral hydraulic pressure feeder and blanker; feeding and blanking roller; shot blast system; dust removing system; inspection roller; automatic paint-spraying system; drying System; as well as electrical control system (including a workpiece detector) .
