Steel Plate Pretreatment Line
It is applied to remove the rust, oxide scale and contamination on the steel surface.
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).
Technical details of line:
1.Specification of processable steel plate
