Plate pretreatment line

Steel pretreatment line is designed to handle 6-200 – mm steel plate, steel plate after preheating treatment by feeding conveyor system to the closed chamber the shotblast cleaning, the high-speed rotating impeller with a blasting device will steel shot, cast steel shot and cut wire shot) accelerated cast to play to the surface of workpiece, the workpiece to shock, scraping, to remove rust, scale, and dirt on the surface of the workpiece.The high strength nylon roller brush, pill winding screw and high pressure air pipe are used to clean the surface of the workpiece.After derusting the steel plate directly into the spray paint room, through the spray gun installed in the car above and below the spray paint shop maintenance primer spray on the surface of the workpiece, and then into the drying room drying.The paint film on the surface of the steel plate can be sent out as soon as it reaches the dry state.

After the steel plate is processed, the surface reaches a certain roughness, which improves the adhesion between the paint film and the steel plate surface, correspondingly improves the anti-corrosion ability and surface quality of the product, and improves the product grade.
