The steel plate pass-through steel plate pretreatment line has high dust removal effect and high shot blasting efficiency to ensure the essence of the steel plate. At the same time, the wear-resistant parts have also been improved to increase the life of the wear-resistant parts.
The steel plate pretreatment line specializes in processing 6-200mm steel plates. After preheating, the steel plates are sent to the closed shot blasting room by the feeding conveyor system, and the steel shots (cast steel shots and cut steel wire shots) are accelerated by the high-speed rotating impeller of the shot blasting machine Polish to the surface of the workpiece, impact and scrape the workpiece to remove rust, oxide scale and dirt on the surface of the workpiece. Use the high-strength nylon roller brush of the scraping device, the collecting screw, and the high-pressure air pipe to clean the accumulated pellets, dust and floating dust on the surface of the workpiece. The rust-removed steel plate directly enters the painting room, and the workshop maintenance primer is sprayed on the surface of the workpiece through the spray guns installed on the upper and lower painting carts, and then enters the drying room for drying. The paint film on the surface of the steel plate is quickly sent out after reaching the finger dry state.
After the steel plate is treated, the surface reaches a certain degree of roughness, which improves the adhesion of the paint film and the surface of the steel plate, correspondingly improves the corrosion resistance and surface quality of the product, and improves the product grade. In addition, because the steel shape is relatively regular before processing, it is conducive to mechanical rust removal and automatic paint spraying. Therefore, the use of steel pretreatment can greatly improve the efficiency of cleaning work and reduce the labor intensity of cleaning work and environmental pollution.
