What Is Pretreatment Line?
Steel plate pretreatment line shot blasting machine is a multi-functional steel pretreatment line for cleaning welded structural parts, H steel, section steel, grids, and steel plates. The shot blasting device is arranged in multiple angles. The world’s advanced high-efficiency shot blasting device with unit disk blades is selected to project high-speed and dense projectile beams, hitting all parts of the steel in the original state, and perform three-dimensional and all-round cleaning. The rust layer, welding slag, oxide scale and dirt on each surface of the steel quickly fall off, and a smooth surface with a certain roughness is obtained, which improves the adhesion of the paint film to the surface of the steel, and improves the fatigue strength and corrosion resistance of the steel , Improve the internal quality of steel and extend its service life. The main functional components of this machine are the cleaning room, the indoor conveying roller table and the in and out conveying roller table, the shot blasting device, the projectile circulation system (including the hoist, separator, vertical and horizontal screw conveyor, projectile recovery mechanism and pellet supply pipeline). It is composed of mechanism, dust removal, electrical control and other components.
