This series is a kind of multifunctional steel pretreatment equipment for steel plate and profile steel. The blast wheel is multi-oriented and high-efficient adopting world-advanced unit serpentine curve blades; It could throw high-speed and dense shots, which hit on each position of steel plate in original state, to clean solid and all-directionally, make rust layers, welding slag, roll scale and feculence on surface of steel plate shed quickly and obtain smooth surface with certain roughness, which well improve adhesive strength between the paint film and steel surface, promote fatigue strength and corrosion resistance of steel, improve the inherent quality of steel and prolong its use life.
