Steel Plate Shot Blasting Machine is a special piece of equipment for multi-functional surface pretreatment of welded structures, H-beams, section steels, steel grids, and steel plates. It is widely used in steel structures, plate processing, shipbuilding, engineering machinery, automotive, wind power, bridge, and other industries, mainly for pre-coating surface treatment. Some models can also perform plate surface strengthening.
Applications
Steel Structure Industry: Rust and oxide scale removal for workshop steel structures, steel box girders, steel columns, roof trusses, and other structural plates to improve coating adhesion for subsequent painting.
Plate Processing Industry: Surface cleaning for hot-rolled steel plates, cold-rolled steel plates, stainless steel plates, and aluminum plates, removing oxide scale and oil stains from rolling to improve surface finish.
Shipbuilding Industry: Rust removal pretreatment for ship decks, hull plates, and cabin plates to meet high anti-corrosion requirements in marine environments.
Engineering Machinery Industry: Surface cleaning for frames and hood plates of excavators, loaders, cranes, and other equipment for subsequent coating.
Wind Power & Bridge Industry: Cleaning of thick steel plates for wind tower segments and bridge steel box girders, with surface quality meeting high-grade coating standards.
Automotive Industry: Surface cleaning for thin steel plates of automotive body parts and frame plates, removing oil stains and burrs from stamping.
Core Treatment Effects
Cleaning Effect: Thoroughly removes oxide scale, rust, oil, welding slag, and burrs. The surface shows a uniform metallic color without residues or blind spots.
Pretreatment Effect: Creates a uniform rough surface with roughness Ra 1.6–6.3 μm (adjustable via conveyor speed and abrasive size). Coating adhesion is improved by more than 30%, and service life is extended by 2–3 times.
Operation Effect: Continuous operation with no manual error, ensuring high consistency for the same batch. Processing speed is adjustable for different contamination levels.
Environmental Effect: Fully sealed structure with high-efficiency dust removal. Dust emission concentration ≤ 30 mg/m³, compliant with national standard GB 16297-1996. No abrasive splashing, ensuring a friendly workshop environment.
Non-standard customization is available.
