The series steel profiles shot blasting pretreatment line mainly by preheating, shot blasting, painting and drying process components. Applies to ships, automobiles, locomotives, bridges, machinery and other industries surface rust steel, profiles and structural components, painting process. Model: Q698, Q6912, Q6915, Q6920 Product Description: steel shot blasting machine is a steel through automatic shot blasting equipment. After passing shot blasting, surface oxide patent leather and other impurities are cleared away, exposing the workpiece metal color. By simultaneously shot blasting can also eliminate the stress of the workpiece to improve the fatigue strength of the workpiece. Further, since the surface blasting remove impurities, and the coating made the roughness favor and enhance the adhesion of the coating when the coating and prolong the life of the coating to improve the quality of the surface and internal. Steel pretreatment line process refers to the processing of steel in front (ie raw state) shot blasting and surface coated with a protective primer process. After pretreatment of steel and metal products can improve the mechanical components of corrosion resistance, improved fatigue resistance steel, extending its life; while also optimizing the production process of steel surface condition conducive CNC cutting machine cutting and precision blanking. In addition, due to the processing of steel shapes before comparing the rules in favor of mechanical descaling and automated paint, so the use of steel pretreatment can greatly improve the efficiency of the cleanup, reduce labor intensity and pollution clean-up operations on the environment. This machine has high efficiency, low cost, and strengthen, highlighting the advantages of environmental protection, the strength of the metal material surface hardening and rust stain removal ideal equipment.
