What Is Shot Blasting Machine Used For?
- Surface cleaning
Almost all steel castings, gray castings, malleable steel parts, ductile iron parts, etc. must be shot blasted. This is not only to remove the oxide scale and sand on the surface of the casting, but also an indispensable preparatory process before the quality inspection of the casting. For example, the casing of a large gas turbine must be subjected to strict shot blast cleaning before non-destructive inspection to ensure the inspection result. reliability. In the production of general castings, shot blasting is an indispensable process for discovering surface defects of castings such as subcutaneous pores, slag holes, sand sticking, cold insulation, and peeling. The surface cleaning of non-ferrous metal castings, such as aluminum alloys, copper alloys, etc., in addition to removing oxide scales and discovering surface defects of castings, the main purpose is to remove burrs from die castings and obtain decorative surface quality. , To obtain a comprehensive effect. In the production of metallurgical iron and steel, shot blasting or pickling is a process to ensure high productivity in the mass production of iron and steel to remove the phosphorus skin by mechanical or chemical combination. In the production of silicon steel sheets, stainless steel sheets and other alloy steel sheets and strips, the cold rolling process must be annealed and then shot blasted or pickled to ensure the surface roughness and thickness accuracy of the cold-rolled steel sheets.
