Shot blasting machine is a kind of casting equipment which can clean or strengthen the surface of castings with high-speed shot thrown by shot blasting machine. The shot blasting machine can remove sand, core and clean the casting at the same time. Some areas are also called sanding machine and sandblasting machine.
Shot blasting machine is a kind of processing technology that the steel sand and steel shot are dropped and impacted on the surface of material object by shot blasting machine at high speed. Compared with other surface treatment technologies, it is faster and more effective, and can be used for casting process after partial retention or stamping.
Shot blasting machines can also be used to remove burrs, diaphragms and rust that may affect the integrity, appearance, or definition of parts of an object. The shot blasting machine can also remove the surface pollutants for a part of the coating surface, and provide a surface profile to increase the adhesion of the coating, so as to achieve the purpose of strengthening the workpiece.
Shot blasting machine is different from shot blasting machine in that it is used to reduce the fatigue life of parts, increase different surface stress, increase the strength of parts, or prevent fretting.
Shot blasting equipment is firstly used to remove sand and oxide scale on the surface of cast steel and iron castings in foundry industry.
Almost all steel castings, gray castings, Maanshan Steel Castings, ductile iron castings, etc. should be shot blasted. This is not only to remove the oxide scale and sand on the surface of the casting, but also an indispensable preparation process before the casting quality inspection. For example, the large gas turbine casing must be strictly shot peened before the NDT, so as to ensure the reliability of the flaw detection results. In general casting production, shot peening is an essential process to find surface defects of castings, such as subcutaneous air holes, slag holes, sand sticking, cold shut and peeling. The surface cleaning of non-ferrous metal castings, such as aluminum alloy and copper alloy, is not only to remove the oxide scale and find the surface defects of castings, but also to remove the burr of die castings by shot peening and obtain the surface quality with decoration significance, so as to obtain the comprehensive effect. In metallurgical iron and steel production, shot peening or pickling is a kind of mechanical or chemical combined process to remove phosphorus scale to ensure high productivity in mass production of iron and steel. In the production of silicon steel sheet, stainless steel sheet and other alloy steel sheet and strip, annealing must be carried out before shot blasting or acid pickling to ensure the surface roughness and thickness accuracy of cold rolled steel sheet.
