Background technique

Shot blasting machine is a shot blasting equipment that uses high-speed projectiles thrown by a shot blaster to clean or strengthen the surface of castings. The shot blasting machine can shake out sand, remove core and clean the casting at the same time.

Shot blasting equipment is firstly used to remove sand and scale on the surface of cast steel and iron castings in the foundry industry. Almost all steel castings, gray castings, malleable steel parts, ductile iron parts, etc. must be shot blasted. This is not only to remove scale and sticky sand on the surface of the casting, but also an indispensable preparation process before the quality inspection of the casting. For example, the casing of a large gas turbine must be subjected to strict shot blasting before non-destructive testing to ensure the accuracy of the testing results. reliability. In the production of general castings, shot peening cleaning is an indispensable process to find surface defects of castings such as subcutaneous pores, slag pores, sand sticking, cold shut, peeling, etc. The surface cleaning of non-ferrous metal castings, such as aluminum alloys, copper alloys, etc., in addition to removing scale and finding surface defects of castings, the main purpose is to remove burrs of die castings and obtain decorative surface quality by shot blasting , to obtain a combined effect.

According to the modern metal strength theory, increasing the dislocation density inside the metal is the main direction to improve the metal strength. Practice has proved that shot blasting is an effective process for increasing metal dislocation structures. This is even more important for some metals that cannot be hardened by phase transformation (such as martensitic quenching, etc.) or require further strengthening on the basis of phase transformation hardening. Aviation, aerospace industry, automobiles, tractors and other parts require light weight, but the reliability requirements are getting higher and higher.
