Shot blasting equipment used in the foundry industry first cast steel, cast iron surface adhering sand, and the removal of the oxide skin
Almo st steel castings, gray castings, malleable, ductile iron parts should be carried out blasting treatment. This is not only to clear the casting surface oxide and the sticky sand casting quality check an indispensable preparatory process, such as large-scale gas turbine casing during before the nondestructive testing must be rigorous throwing shot peening cleaning, to ensure that the testing results reliability. In general casting production, throwing the shot blasting machine casting surface defects such as pinhole, slag hole and the sticky sand, cold shut, from the skin, such as the essential means of technology. Non-ferrous metal castings, such as the surface of the aluminum alloy, copper alloy, such as cleaning, in addition to remove oxide scale, found the casting surface defects, but the main purpose is to throw the shot peening to clean the surface quality die casting burrs and get decorating significance to obtain the combined effect. The production of iron and steel metallurgy, throwing the shot blasting machine or pickling is to ensure that the steel mass production to get high productivity and the use of mechanical or chemical joint to phosphorus removal the skin of a technological method. Silicon steel, stainless steel sheet and other alloy steel plate, with the production, must be annealed after shot blasting machine or pickling treatment, to ensure that the surface roughness and thickness accuracy of the cold-rolled steel in the process of cold rolling process
