Cast Steel Shot is one of the most common metallic abrasive. It is widely used for descaling and rust removal of steel workpiece before coating. In this case, it is usually used in centrifugal shot blasting equipment. Its round shape and small hardness could reduce the wear and tear on equipment. Meanwhile, cast steel shot is also widely used in foundry industry. When workpiece is take out of the mold, it is used to remove the burr and sand on the surface of workpiece. It is definitely the best abrasive for surface cleaning because of its durability when used in suitable equipment. Cast Steel Shot is made by melting, atomizing and cooling processes. Firstly, steel material is put into heating furnace and high temperature melt the material into liquid. Secondly, these melt liquid is poured into an atomization device. High pressure and high speed atomizing medium coming out from the atomizing nozzle of atomization device, which is the key part of cast s…
