Steel shot is the main consumable of the workpiece during the shot blasting process. The wear of high-quality steel shot is a gradual process. The steel shot is accelerated by the shot blaster and then hits the surface of the workpiece. After each impact, the steel shot deforms. , and will shed a layer of metal. The shape of the steel shot is similar to a sphere, which is a polygon. The impact effect on the casting is equal in each direction. After many impacts, the steel shot continues to become smaller. When it reaches a certain level Then it will be sucked away by the dust collector or separated by the pill and sand separation device.
The surface roughness of the casting after shot blasting is closely related to the strength and projection speed of the steel shots used. The larger the particle size of the steel shots, the higher the roughness of the workpiece surface, the faster the steel shot projection speed, and the surface of the workpiece The higher the roughness, the surface roughness obtained by mixing steel shots with multiple particle sizes is lower than that of steel shots with a single particle size.
