  Cast steel grit is widely used for descaling and derusting of steel workpieces before coating, in which centrifugal shot blasting equipment is often used. The shape of the shot and the small hardness make the steel shot not wear the equipment greatly.

  In industry, cast steel grit should be selected well. The standard of choice is: the hardness should be moderate and the size should be uniform. Only in this way can the service life be extended. When used with appropriate equipment, cast steel grit is the best abrasive for surface cleaning because of its durability.

  The hardness property of cast steel grit determines the service life of cast steel grit. The hardness of cast steel grit is directly proportional to the cleaning speed. The higher the hardness is, the faster the cleaning speed will be. The consumption of cast steel grit will be hit and the service life will be short. The manufacturing process of cast steel grit determines the size of cast steel grit. The larger the diameter, the higher the surface roughness after cleaning. However, the work efficiency is also very high, and the wear of cast steel grit is also relatively high Big.

  Cast steel grits are used in different processes, such as surface strengthening, etc. Before coating and bonding, sandblasting can remove all the dirt on the surface of the workpiece, and establish a very important basic schema on the surface of the workpiece. Moreover, by changing the abrasives with different particle sizes, the cast steel grit can achieve different degrees of roughness, which greatly improves the binding force between the workpiece and the coating and plating materials. Cast steel grit is used for steel plate pretreatment, generally used for rust removal before coating.
