The hardness of the steel shot determines the service life of the steel shot. The hardness of the steel shot is directly proportional to the cleaning speed. The higher the hardness, the faster the cleaning speed, and the consumption of the steel shot will shorten the life. The process determines the size of the steel shots. The larger the diameter, the higher the surface roughness after cleaning, but the work efficiency is also high, and the wear compared to the steel shots is also greater. Liaoning Steel Wire Cut Shot
Steel shot is mainly used to clean the workpiece. The choice of steel shot is directly proportional to the work efficiency. The correct choice of steel shot is the key to improving work efficiency. The hardness of the steel shot is high, and the cleaning effect of the workpiece is good, relative to the consumption. Therefore, when using steel shots, you must select the appropriate steel shots according to the material and hardness of the workpiece, so as to increase the service life of the steel shots.
The larger the diameter of the steel shot, the higher the surface roughness after cleaning, but the work efficiency is also very high; the cleaning efficiency of irregularly shaped steel grit or cut steel wire shot is higher than that of spherical shot, but the surface roughness is also higher; High-efficiency projectiles wear out the equipment quickly; it is only calculated by the time of use, but the wear is not fast compared to the production efficiency; the hardness of the steel shot is proportional to the cleaning speed, but it is inversely proportional to the service life .
The higher the hardness of the steel shot, the faster the cleaning speed, but the shorter the service life is, the higher the consumption, so the hardness should be moderate (approximately HRC40-50), the use effect***. Choose steel shots with moderate hardness and excellent resilience, which can reach every place in the cleaning room and can also reduce the processing time.
Steel shots are widely used for descaling and rust removal of steel workpieces before coating. In this case, centrifugal shot blasting equipment is often used. The spherical shape and small hardness prevent the steel shot from causing large wear to the equipment.
