Customers who use shot blasting machines want to find the right steel shot. Choosing good quality steel shot can not only improve the service life of the shot blasting machine and its wearing parts, but also improve the surface quality of the product. The type and size of the pill mainly depends on the workpiece you want to clean:
Non-ferrous metals generally use aluminum shot or stainless steel shot; ordinary steel and its welding parts, castings, steel, etc. use steel shot;
The larger the diameter of the steel shot, the higher the surface roughness after cleaning, but the cleaning efficiency is also high;
The cleaning efficiency of irregular-shaped steel grit or steel wire cutting shot is higher than that of spherical shot, but the surface roughness is also high;
The projectile with high cleaning efficiency also wears the equipment quickly (relatively), it is only calculated by the time of use, but compared with the production efficiency, the wear and tear is not fast.
a) The hardness is proportional to the cleaning speed, but inversely proportional to the life. Therefore, the hardness is high, the cleaning speed is fast, but the service life is short and the consumption is large, so it should be used in moderation (approximately HRC40-50).
b), moderate hardness, with excellent resilience, so that the steel shot can reach every place in the cleaning room, reducing the processing time. c) The internal defects of the projectile, such as porosity cracks, internal shrinkage holes, etc., can affect its life and increase the consumption.
d) If the density is greater than 7.4g/cc, the internal defects should be minimized.
Steel shot centrifugal pill forming technology is the preferred choice for producing national standard steel shots
