The higher the hardness of the steel shot, the faster the clearing speed, but short life, high cost, all moderate hardness (HRC40-50 or so appropriate) effect.

What is the ratio between hardness and service life of steel shot?

The higher the hardness of the steel shot, the faster the clearing speed, but short life, high cost, all moderate hardness (HRC40-50 or so appropriate) effect. Selection of moderate hardness, excellent resilience performance of steel shot, you can reach the center of the liquidation of the various centers, reduce the disposal time.

The ratio of steel shot hardness to service life is.

1. Hardness is directly proportional to the cleaning speed. The higher the hardness, the faster the cleaning speed, the higher the consumption and the shorter the service life.

2. Only sufficient density can ensure stable quality and reduce rupture and wear during cleaning.

3. Defects such as air holes and shrinkage holes existing inside the projectile material will affect its service life and increase consumption. Hardness is directly proportional to the cleaning speed and inversely proportional to the service life. Therefore, high hardness, cleaning speed, but short life, high consumption, so the hardness should be moderate in order to produce economic results.

The correct selection of steel grit should pay attention to the following issues.

1. Determine the steel shot mainly depends on the type of workpiece you want, commonly used in non-ferrous metals is aluminum shot or steel shot;.

2. Ordinary steel welds, castings, steel and so on.

3. The larger the diameter of the steel shot, the higher the surface roughness after cleaning, but the working efficiency is also very high;.

4. Irregularly shaped steel sand or steel wire cut pellets have a higher cleaning efficiency than spherical pellets, but the surface roughness is also higher; high clearing efficiency, fast wear and tear of equipment; I'm just in the use of time, but it won't be as fast as consuming the efficiency; the hardness of cast steel pills is directly proportional to the speed of removal, and inversely proportional to the service life.
