The higher the hardness of the
steel shot, the faster the cleaning speed, but the life is short and the cost is high. All the hardness is moderate (about HRC40-50 is appropriate) and the effect is good. Using steel shot with moderate hardness and excellent resilience can reach various centers in the clearing house and reduce processing time.
The ratio of steel shot hardness to service life is:
1. Hardness is directly proportional to cleaning speed. The higher the hardness, the faster the cleaning speed, the greater the consumption, and the shorter the life.
2. Only sufficient density can ensure stable quality and reduce breakage and wear during cleaning.
3. Defects such as pores and shrinkage holes existing inside the projectile material will affect its service life and increase consumption. Hardness is directly proportional to cleaning speed and inversely proportional to service life. Therefore, the hardness is high and the cleaning speed is fast, but the life is short and the consumption is large. Therefore, the hardness must be moderate to produce economical results.
When choosing steel grit correctly, you should pay attention to the following issues:
1. Determining the steel shot mainly depends on the type of workpiece you want. Aluminum shot or steel shot are commonly used in non-ferrous metals;
2. Ordinary steel welds, castings, steel, etc.
3. The larger the diameter of the steel shot, the higher the surface roughness after cleaning, but the work efficiency is also very high;
4. The cleaning efficiency of irregular-shaped steel sand or steel wire cutting pellets is higher than that of spherical pellets, but the surface roughness is also higher; the cleaning efficiency of the balls is high, and the equipment wears out quickly; I just used it for a long time, but it will not be like The consumption efficiency is so fast; the hardness of cast steel shot is directly proportional to the removal speed and inversely proportional to the service life.
