Three criteria for selection of cast steel shot materials

2019-01-31 14:36:33   Review:0 Click:
  Selection criteria for cast steel shot materials:

  Appropriate hardness

  Adequate density

  Appropriate metallographic structure

  Requirements for cast steel shot materials:

  Fast cleaning speed

  Stable quality

  Less consumption

  The relationship between density and life:

  1. Hardness is proportional to cleaning speed, but inversely proportional to service life. Therefore, the hardness is high, the cleaning speed of Cast Steel Shots From Reaguan is fast, but the life is short and the consumption is large, so the hardness of cast steel shot should be moderate (about HRC40-50 is appropriate) to produce the most economical effect.

  2. Moderate hardness and excellent rebound elasticity can be fully cleaned up in every corner of the spraying process to reduce the processing time.

  3. The internal defects of cast steel shot, such as pore cracks and shrinkage holes, can affect its life and increase consumption.

  4. When the density of cast steel shot is greater than 7.4g/cc, the internal defects tend to be the smallest.
