Description of the 30mm high chrome grinding balls

1.Hardness

  Smaller grinding media gets higher hardness. The hardness of the 30mm high chrome 

grinding balls can reach 66 HRC. It becomes preferred choice in the field of mining.

2.Heat treatment

  Heat treatment guarantees quality. In the R & D practice, Dongfang invents Application

Method for Warm Period Timing Quenching in Grinding Materials Heat Treatment and other 

skills. Machine oil is used to quench, making workpiece heated evenly, promoting the first

formed carbide decompose once again and then forming uniformly distributed reticular 

carbides in the matrix. Hardness gap between center and surface is less than 1.5 HRC.

Dongfang is manufacturing highly hard, anti-corrosive and abrasive products whose 

mechanical capacity has reached international advanced level.
