QC Profile

All the raw material-steel rods are produced by reputable large scale steel mills. We can also arrange special 

processing for different requirements of the steel raw material . We use an electric furnace to heat the raw

 material, in order to make sure all the materials can reach the correct temperature and reduce unnecessary

 loss during heating .

To obtain high hardness,strength,toughness and superior wear resistance ,the forged steel balls undergo heat 

treatment, water quenching, and tempering.

During the heat treatment, we use advanced Isothermal temperature control technology, to insure the uniformity

 of the hardness of the grinding balls .
