Why Can We Always Ensure Excellent Quality

Quality Control

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 .
