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 .
