3, After red state of steel bar is fed into the ball rolling mill, it will rotate between the two rollers with special spiral groove, and then continuously rolling as steel ball. Each ball rolling mill can roll 60 ~ 120 steel ball per minute.

4, Red state steel ball after rolling will immediately put into on-line heat treating machine for quenching - tempering treatment, make steel has high and even hardness.
5, Finished steel ball have precise dimensions, good geometry shape, good wear resistance and mechanical performance.
