2.round bar is heated in the modern continuous furnace.
3.the heating bar sent to the rolling mill, and go ahead between two screw rolls. Then steel ball will be rolled on the two rolls. One rolling mill can roll 60-360 pcs/min
4. heat treatment—The process of grinding ball heat treatment to the required hardness takes place in the modern furnace, in junction with large-capacity quenching vessel.
5. finished steel ball with precise dimensions, good geometric shape, good wear resistance and mechanical properties.
