B3 Forged steel ball mining grinding ball mill grinding media for mine
Forged(hot rolling)steel ball: Our company mainly produces Φ20mm-Φ200mm forged steel ball. Huafu balls feature high accurate dimensions,rounded geometry shape, high hardness and good mechanical properties,wear-resistance,no deformation,no breakage.
Huafu is equipped with advanced casting and forging producing facilities, a full inspection system, well educated professional persons and a management team. We import automatic hot rolling steel ball production line and semi-automatic hot rolling production line for the fast changing market. We also make our advanced heat processing lines. Our products are all produced of good-quality steel. They are cut by plasma cutting machines and heated by electric furnaces which increase the full hardness, impact the toughness and lower the break rate of steel balls.

Production process of Forged steel ball
1)Forged rolling steel ball
Steel rod→Steel rod feeding→Heating→Hot cutting→Hot forging→Rolling→Slow cooling→Quenching→Tempering→Ball cooling→Ball inspecting→Packing and stocking
2)Air hammer forging
Cutting raw material→furnace heating→forging→enter into rolling ball machine→Isothermal system→
quenching system→steel ball sweltering self tempering device→finished product steel ball
