Product description
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.
Forged(hot rolling)steel ball are widely used in ball mills in industries such as metallurgical mines, cement and building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemicals, coal water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand, etc.
