Process Features of Forged Steel Balls | |
1.Material stability
| Round steel-the raw material of forged balls, are totally ordered from our national large-scale steel mills. We can also provide special processing as per special requirements. |
2.Heating of raw material
| We use energy- efficient induction bar heating furnace. Advantages: A.Ensure uniform temperature of the entire raw material, and then the uniform temperature can ensure even hardness during heat treatment process. B.Lower raw material consumption. |
3.Forging Forming | The raw material is forged to a certain deformation by air hammer, increase the compression ratio,So that to dense the structure of wear-resistant ball and improve the toughness and hardness.
|
4.Heat treatment | We use independently-developed water quenching heat treatment production line and scientific heat treatment process. Our forging grinding balls have the specialities of higher hardness (from surface to the core), And high toughness and low breakage. They can even maintain the stability under various poor working conditions. |
