How to choose a Steel Ball Making Machine? Why choose a Skew Rolling Mill?
In ball mills and bearings, Steel Balls are widely used as a primary component.
Steel balls are currently formed in three ways: upsetting, casting, and skew rolling.
As compared to upsetting and forging, cross-rolled steel balls have a superior productivity, material utilization, and forming quality.
Steel balls made by different processes have different qualities if the same material is used:
Casting <Rolling <Forging
1. When steel balls are cast, they are solidified by molten steel, which will inevitably result in the loosening of internal structures, pores, and other defects, as well as cracks, partial wear, and out-of-roundness.
2. Forged steel balls have the best quality due to their many advantages over forging. While forged steel balls require little investment and can be started quickly, they are labor-intensive and have low output.
3. In rolling, hardness is not as good as forging, but production efficiency and automation are higher.
