Grinding steel balls are a main tool for grinding materials, usually used in ball mills. Grinding steel balls produce abrasive effects through collision and friction with the materials, thereby achieving the grinding effect of the materials
Forged Ball Details:
Forged steel balls are obtained by heating the metal to a suitable temperature, applying pressure to the metal blank by forging, causing it to undergo plastic deformation to obtain steel balls with certain mechanical properties, shapes and sizes.

Casting Ball
Casting steel balls are made by heating and melting scrap steel, scrap iron and other waste furnace materials in a medium frequency electric furnace, and adding appropriate amounts of precious metal alloys (such as ferrochrome, ferromanganese, ferrovanadium, etc.) during the melting process to temper the chemical composition. When the molten iron temperature reaches above 1550℃ and meets the process requirements, the qualified molten iron is poured into the steel ball mold, and the spherical iron alloy wear-resistant body is made through quenching, tempering, testing and packaging.
1) Traditional Forged
Raw material →Cutting →Heating → Water quenching → Tempering
2) Auto Hot Rolling
Raw material →Hot Rolling Mill → Water Quenching → Tempering
3) Casting
Raw material preparation →Smelting→ Pouring→Cooling and demoulding→Heat treatment and inspection
