Hot skew rolling mill for steel ball is a new rolling technology. It is the technical breakthrough of grinding steel ball industries. and gradually replace casting steel ball. The features hot rolling steel ball as following：
1, Hot rolled steel ball has all advantages of steel, and become high-quality grinding steel ball after heat treatment
2, High production rate, large output, rolling steel ball production high mechanization, no manual operation of production, fewer workers, less interference from human factors.
3, Stable quality, high hardness, good hardenability, dense microstructure, fine grain size, no deformation, Steel ball is not deformation, circular shape preservation, excellent wear resistance, Its impact toughness can achieve 12－35J/cm2, the Broken rate is less than 1%；
4, Low energy consumption, non-pollution, low labor intensity, low-cost production
5, Forming good, small geometric tolerance, stable quality.
6, Low wear rate, long lifespan, It is 2-5 times comparing to casting steel ball and forging steel ball and based same.
7, The hardness of steel ball can achieve 60~67HRC, The internal and external hardness is balanced, hardness difference<5HRC
8, Impact toughness achieving 12~35J/cm3
9, high density(7.8~7.85J/cm3)
