Production process of Forged steel ball
1)Forged rolling steel balls
Steel rod→Steel rod feeding→Heating→Hot cutting→Hot forging→Rolling→Slow cooling→Quenching→Tempering→Ball cooling→Ball inspecting→Packing and stocking
2)Air hammer forging
Cutting raw material→furnace heating→forging→enter into rolling ball machine→Isothermal system→
quenching system→steel ball sweltering self tempering device→finished product steel ball
