Description

custom grinding steel mill balls Forged steel ball with high quality

Production process of Forged steel ball

1)Fully automatic production line of hot rolling steel ball

Manual put material into storage rack→automatic continued feeding device→stokehole pinch roll feeding device→furnace heating→pinch roll discharging speediness discharging→enter into rolling ball machine→rolling ball quenching system→steel ball sweltering self tempering device→finished product steel ball

2)Semi automatic production line of hot forging steel ball

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

3)Traditional production line of forged steel ball

Cutting raw material→furnace heating→forging→Isothermal system→quenching system→steel ball sweltering self tempering device→finished product steel ball
