Forgedball Workflow

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
