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
20mm-40mm hot rolling steel ball production line
