Abstract:
    The present invention relates to a roll-forming method of large-medium-size solid disk-shaped forge piece. Said rolling process includes the following steps: deforming metal rod material, heating, upsetting (pressure machine), cake blank, press moulding (pressure machine), solid disk blank, heating, loading and positioning (rolling machine), axial rolling (rolling machine), measuring and calculating size and obtaining solid disk-shaped forge piece. Its axial rolling force is 2X100000 kg-5X100000 kg, and its widening speed is 5 mm/s-15 mm/s. the rolled disk-shaped forge piece size is as follows; outer diameter is 800 mm-3000 mm and its axial thickness is 30 mm-250 mm.
