ABSTRACT:
A forging method for making a forged product from an elongate steel bar material. The forging comprises a heating step in which the elongate bar material is heated, a cutting step in which the heated bar material is cut into billet materials each having a predetermined length, and a forging step in which the billet materials are successively forged. In this forging method, when an abnormality arises in the forging step, the cutting in the cutting step is interrupted and the bar material in the heating step is maintained in the heating step without being transferred toward the cutting step. Additionally, unless the abnormality is normalized within a predetermined limit time, the cutting in the cutting step is restarted and the billet materials formed after the restarting of the cutting are transferred to a storing apparatus which is outside of a normal forging line.
