A press type method of reducing the slab width wherein a slab as a rolling stock is reduced in width before rolling comprises: employing as press tools a pair of opposed members at least one of which has an inclined press surface adapted to vibrate in the slab width direction; and moving the slab substantially continuously while continuing the vibration of the press tool. Also disclosed is an apparatus suitably employed for the above method. By the method and apparatus, the clearance between the press tools is reduced to make it possible to shorten the operating time as a whole. In addition, the pressed surfaces of the slab are made excellent in continuity thereby to permit improvements also in formability and production yield. |
