Abstract

PURPOSE:To prevent generation of the fish-tail, by arranging a press machine between the heating furnace and the edging mill, especially nearby the edging mill. CONSTITUTION:A press machine 7 is arranged between the heating furnace 3 and the edging mill 8, especially nearby the edging mill 8. A slab 1 is extracted from the heating furnace 3 and is carried by the table 4 in the arrowed direction (a); when the top of this slab 1 is introduced into the press machine 7, the slab 1 stops and its top is pressed and formed by the pressing tools 14, 14', into a specified tapered shape. Then, the slab 1 is again carried in the arrowed direction (a), and its bottom is pressed and formed by the pressing tools 14, 14', into the specified tapered shape. Next, the slab 5 is pulled away in the arrowed direction (a) from the position of the rolls 18, 18', of the rolling mill 8 within a shortest time. Next, the roll gap of the rolls 18, 18', of the edging mill 8 is set to a specified value, and then, the slab 5 is reversely fed in the arrowed direction (b) and is subjected to an edging work. By thus carrying out the edging work, generation of the fish-tail is prevented.
