Abstract

PURPOSE: To positively pressure weld the continuously cast slab in order to prevent the expansion of the cavity formed in the slab, by arranging the horizontal rolls above and below the position through which the slab is passing, between the caliber rolls being arranged opposite in the vertical mill.
CONSTITUTION: In this rolling mill, the horizontal rolls 3, 3', are set at the position shown with the full line, and the first rolling pass is carried out; hereupon, the slab 2 is fed in the arrowed direction by the guide rollers 13. When the slab 2 comes to the position between the caliber rolls 1, 1, the caliber rolls 1, 1, give the specified reduction in the breadth of the slab 2; and at the same time, the horizontal rolls 3, 3', being arranged above and below the position through which the slab 2 is passing, between the caliber rolls 1, 1, give the reduction in the thickness of the slab 2. That is, the slab 2 undergoes simultaneous reductions at the same position by the caliber rolls 1, 1, and the horizontal rolls 3, 3'; hereby, the expansion of the cavity within the slab 2 along its breadth can be prevented.
