Abstract

PURPOSE:To make possible a compact installation to roll the steel ingot of various sizes, by arranging the vertical roll stand adjacently to the horizontal roll stand, by carving the concave pattern in the rolling roll of either one of these rolling stands, and then, by making possible this rolling stand to move in the axial direction. CONSTITUTION:The vertical roll stand 3' with the vertical rolls 3 is arranged adjacently to the horizontal roll stand 4' with the horizontal rolls 4, and the roll caliber is installed in the upper and lower rolls 5, 6, of either one of these stands. This rolling mill carries out the one or multi-pass continuous rolling of the steel ingot so as to give the area reduction; hereby, the steel ingot with required sectional size and shape is obtained. In this case, plural number of roll calibers 1, 2, 3, are installed in a couple of rolls 7, 8, and one of the stands is moved in the axial detection during the rolling is carried out, so as to use properly the roll calibers; hereby, the stable rolling can be carried out for obtaining more steel ingots of various sizes.
