Abstract

PURPOSE:To preform the finish-rolling into the desired width, by utilizing the property that the widening of the steel sheet is different depending on the draft-percentagedistribution in each stand of the finisher, when the rolling is applied on the slab on purpose to obtain the steel sheet of a specified width using a rougher and plural stands of finisher.
