Abstract

PURPOSE:To almost straighten the both ends of steel plate after rolling by the procedure in which the biting at the time of rolling is started with the one corner of slab and then another biting is started with one corner other than the corner and its diagonal line. CONSTITUTION:The slab 3 is started to roll from the side I of the roll 1, and then reversed by biting it from the side II. This cycle is repeated for rolling. In this case, in the case of rolling from the side I, biting is started with an inclined angle to the rolling axle 0-0 from the one corner A of the slab 3 or from the corner A' on its diagonal line. And, in the case of rolling from the side II, biting is started with a slant attitude in such a way that rolling is started from any of the coners B and B' except the corners A and A'. This method enables one to nearly straighten the both ends of steel plate after rolling even in case where broadside ratio is greater, and therefore to make the cutting loss after rolling smaller. Thus, the rolling yield can be raised.
