Abstract

PURPOSE:To uniformize the distribution of AlN precipitation in the direction of the slab's breadth, by performing the width-gauge control rolling at respectively specified rolling reduction to both edges of the hot case slab solidified after the continuous casting of the aluminum killed molten steel. CONSTITUTION:The aluminum killed molten steel is continuously cast to produce the hot cast billet solidified completely; the low temperature parts on both edges of this cast billet are respectively edged at a rate of breadth reduction >=50mm./one pass in order to raise the edge temperatures and to promote the precipitation of AlN at the edges. Hereby, the distribution of AlN precipitation at the section of the slab in the breadth direction is uniformized, and the material's internal quality can be improved.
