Abstract
PURPOSE:To solve the deficiency of the width of an ingot and to improve yield by expanding the spacing between the water-cooled walls of the side faces of a mold continuously in order to prevent the formation of the parts where the width is short by expanding the width of the ingot during continuous casting. CONSTITUTION:When an ingot B of a prescribed width size is expanded in width, first, the drawing of the ingot is stopped until a sufficient outside shell is formed in the molten steel of water-cooled walls 3 of the side faces in the expanded upper steel and therefore the parts right under the step part C are supercooled and shrink to width l smaller than width L in the normal part. In order to eliminate this step part C, the spacing between the walls 3 is expanded gradually from the starting point E thereof in the part D where the deficiency of the width occurs, whereby the part F where the width of the ingot is expanded is formed in the part D and the normal width L is obtained by shrinkage. Thereby, the deficiency of the width of the ingot is solved easily and surely and the ingot of uniform width is cast.
