Abstract: PURPOSE:To prevent the degradation in the quality of steel ingots owing to the entry of nonmetallic inclusions in molten steel into the steel ingots in the stage of casting molten steel to the steel ingots by a bottom running ingot making method by using runner bricks provided with plural runner holes for a part or the whole of the runner bricks in a molding board. CONSTITUTION:In the stage of casting molten steel into molds 2 through the runner bricks in a molding board 5 from a charging pipe 1 by bottom running and producing steel ingots, runner bricks 3 having plural runner holes 7 are used as the runner bricks. Since the nonmetallic inclusions of large-sized oxidized matter such as molten slag, products of deoxidation, metallic oxides and the like contained in the molten steel are adsorbed and removed on and by the inside walls of the runner holes in the runner bricks, the quantity that such inclusions enter the inside of the molds 2 decreases as compared to that in the prior art, and the steel ingots of high quality contg. less metallic inclusions are obtained. As the number of the holes 7 is larger, the contents of the nonmetallic inclusions in the steel ingots are smaller, and the quality of the steel ingots is higher.
