Abstract
PURPOSE:To obtain a cast ingot at a stable shape and superior quality by acting electromagnetic repulsive force upon a molten metal column to conduct the molten metal smoothly into a cooled mold and defining the shape of the ingot by the cooled mold. CONSTITUTION:A dummy bar 17 is beforehand located in a cooled mold 8, and cooling water 16 is flowed into the mold 8 to cool this; At the same time, the cooling water 16 is injected from the lower part of the mold 8. An electromagnetic coil 11 is kept energized. A furnace 1 is tilted to pour molten metal 9 onto the dummy bar 17 through a spout 6 and a heat resistant and heat insulating vessel 7, thereby allowing the dummy bar 17 to descend while the allowing the melt surface to ascend quickly, and starting casting. During this time, the molten metal 9a is curved to the inner side by pinching force by the coil 11, and a head H is held constant. Hence, the molten metal 9a can be smoothly flowed without causing stagnation of flow which is the cause for occurrence of cold shut or the like. Following to this, a solidified shell is formed in the molten metal 9a in the mold 8 by the heat deprived of from the mold walls, and is cooled by the cooling water 16. A cast ingot 15 is drawn by a cylinder 18.
