Abstract
PURPOSE:To prevent the production of internal defects such as porosity, etc. by defining the height-thickness ratio of steel ingot to the specified value or under and making the ingot. CONSTITUTION:Molten steel is poured into a casting mold 1 and slag 4 is dioposed in the upper part of the molten steel 2 in the frame 2 disposed in the upper part of the casting mold 1. Electrodes 5 are positioned in the slag 4 and while the molten steel 3 is being heated by supplying current thereto, the molten steel is allowed to freeze 6 chiefly from the bottom of the casting mold 1. At this casting, the thickness of the casting ingot is made height-thickness ratio 2.2 or under. This methods prevents the production of internal defects of the steel ingot and further prevents segregation, thus enabling the steel ingot of superior quality to be obtained.
