Abstract

PURPOSE: To obtain an ingot having smooth surfaces free from any surface defect by incorporating heating elements in the outlet side wall of a mold.
CONSTITUTION: A mold 1 has heating elements 2. In starting melting and casting, a dummy bar 5 is located at the bottom end of the mold 1, after which metallic granules 4 are supplied with a continuous supply device 3 for the same into the mold 1, where they are heated to melt. Under cooling with the cooling water 7 injected from spray nozzles 6, the bar 5 is lowered by pinch rolls 8. The solidified shell 10 of cast metal is formed by controlling the height of the molten metal 9 in the mold, the inside wall surface temp. at the outlet of the mold, the descending speed of the bar 5, and the supply rate of the granules 4. As the bar 5 descends, the shell 10 grows to form an ingot 11. At this time, it is important to control these in such a way that the molten metal 9 does not form the shell 10 along the side walls in the mold and forms the shell quickly in the outside of the mold outlet. To this end, the inside wall surface temp. at the mold outlet is maintained at above the solidifying temp. of the cast metal by the heating elements 2.
