CONTINUOUS CASTING APPARATUS FOR INGOTS OBTAINED FROM TITANIUM OR TITANIUM ALLOY

摘要

The continuous casting apparatus is provided with: a bottomless mold with a circular cross-sectional shape into which molten metal of melted titanium or titanium alloy is poured from the upper opening and is extracted downward as the molten metal is solidified; and plasma torches, which are disposed above the molten metal in the mold and are for generating plasma arcs for heating the molten metal. Ingots are continuously cast by moving the multiple plasma torches, which are disposed above the molten metal in the mold, in the horizontal direction above the surface of the molten metal along paths that maintain a distance such that the torches do not interfere with each other.
