AN ANODE SYSTEM FOR PLASMA HEATING USABLE IN A TUNDISH

摘要

An anode system for plasma heating usable in the tundish of a continuous casting apparatus, which is economical and simple in structure and can enjoy a long service life, and comprises a dam member (6) provided on the bottom surface of a tundish (1) near and along a side wall or an over-flow wall of the tundish to form a space or gap therebetween, an electrical conductive member (7) with its end portion exposed to the space or gap and the other end electrically connected to a power source, said dam member (6) having a height higher than a level (3c) of molten metal remaining after the pouring of the molten metal from the tundish, but lower than a minimum level (3b) of molten metal normally contained in the tundish (Fig. 1).
