Abstract

An inductively heated drain tube fashioned of high temperature, electrically conducting materials is disclosed. An inductor surrounds the drain tube. The inductor and drain tube are cast within a refractory material. The drain tube is then placed in communication with the side of a bath of molten materials. When power is supplied to the inductor, the inductor couples with the drain tube, heating the drain tube and allowing it to act as a drain for high temperature molten materials. When power is removed from the inductor, a flow of cooling liquid through the inductor cools the drain tube, solidifying the molten materials and stopping their flow through the drain tube. The refractory material encases the inductor, acting as a thermal barrier and preventing damage from molten materials.
