    Abstract: A gas injected upper tundish nozzle comprising: a protective can; a ceramic inner portion disposed within said protective can, said ceramic inner portion having gas flow pathways therein; a gas injection port attached to said protective can allowing for the injection of gas through the protective can and into the gas flow pathways within the ceramic inner portion. A gas flow seal is formed between the protective can and the ceramic inner portion. The gas flow seal blocks gas leakage from the gap between the protective can and the ceramic inner portion. The gas flow seal is formed of nickel or an alloy of nickel.

    Abstract: An inductively heated drain tube fashioned of high temperature, electrically conducting materials is disclosed. An inductor (11) surrounds the drain tube (12). The inductor and drain tube are cast within a refractory material (14). 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 (13). 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.
