    Abstract: An improved multilayer coating for use on molten metal holding and transfer apparatus, the coating including a bond layer applied directly to the surface of molten metal holding and transfer apparatus, and a porous layer of ceramic material produced by co-deposition of a powder of said ceramic material and a powder of a suitable organic polymer material and, after the co-deposition, heating of said polymer material to thermally decompose the polymer material and form the porous layer. The bond layer preferably is formed of a metallic, intermetallic or composite particulate materials. The metal component may be in the metallic, intermetallic, oxide, clad or alloyed form consisting of any one or more of the metal components selected from the group of Mo, Ni, Al, Cr, Co, Y and W and may be in combination with yttria, alumina, zirconia, boron, carbon and have a particle size in the range of 5 to 250 m, typically 40 to 125 m. The bond layer preferably has a thickness of 5 to 300 m with a substantially uniform coating layer being provided over the surfaces to have the porous ceramic coat applied.

    Abstract: A method for continuous casting of steel, characterized in that use is made of a combination of a mold powder having a fluorine content of less than 3 wt % and exhibiting a viscosity at 1300 °C of 4 to 10,000 poise and an immersion nozzle comprising a refractory material containing alumina as a primary component (specifically, an alumina refractory and/or alumina−carbon refractory). The method allows the stable production of a clean cast steel product with little melting loss and with no deposit of alumina, also in the case when an immersion nozzle comprising a refractory material containing alumina as a primary component is used.

    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.
