摘要: Build-up on the surface of a refractory body receiving molten metal is eliminated or reduced by making at least a portion of a material that can be electrically heated to at least about 1150.degree. C., such as an alkaline-earth doped lanthanum chromite. When the surface is that of a nozzle or shroud, an electric current is supplied to heat the material around the opening in the nozzle or shroud to at least about 1150.degree. C.
