ABSTRACT:
The feed tip is provided by a pair of spaced apart refractory bodies defining a feed path for the molten metal. Each refractory body has an upstream portion and a downstream edge and the bodies taper, in cross-section, in a direction towards the downstream edge. A discharge gap for the molten metal is defined by the downstream edges of the refractory bodies. The refractory bodies are made from a recently developed material which is a blend of aluminosilicate fibers, silicon powder and a boron constituent, preferably boron nitride.
