Abstract: A slide gate assembly for use with a metal-working vessel comprising at least one stationary refractory plate and at least one sliding refractory plate slidably engaged with said stationary plate, said refractory plates each having at least one passage therethrough and spaced in relation to each other such that said sliding refractory plate can be moved to bring its passage into and out of alignment with the passage of said at least one stationary plate to effect discharge or retention of molten metal in said metal-working vessel; at least a portion of each of said refractory plates consisting essentially of an unburned high-strength carbon-bonded magnesite refractory containing at least about 5% by weight carbon and at least about 74% by weight magnesite.

Abstract: Refractory brick comprising a refractory aggregate, carbonaceous material and powdered metal bonded with a combination of liquid thermosetting resin and impregnating pitch.

Abstract: Carbon bonded refractory brick containing 1 to 6% by weight liquid thermosetting resin binder consisting of polyhydroxydiphenyl resin and a curing agent and the balance being refractory aggregate.
