Abstract

An improved sliding plate valve having a plurality of relatively slidable refractory orifice plates in face-to-face contact to control the flow of molten metal through the valve, characterized in that at least one of the plates has at least one one of its opposed surfaces a pulverized or thermally atomized reservoir of a refractory material having a resistance to wear, erosion and corrosión by the molten metal equal to or greater than that of the material from which the body of the plate is made.
