ABSTRACT:
A valve for controlling the discharge of molten metal in a substantially downward direction from a metallurgical vessel has an outer valve part defining an inlet of the valve and an outlet port of the valve, and a refractory inner valve part disposed within the outer valve part in a sealing relationship therewith. The inner valve part has a groove extending therein at the outer peripheral surface which is communicable with the inlet and the outlet port of the outer valve part when the valve is in an open position. The provision of the groove at the outer peripheral surface of the inner valve part does not result in any significant reduction in strength of the inner valve part.
