Abstract
A sliding gate valve of the type in which refractory gates are sequentially disposed in operative position beneath the pour opening from a teeming vessel, such as a tundish, is effective to controllably throttle the metal flow stream from the vessel. Operator means for positioning the gates in order to control the degree of throttling of the flow stream are independent from the operator means for disposing the gates in their working position within the valve mechanism whereby the flow stream can be terminated without adjusting the throttling configuration of the valve. Means are provided, when the valve employs a pour tube attachment, for selectively changing gates and pour tubes in unison, or independently from one another. The valve mechanism and its replaceable refractory components are designed for the supply of fluids for cooling these members and for the injection of fluid reactants into the metal pouring process.
