Abstract: The discharge rate of a solid particulate material from a storage hopper is increased beyond the rate attainable by gravity flow along through the introduction of a pressurized gas into a plenum that lies over the discharge hopper. In one embodiment, a first pipe extends vertically downward from a storage hopper, and a second pipe of larger diameter is fitted over the lower end of the first pipe so that an annular plenum is formed between the pipes. A pressurized gas is injected into this plenum and results in an increase in the discharge rate. The discharge rate can be controlled by altering the pressure of the injected gas, and the flow can be rendered intermittent by opening and closing a gate valve at the outlet of the discharge hopper.

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.
