Continuous casting nozzle with pressure modulator for improved liquid metal flow regulation |
摘要 |
A nozzle for transferring a flow of liquid metal between metallurgical vessels or molds comprising an entry portion for receiving the liquid metal. A flow regulator, such as a stopper rod, is movable from an open position to a closed position with respect to the entry portion for respectively permitting and prohibiting flow through the nozzle. The entry portion and the flow regulator define a control zone therebetween. A pressure modulator, downstream of the control zone, is adapted to minimize a pressure differential across the control zone. The pressure modulator constricts flow downstream of the control zone. |
