Abstract

The stopper includes a sliding plate, which has a middle zone employed to close the outlet hole in the base of the nozzle. An outlet hole is provided near each of the two ends of the sliding plate. The plate is moved along a straight path by a double-acting hydraulic cylinder so the total path length of the plates in the hydraulic cylinder corresponds with the distance between the two outlet holes in the sliding plate. The hydraulic cylinder has a pipe at each end for the supply or evacuation of hydraulic fluid, and a middle pipe for the removal of the hydraulic fluid. Each of the three pipes is fitted with a valve connected in a hydraulic circuit employed to drive the sliding plate. The sliding plate can easily be moved to start or stop the flow of molten metal from the ladle.
