ABSTRACT:
A rotary nozzle in which at least one coil spring is removed, acting to increase the clearance between a surface of the bottom plate brick and a surface of the slide plate brick. This mechanism is capable of improving the pushing force in the vicinity of the nozzle hole, and prevents molten steel leakage, thus prolonging the life of expensive bricks.
