成したことを特徴とするスライデイングノズル。 A fixed plate made of a refractory material that is connected to the lower end of the upper nozzle provided at the bottom of the molten steel tank and has one discharge hole communicating with the upper nozzle, and a plurality of through holes in close contact with the fixed plate. A slide plate made of a refractory material is provided, and this slide plate is fixed inside the rotor, and is rotated and slid using a drive device, so that the upper nozzle and one of the through-holes of the slide plate are connected to each other. In a sliding nozzle configured to pour out or block a flow of molten steel through a discharge hole of a fixed plate, a porous brick is fitted into one of the through holes of the sliding plate, and the porous brick is exposed to the atmosphere. A sliding nozzle characterized in that an air blocking plate is provided on the contacting surface, and the gas is blown into the porous brick through a through hole provided in the air blocking plate.
