REPLACING DEVICE FOR IMMERSION NOZZLES |
摘要 |
A submerged nozzle changing apparatus comprises: a slide valve device (32) for controlling the rate of discharge of a molten metal from a molten metal container (30); a nozzle holding cylinder actuator (42) supported in a vertical position under the slide valve device; and a guide arm unit (44) supported on the piston rod (43) of the nozzle holding cylinder actuator in a horizontal position. The guide arm unit (44) has a pair of parallel guide rails (45) provided in their inner surfaces facing each other with guide grooves (46) having open opposite ends and a length long enough to hold at least three nozzle cases (48) fitted on the upper parts of submerged nozzles (47). A new submerged nozzle is supported on the guide arm unit with portions of a nozzle case fitted on the upper part thereof engaged in the guide grooves of the pair of guide rails and is moved to a nozzle setting position by a nozzle changing cylinder actuator (56).
