Rotary nozzle.

摘要

A rotary nozzle which is simple in construction, has no danger of leakage of molten steel and is capable of rotatably connecting a collector nozzle and a long nozzle. The rotary nozzle includes a fixed plate brick (10) attached to a base member (1) and having a sliding surface thereof formed to incline with an angle of theta DEG . A slide plate brick (18) having a sliding surface thereof formed as an inclined surface corresponding to the sliding surface of the fixed plate brick (10) is fixedly mounted, along with a collector nozzle (22), in a supporting member (12). A frame (25) vertically displaceably supports the supporting member (12) through a plurality of spring means (37) and bolts and is adapted to be driven by driving means mounted on the base member. The lower end (24) of the collector nozzle (22) is formed into a spherical shape so as to ensure its smooth connection with a long nozzle and its rotation. <IMAGE>
