    摘要: A rotary nozzle which is simple in construction and easy to manufacture its bricks, 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 attached to a base member and having at least a sliding surface thereof formed to incline with an angle of .theta..degree., a slide plate surface having at least a sliding surface thereof formed as an inclined surface corresponding to the sliding surface of the fixed plate brick and fixedly mounted, along with a collector nozzle, in a supporting member, and a frame vertically displaceably supporting the supporting member through a plurality of spring means and bolts and adapted to be driven by driving means mounted on the base member. The lower end of the collector nozzle is formed into a spherical shape so as to ensure its smooth connection with a long nozzle and its rotation.
