<p>A rotary nozzle, in which a sliding plate brick having nozzle holes is turned to adjust an extent, to which the nozzle holes overlap nozzle holes of a stationary plate brick, to control an injection amount of molten metal such as molten steel, and in which a brick body, which constitutes the stationary plate brick and the sliding plate brick is formed in a most reasonable and economical shape to reduce production costs and running costs of a rotary nozzle by the use of such brick body. Thus a brick body (40) is made substantially elliptical in shape and formed at eccentric positions thereof with nozzle holes (41a, 41b).</p> |
