Abstract
With a rotary nozzle of the type in which a slide plate brick having at least one nozzle bore is rotated so as to adjust the degree of overlapping between the nozzle bore thereof and a nozzle bore of a fixed plate brick to control the rate of pouring of molten steel or the like, the bricks constituting the fixed plate brick and the slide plate brick are formed into the most rational and economical shape for the purpose of seeking a reduction in their cost and also the bricks are used for the purpose of seeking a reduction in the running cost of the rotary nozzle. To achieve these purposes, the shape of the brick 40 is formed into a substantially elliptic shape and nozzle bores 41a and 41b are provided in the respective eccentric positions.
