ABSTRACT:
In a rotary nozzle brick body formed into a substantially egg-like shape in it's plan view, the present invention secures a contact area of a nozzle portion and improves a configuration factor which considerably affecting the durability of the body. A rotary nozzle brick body is characterized in that the external shape in plan view is comprised of first circular portions (G), second circular portions (H), third circular portions (K), and tangent lines connecting the first circular portions and third circular portions so that a substantially elliptical shape is formed by increasing the circular portion and shortening the tangent lines, instead of a substantially egg-like shape having long tangent lines. Since the substantially elliptical shape is formed by reducing the linear portion of the brick body in it's plan view while the shape is expanded circularly, the contact area is maintained even if the sliding plate brick is rotated up to it's full-opened state, thereby eliminating a fear that molten steel or the like may leak.
