ABSTRACT A rotary nozzle of the type which is attached to the pouring nozzle of a ladle which contains molten metal for transporting or pouring purposes or in the teeming hole of a converter so as to allow the outflow of molten metal is dis- closed. The rotary nozzle includes a fixed plate brick, a fixed plate supporting frame and a rotor mounted on the outer periphery of the supporting frame by way of a bearing, and a sliding plate supporting frame holding a sliding plate brick secured to the rotor by a hinge so as to be opened and closed. Hooks and springs are attached to the hinge and other hinges to thereby prevent lowering of the sliding plate brick and securely fasten the sliding plate supporting frame to the rotor. This ensures the elimination of preliminary setting which has heretofore been required, easy maintenance, inspection and change of the sliding plate brick, a considerable reduction in the time required for these works and prevention of the molten metal leakage.
