ABSTRACT:
A rotary nozzle system attached to the outlet of a metallurgical vessel to serve as a gate valve for controlling the rate of pouring of molten metal. A slide plate brick and bottom plate brick, each having a nozzle bore, are relatively rotated in a surface-to-surface contact condition to adjust the degree of communication opening of the nozzle bores. Each of the plate bricks is formed on the outer peripheral surface thereof with a flat portion for receiving the driving force for the relative reaction force at each of four locations arranged at angular intervals of 90.degree..
