Abstract
A sliding rotary nozzle assembly for pouring of molten steel has a bottom plate brick and a sliding plate brick, with these plate bricks being arranged as dual doors that may be opened and closed as desired relative to a base plate that includes a flow nozzle. Each of the brick plates is provided with plural nozzle openings and is carried for rotation with the bottom plate brick being positioned on top of the sliding plate brick when the doors are closed. In case of damage to nozzle opening of the rotary bottom plate brick, the dual doors are opened and the bottom plate brick is then rotated to bring the remaining nozzle opening to the use position to make best use of the bottom plate brick and prolong the service life of the nozzle assembly.
