The apparatus sprays the sides and lower end of the tundish with refractory material. The apparatus comprises a nozzle having an inlet and an outlet, and a base movable in an x direction generally horizontally along the tundish, a boom movable in a vertical y direction, a lance movable in a z direction generally perpendicular to the x and y directions, and a rotatably swivel bracket for rotating the nozzle outlet about an axis extending in the y direction. The apparatus also includes piping for supplying fluidized refractory material to the nozzle inlet, and a water ring for wetting the fluidized material before the nozzle outlet.
