Two tundish cars, each detachably carrying a tundish, are supported on continuous circular rails for movement between a pouring position and a standby position spaced along the rails from a pouring position and provided with guide rails mounted above the circular rails and extending radially outwardly therefrom to a slag discharge position and to tundish reconditioning apparatus, both spaced radially outwardly of the circular rails. A shuttle truck moveable along the guide rails and provided with a hoist, lifts a tundish from its car in the standby position, transports the lifted tundish to the slag discharge position, to the reconditioning apparatus, and returns the emptied, reconditioned tundish to its car.

Tundish exchange apparatus for a continuous casting equipment

Two tundish transport trucks move in alternate relation between a pouring position and a tundish preheating position. A swivel table is disposed at the forward end of a transport rail which extends laterally from the pouring station for guiding the tundish transport truck for movement thereon. Provided on the swivel table are a pair of swivel rails such that one of the rails is connected to the travel rail and the other is positioned in corresponding relation to a tundish preheating device. When the swivel table turns with the tundish transport trucks mounted on corresponding swivel rails, a preheated tundish is delivered to the pouring position and a used tundish is subjected to repair and preheating so as to be ready for a next tundish changing operation.
