ABSTRACT:
A horizontal continuous casting system includes a tundish having a refractory lining and supporting a quantity of molten metal therein. The tundish supports a slide gate shut-off device. A rotating drum supports a plurality of interchangeable casting molds and is operatively coupled to a hydraulic motor through a linear bearing support. The motor is operative to rotate the drum and interchange the casting molds during brief casting interruptions facilitated by the slide gate shut-off. Each interchangeable mold in the plurality of casting mold includes an indexing flange defining a plurality of index recesses. A clamp stand is positioned downstream of the rotating drum and casting molds and supports a plurality of expandable hydraulic cylinders having extending index pins which cooperate with the index recesses and mold flange to secure a casting flange in place during the casting operation. The casting molds may be interchanged by retracting the extending pins using the hydraulic cylinders and rotating the rotatable drum to move an exhausted or defective mold out of the casting system and replace it with a new or refurbished casting mold.
