Abstract
Abstract A continuous casting machine is provided with a casting position and at least one preparation position. At least two molds are provided, with each mold connected to a section of a roller apron to form a mold unit which is so mounted that it is movable as a unit between the casting position and a preparation position and vice versa. While metal is being cast through one mold unit at the casting position, the other mold unit at a preparation position may be prepared for use in the next casting operation, including insertion of a dummy bar. When the mold unit is at the casting position, the movable section of the roller apron is aligned with a fixed section of the roller apron, so that the two sections form a continuous guideway for the casting leading to withdrawal rollers.
