An apparatus for the continuous casting of slabs has a mold and a slab support zone immediately following the mold. The mold is made up of four separate plates which are held together to define a mold cavity. A dividing wall can be removably mounted in the mold cavity in order to divide the same into a pair of parallel casting passages. Insertion of the dividing wall in the mold cavity makes it possible to simultaneously cast two relatively narrow slabs rather than a single wide slab. A partition designed to constitute an extension of the dividing wall is provided for the support zone and can be removably mounted in the same. Both the dividing wall and the partition are carried by a clamping mechanism which serves to clamp the dividing wall in the mold cavity. The clamping mechanism, which is designed to be mounted on the mold externally of the mold cavity, may be in the form of a frame which circumscribes the mold or may consist of two discrete clamping devices one of which carries the dividing wall and the other of which carries the partition. In the latter case, the clamping device with the partition is mounted at the end of the mold nearest the support zone while the clamping device with the dividing wall is mounted at the opposite end of the mold. The dividing wall has one or more cooling ducts and the clamping mechanism is formed with one or more passages which communicate with the ducts and can be connected to a source of cooling fluid. The partition is provided with spray nozzles for slab cooling and the clamping mechanism is further provided with at least one additional passage for establishing communication between the nozzles and a cooling fluid source.
