Continuous metal casting apparatus has an electromagnetic stirrer for molten metal remaining in the cast strand leaving the mold, the stirrer being housed in a water-cooled hollow walled shell having a front wall facing the strand and provided with spray nozzles in an array patterned depending on whether the strand is straight or curved. This wall has been an integral part of the shell, the shell's water supplying the nozzles. To permit the same stirrer and shell to be used for both straight and curved strands, a face plate is made as a separate part removably fastened to the front wall, permitting other plates to be provided for interchange, the plates respectively having arrays of nozzles differently contoured to accommodate straight or curved strands. A frame fixed to the front wall and to which the face plate is removably fastened, forms a manifold space behind the plate and open to the front wall's openings in which the nozzles were formerly positioned, the face plate nozzles being thereby supplied with the water cooling the shell.
