Abstract
An electromagnetic stirrer for stirring the molten core of a continuously cast strand has a casing. The casing accommodates a body of oil as well as electromagnetic stirring coils which have respective magnet cores and are immersed in the oil. A system of cooling pipes extends into the oil and has water inlets and water outlets. The stirrer may be constructed as a unit with a continuous casting mold and, in such an event, the water inlets are connected to a source of mold cooling water while the water outlets function to discharge or recycle the water. Alternatively, the stirrer may be disposed in the secondary cooling zone. Here, the water inlets are connected to a source of secondary cooling water for the strand and the water outlets are in communication with spray nozzles which serve to spray the strand with the secondary cooling water.
