Electromagnetic stirring process for continuous casting

摘要

An electromagnetic stirring process for continuous casting is presented. According to the present invention, coils of inductors are supplied with a multiphase current so as to create in a molten metal at least one primary rotational movement zone which is offset with respect to a central casting axis. This primary rotational movement zone is also revolved in a secondary gyratory movement around the central casting axis by a cyclic commutation of each phase of the current.
