Abstract (en)

An improvement to the method of solidifying liquid metal in a casting wheel. The method consists in subjecting the metal (19), during solidification in the groove (2) of the wheel (1), to electromagnetic forces (20) of variable intensity and whose principal direction of action is parallel to the direction of displacement of the blank. The electromagnetic forces may be created by means of a sliding- field inductor (16, 17) or, more particularly, a linear motor placed above the strip (10, 11) which closes the groove in the zone where the metal is solidifying. This invention makes it possible to obtain blanks having a fine- grained structure and, if appropriate, which are free from segregations and porosities without having recourse to the addition of refining agents. <IMAGE>
