Abstract (en)

[origin: CA2005816A1] In a process for electromagnetic casting of round and hollow ingots, in particular such of aluminum and aluminum alloys, the ingot (7) is rotated about its longitudinal axis (x) during casting. This is achieved by way of a rotatable dummy base (6). With that the metal feed and cooling of the ingot is made symmetrical and, as a result, a more uniform shape is obtained and a more uniform cell structure across the ingot cross-section. In order to promote a stronger stirring effect, a stationary stirrer (8) dipping into the molten part of the ingot (7) can be provided attached to the metal inlet system (3). (figure 1).
