The mould comprises a copper mould at least partly surrounded by a cooling box in which a cooling fluid flows. The cooling box comprises a first chamber defined by the copper wall of the mould and by a parallel front wall of the box. This front wall includes magnetic poles which are part of an electromagnetic induction stirring device for the metal cast in the mould. The first chamber is connected to a first cooling circuit. The box also has a second chamber in which the coils and cores of the electromagnetic induction stirring device are disposed.

Continuous-casting mould provided with an electromagnetic stirring device

A process and installation for stirring metal in a continuous-casting mould by forming in the ingot mould an electromagnetic induction field rotating about an axis parallel to, or coinciding with, the axis of the ingot mould by means of a stator supplied with alternating inducting current. According to the invention, the liquid metal surrounded by a ring of solidified metal and the copper ingot mould is driven in rotation by employing a field produced by an inducing current of frequency lower than 10 Hz.
