Abstract (en)

[origin: WO0138022A1] The invention concerns a method which consists in: simultaneously subjecting the meniscus of the molten metal present in the ingot mould to the action of an axial alternating electromagnetic field tending to provide it with a general dome-like shape and to the action of a transverse direct electromagnetic field designed to attenuate the surface agitation of the meniscus. The implementing installation comprises an ingot mould (1) with cooled assembled plates (2, 3 and 4, 5) for casting metal slabs, an alternating current coil (17) enclosing the ingot mould at the meniscus (12) of the molten metal to produce an axial magnetic field, collinear with the casting axis (11), and a direct magnetic field winding passing through the large plates of the ingot mould at the meniscus (12) perpendicular to the casting axis.
