<p>The invention concerns an electromagnetic equipment comprising an inductor (10) enclosing the ingot mould and placed at the meniscus (7) of the cast metal to generate an axial alternating current magnetic field, said field being associated with a transverse direct current magnetic field generated by an electromagnet (20) whereof the magnetic poles (21, 22), located behind the two large sides (3, 3') of the ingot mould, face each other on either side of the cast product at the level of the meniscus likewise. The inductor generating the axial alternating current magnetic field consists of two linear conductors (11, 11') mechanically independent of each other, and arranged each along the width of each large size (3, 3') of the ingot mould, between said large side and one of the poles (21, 22) of said electromagnet (20). Such an equipment, designed to stabilise a meniscus (7) in a marked convex shape, enables the width of the cast semi-finished products to be modified.</p> |
