Abstract
Procédé utilisant deux bobines à courant alternatif et faisant intervenir dans le circuit électromagnétique des bobines la portion de paroi de la lingotière se trouvant au-dessus du bain. Sur la paroi 9 de la lingotière 1, le niveau du bain se tient dans la page 2. Deux bobines 3, 4, d'axes parallèles 11, 12, sont placées à une distance 13. La bobine 3, parcourue par un courant alternatif, produit un champ électromagnétique 8 qui induit dans la paroi libre 9, agissant comme circuit à spire unique 24, un courant produisant un champ électromagnétique 25 qui induit à son tour un courant dans la bobine 4. Les courants traversant les deux bobines sont appliqués à une commande 5 du niveau du bain.
