Title (EN) PROCESS AND DEVICES FOR THE INDUCTION HEATING OF A MOVING ELONGATE METALLURGICAL PRODUCT
(FR) PROCEDE ET DISPOSITIFS DE RECHAUFFAGE PAR INDUCTION AU DEFILE D'UN PRODUIT METALLURGIQUE DE FORME ALLONGEE
Abstract:
(EN) The product (11) moves in the direction (12) of its axis in relation to at least one magnetic inductor (10, 10'). The metallurgical product (11) is subjected to at least two magnetic fluxes (19, 19') having non-parallel transverse directions in relation to the product's longitudinal direction (11). The heating device can advantageously consist of two C-shaped magnetic yokes (14, 14') spaced and angularly offset in the axial direction (12) of the moving product.
(FR) Le produit (11) est en déplacement relatif dans la direction (12) de son axe par rapport à au moins un inducteur magnétique (10, 10'). On soumet le produit métallurgique (11) à au moins deux flux magnétiques (19, 19') ayant des directions non parallèles transversales par rapport à la direction longitudinale du produit (11). Le dispositif de réchauffage peut être constitué de manière avantageuse par deux culasses magnétiques (14, 14') en forme de C espacées et décalées angulairement suivant la direction axiale (12) de défilement du produit (11).
