Abstract

L'inducteur, utilisé pour le réchauffage inductif de produits métallurgiques, est du type inducteur à culasse magné­ tique en forme de C destinée à chevaucher le produit à réchauf­ fer et dont les extrémités libres forment des pôles magnétiques bobinés se faisant face. La culasse comporte deux branches polaires 24, 25 et deux biellettes 26, 27 intermédiaires, arti­ culées entre elles par une de leurs extrémités et articulées chacune respectivement sur une branche polaire par son autre extrémité, les trois articulations 3 ainsi formées étant d'axes parallèles. The inductor, used for the inductive heating of metallurgical products, is of the inductor type with magnified yoke C-shaped tick to overlap the warming product iron and whose free ends form magnetic poles wirewound facing each other. The cylinder head has two branches polar 24, 25 and two connecting rods 26, 27 intermediate, arti butted together by one of their ends and articulated each respectively on a polar branch by its other end, the three joints 3 thus formed being of axes parallel.

Cet inducteur est destiné au réchauffage de produits pouvant avoir des épaissseurs différentes, notamment de produits en défilement au cours de leur laminage. This inductor is intended for heating products may have different thicknesses, especially of products scrolling during their rolling.
