Abstract

L'invention concerne un procédé pour produire un acier au silicium électromagnétique ayant une orientation à structure cubique sur arêtes et une perméabilité d'au moins 1870 (G/Oe) à 10 oersteds, ainsi que les aciers obtenus. Ce procédé comporte la préparation d'une charge fondue d'acier au silicium contenant 0,02 à 0,06 % de carbone, 0,0006 à 0,008 % de bore, jusqu'à 0,01% d'azote, au plus 0,008 % d'aluminium et 2,5 à 4,0 % de silicium, la coulée de l'acier, le laminage à chaud de l'acier, le laminage à froid de l'acier, la décarburation de l'acier, l'application d'un revêtement d'oxyde réfractaire contenant du bore et du SiO2 et le recuit de texturisation finale de l'acier. L'acier ainsi obtenu convient en particulier pour la réalisation des circuits magnétiques feuilletés.The invention relates to a process for producing an electromagnetic silicon steel having a cubic structure orientation on edges and a permeability of at least 1870 (G / Oe) at 10 oersteds, as well as the obtained steels. This process involves preparing a molten charge of silicon steel containing 0.02-0.06% carbon, 0.0006-0.008% boron, up to 0.01% nitrogen, not more than 0.008 % aluminum and 2.5 to 4.0% silicon, steel casting, hot rolling of steel, cold rolling of steel, decarburization of steel, application of a refractory oxide coating containing boron and SiO2 and the final texturizing annealing of the steel. The steel thus obtained is suitable in particular for making laminated magnetic circuits.
