Abstract

L'invention appartient au domaine de la métallurgie et peut s'utiliser dans la fabrication d'acier électrotechnique anisotrope en bandes laminées à froid. Le procédé comprend le coulage de l'acier, sa distribution, son laminage à chaud, l'enlèvement des scories, deux laminages à froid séparés par un recuit intermédiaire visant à enlever le carbone et un recuit de redressement haute température, l'acier coulé comprenant en % en pds. 0,021-0,055 de carbone, 2,8-3,6 de silicium, 0,1-0,3 de manganèse, 0,4-0,6 de cuivre, 0,011-0,018 d'aluminium soluble dans l'acide, 0,007-0,012 d'azote le reste étant du fer et des impuretés inévitables. La température de laminage à chaud est sélectionné en fonction de l'équation suivante Tkcr={970-([ %C]-0,018) x 3000+([ %Si]-2,8) x 60}?20, °C, [ %C] and [ %Si] étant respectivement les concentrations de carbone et de silicium dans l'acier, en % en pds. Le procédé permet d'obtenir des valeurs élevées stables d'induction magnétique et des valeurs inférieures de pertes spécifiques d'acier électrotechnique, qui permettent de l'utiliser dans la construction de transformateurs de distribution ou d'alimentation.
