Title (EN) NON-ORIENTED ELECTRIC STEEL PRODUCED BY THIN SLAB CONTINUOUSLY CASTING AND ROLLING AND PRODUCING METHOD THEREOF
(FR) ACIER ÉLECTRIQUE NON ORIENTÉ PRODUIT PAR COULÉE CONTINUE DE BRAMES MINCES ET LAMINAGE ET SON PROCÉDÉ DE PRODUCTION
(ZH) 薄板坯连铸连轧生产的无取向电工钢及其方法
Abstract: front page image
(EN)A non-oriented electric steel comprises, in weight percentage, C≤0.008%,Si:0.15~2.2%,A1≤0.008%, Mn0.15~1.5%, P0.004~0.15%, S≤0.008%,[O]≤ 40 PPm, N≤0.005%, Ti≤0.008%, balance Fe and unavoidable impurities. A method for producing the non-oriented electrical steel is also provided, which comprises the following steps: smelting in converter and treating in vacuum, continuously casting into plate blank with thickness of 50-90mm, soaking in a tunnel furnace, continuously rolling with seven-roller mill, coiling, pickling, cold rolling, re-crystallization annealing and standby.
(FR)L'invention porte sur un acier électrique non orienté comprenant, en pourcentage en poids, 0,008 % ou moins de C, 0,15~2,2 % de Si, 0,008 % ou moins d'Al, 0,15~1,5 % de Mn, 0,004~0,15 % de P, 0,008 ou moins de S, 40ppm ou moins de [O], 0,005 % ou moins de N, 0,008 % ou moins de Ti, le reste étant du Fe et des impuretés inévitables. L'invention porte également sur un procédé pour la production de l'acier électrique non orienté, qui comprend les étapes suivantes : la fusion dans un convertisseur et le traitement sous vide, la coulée continue en un flan de tôle ayant une épaisseur de 50-90 mm, le maintien à température dans un four tunnel, le laminage continu avec un laminoir à sept rouleaux, le bobinage, le décapage, le laminage à froid, le recuit de recristallisation et la mise en attente.
