Patent

CA 2320124

The invention relates to a method for producing non-grain oriented electro sheet steel out of continuously cast slabs or thin slabs with low magnetic loss, high polarisation and good mechanical properties. The invention is characterized in that the steel slabs are hot-rolled directly after casting or after reheating to a temperature 900 ~C and in that during finishing rolling two or more deformation passes are carried out in the austenite/ferrite two- phase region.

L'invention concerne un procédé pour produire de la tôle électrique à grains non orientés, à partir de brames normales ou de brames minces coulées en continu et présentant une faible perte de démagnétisation, une polarisation élevée et de bonnes caractéristiques mécaniques. L'invention est caractérisée en ce que les brames d'acier sont laminées à chaud directement en sortie de coulée ou bien après un réchauffage jusqu'à une température T?900 ·C, et en ce que pendant le laminage final, au moins deux passes de formage sont réalisées dans le domaine biphasé austénite-ferrite.
