摘要： 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.
