Abstract

See full text

A method for producing a higher-strength, non-grain-oriented electrical strip, according to which a slab is cast from a molten mass, the slab is hot-rolled and then cold-rolled—optionally a hot-strip annealing can be carried out between the hot-rolling and the cold-rolling—and the cold strip is annealed in order to produce a partially recrystallized structure so that the mechanical strength values ReH can be set within the range of 450 MPa to 850 MPa at an annealing temperature of between 600° C. and 800° C. for 60 s to 300 s.
