The invention relates to a method for producing non-grain-oriented
hot-rolled magnetic steel sheet in which from a raw material such as cast
slabs, strip, roughed strip or thin slabs produced from a steel comprising
(in weight %) C: 0.0001-0.05%; Si: .ltoreq.1.5%; Al: .ltoreq.0.5%, wherein
[% Si]+2[% Al].ltoreq.1.8; Mn: 0.1-1.2%; if necessary up to a total of
1.5% of alloying additions such as P, Sn, Sb, Zr, V, Ti, N, Ni, Co, Nb
and/or B, with the remainder being iron and the usual impurities, in a
finishing roll line at temperatures above the Ar.sub.1 temperature, a hot
strip with a thickness .ltoreq.1.5 mm is rolled, wherein at least the last
forming pass of hot rolling is carried out in the mixed region
austenite/ferrite and wherein the total deformation .epsilon..sub.H
achieved during rolling in the mixed region austenite/ferrite is <35%.
With the method according to the invention, it is possible in particular
to economically produce thicker magnetic steel sheet which is not
grain-oriented and which has good magnetic properties.
