Method for producing a grain-oriented electrical steel strip or sheet intended for electrotechnical applications, comprising the following production steps: a) providing a thin slab having a thickness of 30 - 80 mm, which consists of a steel which contains, (in % wt.) Si: 2 - 6.5 %, C: 0.02 - 0.15 %, S: 0.01 - 0.1 %, Cu: 0.1 - 0.5 %, wherein %Cu/%S > 4 applies for the %Cu/%S ratio of the Cu content %Cu to the S content %S, Mn: up to 0.1 %, wherein in the presence of Mn, %Mn/%S < 2.5 applies for the %Mn/%S ratio of the Mn content %Mn to the S content %S, and in each case optionally N: up to 0.003 %, contents of acid-soluble Al of up to 0.08 %, wherein in the presence of Al, %N/%Al < 0.25 applies for the %N/%Al ratio of the N content %N to the Al content %Al, one or more elements from the group "Ni, Cr, Mo, Sn" with contents of up to 0.2 % in each case, one or more elements from the group "V, Nb" with contents of up to 0.1 % in each case, the remainder being iron and unavoidable impurities, b) homogenising the temperature of the thin slab to a slab temperature of 1000 - 1200 °C, c) hot rolling the thin slab into a hot strip having a thickness of 0.5 - 4.0 mm, wherein the hot-rolling initial temperature of the slab at the start of hot rolling is less than 1030 °C and the hot-rolling final temperature is at least 710 °C and both the first and the second hot-forming passes are carried out with a thickness reduction of at least 40 %, d) cooling the hot strip, e) coiling the hot strip into a coil, f) cold rolling the hot strip into a cold strip having a final thickness of 0.15 - 0.50 mm, g) decarburized annealing of the cold strip h) applying an annealing separator onto the surface of the annealed cold strip, i) final annealing of the cold strip provided with the annealing separator to form a Goss texture. a) providing a thin slab having a thickness of 30 - 80 mm, which consists of a steel which contains, (in % wt.)
