METHOD FOR PRODUCING A MAGNETIC GRAIN ORIENTED STEEL SHEET WITH LOW LEVEL LOSS BY MAGNETIC REVERSAL AND HIGH POLARISATION

The invention relates to a process for the production of grain--oriented electric quality sheet by melting a silicon steel and casting the melt continuously into a strand having a thickness of 25-100 mm. During solidification the strand is cooled to a temperature above 700.degree.C and divided into thin slabs. The thin slabs then pass through an equalisation furnace standing in line where they are reheated to a temperature .ltoreq. 1170.degree.C and continuously rolled in a multi-stand hot rolling mill to give hot strip having a thickness of .ltoreq. 3.0 mm. The first shaping pass is performed at a temperature in the rolling stock up to 1150.degree.C. The reduction in thickness is at least 20%. The hot strip is cold rolled in one or more stages with recrystallising intermediate annealing to a final thickness in the range of 0.15 - 0.50 mm. The cold strip is then annealed with recrystallisation and decarburisation, furnished with a predominantly MgO-containing annealing separator and given a final annealing for imprinting a Goss texture. The strip is then coated with an electric insulation and given a stress-free annealing.
