FIELD: metallurgy.
SUBSTANCE: performed are high-temperature annealing, curing, cooling to room temperature and processing in alternating magnetic field. In magnetic processing, strip plane deflects from magnetic field direction through 1° to 10° towards strip direction at magnetic field frequency of 0.05 to 1.0 Hz. Proposed method allows processing in continuous displacement of steel strip in process flow while strip angular deviation can be set by fitting guide rolls magnetothermal treatment furnace at different height.
EFFECT: improved magnetic properties of cold-rolled electric anisotropic steel.
