Abstract RU 2692136 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy. Steel sheet is held in temperature range of 1,000 °C or more and 1,120 °C or less for 200 seconds or less, and then held in a temperature range of 650 °C or higher and 1,000 °C or lower for 200 s or less during annealing to final cold rolling, and amount of Al in emissions after annealing to final cold rolling is limited to 50 % or more total amount of Al contained in steel slab.

EFFECT: improved and stabilized magnetic properties.
