METHOD FOR MAKING COLD ROLLED ELECTRICAL ANISOTROPIC STEEL Russian patent published in 2002 - IPC

Abstract RU 2180356 C1

FIELD: ferrous metallurgy. SUBSTANCE: method for making cold rolled strip of electrical steels with texture (110)[001], namely making steel with AlN-phase as inhibitor of standard growing of grains after hot rolling of strip or only after cold rolling comprises steps of additional treatment for enlarging grain structure; after hot rolling or only after cold rolling with small deformation degree subjecting strip to additional annealing in hood furnace at 750- 900 C. EFFECT: high stable magnetic properties of electrical anisotropic steel due to optimal combination of technological processes important for formation of texture and inhibitor phase. 4 cl, 3 tbl
