Abstract RU 2071990 C1

FIELD: heat treatment of rolled strips and other rolled metal. SUBSTANCE: method comprises continuous non-uniform heating of moving strip. Novelty is in steps of additional rolling after heating and performing heating in cross magnetic field of inductor; setting such ratio of width values of inductor and strip that provides higher temperature heating of mean portion of strip relative to its edges, for example, selecting the above-mentioned ratio more than 1.45. EFFECT: enhanced quality of strip after heat treatment. 2 cl, 1 dwg
