METHOD OF CONTROLLING TEMPERATURE ALONG STRIP WIDTH AT HEAT TREATMENT Russian patent published in 1997 - IPC

Abstract RU 2071991 C1

FIELD: metallurgy, namely, non-uniform heating of rolled metal at continuous heat treatment. SUBSTANCE: method comprises steps of continuously non-uniformly annealing moving strip by continuous induction heating in cross magnetic field with possibility of controlling non-uniformness of heating by selection of ratio of width values of inductor and strip. In order to receive softer mean portion ratio of width values of strip and inductor is selected higher than 1.45 and in order to receive softer edges the above mentioned ratio is selected less than 1.45. EFFECT: enhanced accuracy of controlling. 3 cl, 1 dwg
