FIELD: metallurgy.
SUBSTANCE: invention relates to rolling. Method involves rolling a metal sheet using textured with electric discharge texturing roll, when metal sheet is at temperature from 250 to 970 degrees Fahrenheit, at which metal sheet has low yield strength compared to the yield point of metal sheet at ambient temperature. Device is equipped correspondingly.
EFFECT: possibility of correction of defects in sheet at various stages of rolling and facilitates performance of subsequent stages of rolling.
