SUBSTANCE: method comprises steps of rolling (after predetermined rolling pass) with higher reduction degree for one pass on leading end of strip in comparison with rear end of strip; normalizing difference of reduction values. It provides elimination of large difference values of rolling efforts at relatively small final thickness values between leading and rear portions of strip during last rolling passes.
