FIELD: rolling.
SUBSTANCE: invention relates to a method for changing the effective circuit of the working surface of the working roll during hot rolling of the rolled material in a rolling mill to obtain a rolled strip. Hot rolling of the rolled material is carried out between two working rolls. At the same time, the radial length of the working surface of the working roll is reduced during rolling. Axial displacement of the working rolls in opposite directions to the displacement path is provided, which is calculated according to the mathematical expression given in the formula of the invention.
EFFECT: possibility of changing the circuit of the working surface during hot rolling.
