The invention concerns rolling. A method of manufacturing metal strip by deformation by mill rollers includes heating slab and its continuous rolling in several stands. During rolling the plastic stretching of strip with uniform of lengthwise extended sections is simultaneously carried out in the inter-stand spaces by decrease of sizes of its section. In each stand, beginning from the second one, the speed of rolling is set in accordance with the ratio: where Vi and hi - speed and thickness of strip in the n-th stand, respectively; Vi+1 and hi+1 - speed and thickness of strip in (i+1) stand, respectively, and during rolling in each stand, beginning with the second one, the profile is formed of rectangular cross section with width (0.5 – 0.95) B, where B - width of slab.
