FIELD: metallurgy.
SUBSTANCE: metal strip head section 10 is rolled at rolling mill between top and bottom systems 2, 3 of rolling mill 1. Control over rolling comprises checking if tail section 11 of changeover station 12 located in direction of rolling (x) ahead of rolling mill 1. Ruling out of lateral microchipping of strip tail section is ensured by that, starting from the moment when tail section reaches changeover station, systems 2, 3 of rolls are bent by actuating mechanism 5 by force F that moves roll systems 2, 3 apart. Said force equals, at least, minimum force. Minimum force equals, at least, that of top roll system balancing. Said force is set subject to definite parameters of metal strip 4 rolling mil operating parameters.
EFFECT: higher quality of metal strip.
