FIELD: strip cold rolling in rolling stand provided with device for setting gap between rolls, with unit for uncoiling strip before rolling stand and unit for coiling strip after rolling stand.
SUBSTANCE: in rolling mill between unit for uncoiling strip and rolling stand there is strip accumulator for controlling mass flows and strip tension at rolling strip whose thickness is continuously changed according to preset profile. Strip accumulator includes movable roller mounted with possibility of controlling its position with use of regulator of force of its driving apparatus. Roller position is controlled at taking into account preset value of force received from measured actual angular movement of movable roller and predetermined value of strip tension and also profile of strip thickness change.
EFFECT: possibility for stabilizing rolling process due to stable strip tension at changed profile of strip thickness, increased speed of rolling process.
