FIELD: rolled stock production, possibly in mills for cold rolling of sheet steel.
SUBSTANCE: method comprises steps of guiding rolling and backup rolls into stand; providing common rotation of mutually forced rolling and backup rolls at simultaneously supplying onto rotating rolls cooling and lubricating liquid. Rolling rolls has normalized roughness degree of their surface Ra = 8.1 - 10 micrometers at using design diameter of backup rolls less than 50% and Ra = 6 - 8 micrometers at using design diameter of backup rolls more than 50%. Force of mutual forcing of rolls is set at level 35 -59% of maximally admissible value. Rolling rolls are driven to rotation till running value 4.0 - 12 km.
EFFECT: elimination of additional changes of damaged backup rolls, reduced idling time periods, enhanced efficiency of mill.
