FIELD: rolled stock production, namely processes for making cold rolled strip steel.
SUBSTANCE: method comprises steps of restoring surface of roll after skin pass rolling of predetermined number of strips. According to invention rolling rolls having chrome plated surface after rolling Q of metal including no more than 2/3 Q of strips with minimum width are mounted without mutual gap and between rotating rolls spindle oil heated up to 50 - 80°C is passed. Then skin pass rolling is realized successively from wide strips to narrow ones.
EFFECT: high quality of roll surface cleaning without damaging their chrome plated surface.
