FIELD: rolled stock production, possibly in sheet rolling shops including continuous five-stand rolling mill and skin pass rolling mill whose rolling rolls have the same structure.
SUBSTANCE: exploitation of rolling roll comprises steps of alternating its operation in mill stands at regrinding and remounting as working layer of roll is spent. At first rolling roll is operated in skin pass rolling mill. When working layer of roll is spent no more than by 14%, roll is remounted to fifth stand of continuous five-stand rolling mill where roll operates until 15 - 28% of its working layer is spent. After that roll is remounted in second stand where it operates until its working layer is spent by 29 - 39%. Then roll is remounted to fourth stand of mill where it operates until 40 - 50% of its working is spent. Exploitation of roll is terminated in first stand of continuous five-stand rolling mill where roll operates until complete spending of working layer or till minimum design diameter of roll.
EFFECT: improved strength of rolling rolls, lowered specific consumption of rolls, reduced quantity of rejected cold rolled strips by surface flaws.
