METHOD FOR SKIN PASS ROLLING OF ROLLED THIN SHEETS Russian patent published in 2001 - IPC

FIELD: rolled stock production, namely, skin pass rolling of cold rolled sheet iron. SUBSTANCE: method comprises steps of rolling with small reduction values in such a way that at temperature of skin pass rolled metal lower than 45 C, reduction values are equal to 0.5-2.2%, at temperature 45-75 C - to 0.5-1.5% and at temperature 75-90 C - to 0.5-0.8%. EFFECT: enhanced efficiency due to lowered time period for cooling before skin pass rolling and increased temperature of skin rolled metal while keeping all mechanical properties of metal. 1 tbl
