FIELD: plastic working of metals, namely by rolling, possibly for making thin steel sheets.
SUBSTANCE: process for cold rolling of strip comprises steps of successive reduction of strip in stands of continuous rolling mill with tension between stands. According to invention in five-stand rolling mill tension of strip before third stand is set in such a way that it exceeds strip tension after said stand by 1.01 - 1.56 times. Tension of strip before fourth stand exceeds by 1.01 - 1.85 times tension after said stand. Tension after second stand exceeds by 1.01 - 1.04 times tension before said stand.
EFFECT: lowered vibration degree of rolling and backup rolls at rolling process.
