METHOD FOR CONTINUOUS COLD ROLLING OF STRIP WITH TENSION Russian patent published in 2004 - IPC

Abstract RU 2239500 C1

FIELD: rolled stock production, possibly in continuous wide strip cold rolling mills.

SUBSTANCE: method comprises steps of determining in each interval between stands yield limit ς_y of strip; keeping value ς_t of specific tension by setting coefficient n_ς equal to relation ς_t/ς_y; performing rolling process at setting admissible value of coefficient n_ς = n_ς_prel ≤ 0.25; increasing specific tension values in intervals between stands from first to last one by average value 1 - 2 kg/sq. mm; lowering reduction value after second stand by 1 - 5% in each stand until last one; setting bulges of rolling rolls in stands in range (-0.10) - (+0.25)mm.

EFFECT: enhanced quality of cold rolled strips.
