FIELD: plastic working of metals. ^ SUBSTANCE: method comprises steps of calculating current value of coil diameter at coiling-uncoiling process according to relation of revolution numbers of mill rolls and coiler; according to calculated value setting revolution number of motor of coiler and its electromagnetic parameters; at coiling counting turns of strip in coil simultaneously with calculation of current value of coil diameter; for each turn of coil storing diameter of coil calculated at such time moment; at next uncoiling of coil, counting turns in reverse direction; using stored value of coil diameter of respective turn for setting revolution number of coiler motor and its electromagnetic parameters. ^ EFFECT: enhanced accuracy of controlling tension of strip due to elimination of influence of reduction change in stand upon calculation accuracy of coil diameter at uncoiling strip. |
