ABSTRACT:
A system for controlling interstand tension of a tandem rolling mill includes a detector for directly detecting a travelling speed of a work between two neighboring stands. A value of a speed of the work thus obtained is processed by a tandem rolling controlling section together with a value of a load and another value of a rotational speed of rolls. A rotational speed of the rolls is thus determined in accordance with a result of the process.
