摘要： PURPOSE:To detect accurately a tension of strip at the wrapping part of roll and to prevent various kinds of troubles due to abnormal tensions, by detecting a horizontal force acting on a strip-wrapped work roll and subtracting a horizontal force produced by rolling from said horizontal force. CONSTITUTION:A strip (s) is rolled, by passing it through the 1st-3rd gaps 21-23 in sequence, and rotating respective rolls 1-4 at their prescribed speeds in a state of wrapping the strip (s) around the 2nd and 3rd work rolls 2, 3 as well as rolling it by adding the prescribed rolling down forces respectively. Horizontal forces F, F' acting on roll chocks 2, 3 in the inlet and outlet sides directions respectively, are detected by load cells 10, 15 because the forces F, F' are produced by the inlet and outlet tensions acting on the strip (s). On the other hand, a rolling force P is detected by a load cell 16, and a horizontal force Fp is obtained by using a prescribed equation based on the previously inputted values with the aid of a computing unit 17. A computing unit 18 subtracts Fp from F to obtain the inlet tension T1b of sheet (s) during rolling. In the same manner, an outlet tension T3f is obtained, to control each of roll- driving system and rolling down force, etc. based on these tensions.
