    • A rolling mill (32) has a hydraulic roll-gap control system (66) for setting the roll gap between two work rolls (3, 4) of the rolling mill and a mill modulus control unit (54) for supplying a correction signal (C p ) to the hydraulic roll-gap control system based on the difference between a reference rolling pressure and the actual rolling pressure during rolling detected by a load cell (1). The rolling mill includes a thickness control system on at least the entry side of the rolling mill including a tension controller (33) which comprises means (35) for applying a force to the workpiece (30) in the direction of its thickness, that is to say perpendicular to the plane of the workpiece, means (37) for producing a signal (T) indicative of the tension in the workpiece, means (45) for comparing the said signal (T) with a reference signal (T ref ) and producing a different signal (ΔT) and means (40, 42) responsive to the different signal and arranged to control the force-applying means (35) to vary the tension in the workpiece so as to reduce the value of the different signal, i.e. maintain the tension substantially constant.

    • PURPOSE:To prevent the bad influence caused by roll eccentricity and to improve the flowability of a material and the accuracy of its sheet thickness by measuring directly the sheet thickness at the middle between stands and controlling the sheet thickness basing on the measured value. CONSTITUTION:A notch or a through hole 11 is formed in the arm of a looper 10 in order to measure the sheet thickness of a steel sheet 12 directly between narrowly spaced rolling stands. A gamma radiation source 13 is provided to one side and a scintillator 14 is provided as a radiation detector to the other side, for instance, along the center line of the hole 11 by interposing the sheet 12 of measuring object as a boundary between them. The sheet thickness is measured by such a sheet thickness measuring device to obtain the real sheet thickness by correcting the measured value basing on a looper angle theta. In a rolling mill having No.1-No.7 stands, for instance, the thickness is measured at the outlet side of No.4 stand by said thickness gauge 3, and the measured value is fed back to the upstream stand through the former of feedback control device 20A, 20B. At the same time, the thickness at the outlet side of No.7 stand is fed back to No.5-No.7 stands through the device 20B.
    • 目的:为了防止由辊偏心引起的不良影响,通过直接测量机架之间的中间的板厚度,并根据测量值控制板厚,提高材料的流动性和板厚的精度。 构成:在弯针10的臂上形成切口或通孔11,以便直接在窄间距的轧制机架之间测量钢板12的板厚。 伽马辐射源13被提供到一侧,并且将闪烁体14作为放射线检测器设置成另一侧,例如沿着孔11的中心线,通过插入测量对象的片12作为它们之间的边界。 通过这样的片材厚度测量装置测量片材厚度,通过基于打孔角度θ校正测量值来获得真实的片材厚度。 例如,在No.1号机架的轧机中,在厚度计3的4号机架的出口侧测量厚度,通过前者将测量值反馈到上游侧 反馈控制装置20A,20B。 同时,通过装置20B将No.7支架出口侧的厚度反馈到No.5-No.7。
