摘要： A rolling mill has a rolling stand (1) in which a flat rolled product (2) composed of metal is rolled. A sensor device (6), which detects at least one measured variable (M) characteristic of a material property of the flat rolled product (2), is arranged upstream and/or downstream of the rolling stand (1). The material property can be, in particular, an electromagnetic property or a mechanical property of the rolled product (2). The sensor device (6) transfers the detected measured variable (M) to a control device (9) for the rolling mill. Taking into account the measured variable (M), the control device (9) determines a control value (A) for the rolling stand (1). The control of the rolling stand (1) influences the material property of the flat rolled product (2). The control value (A) is a ratio of the peripheral speeds (vO, vU) at which the upper and the lower working rolls (3, 4) of the rolling stand (1) rotate.

摘要： A method and apparatus for automatically controlling the gauge of metal strip rolled in a tandem strip mill. Load cells installed on a first stand generate signals representative of changes in the roll-separating force, and hence of gap error, at this stand. Such signals are fed-forward, with a delay to allow for transport time of the strip minus screw-reaction time, to a second stand to effect screw adjustment of the latter. Signals representative of gap error at the second stand, corrected for changes in the position of the screws at the second stand, are fed-forward to effect screw adjustment at a third stand, etc. The screws of the first stand are maintained at their original setting, while adjustments in the screws of succeeding stands made in response to changes in the roll-separating force are effected exclusively by signals fed-forward from a preceding stand.The invention also includes an improved method and apparatus for delaying transmission of analog signals for controlled intervals without need for converting the analog signals to digital signals.

摘要： When the tracking point reaches the i-th stand, the continuous rolling system outputs, to an i-th stand, a roll gap operation value for bringing to zero a difference between a value which is obtained by correcting a strip thickness target value of the i-th stand with a target strip thickness correction value of the i-th stand and a value which is obtained by correcting a strip thickness actual recalculation value of the i-th stand with a gap correction value of the i-th stand. Here, the gap correction value is a correction value that brings to zero a difference between a head end gap error when a head end of the material to be rolled reaches the i-th stand and a non-head end gap error when a part other than the head end of the material to be rolled reaches the i-th stand.

摘要： In thickness control processing, transfer processing of an entry thickness He(N) is performed (step S1). In the transfer processing, data of the entry thickness He(N) is transferred from a position P11 to a position P12 at the same speed as the speed of a material to be rolled M. Subsequently, an amount of change in a thickness ΔH(N) is calculated (step S2). The amount of the change in the thickness ΔH(N) is calculated based on data of a delivery thickness Hd(N) and data of a transferred thickness Hc(N) transferred to the position P12 at a timing when the data of the delivery thickness Hd(N) is measured. Then, a target entry thickness He(N)_tgt is calculated (step S3). Subsequently, a manipulated amount of rolling speed VR(N−2) and VR(N−k) are calculated (step S4).

摘要： In a method of rolling metal for producing a metal plate or a metal sheet having a desired range of thickness through a sequence of rolling passes, variations in the deformation resistance of the metal along the longitudinal direction of the metal are detected, variations in deformation resistance and the resulting variations in rolling force in the finishing pass are estimated, and the rolling for obtaining the necessary thickness of the metal at the entrance of the finishing pass is carried out under a combination of a feedback automatic gauge control process and feed-forward automatic gauge control process, whereby variations in the rolling force are cancelled even if the metal which is to be rolled has skid marks thereon.
