    Abstract: A method and device for controlling the final thickness of a rolled product at a tandem rolling mill exit which make it possible to remove the cyclic defects of the product thickness variation. The method includes using at least one rolling stand provided with hydraulic adjustment devices located on the tandem rolling mill exit and in compensating the cyclic defects of the product thickness variation generated upstream through the entire rolling mill on the stand with the aid of an adjuster (R) coordinated with the frequency of defects. The method and device are suitable for tandem cold rolling mills producing metal strips. The thickness defects are detectable by a thickness sensor.

    Abstract: 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).

    Abstract: Systems and associated methods for controlling roll steering during rolling of a metal substrate may include a steering control actuator adapted to control an inclination of a work roll of a work stand of the rolling mill, a sensor configured to measure a parameter of a metal substrate upstream from the work stand, and a controller operably connected with the steering control actuator and the sensor. The controller may generate a model for the work stand and determine an adjustment value for the work stand, receive the measured parameter from the sensor, and determine an expected output parameter by adjusting the measured parameter by the adjustment value. The controller may also compare the expected output parameter with a target output parameter and actuate the steering control actuator such that the expected output parameter is within a predefined tolerance of the target parameter.

    Abstract: A wedge setup/control method for plate material rolling ensures that the work side and drive side are equal in the rolled plate thickness. The wedge setup/control method, which is used in reversible rolling of a plate material with a rough mill for hot rolling, includes preparing a wedge meter on the outlet side of the rough mill to measure the plate thickness in the direction of the plate width; performing calculations on a wedge measured by the wedge meter, using the influence coefficient of the wedge for roll gap leveling of the rough mill; determining amount of roll gap leveling control; and exercising feedback control to apply the amount of roll gap leveling control to the roll gap leveling of the rough mill.

    Abstract: 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.
