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.

A segmental calendering device includes a framework, a pair of left-rolling sliding guide mechanism, a pair of right-rolling sliding guide mechanisms, an upper-calendering roller and a supporting mechanism of the upper-calendering roller, a lower-calendering roller as well as a pressing mechanism. The upper-calendering roller is rotatably supported within the supporting mechanism of the upper-calendering roller and disposed above a position between a left wallboard and a right wallboard of the framework, and the supporting mechanism of the upper-calendering roller slides along the pair of left-rolling sliding guide mechanisms and the pair of right-rolling sliding guide mechanisms. The lower-calendering roller is disposed below the upper-calendering roller correspondingly and rotatably supported between the left wallboard and the right wallboard. The pressing mechanism is for applying a pressure on the supporting mechanism of the upper-calendering roller and for adjusting the pressure.

There are provided a work-side position measurement device and a drive-side position measurement device for directly measuring positions of roll chocks in a rolling direction, and positions of upper and lower working rolls and upper and lower backup rolls in the rolling direction are adjusted to zero point or predetermined positions. Alternatively, a change caused in the strip wedge due to a minute crossing of the axes of working rolls and backup rolls is calculated, and the quantities of leveling of a work-side rolling reduction cylinder device and a drive-side rolling reduction cylinder device are adjusted to make the strip edge equal to or smaller than a predetermined value. Accordingly, the bilateral asymmetry (strip wedge) of the thickness distribution of a rolled material is easily adjusted even in the event that the positions of the roll chocks in the rolling direction are changed due to wear on various components.

The invention relates to a device 1 for positioning an edging roll 10 of an edging stand, comprising an edging frame 12 to which at least one balancing cylinder 14 is attached, a balancing crossbeam 16 with a drive side 18 positioned opposite of the edging frame 12, and a working side 19 positioned opposite of the drive side 18, wherein a bearing device 20 for the edging roll 10 can be attached, in particular in an interlocking manner, to the balancing crossbeam 16 on the working side 19 thereof and at least one linkage 24 is provided on the drive side 18 thereof, by which linkage the balancing cylinder 14 is in an operative connection with the balancing crossbeam 16, and at least one positioning cylinder 26 attached to the edging frame 12 can be brought into an operative connection with the bearing device (20) in the direction of a rolled material in order to position the edging roll 10 against the rolled material, wherein the compressive force generated by the positioning cylinder 26 acts on the bearing device 20 along an operational axis 28, which either intersects with the at least one linkage 24 by which the balancing cylinder 14 is operatively connected with the balancing crossbeam 16 or runs directly alongside this linkage 24.

An adjustment device for adjusting a roll in a roll support (13) of a roll stand includes a cylinder housing (2) that can be secured to a roll support (13), and a piston (1) guided to move translationally in and across the roll support. The position of the piston (1) can be determined via a travel measurement device (9) connected to a coupling rod (6) secured directly to the piston (1). The piston (1) has a guide element (3) extending from the piston head (4) into a bore in the roll rack and in the direction toward the travel measurement device (9). The coupling rod (6) is secured to the guide element (3). To reduce the sensitivity of the adjustment device to a tipping, the guide element (3) is guided in a guide opening (14) of the cylinder housing (2). A sliding guide (7) is provided for the coupling rod (6), which can be arranged on an end of a borehole (15) in the roll rack facing the travel measurement device (9).
