A rolling mill stand has two working rolls forming a roll gap in which a rolled product transported in a conveying direction can be formed. The positioning of at least one working roll is variable in a plane perpendicular to the conveying direction. The rolling mill is used in a method which comprises: conveying the rolled product through the roll gap in the conveying direction and at the same time opening or closing the rolling mill stand by correspondingly increasing or decreasing the roll gap; during opening or closing of the roll stand, detecting a position of the rolled product in front of and/or behind the roll gap in the direction transverse to the conveying direction; and changing the positioning of the corresponding working roll depending on the detected position, so that the rolled product is stabilized at a target position during opening or closing of the roll stand.

Stabilization of the rolled product during opening and/or closing of a roll stand

A device and a method for rolling a metal strip. A distance of the upper/lower backup roll at at least one point thereof from a predetermined upper/lower reference point is measured by an upper/lower sensor and the measured values of the sensors are sent to a control device. A strain of the roll stand is calculated using a mathematical model, taking into account the rolling force generated. By the control device, an absolute value of the roll gap and thus the resulting thickness of the rolling stock is determined by the control device on the basis of the measured positions of the backup rolls and the calculated strain of the roll stand.

A flatness-measuring device for a hot-rolled strip within a hot-rolling mill includes an entry-side deflection roller and an exit-side deflection roller. A central deflection roller is arranged between the entry-side deflection roller and the exit-side deflection roller. The central deflection roller is used as a flatness-measuring roller. To prevent the hot-rolled strip from departing laterally during a flatness measurement, the flatness-measuring device has a sensing apparatus for sensing an actual position of the hot-rolled strip. An adjusting apparatus is connected to the sensing apparatus and to at least one of the deflection rollers. The flatness-measuring device is designed to vary an angle between a longitudinal central axis of the deflection roller respectively connected to the adjusting apparatus and a longitudinal axis of the flatness-measuring device based on a deviation of the actual position of the hot-rolled strip from a predefined target position.

A support roller, particularly for rolling mill systems or equipment for casting, conveying or straightening metal products, including a cylindrical roller axle, a hollow cylindrical outer ring arranged concentrically in relation to the roller axle, and a plurality of rolling bodies arranged between the roller axle and the outer ring. The roller axle further including a cavity, at least in certain sections between its central axis and a load introduction point. Due to the provision of the cavity the load rating and the service life of the support roller are increased.

A roller for a rolling mill with a casing, a left half pivot, and a right half pivot. The half pivots in the region surrounded by the casing are constructed as a truncated cone and form a left surface on the left half pivot and a right surface on the right half pivot. The left half pivot and the right half pivot have boreholes and corresponding grooves formed on the surfaces. The half pivots are inserted in the casing and are braced with one another by at least one tie rod. An hydraulic oil in boreholes and grooves is passed into or onto the left half pivot and the right half pivot. The hydraulic oil exerts a pressure on the casing to expand the casing. With the casing expanded, the stop surfaces and the face surfaces of the casing are pressed onto one another by the tie rod.

The invention relates to a roll stand for rolling a product, in particular made of metal, comprising a pair of first rollers contacted by a pair of second rollers supporting the first rollers, wherein the first roller and the second rollers have an asymmetrical radius curve (CVC grind) relative to a center plane, wherein the radius curve of the first rollers is represented by a polynomial of the third or fifth order. In order to design the wedging of a second roller supporting a first roller such that optimal operating conditions are set, the invention proposes that the radius curve of the second roller is given by a polynomial of the third or fifth order, wherein special relationships are prescribed for the ratios between the coefficients.

The invention relates to a method for calibrating a rolling stand (), wherein in order to determine the relative pivot position of the roller set for setting a symmetrical roll gap and/or for determining the extension of the rolling stand () before the actual rolling process, the roller set is pressed against each other under a radial preset force and the resulting deformation of the rolling stand is preferably measured on the piston-cylinder unit (). The pivot position of the roller set and/or the frame module (M) determined based thereon are mathematically used during the subsequent rolling of a rolling stock between the working rollers () for adjusting the roller set. In order to attain a higher accuracy during rolling, the invention provides for the working rollers () to be axially adjustable relative to each other starting from a zero position that is not axially displaced, wherein the determination of the pivot position for setting a symmetrical roll gap and/or the determination of the frame module (M) are carried out in a relative displacement position of the working rollers () that is not equal to the zero position (calibration position), wherein the determined pivot position and/or the value for the frame module (M) are stored and mathematically used for further calculating the pivot position and/or the adjustment of the roller set during rolling of the rolling stock.

When rolling hot-rolled strips, different draughts per pass might occur during the rolling operation over the length of the roll gap, due to changes in the hardness of the rolling stock, to the roll gap itself or to the geometry of the incoming rolling stock. These different draughts per pass lead to lateral deviations and shifts of the rolling stock in the roll stand and to a lateral bending of the outgoing hot-rolled strip. In order to avoid these defects by intentionally influencing the geometry of the rough-rolled strip, it is proposed to interconnect in at least one roughing-down stand a dynamic positioning in the roughing-down stock () with fast and powerful lateral guides () arranged before and after the roughing-down stand (), by corresponding regulation operations, in such a way that a grainy or tapering bloom () is shaped into a straight and taper-free roughed-down strip () in one or more passes, in continuous or reciprocating operation.
