    Abstract: The invention relates to a method for adjusting the rolls (1, 2, 3, ) of a roll stand (5), wherein the roll stand (5) comprises at least two interacting working rolls (1,2), wherein one of the working rolls (1) is arranged in the roll stand (5) in a displaceable manner for adjusting a roll gap, and wherein the other working roll (2) can be rotated in the roll stand (5) in a working position, but for defining a passline (p) in the direction normal to the surface of the roll material is fixed in a non-displaceable manner. In order to increase the rolling accuracy, the invention proposes the following steps: a) determining the position (Sist) of the working roll (2) arranged in a fixed manner in the roll stand (5); b) comparing the determined value (Sist) of the position to a target value (Ssoll); c) adjusting the working roll (2) fixedly arranged in the roll stand (5) depending on the comparison value determined in step b) using at least one adjusting element (6) such that the position (S) of the working roll (2) fixedly arranged in the roll stand (5) at least largely reaches the target value (Ssoll). The invention further relates to a roll stand comprising at least two interacting working rolls.

    Abstract: The object is to eliminate the difference in offset of work rolls at the upper and lower and left and right of the rolling mill occurring in the kiss roll state of the zero point adjustment work before rolling or during rolling and eliminate the problem of warping of the flat products or meander or camber due to the thrust force acting between the work rolls and backup rolls.For this, there are provided a rolling mill for flat products having a pair of upper and lower work rolls driven by electric motors, a pair of upper and lower backup rolls contacting the work rolls and supporting the rolling reaction force applied to the work rolls, and devices for applying substantially horizontal direction external forces to the upper and lower work rolls, the rolling mill for flat products characterized in that a direction of horizontal direction external forces applied to the work rolls is the same direction as the horizontal direction force component of the rolling reaction force applied to the work rolls due to the rolling direction offset and in that the horizontal direction external forces applied to the work rolls are supported by rolling mill housing project blocks or work roll chock support members, and a rolling method for flat products using the same.

    Abstract: A 6-high rolling mill has work rolls which have offsets, relative to the intermediate rolls, such that during operation there is a net horizontal force acting to urge the work rolls into engagement with the support rolls whereby substantially all horizontal support of the work rolls is provided by the support rolls. Support pads are located proximal the rolls' side faces, without exerting any substantial force on the work rolls during operation.

    Abstract: There are provided a rolling machine and a rolling method in which the strip crown and shape control capability for a narrow-width strip is improved, so that the adequate strip crown and shape control capability for strips of various widths from a narrow width to a larger width can be secured. In the rolling machine, a pair of upper and lower working rolls are supported respectively by a pair of upper and lower intermediate rolls, and the intermediate rolls are supported respectively by a pair of upper and lower reinforcing rolls. The reinforcing rolls have an effective barrel length which is smaller than an effective barrel length of the working rolls and the intermediate rolls, and is larger than a width of a minimum-width strip to be rolled. The intermediate rolls are arranged in such a manner that their axes, disposed respectively in substantially horizontal planes, cross each other, and are crossed relative to the working rolls and the reinforcing rolls. The maximum cross angle of the intermediate rolls are increased and decreased in accordance with the width of the strip.

    Abstract: The invention relates to a control process for a roll stand consisting of a pair of work rolls, a pair of backup rolls, and optionally a pair of intermediary rolls. The controls for a rolling force, a deflecting force, and optionally a roll shift are given specified values, which are obtained on-line in a roll stand model with a roll deflection model. According to the invention, relationships between the rolling force, the deflecting force, and the roll shift, on the one hand, and a corresponding roll gap variation on the other hand are determined on line in the roll deflection model at interpolation points. These relationships are used to calculate at the interpolation points set points for the rolling force, the deflecting force, and the roll shift.
