A six-high rolling (also known as sexto) mill stand that is suited for hot rolling an intermediate strip into a thin strip that is less than 0.8 mm thick. A combined casting and rolling installation that includes the six-high rolling mill stand allowing for hot rolling in long uninterrupted sequences, without any change of the work rolls to obtain a strip with good geometry due to moderate rolling forces.

The invention concerns a 4-high/6-high/18 HS cassette-type roll stand in which bending force is transmitted to bending journals (6) of roll inserts (7) by piston-cylinder units that are connected with Mae West blocks (3). Here, the piston at the piston rod (1) is fixedly connected with the Mae West block (3) and the cylinders (4) fit around the bending journals (6) at the inserts (7) of the rolls, so that thereby bending force can be transmitted directly to the bending journals (6) of the roll inserts (7).

A roll stand for rolling a metallic product and having two work-rolls supported in the roll stand by respective work-roll chocks. An axial displacement arrangement is provided with which the work-rolls can be displaced in direction of their longitudinal axes, and at least one work-roll locking arrangement is provided with which the work-roll chocks can be locked and unlocked in the roll stand. A rotation prevention arrangement is provided with which the axial displacement arrangement can be prevented from rotation about longitudinal axes of the work-roll. A bending arrangement is provided which includes a bending block and with which a bending torque can be applied to the work-rolls. In order to achieve a simpler design of the assembly and improved lubrication possibilities for the component to be lubricated, the rotation prevention arrangement and the axial displacement arrangement are fixedly connected with the bending block.

An electrode rolling device acquires thicknesses of an electrode sheet, Tc at a center portion in a width direction, Twe at an end portion on a first side, Tde at an end portion on a second side, Twc at a first intermediate portion, which is set between the center portion and the end portion on the first side, and Tdc at a second intermediate portion, which is set between the center portion and the end portion on the second side. The electrode rolling device determines a deviation Twe between the thickness Tc and Twe, a deviation Twc between the thickness Tc and Twc, a deviation Tde between the thickness Tc and Tde, and a deviation Tdc between the thickness Tc and Tdc, and performs control so as to reduce the deviation Twe or Twc, whichever is larger, and to reduce the deviation Tde or Tdc, whichever is larger.

A hot rolling mill 1 includes a control apparatus 20 that adjusts an angle formed between an upper-side pair of an upper backup roll 120A and an upper work roll 110A and a lower-side pair of a lower backup roll 120B and a lower work roll 110B in a state where the upper-side pair is kept parallel and in a state where the lower-side pair is kept parallel. The hot rolling mill 1 is configured such that the work rolls 110A and 110B satisfy the condition that DW/Lb is equal to or smaller than 0.30 where DW is a diameter of the work rolls 110A and 110B, and Lb is the maximum strip width of a rolled material, and the hot rolling mill 1 performs rolling in a state where a bending force is applied to the work rolls.
