METHOD FOR SHAPE CONTROL IN ROLLING MILL AND DEVICE FOR SHAPE CONTROL IN ROLLING MILL
A method for shape control in a rolling mill includes: a measurement step of measuring a shape of a steel sheet on a delivery side of the rolling mill; and a control step of controlling the rolling mill in a manner that the shape of the steel sheet falls within an allowable range, based on the shape of the steel sheet measured at the measurement step, wherein the control step includes a step of setting a control gain smaller than a control gain for a width of a steel sheet as a target for rolling being equal to or smaller than the predetermined value when the steel sheet as the target for rolling has a width greater than a predetermined value.
SIX-HIGH ROLLING MILL STAND AND FINISHING MILL TRAIN FOR HOT ROLLING AN INTERMEDIATE STRIP INTO A THIN STRIP
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.

4-roll, 6-roll, 18-HS-roll stand having a cassette-type design
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).
