摘要： A method and apparatus for rolling a strip by a rolling mill wherein one back-up roll of the pair of back-up rolls is a variable crown roll having a single oil chamber and the other back-up roll is a variable crown roll having a plurality of oil chambers. The strip shape is detected by a shape meter and approximated by a power function which includes terms of the first, second, fourth, and sixth powers of a distance measured from the center in the width direction and then precisely controlled by a calculation and control unit based on the obtained power function.

摘要： A rolling mill having an upper set of rolls which has a work roll and a backup roll, and a lower set of rolls which has a work roll and a backup roll. Two parallel intermediate rolls are arranged between the work roll and the backup roll of either upper set or lower set or both sets, each of the intermediate rolls being supported by corresponding support rolls. The support rolls can be shifted toward and away from the corresponding intermediate rolls.

摘要： Each of a pair of rolls has a barrel with different diameters axially of the barrel such that sum of the diameters of the barrels is substantially constant and that each of the rolls is bilaterally symmetrical. The rolls themselves have an ability to control workpiece profile and have at least one substantially parallel center portion.

摘要： Controlling for obtaining the aimed strip shape using a rolling mill provided with rolls, which are variable in amount of crown by feeding a pressurized oil in the inside. In addition, the rolling mill is provided with right and left pressing-down balancers and roll benders. The strip shape in the width direction of the strip is detected, the detected shape being approximated by a function including terms of the first, second, fourth, sixth or eighth power of a variable, which is a position or a distance in the width direction of the strip, the amount of pressing-down of the right and left pressing-down balancers being adjusted to coincide the term of the first power with the aimed value thereof, the amount of crown of the roll being adjusted to coincide the term of the second power with the aimed value thereof, and a roll bending force being adjusted to coincide the term of the fourth, sixth or eighth power with the aimed value thereof.

摘要： A rolling mill arrangement having at least one roll carrying a sleeve forming a cavity with the roll body near the two opposed ends of the roll. Pressurized fluid is regulated in these cavities to counteract "edge drop" which occurs at the edges of a product under the conventional procedures for controlling the mill for effecting control of the edge thickness of the strip when reducing the product along its width.

摘要： In a sheet rolling mill having work rolls and backup rolls, rolling of flat sheets is facilitated by controlling constant the transverse rigidity or deflection in the direction of width of rolls. The rolling force is detected, and based on the rolling force thus detected, the value for correcting the crown of the work roll is calculated by a transverse rigidity coefficient and a function determined by sheet thickness to control the transverse rigidity.
