摘要： Regarding each rolling mill, a rolling torque Gi before biting into a downstream stand is stored, the peripheral velocity of a most downstream stand Rn is controlled to be Gn−1=Gn−1* after biting into Rn, and a rolling torque Gn** of Rn after tension is stabilized is stored. After that, the peripheral velocity of a rolling mill Ri is controlled to be Gi=Gi* toward an upstream side, and the peripheral velocity of a rolling mill Rk at a downstream side of the rolling mill Ri is controlled to keep Gk=Gk** (k=i+1 to n) so that a rolling torque of a most upstream rolling mill R1 becomes equal to a stored G1*. Stabilization of material passage and improvement in accuracy of a product dimension are enabled by controlling tension between stands with high accuracy by using a simple control system without using table values or the like by each rolling condition even under a condition where a distance between stands is short.

摘要： Described herein is a method for rolling metal sheets of variable thickness. The method makes it possible to impress, during rolling, any distribution of areas of increased thickness within a figure corresponding to the plane development of a motor-vehicle component prior to the pressing operation. Impression of the desired distribution of areas of increased thickness envisages simultaneous impression, during rolling, of a further distribution of areas of increased thickness, or compensation areas.

摘要： A rolling plant for rolling all types of finished sections from flat blooms or preliminary sections with close to final dimensions, wherein the blooms or preliminary sections arrive from a continuous casting plant and may be stored in reheating furnaces arranged in front of the plant and/or may be maintained at rolling temperature. The rolling plant includes a compact rolling group with two universal stands arranged closely one behind the other and an edging stand arranged between the universal stands. A roughing group is arranged in front of and parallel offset to the compact rolling group, wherein the roughing group is composed of a group of a vertical stand, a horizontal stand and a universal stand arranged closely one behind the other. A roller table each is arranged in front of and following the compact rolling group, wherein the length of each roller table corresponds to the exit length of the finish-rolled stock; arranged following the roughing group is another roller table which extends parallel to the two roller tables over the length of both of these roller tables and past the compact rolling group, wherein transverse conveying units are arranged between the parallel roller tables.

摘要： An adjusting mechanism for a universal stand, particularly for a finishing stand in a group of compact roll stands and a method for operating the adjusting mechanism. The adjusting mechanism includes two hydraulic control cylinders for at least one horizontal roll which is usually the top roll. The at least one horizontal roll and the two vertical rolls are provided with hydraulic fine adjustments and each roll having a hydraulic fine adjustment is provided with an electromechanic coarse adjustment which can be operated independently of the fine adjustment. The electromechanic coarse adjustments as well as the hydraulic fine adjustments are monitored with respect to position of displacement pickups. The fine adjustments are additionally monitored by means of pressure pickups or rolling force pickups. The hydraulic fine adjustments are set up for the adjustment and opening of the rolls under pressure. All actual values measured with respect to position, pressure and/or rolling force can be stored and reproduced in an electronic control device. The hydraulic fine adjustments are controlled in accordance with displacement.

摘要： Sheet steel profiles are rolled in a rolling line including a number of rolling mills. The starting material is first reduced and shaped conventionally in successive mills, and then the final rolling takes place initially by preliminary bending of the sheet steel profiles to the starting (first pass) shape. At this stage, the interlocking joint portion of the profiles are given a shape suitable for the finished profile. The finishing pass is then performed to give the profile cross-section its finished dimensions. All these final rolling operations take place continuously and in one direction.

摘要： A cartridge loadable combination mill for rolling beam, structural or plate products. The combination mill includes a pair of cartridge or cartridge-like loaded mill stands, the first of which has a movable mill housing and the second of which is adaptable to being moved out of the mill line. The cartridges contain a pair of horizontal and vertical rolls that are aligned and adjusted prior to insertion into the mill stands through the mill housing windows. A four station cartridge transfer means having alternative stations simultaneously alignable with both mill stand windows is provided for supporting, positioning, and transferring work roll cartridges to the mill stands for insertion therein. A pair of movable table rolls with side guards adjustable to the maximum width of the first mill stand are movable either along the mill line or out of said line.
