摘要： An eccentric roller control apparatus is intended to eliminate the adverse effect of the eccentric upper and lower back-up rollers against a product profile with high precision. The rolling weight sensors 7W, 7D sense each rolling weight of a working side and a driving side. The rotary angles of the upper back-up roller 4T and lower back-up roller 4B are sensed by the angle sensors 8T, 8B. The roller eccentricity sensor 14 serves to derive each of the amplitudes A.sub.TWn, B.sub.TWn, A.sub.BWn, B.sub.BWn, A.sub.TDn, B.sub.TDn, A.sub.BDn and B.sub.BDn as each roller eccentricity of the working side and the driving side, based on the sensed rolling weights P.sub.W, P.sub.D and the rotary angles .THETA..sub.T and .THETA..sub.B. Then, the depression operating unit 15W serves to derive the depression of the working side and add the derived value to the depressor control device 6W. The depression operating unit 15D serves to derive the depression of the driving side and add the derived value to the depressor control device 6D.

摘要： A rolling mill has a work roll and a back-up roll for supporting the work roll vertically and driving it. A plurality of horizontal support rollers contact the work roll at barrel diameter outside the rolling region and at a both horizontal sides of the work roll and act to fix the position of the work roll in both horizontal directions during rolling and to oppose horizontal rolling forces. In order to reduce the bending of the work roll during rolling, there are provided means for applying horizontal counterbending forces to the work roll comprising members e.g. rollers, contacting the work roll at locations axially further from the rolling region than the support rollers and actuator means for urging the members against the work roll. The counterbending forces being in the same direction as the net horizontal force applied to said work roll by said back-up roll and the material being rolled. Preferably at least one condition of said work roll is sensed during rolling, and there are control means acting during rolling to control the counterbending forces in dependence on the sensed condition.

摘要： A hot or cold leveler is provided having conventional high loaded driven work rolls backed up longitudinally across their face by a plurality of short backing rolls. A series of lower work and backing rolls are cassette mounted on the lower main frame of the leveler. The upper backing rolls are mounted on an intermediate support frame designed for limited flexure and which in turn is supported across its length by a plurality of hydraulic piston-cylinder assemblies fixed in the top main frame of the leveler for contouring of the leveling action. Each cylinder is controlled by a servo valve which can be operator-adjusted to work the sheet material across its width dependent on sheet flatness. Buckling at the center, quarter, or edges of the sheet can be removed by a corrective positioning of the piston-cylinder in the location of the buckle. Entry and delivery rollers are similarly servo-controlled. The entry roll is backed off to permit the sheet product to enter the machine and it acts as an anvil roll. The delivery roll is adjusted to deliver flat product onto a delivery table. Pressure transducer means and piston position transducer means are provided in each cylinder, whereby a positive feedback signal is provided due to loads on the flexible beam exerted by the material being worked to withdraw or inject hydraulic fluid to the cylinders.

摘要： The calender comprises a predetermined number of rolls and at least one of the rolls, for example, the outer roll or the lowest roll of such predetermined number of rolls is structured as a tubular roll or controlled deflection roll comprising a stationary roll support member or beam and a roll shell which rotates about the stationary roll support member and is supported thereat. A position sensor determines the position of the roll shell which is regulated with respect to predetermined reference values by a regulating device. A pre-selected number of different reference values for the position of the roll shell are provided and by selecting an appropriate one of these reference values there is achieved the result that different numbers of the predetermined number of rolls are operative while the remaining rolls of such predetermined number of rolls bear against related stops so that their related roll nips or gaps remain open.

摘要： The invention contemplates a prestressed rolling mill incorporating a system of hydraulically operated load-transfer blocks, wherein the blocks are of unitary construction and bodily interposed between vertically opposed regions of upper and lower back-up roll chocks, at the respective inlet and exit sides of each axial end of the mill. Each load-transfer block is inherently self-adapting (at each of a plurality of force-application regions) to such small locally different deformations in the mill frame as result from the block's modulating contribution to net prestressing force; further, each load-transfer block includes its own hydraulic-control system with minimum-displacement actuators whereby a fast time constant of hydraulic response is achieved. Still further, control of all load-transfer blocks is monitored and coordinated through a microprocessor having instantaneous hydraulic-pressure and positional data inputs electrically supplied from all load-transfer blocks, as well as from various other data inputs pertaining to mill operation.
