The roll gap in a 4-high mill is determined either by lands 21 (Fig. 1) at the ends of the work rolls 12, 13 or by rollers 36 (Fig. 7) acting on the suitably profiled ends of the rolls. The rollers are horizontally movable within yokes in the housings, and are driven by the work rolls. A prestressing force P is applied to the bearings of the backing rolls 15, 16 to control the pressure between the contacting lands 21 or the profiled roll ends to thereby control the roll gap. A bending moment may be applied to the journals of the rolls 15, 16 to counteract bending of the work rolls under load. Gauge control of a strip 14 may be enhanced by the additional use of a screwdown controlled in response to measured strip thickness, or by controlling the strip tension. The end portions of the backing rolls may be supported in 180 degrees hydrodynamic or hydrostatic bearings. (For Figures see next page.)

ПРОКАТНАЯ КЛЕТЬ И СПОСОБ РЕГУЛИРОВАНИЯ ПРОКАТНОЙ КЛЕТИ

Изобретение относится к обработке металлов давлением, а именно к прокатной клети. Прокатная клеть состоит из четырех колонн станины, неподвижно соединенных с опорной плитой. В колоннах станины расположены без возможности сдвига в осевом направлении, но с возможностью вращения ходовые валы. Верхние и нижние концы ходовых валов снабжены противоходными резьбами. На ходовых валах размещены верхняя и нижняя траверсы. С помощью ходовых валов можно регулировать с противоходом относительно друг друга комплекты валков. Колонны станины одновременно служат в качестве направляющих для подушек валков и для размещения гибочных блоков. Между нижней подушкой опорного валка и нижней траверсой расположен исполнительный цилиндр короткого хода для создания усилия прокатки. За счет раздельного расположения ходовых валов и подушек валков в колоннах станины достигается разделение передачи усилия на валки и центрирование подушек валков, что снижает склонность к проявлению периодической продольной разнотолщинности полос. 2 н. и 3 з.п. ф-лы, 1 ил.

Load-transfer mechanism

LOAD-TRANSFER MECHANISM ABSTRACT OF THE DISCLOSURE 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 con-tribution 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.

Roll position control in cluster mills

A dynamic position control means for a cluster mill which has a two-part pre-stressed housing in which the two parts are joined by hydraulic cylinders and associated columns. It comprises an actuating means located between the housings of the mill, so as to vary the relative separation or the relative orientation or both of the two halves of the housing during rolling. The actuating means includes at least one hydraulic lifting ram disposed substantially between the two halves of the housing, and ideally four hydraulic lifting rams each ram disposed at the corner position of a rectangular housing. The hydraulic lifting rams are of the doughnut type, encompassing each of the hydraulic cylinder's columns. The dynamic position control means includes position monitoring means, in particular, four position transducers mounted between the four respective corners of the housings. Control means then adjust the actuating means in response to the position monitoring means or other measured data. <IMAGE>
