摘要： An improved shapemeter is provided to measure the flatness of metal strip under tension as the strip passes over a shapemeter roll, the shapemeter including a stationary shaft with a set of bearings that allow the strip to easily pass over the shapemeter roll. The stationary shaft does not touch the inner ring of each bearing, but the inner ring is urged against a block having horizontal and vertical flexural members that deflect giving only a single degree of freedom. This single degree of freedom allows each block to rotate about a pivot point, which is defined by the locations of the flexural members, in the transverse vertical plane only. The shaft has a slot, which provides an open area in which a single box that contains all the force transducers is mounted. Each force transducer (e.g., a load cell) is attached to a thrust button that contacts the corresponding block, and thereby absorbs some of the vertical load on the block. The horizontal component of the force on the block is entirely supported by the pivot flexural members. The vertical component of this force is partly supported by the pivot flexural members and partly by the corresponding force transducer (through the thrust button). In this manner, the range of force being detected by each force transducer is reduced, thereby allowing for greater low-end sensitivity and accuracy, and the variation in force sensed by the force transducer is minimized if the wrap angle of the strip varies.
摘要翻译： 提供了一种改进的形状计，用于在条带通过定形辊时在张力下测量金属带的平整度，该形状计包括具有一组轴承的固定轴，允许带容易地越过定型计卷。 固定轴不接触每个轴承的内圈，但是内圈被推靠在具有水平和垂直弯曲构件的块上，该弯曲构件仅偏转一个单一的自由度。 这种单一自由度允许每个块围绕仅在横向垂直平面中的由弯曲构件的位置限定的枢转点旋转。 轴具有槽，其提供开放区域，其中安装有包含所有力传感器的单个箱体。 每个力传感器（例如，称重传感器）附接到与相应块接触的推力按钮，从而吸收块上的一些垂直载荷。 块上的力的水平分量完全由枢轴弯曲构件支撑。 该力的垂直分量由枢轴弯曲构件部分支撑，部分由相应的力传感器（通过推力按钮）支撑。 以这种方式，减小了由每个力传感器检测的力的范围，从而允许更大的低端灵敏度和精度，并且如果条的包角变化，则力传感器感测的力的变化被最小化。

摘要： A two-part housing assembly for a cluster mill. The housing assembly has substantially the same size, form and structure as a monobloc housing, but is divided along a horizontal plane located at or close to its horizontal center line into upper and lower mill housings each provided with a roll cavity and a roll cluster therein. The gap between the work rolls of the roll clusters is adjusted by symmetrical equal and opposite movement of the upper and lower mill housings achieved by four identical screws, one located in each corner of the mill housing assembly. Each screw has two threaded portions of opposite hand, one threaded portion engaging a threaded nut of opposite hand non-rotatively mounted in a recess in the upper mill housing and the other threaded screw portion engaging a threaded nut of appropriate hand non-rotatively mounted in a recess in the lower mill housing. Each screw supports the upper and lower mill housings. A jack for each screw is provided in the mill base to support and rotate that screw. The upper and lower mill housings are adjustably prestressed together, at a spacing determined by the screws, by a pair of tie rods affixed to the piston of a hydraulic cylinder located at each corner of the mill housing assembly.

摘要： An improved device for wiping liquids from the surface by moving metal strip under tension, such as strip produced by cold rolling mills, is disclosed. The device consists of three rollers, between which the strip passes, where each roller is supported by a plurality of pairs of casters, the caster pairs being spring mounted in a pair of frames, the frames being urged together by fluid powered cylinders, so that the rollers are held against the strip surfaces under pressure, thus wiping the strip surface by preventing passage of liquid on the strip surface past the rollers.

摘要： A cluster mill housing applicable to 20-high and 12-high cluster mills. The mill housing is similar in size and form to a comparable monobloc housing but is made of four distinct parts. The first part is a floor portion having a central lower roll cavity containing part terminating in end members and having a vertical column at each of its four corners. The second part comprises a roof portion having a central upper roll cavity containing part terminating at each of its ends in ears. The third and fourth parts comprise substantially identical bridge members overlying the roof portion ears and having downturned ends affixed to the tops of the columns. Each of the bridge members contain adjustment screws which bear against the adjacent roof portion ear. A synchronized drive assembly rotates the four adjustment screws equally and in the same direction to adjust the vertical position of the roof portion with respect to the floor portion. Hydraulic counterbalance assemblies are affixed to the bridge members and are connected to the roof portion to support the weight of the roof portion and to maintain the roof portion against the four adjustment screws.

摘要： A crown adjustment system for a 20-high (1-2-3-4) cluster mill of the type having upper and lower clusters each comprising a work roll, two first intermediate rolls, three second intermediate rolls, and four backing bearing assemblies. Each of the backing bearing assemblies of the upper cluster comprises a shaft supported along its length by saddles. Each of the saddles has a projecting ring through which the shaft passes. A plurality of bearing roll segments are journaled on the shaft between its respective saddle rings. A plurality of eccentrics are keyed to the shaft, each being located within one of the saddle rings supporting the shaft. Within the saddle ring of each saddle supporting the shaft there is an eccentric ring mounted on bearing rollers between its respective saddle ring and the adjacent keyed eccentric. The saddles of each of the shafts of the backing bearing assemblies of the upper cluster are equal in number and occupy the same saddle locations so that the saddles at corresponding saddle locations on adjacent shafts lie opposite each other. Those eccentric rings on the shafts of all four backing bearing assemblies of the upper cluster, which occupy the same saddle location, are interconnected by gears and are rotatable by a drive assembly at that saddle location. As a result, a single drive means for each saddle location can be used to effect the crown adjustment on all four backing bearing assemblies of the upper cluster.

摘要： There is provided a mill computer control system for automatically controlling the position of the individual drives in accordance with at least one predetermined equation so as to produce variable profile forms of the roll gap. Crown forms and tapered forms are generated by the computer in response to single keystroke commands on the keyboard. The drives may be adjusted simultaneously or individually. Individual adjustments may be made which are preserved during changes in the crown form or the tapered form.
