    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.

    摘要： A multiple-part machine frame with a substantially rectangular opening and intended particularly for presses or rolling mills as a pair of longitudinal frame members which are interconnected by transverse frame members through which pass first tie-rods for securing the longitudinal and transverse members. Co-operating force transmitting surfaces are provided on the transverse and longitudinal frame members for transmitting the working force from the transverse frame members to the longitudinal frame members thereby placing the latter under tension. At each corner of the frame are arranged pre-stressed second tie-rods extending through the force transmitting surfaces to interconnect the transverse and longitudinal frame members thus preventing separation of these surfaces when a relieving force acts in a direction opposite to the working force.

    摘要： A rolling mill, in particular a cold rolling mill, including: rolls or even sets of rollers comprising at least one pair of work rolls capable of defining a roll gap of a strip to be rolled, at least one bar for spraying a lubricating and/or cooling fluid, disposed near the plane of the strip to be rolled, a stand inside of which the rolls are arranged, at least one device for adjusting the inclination of the at least one bar comprising an actuator, such as a hydraulic cylinder configured to change the inclination of the bar around the pivot axis. The actuator of the device for adjusting the inclination is arranged, on the second side of the stand, opposite to the first side of the maintenance window.

    摘要： A roll stand for rolling mills utilizes roll frames having frame caps held down by means of pre-stressed tie rods. In one construction four tie rods in all are used and receive at their upper ends a stationary top plate seating against pre-stressing units at the upper ends of the tie rods. The top plate bears against screw-threaded sleeves seating against column embers of the frame. A support frame for the frame caps seats against ring nuts rotatable in screw-threaded sleeves for screwdown adjustment, and hydraulic cylinder piston units are provided between the top plate and the frame cap support frame to maintain pressure between the ring nuts and the sleeves or to release said pressure during screwdown which is effected by rotating the ring nuts from a common drive.
