The invention contemplates a prestressed rolling mill incorporating a system of hydraulically operated load-transfer blocks 40, wherein the blocks are of unitary construction and interposed between upper and lower back-up roll chocks, at the respective inlet and exit sides of the mill. Each load-transfer block includes its own hydraulic-control system with minimum-displacement actuators whereby a fast time constant of hydraulic response is achieved. Control of all load-transfer blocks is monitored and co- ordinated 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. <IMAGE> |
