ABSTRACT:
A working roll shift type rolling mill has a housing including upper and lower working rolls having working roll chocks, and upper and lower reinforcing rolls having reinforcing roll chocks. Hydraulic rams mounted between the upper and lower working roll chocks apply a vertical force to the vertically facing portions of the respective chocks. The working roll chocks are immovably mounted on their respective working rolls so that they can be moved together. Each of the hydraulic rams has one end mounted in one of the upper or lower working roll chocks and the other end engaging the horizontal wall surfaces of the upper and lower working roll chocks that are vertically adjacent to each other. The working roll chocks and reinforcing roll chocks have flat side surfaces. The housing of the rolling mill includes windows each having a flat side wall such that the working roll chocks and the reinforcing roll chocks may be lifted and lowered within the housing.
