Abstract
The disclosure relates to a window layout and a work roll chock design of a four-high rolling mill stand, including two spaced upright housing posts having windows, in which the housing ports have roll bending devices for the work rolls and the chocks of the work rolls are mounted so as to be horizontally and vertically disposed relative to inner window chock support members, which in turn are connected to outer window blocks affixed to the housings. To effect a roll change of both work rolls as a unit with a roll change device arranged in front of the operator side window, the work roll chocks are provided with roll separator units for holding the rolls apart and stabilizing the unit and a locking device for preventing relative horizontal movement of the work rolls during a roll change.
