Claims

[Scope of utility model registration request]

In a multi-high rolling mill, the pass line height changes due to changes in roll diameter when changing rolls, so a multi-stage rocker sheet of different thickness provided between the reinforcing roll bearing box in the roll housing and the roll housing is moved. In the method of changing the thickness of the rocker sheet and adjusting the pass line height within a certain range, by inputting the roll diameter under which the pass line height is changed, the locker sheet is automatically adjusted. An automatic pass line height setting device for a multi-high rolling mill, characterized in that the sheet thickness, moving distance, and the pass line height are calculated to automatically control the rocker sheet moving device to a predetermined setting position.
