This rolling mill for compensating the mill molds and the offset value of the roll gap, has a number of measuring means for data, including material size, roll gap, and reaction force associated with the rolls. An arithmetic processing unit, e.g. a computer, receives the data during a number of successive sampling periods to execute predetermined processing, separately calculating the most reliable values of a mill molds and offset of the roll gap to use such value as input data for controlling the rolls. The processing is provided for each pair of rolls. Pass setting controls improve rolling accuracy by calculating data during actual rolling to feed back data to a control system.
