摘要： A method of controlling roll eccentricity of a rolling mill is disclosed, in which a component of a rolling load variation which is due to eccentricities of an upper and a lower backup rolls of the rolling mill is obtained as a first eccentricity compensation signal by removing a rolling load variation component due to a variation of thickness of a material to be rolled from a rolling load variation occurred during the rolling operation, a rolling load variation value due to the roll eccentricity of the backup rolls is obtained from a rolling load variation occurred during rotations of work rolls which are in contact with each other under a load and is memorized as a second roll eccentricity compensation signal, a first signal is obtained by multiplying the first roll eccentricity compensation signal with a coefficient which is larger than 0 and smaller than 1, a second signal is obtained by multiplying the second roll eccentricity compensation signal with another coefficient which is larger than 0 and smaller than 1, and the first and second signals are added to obtain a roll eccentricity compensation signal for the rolling mill. An apparatus for performing the same method is also disclosed.
