Abstract

A control apparatus of a rolling mill includes a load top/bottom distributor distributing loads as top and bottom side loads, a load top/bottom variation identification mechanism identifying load variation components occurring in connection with a rotational position of rolls from the top and bottom side loads, and top/bottom identified load variation storage storing, for each rotational position of rolls, top and bottom side variation components of the load in a kiss-roll condition identified by the load top/bottom variation identification mechanism. A manipulated variable computer computes a roll gap instruction value based on the top and bottom side variation components of the rolling load identified by the load top/bottom variation identification mechanism, and the top side variation component and the bottom side variation component of the load in a kiss-roll condition stored in the top/bottom identified load variation storage.
