A learning control apparatus in a reversing rolling mill is disclosed. The learning control apparatus adds a learning calculation means that performs learning calculations based on actual values in the previous pass so as to be able to cope with the pass schedule composition peculiar to the reversing rolling mills. Furthermore, by storing learning calculation values of model errors that depend on materials and product dimensions in tables prepared group division by group division that can assimilate intrinsic model errors, the learning control apparatus of the present invention makes possible stable operation and improves accuracy of the product.
