PROBLEM TO BE SOLVED: To simultaneously estimate at low cost, deformation resistance and a friction coefficient between a rolled target material and a pressure roll, and to suppress, in rolling, dimensional defects of the rolled material from occurring and rolling efficiency from deteriorating.SOLUTION: In a rolling machine control apparatus 1 as an embodiment of the present invention, an estimation unit 6 solves an optimization problem of calculating deformation resistance k of a rolled target material S and a friction coefficient μ between the rolled target material and a pressure roll, in which an evaluation function J satisfies a predetermined condition, thereby calculates the deformation resistance k of the rolled target material S and the friction coefficient μ between the rolled target material S and the pressure roll. By this, the deformation resistance k and the friction coefficient μ between the rolled target material and the pressure roll can be simultaneously and highly accurately calculated at low cost, and occurrence of dimensional defects of the rolled material and deterioration of rolling efficiency can be suppressed during rolling. |
