High accuracy online strip profile prediction model has been developed for realize mixed scheduled rolling of high tensile strength and mild steel in hot strip finishing mill. New method is based on matrix model. The force and tension distribution is considered by experiment and FEM analysis. First the force and tension distribution when there is no change in strip profile is calculated as the specified value, second the distribution when there is an actual change in strip profile is calculated as the variation from the specified value. Then the profile prediction accuracy of high tensile strength steel, whose rolling force is higher than that of mild steel, was improved. The model was applied to online crown, flatness, and walking control in hot strip finishing mill. As the result, mixed scheduled rolling of high tensile strength and mild steel was commercially promoted.
