<p>PROBLEM TO BE SOLVED: To constantly control a load ratio between rolling stands while keeping the balance of a mass flow between the rolling stands and alleviating a load an operator incurs.SOLUTION: If a practical load is inconsistent with an estimated load, a process computer 11 corrects the set values of a frictional coefficient of a rolling roll and a deformation resistance of a steel plate so that the difference between the practical load and estimated load can fall within a predetermined range. In addition, the process computer 11 corrects a target plate thickness of the steel plate at the exit of each of the rolling stands so that the difference between the load ratio between the rolling stands and the set value of the load ratio between the rolling stands employed in designating the target plate thickness can fall within a predetermined range. Accordingly, while a load an operator incurs is alleviated and the balance of the mass flow between the rolling stands is kept, the load ratio between the rolling stands can be constantly controlled.</p> |
