<p>PROBLEM TO BE SOLVED: To obtain a sheet crown control method of a material to be rolled and shape controller for making highly responsive control and highly accurate control compatible in a continuous rolling mill. SOLUTION: A material 90 to be rolled which is conveyed is tracked with a tracking device 40, and till the tip of the material 90 to be rolled reaches a sheet crown detector 30 arranged on the outlet side of a final stand F7, roll bending devices 11-17 are controlled, based on the estimated value of the sheet crown which is calculated with an absolute load feedback controller 50. After the tip of the material 90 reaches the sheet crown detector 30, the roll bending devices 11-17 are controlled, based on the measured value of the sheet crown which is calculated with a sheet crown feedback controller 60.</p> |
