PURPOSE:To precisely control the plate crown after finishing finish continuous rolling into an objectives crown without receiving the influence of changes of the plate crown at the inlet side of a finish continuous rolling mills. CONSTITUTION:The plate crown of a material to be rolled is actually measured at plural places of the longitudinal direction of the material to be rolled between a rough rolling mill 9 and a finish continuous rolling mills M, and the controlling amount of the rough mill is corrected by feeding back the deviation of this crown actual measured value and the objective crown of the material to be rolled at the outlet side of the rough rolling mill 9 against the rough rolling mill. The plate crown actual measured value is set as initial value by feeding forward the crown actual measured value to the finish continuous rolling mills M, calculating the objective crown of each stand of the mills M about each measuring place, deciding the controlling amount of the crown controlling equipment of each stand which for achieving this objective crown, and deciding the controlling amount of the crown controlling equipment with matching to the movement of each measured place of the material to be rolled inside the mills.
