PURPOSE:To improve plate crown accuracy over the whole length of a stock being rolled at a low cost by reducing a quantity of deviation from the target value of a plate crown, causing a difference between the predicted value and the actual result value of a rolling temperature, and the quantity of deviation of a plate crown, causing a difference between the predicted value and the actual result value of a plate crown on a finish inlet side. CONSTITUTION:A quantity of deviation from the target value of a plate crown, causing the deviation of the predicted value, and the actual result value of an inlet side plate crown, which are used for setting of the quantity of the crown control of a crown control mechanism, is found (steps 11 and 12) to control a plate crown at the time of the hot rolling of a stock being rolled. And a temperature distribution in the plate width direction on the inlet side of the stock being rolled, is found (step 13). The quantity of a crown control is corrected during rolling according to these quantity of deviation and the temperature distribution in the plate width direction (steps 16 and 17).
