った。[0003] However, in this rolling mill operating method, when an abnormal crown or shape occurs in the rolled material, the portion having an abnormal crown or shape is rolled, and the sheet exits the rolling mill and a thickness measuring device or the like is used. After reaching the plate shape measuring device, the adjustment of the roll gap shape between the upper and lower work rolls is started. For this reason, there is a problem that it takes a long time until the adjustment of the shape of the work roll gap is completed, and the rolled material that has passed through the rolling mill during this time lag has not corrected the sheet crown shape.
Further, in the conventional rolling mill, the distribution of the rolling load between the rolled material and the work roll in the width direction cannot be directly detected, and therefore, the distribution of the rolling load in the width direction cannot be adjusted with high accuracy. For this reason, rolled sheet crowns
There was a problem that it was difficult to control the shape with high accuracy.

る。In the conventional plate rolling mill, since the distribution of the rolling load between the rolled material and the work roll in the width direction of the plate, as well as the distribution of the load between the work roll and the reinforcing roll is unknown, the roll of the sheet crown after the rolling is not known. It was impossible to accurately estimate and control the shape using information obtained only from the rolling mill. In the rolling mill of FIG. 1 or FIG.
The load distribution between the reinforcing rolls is measured by a load detecting device provided for each divided reinforcing roll, and based on this information, the load distribution between the rolled material and the work roll is estimated, and thereby the sheet crown and shape after rolling are estimated. It can be estimated and controlled with high accuracy.
