Abstract
PURPOSE: To improve an accuracy in an estimation of a length of a material after rolled by a method wherein a ratio between an actually measured value and an estimated value in regard to the length of the material after rolled is utilized as an operation data for the length of the material in a next rolling.
CONSTITUTION: A material rolled by a standard stand 1 and a last stand 2 is sent through material detecting devices 7, 8 and cut by a cutting machine. A determination of the cutting position is effected by operating a length of the material after passing through the last stand 2 by data obtained from the last stand 2 and the standard stand 1. A relation between an actually measured and an estimated values is substantially constant in regard to the length of the material after rolled, therefore, a ratio between the actually measured value and the estimated value is obtained as a correcting factor and this factor is utilized as a part of operating data for the length of the material in a next rolling, thereby, an accuracy in the estimation of the length of the material may be improved.
