<p>PURPOSE:To eliminate an off-center of a rolled steel plate and to prevent the generation of squeezing accident by measuring a temperature difference in the plate width direction of the rolled steel plate, and talking this as a correcting data of a load deflection, performing the correction of the position of a leveling rolling reduction. CONSTITUTION:The standard temp. deflection, mean temp. deflection, etc., at the right and left end parts of the rolled steel plate S measured by a thermometer 4 for the plate width direction are transmitted to an arithmetic unit 5. In the arithmetic unit 5, based on the transmitted measured temp. data, the position correcting amount of the leveling rolling reduction required for making the off-center amount of the rolled steel plate S to be zero is calculated. The calculated correction amount of the leveling rolling reduction is divided into two, to correct the set value of the rolling reduction in the mutual opposite direction, then, this corrected value of each rolling reduction set value is transmitted to a rolling reduction control device 6 of the operating side and the rolling reduction control device 7 of the driving side respectively. Each rolling reduction control device 6, 7 performs the rolling reduction position control based on each corrected rolling reduction set value.</p> |
