Abstract

PURPOSE:To improve accuracy of plate width by determining deviation between measured value of width at outlet side of edger stand of a hot reversing rougher and target value, and correcting the rolling reduction of edger stand at the next pass by the deviation. CONSTITUTION:A width meter 15 is installed between an edger stand 14 and a horizontal stand 16. The plate width of a rolled stock is measured and the deviation from the target value is determined. The rolling reduction at the time of next pass is corrected by the deviation. Correction of width return is also made possible by measuring the width return due to the horizontal rolling stand 16 caused by reversed pass with a width meter 15 and correcting the rolling reduction at the time of next pass similar to the above.
