Abstract

PURPOSE: To improve the accuracy of shape control of rolled metal plate by effectively using a crown detector with high reliability.
CONSTITUTION: In the method for controlling the shape of metal plate of rolling mill which is provided with a means for controlling lateral rigidity such as a work roll bender and variable crown roll, a rolled shape is set by using the quantity of mechanical crown, the quantity of sheet crown is detected in the rear of rolling mill and the quantity of mechanical crown is corrected so that the detected quantity of sheet crown equals the quantity of mechanical crown. That is, such rolling that the crown ratios (quantity of sheet crown/thickness) on the inlet side and outlet side of rolling mill are made constant is possible and has an effect of improving the flatness of sheet. The correction of crown quantity is executed with a load controller 4 for work roll bender.
