More Information
Summary:An edge drop control device calculates a first calculated manipulated amount of a work roll shift device for bringing a difference between a measured edge drop amount and a target amount close to zero without using a work roll bender device. The edge drop control device calculates a second calculated manipulated amount of the work roll bender device for bringing a difference between a measured edge drop amount and the target amount close to zero without using a work roll shift device. The edge drop control device outputs, when the first calculated manipulated amount is out of an allowable range, the second calculated manipulated amount to the work roll bender device and also outputs a difference between an amount that corresponds to the second calculated manipulated amount and the first calculated manipulated amount, to the work roll shift device.
