Abstract
A shape control apparatus for producing rolled products from flat material comprising a plurality of rolls for shaping the material. Temperatures at a plurality of points, including a widthwise center of the material lying on an incoming side of the rolls, are detected to determine a widthwise temperature distribution. A rolling history of the number of products rolled and time interval between rolling of products, and the rolling weight are taken into consideration to determine a thermal crown magnitude and a roll wear magnitude for the rolls. An optimum bending force for controlling the rolls is determined based on calculated results of the thermal crown magnitude, the roll wear magnitude, and the load distribution of the rolls.
