Abstract
This invention relates to a method and apparatus for improving rolling mill efficiency by providing modified fixed setup parameters according to the class of the material being rolled through the following steps: (1) divide the products produced by the rolling mill into hardness/rollability classes; (2) empirically establish a set of fixed interstand thicknesses for each class which produce desired operational characteristics, such as constant thermal operation; and (3) vary the entry thickness for a particular product in accordance with the set of fixed interstand thicknesses for its class proportionally based on the desired exit thickness.
