ABSTRACT:
A method to measure strip shape in rolling and a method of using the measuring method to control the same are provided in present invention, which can dramatically simplify the computation during the measurement of strip shape. On the basis of a prior mathematical model, the invention is realized by applying a strip rigidity coefficient q reflecting the features of a piece to be rolled, and a shape rigidity coefficient m reflecting those of a mill, to express heredity coefficient .eta..
