Abstract To improve the precision of shape controlling, taking best shape as object function, a set of models were developed for optimizing backup roll contour of temper rolling mill. To optimize calculation speed, the original object function was transformed into another form, which avoided the coupling calculation between metal model and rolls model, obviously decreased calculation time and increased models’ robustness. The optimization result was used in 900 mm temper rolling mill of Ling Steel. Productive practice shows that shape control ability of the mill is apparently enhanced, and the bending force is decreased, and the effect of shape control is enhanced.
