Abstract：The wear contours of work rolls are observed generally and irregular uneven wear in a 2 250 mm hot strip mill cannot be precisely predicted by the models based on the pre-established pressure distribution function or uneven wear function. The concentrated uneven wear has strong heritability on the local thickening of strip cross-section contour，which is the negative factor and bad for profile control. Based on the heritability between uneven wear and local thickening，a new model is proposed and implemented. The model parameters are determined by Matlab genetic optimization toolbox. The model is validated experimentally in the plant.
