Abstract:The SmartCrown profile and flatness control technique was first used on wide strip tandem cold rolling mills at WISCO. During operation, some problems were found, for example, the shifting stroke of the SmartCrown work rolls couldn’t be used well enough and the rolls were worn very badly and nonuniformly. Through using the ANSYS, the threedimensional finite element roll system model was built to analyze the effect of contact pressures on roll wear.On the basis of SmartCrown work roll contours used on 1700 tandem cold rolling mill, the optimized work roll contoursSmartCrown plus was developed. It was shown by that SmartCrown plus has smaller and uniformer roll wear, and is selfmaintainable, and it is used on 1700 mill at WISCO.
