摘　　要：针对某厂1780mm热轧生产线,现场实测了精轧机组F_4机架高速钢轧辊的磨损辊型曲线,并与模型计算曲线进行了对比,上辊计算值比实测值大96.5μm,下辊计算值比实测值大78.3μm,误差较大。经过对模型参数进行优化和调整后,磨损预测值与实测值较接近,提高了轧辊磨损预报精度。Based on a 1780mm hot strip rolling line, the wear curve of work roll of F4 finishing stand was measured, and the measured value was compared with calculated one. The deviations of upper roll and bottom roll was 96.5μ m and 78.3μm. Therefore, the parameters of roll wear model was optimized, and the good effects were obtained.
