摘　　要：热轧钢板成形过程中,工作辊磨损是影响板形控制精度的重要因素。分析了影响工作辊磨损的主要因素。基于对影响轧辊磨损的主要因素的分析,考虑了轧辊表面温度对工作辊磨损的影响,构建了新的工作辊磨损数学模型。根据实测数据,使用多元非线性回归方法得到了模型中的相关参数,并在1500 mm热连轧机组上进行了工程试验。结果表明,所构建的工作辊数学模型符合工作辊磨损的一般规律,能够较为精确地在线预报轧辊磨损。Work roll wear is an important factor affecting the accuracy of plate shape control in the process of hot rolled steel plate forming. Based on the analysis of the main factors affecting roll wear, considering the influence of roll temperature on the wear, a new mathematical model of work roll wear was designed. According to the measured data, related parameters of the model were gotten by using the method of multivariate nonlinear regression. And engineering experiment was carried out in 1500ram hot tandem rolling mill. The results show that the mathematical model of work roll accords with the general law of work roll wear, which can more accurately forecast roll wear online.
