摘　　要：以国内某1700热连轧机为对象,研究了轧辊磨损模型,分析了影响轧辊磨损的各种因素.编制离线仿真程序,计算某一轧制周期工作辊磨损.结果表明工作辊磨损形状近似箱形,受带钢宽度影响较大,带钢长度是影响磨损量的一个重要因素,一个轧制周期后,F7工作辊中心磨损约为302μm.将程序计算得到的轧辊磨损曲线与采用高精度磨床测量得到的实际磨损曲线比较,两者吻合较好,表明此轧辊磨损计算模型具有较高的计算精度.The roll wear model for 1700 hot strip milI（HSM） was studied and the influencing factors on roll wear were analyzed. Programming the off-line simulation process and computing the working roll wear in a certain rolling period as scheduled. The results showed that the roll wear presents a box-like shape and is affected mainly by strip width. The strip length is also one of the important factors affecting roll wear. The wear on the middle of the top roll F7 is about 302μm after a rolling period. The roll wear curve obtained by programmed computation is compared with that plotted according to the actual measurement on a high-precision grinder, and both are well in conformity. The model is therefore proved highly accurate.
