摘　　要：针对某厂热轧平整机工作辊局部磨损严重及由此引起的辊系板形调控能力变得十分复杂等问题,提出适用于热轧平整机工作辊的磨损模型,基于此分析工作辊服役过程中特殊磨损形状对板形调控能力的影响规律。对工作辊和支持辊辊形进行仿真分析与理论研究,提出热轧平整机一体化辊形配置并进行工业轧制试验。研究结果表明:原有辊形配置不合理,易造成工作辊的不均匀磨损、工作辊过度挠曲和有害接触区过大等问题;新辊形配置使弯辊力调节比率由50%-70%缩小到25%-35%。Due to some problems of hot strip temper mill,for example,partial wear of wok rolls,which makes shape control very complex,the wear model for work roll to hot temper mill was proposed,and the rule of shape control affected by special wear contour during working was analysed.By theoretical simulation and calculation,a new hot tempering mill（HTM） roll contour configuration was proposed and applied on HTM.The results show that the primary roll contour configuration,which can cause partial wear of roll,excessive bending and harmful contact area,is improper,the new configuration makes the percentage of adjustive range of bending force decrease from 50%--70% to 25%--35%.
