摘　　要：对热轧CSP产线生产的硅钢板带断面进行测量发现,在工作辊服役后期生产的产品,其断面常出现局部高点现象。服役后下机工作辊轮廓也在对应带钢断面局部高点位置,呈现“猫耳”型磨损。对F7工作辊辊形进行了优化,并考虑机组设备现有的工作辊窜辊功能,使用变行程、步长的智能窜辊策略,通过改善工作辊磨损状态,均匀轧辊磨损,延长轧制公里数,改善硅钢板带断面的局部高点。该优化方案自上线以来,有效保证整个工作辊服役周期内具有良好的凸度控制能力,断面质量控制稳定性与轧制公里数大幅度提升。Measurements of the cross-sections of silicon steel strips produced on the hotrolled CSP line revealed that the cross-sections of products produced in the later stages of work roll service often showed localized high spots.The work roll profile also showed "cat’s ear" type wear at the local high point position of the corresponding strip section after service.The roll shape of F7 work roll was optimized, and the existing work roll shifting function of the unit equipment was considered, an intelligent shifting strategy with variable stroke and step length is used to improve the local high point of the silicon steel strip section by improving the wear state of the work roll, evening out the roll wear, and extending the rolling kilometers.The optimization plan effectively ensured good convexity control capability throughout the service life of the work rolls, and improved the stability of section quality control and rolling kilometers.
