摘　　要：某冷连轧机生产无取向硅钢板材时,其边缘降的长度合格率频繁超标。为满足用户的叠片厚度精度要求,这类产品必须以增大切边量的方式来保证交货质量,而这种方式又直接降低了金属收得率,提高了生产成本。基于此,以该产线现有设备特性为基础,详细分析其软、硬件功能模式,分别对辊形与反馈控制进行全面分析与优化改进。通过现场试验论证,充分明确依托辊形优化与反馈控制程序的改进能显著提高边缘降的控制水平,该技术的使用为生产现场的边缘降控制提供了合理的技术支撑。A cold rolling mill production of non-oriented silicon steel sheet, the thickness difference of the edge （edge-drop） is usually exceed the preset standard value, In order to meet the accuracy requirements of the user flatness, these production must be trimed wider length to meet the delivery quality of the user need, which directly reduce the metal yield and increase the manufacturing cost. Therefor, the software and hardware of the production line has been analyzed, and the work roll shape and feedback control has been improved and optimized in this paper. Through the theoretical analysis and actual test, the roller optimization improvements and optimization of the feedback control improvements can significantly improve edge-drop. The using of this technology provides a resonable technical support for the production line.
