| 摘 要： | 针对无取向硅钢连续自由编排"批量同宽"的自由规程轧制要求,自主开发了ASR-C非对称自补偿工作辊技术.采用ANSYS建立了三维辊系有限元模型.有限元分析和工业应用试验发现,ASR-C工作辊无论是在带钢宽度变化时,还是在轧制单位完整服役期内,均具有稳定的凸度和磨损控制双重能力,同时ASR-C工作辊增强了辊缝横向刚度和弯辊力的调节效率.在武钢1 700 mm热连轧机进行了2.55 mm×1 280 mm宽幅无取向硅钢"批量同宽"轧制的ASR-C工作辊工业试验.结果表明,凸度≤45μm的带钢比例由常规工作辊的41.8%提高到98.2%,凸度>53μm的带钢比例从33.9%下降到1.8%,ASR-C工作辊辊形自保持性达到88%.ASR-C技术取得显著稳定的凸度和磨损控制效果,实现了"批量同宽"的自由规程轧制.

| Abstract: | In order to meet the requirement of schedule-free rolling for wide non-oriented electrical steel strip production with a large number of the same width strip rolling campaigns,an asymmetry self-compensating work rolls(ASR-C) technology was developed.A three-dimensional finite element analysis model of roll stacks was built by ANSYS software package.The finite element analysis and industrial tests indicate that the developed ASR-C technology has both crown control ability and wear control ability for differe... |
