摘要
针对热轧无取向硅钢生产过程中出现的局部高点问题,对生产流程进行深入剖析,精准识别出影响局部高点形成的关键因素,涵盖轧制工艺参数、带钢边部温降及轧辊磨损等。基于此,提出了一系列优化轧制工艺、控制边部温降、新增轧辊磨损模型、下游机架采用异步正弦窜辊策略等有效改善措施。实践结果表明,这些措施显著降低了局部高点的发生率,大幅提升了产品质量,为热轧无取向硅钢生产的质量控制提供了坚实的理论依据与宝贵的实践指导。
In viewing of the local high point problem occurred in the production process of hot-rolled non-oriented silicon steel,a thorough analysis of the production process was conducted to accurately identify the key factors affecting the formation of local high points,including rolling process parameters,edge temperature drop of strip steel,and roll wear.Based on this,a series of effective improvement measures have been proposed,including optimizing the rolling process,controlling the edge temperature drop,adding a rolling mill wear model,and adopting asynchronous sine roll shifting strategy for downstream stands.The practical results strongly indicated that these measures significantly reduced the incidence of local high points,greatly improved product quality,and provided solid theoretical basis and valuable practical guidance for quality control in hot-rolled non-oriented silicon steel production.
