【摘要】：由于工艺和结构的特殊性,带钢热轧平整机的工作辊磨损演变规律与热连轧过程有显著差别。然而,目前对工作辊磨损的研究主要集中在热轧,对热轧平整机磨损演变规律的研究较少。为此,从热轧平整机工作辊的磨损特点出发,结合现场大量实测磨损数据,分析磨损的形成与发展机理。通过ABAQUS有限元仿真分析软件建立单机架四辊热轧平整机的辊系-轧件耦合计算模型,揭示不同磨损阶段工作辊接触应力对磨损演变的作用规律。通过与某厂1 580 mm热轧平整机的实际数据对比,结果表明,工作辊磨损演变规律能够准确地反映实际生产过程的磨损情况,为热轧平整机轧辊磨损理论的发展与磨损预报模型的进一步优化奠定了基础。
[Abstract]:Due to the particularity of process and structure, the work roll wear evolution law of hot strip mill is obviously different from that of hot continuous rolling process. However, at present, the research on work roll wear is mainly focused on hot rolling, and there is little research on the wear evolution law of hot rolling mill. Therefore, based on the wear characteristics of the work roll of hot rolling and leveling mill, the formation and development mechanism of wear are analyzed in combination with a large number of field measured wear data. The coupling calculation model of roll system and workpiece of a single stand four-roll hot rolling mill was established by using ABAQUS finite element simulation analysis software, and the effect of contact stress on wear evolution of work roll in different wear stages was revealed. By comparing with the actual data of 1 580 mm hot rolling mill in a certain factory, the results show that the work roll wear evolution law can accurately reflect the actual production process of wear. It lays a foundation for the development of roll wear theory and the further optimization of wear prediction model.
