热轧带钢平整机工作辊磨损规律

 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。

Work roll wear law for hot strip temper mill

Because of special characteristics of process and structure of hot strip temper mill,the work roll wear evolu-tion law is different from that of hot strip mill. However,researches on work roll wear mainly focused on hot strip mill and there was little research on work roll wear evolution law of hot strip temper mill. Accordingly,On the basis of the wear characteristics of hot strip temper mill,a large number of wear data were measured for analyzing the formation and development mechanism of work roll wear. For single-stand four-high hot temper mill,a roll-strip coupling model was established with ABAQUS finite element simulation software and effect of contact pressure on work roll wear evolution rule in different wear stages was obtained. Compared with the actual data of 1580 mm hot strip mill,the results show that work roll wear evolution law can accurately reflect real wear condition. The conclusion lays the foundation for the development of the wear theory of hot strip temper mill and the further optimization of the wear prediction model.
