摘　　要：为了降低轧辊磨损消耗和提高节能效果,建立了低温微量润滑优化工艺,并在由七个机架组成的2160 mm热连轧机上开展轧辊消耗试验。通过现场测试分析了工艺润滑下辊间压力横向分布,并开展低温微量润滑优化前后指标参数对比。研究结果表明:相比较润滑优化前,增加低温微量润滑工艺后,热滑伤指数减小了约15%;打滑因子减小了约13%;轧辊消耗减小了约18%。采用本文的低温微量润滑优化方法有效减小轧辊消耗,进而有效避免打滑现象,最终优化了带钢出口板形,实现了节能效果和热轧质量的大幅提升。In order to reduce roll wear consumption and improve energy saving,a low temperature micro-lubrication optimization process was established,and roll consumption tests were carried out on 2160 mm hot tandem rolling with seven stands.The transverse distribution of pressure between rolls under process lubrication was analyzed by field test,and the index parameters before and after low temperature micro-lubrication optimization were compared.The results show that the thermal slip index is reduced by about 15%after adding low temperature micro-lubrication technology compared with before lubrication optimization.The slip factor is reduced by about 13%.Roll consumption is reduced by about 18%.The low temperature micro-lubrication optimization method in this paper effectively reduces the roll consumption,and then effectively avoids the skid phenomenon,and finally optimizes the strip outlet shape,realizing the energy saving effect and greatly improving the quality of hot rolling.
