摘要：

为了获得最优带材出口板形，在构建对辊耗程度判断指标的基础上，建立了工艺润滑制度优化模型。为验证优化方法的实际应用性能，对2160 mm热连轧机组进行了辊耗控制试验研究，深入分析了工艺润滑下辊间压力横向分布，综合运用试验轧机与理论分析，构建得到了以辊耗控制为目标的工艺润滑技术，实现了优化工艺润滑制度的效果。研究结果表明：用于评价辊耗状态的目标函数由0.415减小为0.068，板形值由最初的13.32减小至10.46，带材轧制的热滑伤指数减小了14.6%，打滑因子减小了13.2%，辊耗减小了17.4%。采用提出的优化方法对热连轧机组生产过程进行了控制测试，获得了峰值更小的辊间压力分布，实现了对轧辊辊耗的有效控制，避免了机组打滑现象，实现了经济效益的显著提升。

In order to obtain the optimal strip outlet shape, the optimization model of process lubrication system was established on the basis of the index of determining the degree of roller consumption, and the roller consumption control experiment was conducted on the 2160 mm hot tandem mill in order to verify the practical application performance of the optimization method. Then, the transverse distribution of the pressure between rollers under process lubrication was deeply analyzed, and by comprehensive application of the test mill and theoretical analysis, the process lubrication technology with roller consumption control as the objective was established to achieve the effect of optimizing the process lubrication system. The results show that the objective function for evaluating the state of roller consumption decreases from 0.415 to 0.068, the shape value decreases from 13.32 to 10.46, the thermal slip index decreases by 14.6%, the slip factor decreases by 13.2%, and the roller consumption decreases by 17.4%. The optimization method proposed is used to control and test the production process of the hot tandem rolling mill, and the pressure distribution between rollers with a smaller peak value is obtained, which can effectively control the roller consumption of roller, avoid the slipping phenomenon of the unit, and realize the significant improvement of economic benefits.
