Abstract：

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.
