Therefore, it is very important to study the power problem of tandem cold rolling of the previous configuration data mill, so as to maintain the normal production plant, realize complete continuous rolling and improve product quality and product performance. Through the analysis of the scheme of dynamic variables in the existing technical specifications, the problem of configuration data rolling is mainly solved, Two methods for improving the predetermined accuracy are proposed, and good results are obtained.
Firstly, the problem of dynamic specification of tandem cold rolling mill is briefly described, and the basic problems and objectives to be studied are clarified. Considering the two most important parameters affecting data rolling, deformation resistance and friction coefficient, the mode based on adaptive optimization method is set to improve the preset accuracy of data rolling. This method uses the measured data to replace the corresponding mathematical model to solve the subsequent calculation of the model of these two parameters, And calculate the actual parameter value.
Then, the adaptive learning pattern of deformation resistance and friction coefficient is set so that these two parameters have been optimized. In turn, the predetermined accuracy of rolling data is improved. In addition, a method of constructing data network and combining it with mathematical model is proposed to improve the pre established accuracy of rolling data. This method provides the approximate value of continuous data according to the traditional mathematical model.
Finally, comparing the simulation results of rolling mill, the prediction accuracy of the comprehensive network method is better than the traditional model calculation method and the calculation method of adaptive optimization model. This method has a wide application prospect. In order to verify the shape control effect of strip control system on several thickness gauge strips, the shape control effects of traditional gauge strips and ultra-fine gauge strips are tested respectively, and the process of formal control is analyzed, The dynamic response characteristics of each shape adjustment mechanism are analyzed.
