How to optimize and adjust the single stand reversible cold rolling mill

Issue Time:2022/03/31
With the development of cold rolling technology, the demand for higher processing of strip steel products increased significantly, the main steel mill manufacturer is stepping up the competitiveness of the steel market, to finish rolling process, the development of high speed, automation, high precision bearings technology research is imminent, the test system development project and steel on the basis of a single support model integration, The optimization of single support reversible cold rolling mill is studied, and a practical model and high precision balance adjustment are obtained.

Current control system is the core of the cold-rolled computer system, the main task is to calculate the best control, and the operation of the rolling production application, through to the process control system module function structure analysis and design, design the level L1 and L3 data flow chart and process control system, obviously equilibrium configuration, computed from previous data ready for receiving, Data is sent through the whole L1 process, which makes the optimization study of cold mill adjustment clearer, and the timing design of modules related to production preparation.

Model in order to obtain high precision cold rolling group, will increase the elasticity theory model to calculate the mathematical model of area and thickness of the output calculation model, and show the radius is used to derive the uncoupled model of rolling force is calculated after the wafer, avoids the iterative process of cold rolling production line, a subset of the set of each model is established and the model equation of rolling analysis, Using the adaptive theory of smooth control index, the control relation of rolling model is studied, focusing on the calculation of deformation resistance and the understanding of friction coefficient.

At present, a rolling force model which adjusts the anti-deformation force and friction coefficient is established, and the data network is used to predict the rolling mill parameters and adjust the rolling force deviation compensation in an adaptive way. The simulation experiment is carried out in the actual research method, and the simulation results are analyzed in detail, which verifies the feasibility and effectiveness of the method.
