Dynamic distribution and automatic control system for cold-rolling hydrochloric acid pickling line outlet ductility

The invention relates to a dynamic distribution and automatic control system for cold-rolling hydrochloric acid pickling line outlet ductility. A primary basic automation system dynamically distributes the ductility control mode in real time according to a production plan; ductility setting values are dynamically distributed to a withdrawal and straightening machine and a finishing machine through different corrected parameters according to the situation in an actual application site and the actual production of various strip steel on the basis of fixed value control of the ductility, and the dynamically-distributed values are corrected and compensated according to the actual feedback values of the ductility. The invention provides a dynamic distribution control mode of the hydrochloric acid pickling line outlet ductility, the control accuracy of ductility is improved, the setting values of ductility need to be rapidly and accurately adjusted according to the variety of strip steel, and the ductility control modes of the withdrawal and straightening machine and a temper mill can be dynamically selected.
