Abstract:According to the process characteristics and equipment components of a 1450mm pickling line tandem cold rolling mill (PL- TCM), the automatic control system with strip tracking, speed control and tension control as the core was developed. The entire tracking on the strip welding seam was realized, which laid the foundation for the full automation of continuous strip production line. The optimization algorithm of speed control was proposed, so that the production rhythm was more compact. A compound tension control method was adopted, which improved the precision of tension control. The system performed stable in operation after being put in use, which showed obvious optimization effect.
