The invention provides an automatic temperature control method for a rod material cold control system, and belongs to the technical field of rod material heat treatment. The method comprises the following control steps including temperature detection treatment: the effective value of actual temperature detection equipment is judged, and the actual detection value is corrected; automatic temperature regulation: the automatic temperature regulation is realized on the temperature after the pre-cooling section before the rod material fine rolling, and the automatic temperature regulation is realized on the cold bed inlet temperature of the rod materials. The problems of temperature control precision and stability of the rod materials are effectively solved. The method has the advantages that all cold control equipment realizes the automatic operation, and the distribution of the core part temperature and the surface temperature of the rod materials after the cold control automatic control is stable, so the intensity and the toughness of steel materials are improved, the steel material tissue is improved, and in addition, electric energy sources and water energy sources are saved through automatically controlling a cooling water pump and a valve group.
Description
technical field [0001] The invention belongs to the technical field of bar heat treatment, and in particular relates to an automatic temperature control method of a bar cooling system, which is a fully automatic control method for bar cooling based on the combination of traditional PID adjustment, self-learning and fuzzy control. Background technique [0002] In the modern bar production line in the 21st century, the bar cooling device is a very important part. It is usually installed between the bar rolling mills or after the finishing mill to control the temperature of the bar rolling process and Finished product cooling temperature control to achieve the purpose of improving product performance. With the continuous advancement of technology, the requirements for the automation control level of producing high-strength and low-cost rods are getting higher and higher, and the traditional temperature control methods can no longer meet the requirements. The traditional bar co...
