Abstract

The coiling temperature control method of a typical hot strip mill was investigated. Based on Time-Velocity-Distance (TVD) curve, the generation of velocity deviation between the calculated and measured was present and discussed in detail. To deal with the deviation of velocity, the main cooling zone was divided into two parts by the medium pyrometer, and the feed forward model was triggered under finishing pyrometer and medium pyrometer respectively for one strip segment. The temperature deviation of feed forward setup under finishing pyrometer could be corrected by the feed forward setup under medium pyrometer effectively. Application results indicated that the control precision of coiling temperature on different steel grades had been improved to varying degrees, and the highest point was up to nearly 4%.
