| Abstract: | Based on the Shougang revamping project and the characteristic of plate rolling process, a gap-set model of plate was developed by analyzing all the influencing factors, and the high precision model corresponding to them was got, such as the natural rigidity of plate mill, oil thickness etc.. The influence and its elimination of entry thickness to gap set model were also analyzed. On-line applications indicate that the gap-set model can improve the precision of set greatly and offer the base to thickness precision improvement and AGC system control. |
