| Abstract: | A mathematical model for dynamic operation is established according to the operating characteristics of reheating furnace. Temperature fields of slab at different delay time have been analyzed. Considering the gray characteristic of delay, the optimal strategies have been obtained by using the method of multi-target gray state decision. The results of simulation indicate that this method has good dynamic characteristics and is adaptive for on-line control. |
