Secondly, aiming at the difficulty of information sharing between reheating furnace and roughing mill which is brought by the separate control of the two facilities, and the problems of exceeding energy consumption and low security of rolling process given by the difficulty to adjust the heating process of slab dynamically, this paper presents a comprehensive optimizing control strategy of reheating furnace based on the rolling information feedback. In the presented strategy, fuzzy control and neural network are used to feed roll force and slab temperature of therolling process back to reheating furnace and the concrete furnace temperature setting compensation value can be worked out. So that the heating process of slab can be adjusted dynamically according to the heating quality of the slab, and energy consumption can be reduced, the rolling security can be ensured as well.
