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.

First, this paper presents three girders model with double cable planes which main girder and side girder is connected by rigid arms, analyzes the dynamic characteristic of Yonghe cable-stayed bridge and obtains its natural vibration modes (i.e., frequency, damping values and the mode shapes ) by ANLSIS structural analysis program and uses these parameters as dynamic dactylogram of the intact case of cable-stayed bridge. Using the passage of random as the ambient vibration ,the dynamic properties of Yonghe Bridge is measured and the modal parameter of its 15 years after is identified and used as dynamic dactylogram of the damaged case. By the finite element analysis and locale vibration test, damaged and undamaged modal parameter is analyzed and curvature mode shape, which is sensitive to damage state, is introduced as possible candidate for identifying and locating damage in the cable-stayed bridge. Selecting the branch of part measured point from modal parameter, this paper deduces the damaged index which can detect the possible damaged location of the cable-stayed bridge deck and identifies the damaged region and degree for Yonghe Bridge. For the purpose of structural condition monitoring in in-situ , from another viewpoint, this paper introduces the method called the best optimization vector to detect damaged location and degree. The accuracy and reliability of the method presented in this paper are demonstrated by static analysis and test and the healthy state of Yonghe Bridge can be evaluated.
