Outline
The operation stability of strip steel in production line of continuous annealing directly affects the surface quality, dimensional accuracy and efficiency of production line. In order to reveal the effect laws of single side wave shape and asymmetric center wave on sensitivity to deviation, the explicit simulation model of power for single furnace roller is established to systematically evaluate the effects of such parameters as wave height, wave length and wave width on deviation of strip steel. The results showed that the larger the wave height, the greater the deviation at fixed position and the maximum sensitivity was at wave height (H) of 4~9 mm; the greater the wave length and wave width, the smaller the deviation as well as sensitivity was significantly increased when wave width was below 300 mm. These findings could provide the basis for strip shape quality control of incoming materials and improvement of deviation in continuous annealing as well as quantitative references for roll shape optimization and selecting online corrective parameters, which are helpful to improving the operation stability of unit and product quality.
