Abstract: By using the technique of Varying Contact-Length backup roll on SPM and corresponding simulation in finite element method, neural network on-line setting for processing parameters of tension leveller, analytic calculation of the stress field in the coil during the process of reeling with the iteration of layer by layer, optimization of processing parameters for reeling, and also by experimental investigation on site, a set of shape control techniques and technical counter measures were advanced. Applying these measures to CGL, good effect of shape control are obtained, and the quality of profile shape and the up-to-standard rate are also upgraded markedly. 

Key words:  skinpass mill(SPM), tension leveller; tension reel, strip shape, continuous galvanizing line(CGL)
