Abstract In allusion to the case that the on-line prediction of strip transverse tension distribution in CAPL cannot be realized，strip wandering，buckling and shape evolving cannot be warned which may lead to breakage. Taking into account the equipment and technological characteristics of CAPL，the CAPL strip tension distribution model was built and the relevant calculative strategy was given，on the foundation of analyzed the influence of the strip transverse temperature difference，the incoming strip shape，the furnace roll profile and the furnace roll perpendicularity and levelness error to the longitudinal elements deformation. Taking a CAPL of Baosteel Stainless Steel as an example，the influence of original furnace roll profile，incoming strip shape，transverse temperature difference，furnace roll perpendicularity and levelness error and assigned tension to the strip transverse tension distribution are analyzed. The forecast software of strip transverse tension distribution and shape evolving in passing of CAPL are compiled and applied to production and practice，which achieves good results，with further popularization and application value.
