针对以往连退过程中对带钢内部应力横向分布情况无法在线预测，从而对连退过程中的跑偏、瓢曲以及带钢在各工艺段的板形演变无法在线预警、容易造成断带缺陷的问题，充分结合连退机组的设备与工艺特点，在研究了带钢横向温度差、来料板形、炉辊辊型、炉辊水平度与垂直度误差对带钢内部单元变形影响模型的基础上，建立了一套适合于连退过程的带钢内部张力横向分布模型，给出了相应的计算策略，并以宝钢不锈钢有限公司某连退机组为研究对象，定量分析了炉辊原始辊型、来料板形、横向温差以及炉辊水平度与垂直度误差、设定张力等因素对连退过程带钢内部张力横向分布的影响，编制出了相应的“连退机组通板过程带钢内部应力横向分布及板形演变预报软件”，并将其应用到生产实践，取得了良好的效果，具有进一步推广应用的价值。

In allusion to the case that the on-line prediction of strip transverse tension distribution in CAPL cannot be real-ized,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 longitudi-nal 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 as-signed tension to the strip transverse tension distribution are analyzed. The forecast software of strip transverse tension dis-tribution 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.
