The invention relates to a roll bending optimization setting method, and belongs to the technical field of hot continuous rolling methods. According to the technical scheme, a roll bending force setting range of a specific rack of a four-roll CVC hot rolling unit is considered, a roll bending optimization setting model is established on the basis of three parameters including an inter-roll pressure distribution value, a rolling pressure distribution value and a plate shape, the model is solved, and the optimal roll bending force setting value in the strip steel rolling process under the specific specification is obtained. The method has the beneficial effects that the plate shape control capacity of the CVC hot rolling unit under the specific rack is improved, and good economic benefits are brought to on-site strip steel production. 本发明涉及一种弯辊优化设定方法，属于热连轧方法技术领域。本发明的技术方案是：考虑四辊CVC热轧机组特定机架的弯辊力设定范围，基于辊间压力分布值，轧制压力分布值及板形这三个参数，建立弯辊优化设定模型，并对该模型进行求解，得到特定规格下带钢轧制过程的最佳弯辊力设定值。本发明的有益效果是：提高了CVC热轧机组特定机架下的板形控制能力，为现场带钢生产带来了较好的经
