摘　　要：根据CSP生产线的轧制特点,结合Sims和Bland-Ford-Hill应力状态系数模型的结构形式,建立了优化的应力状态系数模型,并用其计算轧制力,结果表明,计算误差大大减小,平均相对误差为6.32%,较Sims和Bland-Ford-Hill应力状态系数模型均下降了50%以上,该模型能更准确地预报武钢CSP生产线各机架的应力状态系数,对于实际生产具有十分重要的理论意义和实用价值。According to CSP linePs rolling features, combined with Sims and Bland-Ford-Hill stress state coefficient models＇ structure type, an optimized stress state coefficient model was established to calculate rolling force. The result shows that the error decreases greatly, the average relative error is 6.32%, decreases by more than 50% comparing with Sims and Bland-Ford-Hill models. So the model can predict the stress state coefficient of WlSCO CSP line more precisely, and it has important theoretical significance and practical value to actual production.
