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 the rolling characteristics of CSP production line and the structural forms of Sims and Bland-Ford-Hill stress state coefficient model, the optimal stress state coefficient model is established and used to calculate the rolling force. The results show that the calculation error is greatly reduced and the average The relative error is 6.32%, which is more than 50% lower than the Sims and Bland-Ford-Hill stress state coefficient models. The model can predict the stress state coefficient of each rack in the CSP production line of WISCO more accurately, which is very important for actual production Theoretical significance and practical value.
