基于非圆弧理论的平整机轧制力简化模型

摘要

针对目前带钢平整机轧制力模型的缺点，综合考虑带材的弹性变形与塑性变形，基于非圆弧轧辊理论的大量计算结果，回归得到一套冷带钢平整机轧制力简化模型.该模型可用于干平整或湿平整轧机设计、轧制规程制定.4个典型算例的计算结果表明，简化模型与非圆弧轧辊理论计算结果一致.最终通过2套平整轧机的实测轧制力验证了简化模型的正确性.%In view of the disadvantages of the rolling force model for temper rolling mill,consider-ing the strip’s elastic and plastic deformation,a simplified rolling force model for cold temper rolling mill was put forward based on a lot of calculation results of non circular arc theory.The simplified rolling force model could be used to mill designing and developing procedures for both dry and wet temper rolling mill.The results of 4 typical examples show that the simplified rolling force model is in well agreement with the non circular arc theory.Finally,the simplified model’s correctness was veri-fied by the measured rolling force of 2 temper rolling mills.
