【摘要】：为提高轧机弹跳值的计算精度,开发一种四辊轧机弹性变形的在线计算模型,模型中将轧机弹性变形分为辊系弹性变形和轧机牌坊弹性变形;综合考虑各影响因素,设计辊系和轧机牌坊弹性变形的模型结构。基于所设计的模型结构和测试方案,针对某1 800 mm单机架可逆冷轧机,采用影响函数法得到支撑辊辊径、工作辊辊径、带钢宽度、轧制力和弯辊力等因素对辊系弹性变形的影响,并建立辊系弹性变形在线模型;通过对轧机的现场测试,回归得到轧机牌坊弹性变形模型中的系数,并应用于该机组中。研究结果表明:采用该模型,辊缝设定值的计算偏差可控制在±0.1 mm以内,表明该模型具有较高的计算精度,满足现场控制要求。
[Abstract]:In order to improve the calculation accuracy of the spring value of rolling mill, an on-line calculation model of elastic deformation of four-high mill is developed. In the model, the elastic deformation of rolling mill is divided into roll elastic deformation and rolling plate elastic deformation. The model structure of elastic deformation of roll system and mill arch is designed. Based on the designed model structure and test scheme, for a 1 800 mm single stand reversible cold rolling mill, the influence function method is used to obtain the diameter of the supporting roll, the diameter of the work roll and the width of the strip steel. The influence of rolling force and bending force on the elastic deformation of roll system is established, and the on-line model of elastic deformation of roll system is established, and the coefficient of elastic deformation model of the plate of rolling mill is obtained by the field test of rolling mill, and applied to the mill. The results show that the calculation deviation of the set value of roll gap can be controlled within 卤0.1 mm by using this model, which indicates that the model has higher calculation accuracy and meets the requirements of field control.
