冷轧四辊轧机弹性变形在线模型
Online model research for elastic deformation of 4-high cold mill
摘要
Abstract
In order to improve the mill spring calculation accuracy,a new online elastic deformation model for 4-high cold mill was put forward.In the model,the mill elastic deformation was divided into two parts,i.e.rolls elastic deformation and mill housing elastic deformation.Combining all the influence factors,the model structure of rolls and mill housing elastic deformation were designed.Based on the proposed model structure and test scheme,aiming at a 1 800 mm single-stand reversible cold mill,the effect of every factors on the rolls elastic deformation,such as back-up roll diameter,work roll diameter,strip width,rolling force and bending force,were obtained by means of influential function method,and the online model of rolls elastic deformation was established.Based on the actual test data of a single-stand cold mill,the coefficients of mill housing elastic deformation model were obtained,and the proposed mill elastic deformation model was applied in this mill.The results indicate that the calculation deviation of roll gap value is within ±0.1 mm,which shows that the model is accurate and it can meet the requirement of online process control.关键词
