A Method for Composite Roll Profile Control Based on Quintic CVC and SmartCrown

Abstract

Abstract:

In order to improve the profile control capability of rolling mill,based on the analyses of characteristics of continuously variable crown(CVC) roll contour and SmartCrown roll contour,a method for composite roll profile control was proposed based on quintic CVC and SmartCrown.Combined with the characteristics of quintic CVC and SmartCrown in the control of profile defects,these methods of decomposition and superposition were used to redefine its quadratic crown and quartic crown and control capability.Through the design example and result analyses,it demonstrates that the method effectively improves the disadvantages of profile control due to the larger roller diameter difference to the quintic CVC and advanced variable crown(AVC) roll contour.

Key words: composite roll, profile control, crown, decomposition, superposition

摘要：

为改善轧机的板形调控能力，在分析连续变凸度CVC辊型和SmartCrown辊型特性的基础上，提出了一种基于五次CVC和SmartCrown的复合辊型的板形控制方法。将五次CVC和SmartCrown辊型在控制板形缺陷方面的特性相结合，采用分解与迭加的方法重新确定其二次和四次凸度及调控能力。通过设计实例和效果分析验证，表明该方法有效改善了五次CVC和AVC辊型因辊径差较大不利于板形控制的缺点。
