Application of Advanced Technology Packages for Improved Strip Profile and Flatness in Hot-strip-mills

使用先进的工艺模型可以精确计算工作辊弯辊和窜辊等辊缝执行机构所需要的设定 ,从而在考虑轧机中物料横向流动行为以及热应力对工作辊凸度影响等条件下确保优化辊缝形状。

With the use of advanced process models the required settings of roll-gap actuators such as work-roll bending and shifting can be accurately calculated to ensure an optimum roll gap shape, taking into account the material cross flow in the mill and the influence of thermal stresses on the thermal crown of the work roll. This paper describes the latest technological packages and process models developed by VAI for improved strip profile and flatness in hot-strip mills.
