新一代高技术宽带钢轧机的板形控制

Flatness Control in New Generation High-tech Mills for Wide Strip Rolling

摘要: 提出界定轧机板形控制性能的辊缝调节特性空间（C_Q-C_H-q）及评价的主要参数：辊缝基本凸度及可调度、辊缝刚度、弯辊调控幅度、辊缝曲线四次分量可调度和辊间接触压力峰值.分析了板形控制的“柔性辊缝策略”与“刚性辊缝策略”.提出采用“交接触长度（VCL）支持辊”以改善连轧机组的板形控制性能，并在生产中应用.

Abstract: The area of roll gap adjustment and its characteristics of stiffness are investigated in a C_Q－C_H－q space. Parameters for evaluating the capabilities of the roll gap control are defined.
