新一代高技術寬帶鋼軋機的板形控制

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

摘要: 提出界定軋機板形控制性能的輥縫調節特性空間（C_Q-C_H-q）及評價的主要參數：輥縫基本凸度及可調度、輥縫剛度、彎輥調控幅度、輥縫曲線四次分量可調度和輥間接觸壓力峰值.分析了板形控制的“柔性輥縫策略”與“剛性輥縫策略”.提出采用“交接觸長度（VCL）支持輥”以改善連軋機組的板形控制性能，并在生產中應用.

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.
