摘　　要：从分析热带连轧机组现场观察到浪形与带钢之间的相对运动现象入手,提出了飘波、固浪、驻浪的概念,给出了飘波定义。研究表明:飘波起源于精轧末架出口,经辊道周期性冲击作用得以维持和加强,指出可能出现驻浪的条件是辊道间距等于波长的整数倍。飘波的出现会导致用三角法测量板形时出现误差,而新型截光法板形仪可减轻或消除此误差。Based on the analysis of relative motion between wave and strip during hot strip rolling, the conception and definition of flying wave,staying wave and fixed wave are given. The study results show that the flying wave appears at the exit of the final stand, and is sustained and strengthened by the periodic impact of roller table. The condition of staying wave formation is the pitch of transfer rollers being the multiple times of wavelength. The occurrence of the flying wave can lead to the error in shape control by shape meter using laser triangle method, but the er ror can be decreased or eliminated by laser capture method.
