摘要
凸度检测技术可在线测量板带材的断面轮廓,并实时反馈到连轧控制系统中,实现凸度控制,在冶金工业中得到广泛应用。该项技术有厚度测量范围大、测量精度要求高的特点。本文从理论上分析了厚度测量精度的影响因素,建立了系统信号涨落模型,并在建成的凸度检测系统样机上进行了实验验证,理论与实验符合较好。
Instantaneous profile gauge technology has been widely used in metallurgy industry because it can on-line get the profile of steel strip.It has characters of high measure precision and wide measure range.The factors of thickness measure precision were analyzed and the system noise was simulated.Based on the analysis the system measure precision was estimated and validated in an experiment profile gauge system. The theory results fit experiment data very well.
