三辊连轧管机架轧辊孔型的在线测量与校正

On-line Measurement and Calibration of Roll Pass of 3-roll Mandrel Pipe Mill

摘要: 为了实现连轧管机组轧制机架孔型的在线测量，提高孔型控制精度和对中作业效率，引入了在线摄像机孔型测量分析系统CaliView，并与其他中心线测量方法进行对比。分析认为：CaliView 实现了机架孔型精度的在线测量和调整，精度高（精度为0.01 mm），测量方法快捷，数据可直接分析显示，可作为新型连轧孔型中心线测量校正的手段，提高了中心线检验校正的频次和精度。

Abstract: The camera-based on-line roll groove measurement/analysis system,CaliView is introduced to realize the on-line measurement of the roll stand pass of the mandrel pipe mill so as to improve the pass control precision,and the central-line calibration efficiency. And this method is compared and analyzed with other central-line measurement methods as used before. It is regarded via the analysis that the said CaliView system is capable of on-line measurement and calibration of the roll stand pass with high precision(precision class:0.01 mm). The measurement method features fast and convenient operation,and direct data analysis and display,being worth using as a new method for measuring and calibrating the pass central line of the mandrel pipe mill with higher frequency and precision.
