热轧无缝钢管在线精度测量是近年来为了提高无缝钢管质量采取的一项新技术。但是，由于热轧 环境十分恶劣，难以应用现有的精度测量装置。叙述了热轧无缝钢管在线测厚装置的进展情况及 近期作者研究开发的方案。
Hot rolled seamless steel pipe online precision measurement in recent years in order to improve the quality of seamless steel pipe to adopt a new technology. However, due to the hot rolling environment is very poor, it is difficult to apply the existing accuracy measuring device. The progress of on-line thickness measuring device of hot-rolled seamless steel pipe and the scheme of recent author’s research and development are described.
