摘　　要：大尺寸环件毛坯在高温下轧制成型,为控制环件毛坯的形状、尺寸,需对环件进行在线测量,由于被测工件温度高,故采用激光非接触式测量。文章采用直射式激光位移三角法测量环件厚度,用激光测距法测量环件外径和内径,分别讨论了直射式三角法测量原理和激光测距原理;针对被测工件温度高以及环境温度高的特点,分析了温度对测量精度的影响,提出了提高测量精度的措施。Big size blank ring under high temperature rolling forming, for control blank ring shape, size,should online measurement, the high temperature being measured, so using laser displacement triangulation non-contact measurement. In this article ,using the direct type laser displacement triangle method to measure the thickness of the ring, the ring outside and inside diameters measured by laser ranging. According to the high temperature being measured and the surrounding environment higher characteristic ,analyzes the influence of temperature on measuring accuracy and puts forward the improvement measures.
