本文结合热轧圆钢椭圆度在线测量仪的研制,介绍了一种提高动态测量精度的方法——激光扫描测径比较法;讨论了恶劣环境下的抗干扰和防污染措施;分析了各种因素引起的测量误差,提出了修正、减小或消除的途径。
In this paper, a method to improve the accuracy of dynamic measurement is introduced in this paper based on the development of the on-line measuring instrument of hot-rolled round oval. The method of laser scanning caliper comparison is introduced. The anti-interference and anti-pollution measures in harsh environment are discussed. Factors caused by the measurement error, put forward to amend, reduce or eliminate ways.
