高炉雷达料面测量信号处理系统改进
Improvement of a radar signal processing system for burden surface measurement in a blast furnace
摘要
Abstract
Metallurgical radar was developed which can be used in high temperature and hash production environments. It adopted an improved frequency-modulated continuous wave principle and enhanced the real-time performance of solid material level measurement. An intelligent time-varying threshold signal processing method was proposed to solve the radar ranging accuracy problem caused by the change of solid material surface reflection coefficient in a blast furnace. Measurement results in a solid-powder state material surface simulation environment in the laboratory shows that the measurement tracking delay of the metallurgical radar is within 0. 2 s, and the maximum average tracking error is less than 0.05%. Field test results show that the average measurement error is 0. 95% , indicating that the metallurgical radar is capable of stable material surface tracking in real-time and can meet the requirements of BF monitoring.关键词
