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.
