A new kind of industrial high temperature radar has been developed, which is used for real-time monitoring of the burden surface under the harsh environment inside blast furnace (BF) and observing the decline rate of the burden surface. This radar technology is also used for determination of the burden profile through multi-point arrangement of the radars. The 26GHz frequency radar is introduced with the FMSW structure of the hardware model, as well as the heat and dust resistant solid burden surface algorithm with the monitoring range of 0-100 meter and the measurement accuracy of 1%, a specially designed ceramic antenna with the temperature range of 0-600 degree, and the drift < 0.1% / year. Six industrial high temperature radars have been installed on the top of the BF at the industrial field, and optimized the radar installation location through electromagnetic simulation. The real-time image of the burden surface has been obtained by surface fitting and digital simulation of the data from the six-point radars. The effective application of this technology has improved significantly the fluctuation of burden surface, the production of BF, the energy saving and gas emission reduction.
