Abstract：Harsh environment in blast furnace poses a huge challenge for direct measurement of burden surface. Under special restrictions of high temperature，dust and strong vibration of air impact，a novel measuring system of burden surface in blast furnace which can be used to real-time measuring is developed based on mechanical reciprocating swing radar. This study presented a detection method of quasi constant false alarm threshold which is suitable for the echo detection of burden surface. An effective algorithm to calculate the radial shape curve of burden surface is concluded，in combination with the energy center of gravity method and cubic spline interpolation. The real-time measuring and visualization of the radial shape curve of burden surface is achieved by 3D imaging technology. Aiming at the typical applications of a 2 650 m3 blast furnace in an Iron and steel company for the first time，this system achieved a rounded system architecture of industrial radar measuring， data transfer，imaging algorithm and material shape classification .The system makes it possible to measure the furnace burden distribution of any section under harsh environment in blast furnace. It provides data support for optimization of fabric control，efficient gas utilization，energy conservation and emissions reduction.
