Description

technical field [0001] The invention relates to the field of radar level scanners, in particular to a 3D radar scanner for blast furnace charge level imaging and a blast furnace charge level detection system. Background technique [0002] Blast furnace production is an important part of iron and steel smelting, and a good shape of the material surface inside the blast furnace is of great significance to improve production efficiency and reduce combustion ratio. However, the internal working environment of the blast furnace is extremely harsh: high temperature, high pressure, large dust, and high gas concentration inside contains adhesive tar, which brings great difficulties to the measurement of the material level. [0003] In order to control the uniform distribution of the charge level of the blast furnace, it is necessary to clearly understand the distribution state of the charge level in the blast furnace. At present, most of the detection methods for blast furnace mate...

Problems solved by technology

Among them, although the radar probe and the mechanical probe are accurate and reliable, they cannot traverse every point of the blast furnace charge surface, and the uneven distribution of the charge surface in the blast furnace makes the measured data unable to reflect the distribution of the entire charge surface

The kiln video monitoring system can see the state of the material distribution in the furnace, the development of the flame in the furnace and the flame at the side of the furnace at high temperature, but when the light is dark and the material level is very low, the distribution of the material in the furnace cannot be seen.

The infrared imaging technology is to analyze the infrared image of the surface of the charge surface, and indirectly calculate the distribution of the charge surface of the blast furnace by detecting the temperature distribution of the charge surface. It can construct a three-dimensional image according to the pixel value and the relationship between the pixels, and fully reflect the furnace top. The shape of the material surface, but the effect is not good in the low temperature area

The current detection methods of the above-mentioned blast furnace charge level have certain limitations.
