Problems solved by technology

However, since the above two methods have too few monitoring points, they cannot cover every point of the furnace top material surface, which makes it very difficult to analyze and grasp the distribution of the material surface in the furnace. The operator's experience can only be used to guess the material surface distribution of the blast furnace The state of airflow and airflow brings great randomness to the operation of the blast furnace, and the accuracy cannot be guaranteed, let alone the optimization of the material distribution operation;
[0006] Method 3 uses infrared imaging technology to analyze the infrared image of the material surface, and indirectly calculates the distribution of the blast furnace material surface by detecting the temperature distribution of the blast furnace material surface. Although this method can form a three-dimensional image based on the pixel value and the relationship between pixels , which fully reflects the shape of the furnace top material surface, but in fact there is a problem that the temperature does not correspond to the height of the material surface, and even if the relationship between temperature and height is corresponding, it can only be qualitative and cannot be quantified

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a blast furnace material level radar scanning 3D imaging device, a monitoring system and a monitoring method thereof. Background technique [0002] In the blast furnace ironmaking production process in the metallurgical industry, blast furnace material distribution is one of the most important links in the blast furnace ironmaking system. Accurate and effective grasp of the distribution of the material surface in the blast furnace is a prerequisite for ensuring the normal production and operation of the blast furnace and product quality. [0003] The measurement of blast furnace charge level has been a difficult problem for a long time.
