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;

Abstract

The invention discloses a blast furnace charge level radar scanning 3D imaging device and a monitoring system and a monitoring method thereof. The imaging device is installed on a furnace wall on one side above a blast furnace; real blast furnace charge level scanning information of thousands of points is provided within several seconds through a most advanced radar probing technology and 360-degree holographic scanning; the real state of the blast furnace charge level is monitored in real time, and a charge level three-dimensional image is generated; by adopting the monitoring system and the monitoring method formed by the imaging device, the unsymmetrical material distribution state and the distribution of descending speeds of material charge levels can be detected online in real time, the material distribution information feedback is substantially improved, and technology analysis reaches a new altitude level; and to sum up, the blast furnace charge level radar scanning 3D imaging device and the monitoring system and the monitoring method thereof have the beneficial effects that real-time online detection precision is high and performance is stable, the technical problem that the height and the surface shape of the current blast furnace charge level cannot be accurately measured easily is solved, and optimized operation and reasonable material distribution are performed on the blast furnace.

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. At present, there are roughly three methods for measuring the blast furnace charge level: [0004] Method 1. Traditionally, mechanical probes are used to collect data for monitoring the material level of closed blast furnaces. Each blast furn...
