Abstract

The invention discloses a method for monitoring the state of a blast furnace taphole. S1: collecting image data of a blast furnace taphole to obtain a blast furnace taphole image; S2: sequentially performing interception, morphological opening operation, Gaussian operation based on the blast furnace taphole image Fuzzy, K-Means color clustering, grayscale transformation, threshold segmentation and morphological operations to obtain blast furnace molten iron characteristic images; S3: Perform image data analysis based on blast furnace molten iron characteristic images to obtain analysis data; S4: Calculate based on analysis data , respectively, to obtain the size, depth, penetration time, amount of tapped iron and filling amount of blast furnace taphole. By intelligently monitoring the state of the tap hole of the blast furnace, the present invention has high accuracy and short running time, and can meet the requirements of safe and stable production on the blast furnace ironmaking production site; the present invention has feasibility and superiority. The monitoring method is more scientific, and the monitoring results are more accurate. Accurate; the monitoring process is automated, no manual operation is required, and personnel redundancy is reduced; the safety of the operating area in front of the furnace is improved.

Description

technical field

[0001] The invention belongs to the field of metallurgical blast furnace ironmaking, and in particular relates to a state monitoring method and system for a blast furnace taphole. Background technique

[0002] The development of the iron and steel industry is one of the important pillars of national development, and large blast furnaces, as important production equipment for steelmaking, have an irreplaceable role. The intelligent monitoring of the state of the blast furnace taphole is very important to the production quality of the blast furnace and its own life.

[0003] At this stage, mainly through the operator's observation and combined with their rich experience, a comprehensive judgment of whether the blast furnace tap hole has been penetrated is made, but this judgment method is relatively rough, and it is also more dangerous to work in the working area in front of the furnace. Therefore, this paper proposes a method to integrate and process image da...
