Embodiment 1
[0044] This embodiment provides a method for blast furnace state clustering, such as figure 1 As shown, the method includes the following steps:
[0045] Step 110, collecting process parameters of the state of the blast furnace, and performing preprocessing on the process parameters.
[0046] In this step, before collecting the process parameters of the state of the blast furnace, it is necessary to describe and characterize the state of the blast furnace to determine the process parameters.
[0047]Specifically, the state of the blast furnace mainly includes: gas flow state, tapping state and blast furnace body state. Among them, the gas flow state of the blast furnace mainly reflects the development of the gas flow, and the total pressure difference of the blast furnace reflects the strength of the overall gas flow. The top temperature of the blast furnace roof reflects the strength of the core airflow. The gas flow rate, flow rate and ventilation degree of the whole furn...
Embodiment 2
[0113] Corresponding to Embodiment 1, this embodiment also provides a blast furnace state clustering device, such as image 3 As shown, the device includes: an acquisition unit 31, an extraction unit 32, an analysis unit 33 and a clustering unit 34; wherein,
[0114] The collection unit 31 is used to collect the process parameters of the state of the blast furnace and preprocess the process parameters; here, before collecting the process parameters of the state of the blast furnace, it is necessary to describe and characterize the state of the blast furnace, Determine process parameters.
[0115] Specifically, the state of the blast furnace mainly includes: gas flow state, tapping state and blast furnace body state. Among them, the gas flow state of the blast furnace mainly reflects the development of the gas flow, and the total pressure difference of the blast furnace reflects the strength of the overall gas flow. The top temperature of the blast furnace roof reflects the s...

Abstract
The invention provides a method and device for clustering the states of a blast furnace. The method comprises the steps that process parameters of the states of the blast furnace are collected and preprocessed; state feature data of the process parameters is extracted; the state feature data of the process parameters is subjected to linear correlation analysis, and the linear correlation result between the state feature data is determined; when it is determined that the linear correlation result shows linear independence, a K-means algorithm is utilized for clustering the state feature data, and the clustering result of the states of the blast furnace is acquired; and thus, the states of the blast furnace are precisely divided according to the clustering result, and correlation analysis of operation and indexes can be carried out conveniently so that a blast furnace superintendent can grasp the current state of the blast furnace to precisely guide blast furnace operation.
Description
technical field [0001] The invention belongs to the technical field of blast furnace ironmaking, and in particular relates to a method and device for blast furnace state clustering. Background technique [0002] Iron is known as "industrial food". The iron and steel industry has long been the basic industry of the national economy of all countries in the world, and it is an important symbol to measure the national economic level and comprehensive national strength. [0003] Blast furnace is the main method of modern ironmaking. There is a gap between my country's ironmaking production technology and the international level, which is mainly reflected in the level of detection, control and optimized operation. The physical and chemical reaction process inside the blast furnace is extremely complex, involving various phases of various substances. The mechanism of the smelting process is not completely transparent, and many important internal information cannot be directly meas...
