Vanadium-titanium blast furnace comprehensive operation state evaluation platform and construction method thereof

Abstract

The invention discloses a vanadium-titanium blast furnace comprehensive operation state evaluation platform and a construction method thereof, and relates to the technical field of vanadium-titanium blast furnaces. When the platform is designed, personalized scoring rule setting is carried out for various indexes by consulting opinions and experiences of experts, so that each index has a corresponding data sensitive area and a corresponding data delay area when an evaluation score is calculated. And for the data sensitive region, the evaluation score changes severely, and the data slow region changes gently. Compared with a system in which all indexes are calculated according to a unified rule, the method has higher pertinence, the rules of all the indexes can be adjusted at any time, and potential relations between various core indexes and the comprehensive operation state of the vanadium-titanium blast furnace are more comprehensively constructed.

Description

Technical Field

[0001] The present invention relates to the technical field of vanadium-titanium blast furnaces, and in particular to a comprehensive operating status evaluation platform for a vanadium-titanium blast furnace and a construction method thereof. Background Art

[0002] The steel industry is the foundation and pillar industry in my country's national economy, and the long process represented by blast furnace-converter still dominates steel production. The stability, smooth operation, high efficiency and low consumption of blast furnaces are related to the economic benefits of the entire steel enterprise. At present, the technical level of blast furnace ironmaking has reached a bottleneck, and it is difficult to make a major breakthrough; with the vigorous development of data science and information technology, gradually applying big data technology to the blast furnace ironmaking process, making full use of the data accumulated in the ironmaking system to deeply analyze the production process, developing intelligent blast furnace ironmaking technology based on big data, and exploring the relationship between raw material conditions, process operation system and blast furnace operation status are important means to achieve energy conservation and emission reduction in blast furnace ironmaking and intelligent smelting.

[0003] The existing blast furnace operation status evaluation system mainly relies on the combination of big data, artificial intelligence and industrial Internet platform to form a data-driven intelligent technical solution. The industrial Internet platform collects and integrates multi-dimensional data in blast furnace production, such as raw material composition, operating parameters, equipment status, etc. Based on these data, the system predicts key parameters (such as furnace temperature and permeability index) by establishing artificial intelligence models such as neural networks, helping operators to optimize and adjust operations to ensure stable and efficient operation of the blast furnace. At the same time, the combination of expert systems and machine learning models further improves the accuracy of the evaluation. Quantitative indicators such as the antegrade index are also widely used in blast furnace operations. Through real-time analysis and monitoring of key parameters, the operating status of the blast furnace is quantified, which helps reduce fuel consumption and improve production efficiency.

[0004] The comprehensive operation status evaluation platform of vanadium-titanium blast furnace and its construction method are designed to design the evaluation algorithm model in accordance with the process index evaluation standards of the actual production of the enterprise, to allocate the weight and upper and lower limits of each index. The evaluation score obtained by the model can quantify and reflect the overall operation status of the vanadium-titanium blast furnace. Finally, a visualization platform for the evaluation model is built to facilitate the human-computer interaction between the blast furnace operator and the model. The platform can timely feedback the dynamic changes of the production indicators of the vanadium-titanium blast furnace, give early warning indications for the degradation indicators, and visualize and dynamically track all raw fuel indicators, assist the evaluation module, and scientifically guide the production of the vanadium-titanium blast furnace, thereby achieving cost reduction, efficiency improvement, energy saving and carbon reduction of the vanadium-titanium blast furnace.

[0005] Vanadium-titanium magnetite is currently widely used in major steel companies due to its high added value. However, due to the smelting characteristics of vanadium-titanium ore, vanadium-titanium blast furnaces have higher requirements for furnace temperature and slag emission control. In addition, compared with ordinary blast furnaces, vanadium-titanium blast furnaces have many unique indicators such as [Si+Ti] and (TiO2). The existing blast furnace evaluation system is only for ordinary blast furnaces, does not take into account the special smelting characteristics of vanadium-titanium ore, and does not involve indicators unique to vanadium-titanium ore smelting. This makes it impossible for ordinary platforms to accurately evaluate the production status of vanadium-titanium ore, may ignore key data points, and cannot effectively optimize the production process.

[0006] In addition, ordinary platforms usually use unified rules to evaluate all indicators, lacking personalized adjustments for vanadium-titanium ore-related indicators. It is impossible to accurately process the sensitive area data of each blast furnace process indicator to achieve more accurate status feedback and early warning, and ensure the stable operation of the vanadium-titanium ore blast furnace. In addition, the number of indicators evaluated by ordinary platforms is limited, and it is impossible to evaluate the overall operating status of the blast furnace more extensively and comprehensively.

[0007] Therefore, a new solution to the above problems needs to be proposed. Summary of the invention
