Abstract

The invention provides a real-time dynamic converter steelmaking quality prediction method based on data analysis. The method comprises the following steps: building a converter steelmaking quality off-line prediction model data base; respectively dividing liquid steel temperature and carbon element content into a plurality of stage ranges; building a real-time dynamic converter steelmaking quality prediction model; performing real-time dynamic converter steelmaking quality prediction according to the real-time dynamic converter steelmaking quality prediction model; testing the content of discharged steel components of the liquid steel; periodically updating the history data sets. The method provided by the invention is used for performing real-time dynamic prediction on liquid steel temperature and liquid steel quality during converter steelmaking on the premise of satisfying the technological requirements of converter steelmaking, can be used for tracking the condition inside a furnace in real time, and has the advantages of overcoming the defect of on-site delaying, improving the detection precision of each component content, lowering the production cost, also lowering the demand cost of equipment and providing valuable reference information for control of operators.

Description

technical field [0001] The invention belongs to the technical field of metallurgical steelmaking, and in particular relates to a real-time dynamic prediction method for converter steelmaking quality based on data analysis. Background technique [0002] Converter steelmaking is one of the important links in steel production. Its main goal is to smelt molten steel whose quality (mainly referring to the carbon content, silicon content, manganese content, sulfur content, and phosphorus content) of molten steel meets the requirements. Therefore, the real-time grasp of the temperature of molten steel and the state of various components in the smelting process has an important impact on the quality of molten steel. In this way, a prediction model of the entire smelting process of each element is required, and preparations are made before blowing to ensure safe operation. It goes smoothly and does not take up too many resources and increase costs. However, the quality information o...
