Abstract

The invention provides a real-time dynamic prediction method of converter steelmaking quality based on data analysis, which includes: establishing a converter steelmaking quality offline prediction model database; dividing the molten steel temperature and carbon element content into several stage ranges, and establishing a real-time converter steelmaking quality Dynamic prediction model; perform real-time dynamic prediction of converter steelmaking quality based on the real-time dynamic prediction model of converter steelmaking quality; inspect the molten steel tapping composition content; and regularly update historical data collections. On the premise of ensuring that the requirements of the converter steelmaking process are met, the present invention performs real-time dynamic prediction of the molten steel temperature and molten steel quality during the converter steelmaking process, can track the conditions in the furnace in real time, and overcomes the defect of on-site delay and lag. It improves the detection accuracy of the content of each component, reduces production costs, and also reduces the cost of equipment requirements, providing valuable reference information for operator control.

Description

technical field [0001] The invention belongs to the technical field of real-time dynamic prediction of converter steelmaking quality, and specifically relates to a real-time dynamic prediction method of 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. ...
