Description

technical field

[0001] The invention relates to an intelligent prediction system for continuous casting slag based on a hierarchical real-time memory algorithm, and belongs to the technical field of artificial intelligence. Background technique

[0002] Continuous casting ladle slag detection technology is one of the important means to control the purity of molten steel and improve the quality of castings and the yield of molten steel by effectively identifying the state of molten steel in the later stage of ladle pouring.

[0003] In recent years, many scholars have done a lot of research on ladle slag detection methods. In 2010, Tan Dapeng et al. realized the automatic monitoring of continuous casting slag through artificial neural network technology; in 2012, Li Pengfei et al. proposed a method based on wavelet decomposition, The automatic detection method of molten steel continuous casting slag combined with chaos analysis and RBF neural network realized the automatic id...
