AI Technical Summary

Technical Problem

Existing technologies struggle to accurately predict furnace conditions during electric arc furnace smelting, especially during the switching between different smelting stages such as melting, oxidation, and reduction. They are unable to effectively characterize the high-order nonlinear relationships and continuous dynamic evolution characteristics among multiple operating parameters, leading to difficulties in electric arc furnace process optimization and energy consumption control.

Method used

A graph convolutional network-based approach, combined with Bernstein polynomial spectral filtering and neural controlled differential equations, is used to construct an electric arc furnace operating parameter graph. By combining the continuous-time multivariate state observation sequence with the graph-coupled state features, the complex nonlinear coupling relationship and continuous-time dynamic evolution of the multi-source operating parameters of the electric arc furnace are modeled.

Benefits of technology

It improves the accuracy and stability of electric arc furnace condition prediction, can adapt to inconsistent sampling frequencies and data gaps in industrial sites, enhances the ability to identify different smelting stages, and improves the operational stability and production efficiency of the electric arc furnace smelting process.
