AI Technical Summary

Technical Problem

The existing LF furnace electrode control system relies on feedback from a single electrical parameter, resulting in a single monitoring dimension, which cannot fully reflect the submerged arc state. Furthermore, it lacks multi-source data fusion and intelligent optimization, leading to large errors in electrode insertion depth estimation, weak anti-interference ability, slow response speed, and inability to adapt to the impedance characteristic requirements of different smelting stages.

Method used

The LF furnace electrode adaptive adjustment and control system adopts multi-source data fusion. By fusing electrical parameters, sonar detection and visual recognition signals, it dynamically corrects impedance, improves impedance matching accuracy and enhances anti-interference ability, and adapts to the needs of different smelting stages.

Benefits of technology

It improves the stability and impedance matching accuracy of submerged arc, optimizes the quality of molten steel and smelting efficiency, reduces energy consumption, and enhances the system's anti-interference capability.
