[0033] In the embodiment, the technical defects of the traditional process are effectively solved by the intelligent control method: the raw material pretreatment link realizes accurate control of moisture (0.8%-1.2%), the positioning accuracy of feeding is 1 cm, which lays a foundation for stable operation of the electric furnace; the response speed of electrode adjustment is improved to 0.1 seconds, combined with the molten pool state prediction model, the arc breaking accident is reduced by more than 95%; the innovative three-dimensional molten pool monitoring technology makes the slag-iron interface identification accuracy reach 2 cm, and the three-phase power balance deviation is controlled within 1.5%; the intelligent energy efficiency optimization system reduces the power consumption per ton of phosphorus to below 10500 kWh, which is more than 12% lower than the traditional process; the automatic material distribution system realizes layer thickness control accuracy of ±1 cm, and the material surface flatness reaches 0.5 cm; the multi-parameter linkage safety mechanism shortens the emergency response time to within 50 ms, greatly improving the production safety.

After the infrared thermal imager data is compensated by the temperature compensation unit to eliminate the interference of smoke and dust, it is input into the three-dimensional reconstruction unit synchronously with the slag-iron interface scanning data of the microwave radar to generate a dynamic model of the molten pool thermodynamics. The central control system calculates the three-phase power deviation value in real time based on the model, and outputs the current phase correction instruction to the electric furnace transformer when the deviation is greater than 1%. The dynamic energy efficiency optimization module 77 accesses the real-time electricity price data and the load prediction database of the power grid, and the digital twin model generates a load scheduling strategy in combination with the electric furnace operating state (including the electrode wear coefficient and the furnace lining thickness data): during the trough period, the load is increased to 105% and the electrode automatic compensation program is started to offset the insertion depth deviation caused by overload; during the peak period, the load is switched to 90%, the non-core power consumption units are closed synchronously, and the steam production of the waste heat boiler is increased by 20% to drive auxiliary equipment.
