Automatic smelting control method of continuous charging electric arc furnace

The invention belongs to the technical field of metallurgical equipment, and relates to an automatic smelting control method of a continuous charging electric arc furnace. According to the method, in the smelting process, the real-time smelting working condition in the electric arc furnace is judged according to the result of real-time sonar detection conducted on sound emitted by the electric arc furnace through the sonar detection system and the result of real-time image recognition conducted on the image result in the electric arc furnace through the image recognition system; and the power of the power supply system and the conveying speed of the feeding system are correspondingly adjusted according to the judgment result of the real-time smelting working condition in the electric arc furnace, dynamic matching of the power supply system and the continuous feeding system in the smelting process is achieved, and then automatic smelting control over the continuous feeding electric arc furnace is achieved.
