Electric arc melting anomaly detection method

The invention belongs to the technical field of vacuum electric arc furnace smelting titanium ingot production, and particularly relates to an electric arc smelting anomaly detection method which comprises the steps that S1, a plurality of high-resolution automatic zoom cameras are fixed to the top of a furnace; s2, the furnace body is closed, a vacuum system is started, and after a molten pool is stable, the system automatically collects normal smelting image data through a high-resolution automatic zoom camera and stores the normal smelting image data in a register; s3, electric arc detection is carried out, and a high-definition picture of the real-time smelting furnace image data is compared with a normal standard picture; s4, in a feeding mode, the cast ingot is cooled, vacuum breaking is conducted after 9-12 h, and the cast ingot is taken out. Manual observation and judgment can be completely replaced, the risks of furnace water leakage, crystallizer burnout and even explosion caused by the fact that ma
