The low-frequency power supply device for metallurgical ore furnaces independently developed and produced by the company (patent number: ZL 97 2 26494.9) uses a low-frequency power supply with a frequency of 0.01~3Hz for power supply, and the current is very close to DC. Therefore, it has many advantages of DC ore furnaces and does not have a bottom electrode or arc deviation. It has the advantages of both power frequency and DC submerged arc furnaces, overcomes their disadvantages, and has low renovation costs and short investment return period.
