In order to increase production efficiency and reduce energy consumption, the control method of automatic frequency adjustment is often adopted during the smelting process of medium and large volume intermediate-frequency furnaces, causing serious sub-harmonic pollution of frequency shift. The generating mechanism of the phenomenon was qualitatively analyzed, which had been proved by test data from actual projects, to provide helpful refer-ence for the design and implementation of electricity quality treatment projects for similar e-quipment.
