How to improve the power factor of the medium frequency furnace in a hardware foundry, save on electricity costs, and shorten the smelting cycle?

Time：

2019-01-05

Load of the hardware foundry: 3 units of 1.5-ton medium frequency furnaces, 2 in use and 1 as backup. 1. Power factor: The power factor has been improved from 0.88 to over 0.95, saving about 2% on electricity costs, and significantly shortening the smelting cycle; 2. Filtering effect: The harmonic currents of the 5th, 7th, and 11th orders have been reduced to 1.7%, 1.5%, and 1.2%, respectively; 3. Temperature noise: The operating temperature and noise of the transformer have been significantly reduced, enhancing the transformer's load-bearing capacity and extending its service life.
