The intermediate frequency furnace works normally, but the power does not increase the analysis and processing: the intermediate frequency furnace works normally, and only the intermediate frequency furnace of each component of the intermediate frequency electric furnace is in a good state. The IF power supply cannot go up mainly because:

1. The intermediate frequency furnace rectification is not fully open, and the rated DC voltage is not reached, which affects the output power.

2. The intermediate frequency voltage of the intermediate frequency furnace is adjusted too high and too low, affecting the power output.

3. The interception and interception values are adjusted improperly, resulting in low power output.

4. The furnace body and the power supply are not matched, which seriously affects the power output.

5. The intermediate frequency furnace compensation capacitor is configured too much or too little, and the power output with the best electrical efficiency and thermal efficiency is not obtained, that is, the optimal economic power output is not obtained.

6. The distributed inductance of the intermediate frequency output loop of the intermediate frequency furnace and the additional inductance of the resonant circuit are too large, which also affects the maximum power output.
