Why does the medium frequency electric furnace have insufficient power

Why does the medium frequency electric furnace have insufficient power when the equipment is normal? Today, the professional maintenance of the medium frequency electric furnace will tell you the reasons for this.

1. The medium frequency electric furnace and the power supply do not match, and the power supply will naturally be affected by insufficient power supply voltage.

2. If the rectifier part of the medium frequency electric furnace is not adjusted well and the rectifier tube is not fully turned on, the voltage will not reach the rated value, and the power of the equipment will be affected by the insufficient voltage.

3. If the voltage of the medium frequency electric furnace is set too high or too low, it will affect the power of the medium frequency electric furnace.

4. Excessive inductance exists in the output circuit of the medium frequency electric furnace. The additional inductance of the resonance circuit will cause interference to the power.

Reasons of furnace leakage and furnace wear accidents caused by medium frequency electric furnace:

(1) The molten iron is cooled for a long time, and the heat expansion and cold contraction. Extrusion of the furnace lining causes cracks in the furnace lining. During the melting process, the molten iron penetrates through the cracks, causing a furnace injection accident .

(2) The longer the medium frequency furnace is used, the thinner the furnace lining. As the amount of molten iron in the furnace increases, part of the bearing capacity decreases and the furnace wears.

(3)  Some impurities enter the furnace lining, causing the furnace to wear.

(4) The rapid cooling of the furnace lining produces cracks, which penetrate through the cracks during the smelting process.
