How to design an induction melting furnace to save electricity?

1. O forno de fusão por indução should be designed with compensation capacity according to actual needs, and try to ensure that the monthly average power factor is above 0.95. If necessary, the supplier is required to test on site to improve the accuracy of the design scheme.

2. The reactor of the forno de fusão por indução should be selected as a single-phase filter reactor as much as possible, with low temperature rise and low loss.

3. The induction melting furnace can be designed as a filter branch according to customer needs, such as 5, 7, 11, 13, high pass, C type, etc. The harmonic requirements meet the national standard.

4. Induction melting furnace capacitors should use “single-phase, explosion-proof” capacitors as much as possible.

5. The induction melting furnace is equipped with overvoltage, overcurrent, overload, overtemperature and other related protections.

6. The switching switch adopts vacuum contactor. The load of the forno de fusão por indução is very stable and there is no need to choose the reactive power compensation of the thyristor switching, and the loss of the thyristor is very large. It is recommended to use a vacuum contactor as the control element, which has high reliability and low loss.
