What are the improvements of the induction melting furnace environment?

What are the improvements of the induction melting furnace environment? – Most modern foundries have a large production capacity, so the power of the electric furnace is also large, which may bring high-order harmonic pollution to the power grid. The degree of harmonic interference of the intermediate frequency solid-state power supply to the power grid mainly depends on whether the harmonics injected into the public connection point of the power grid exceed the standards promulgated by the state. The measures to reduce the suppression of the power supply from injecting harmonic currents into the public connection points of the power grid are as follows:

a) Increase the number of rectified phases of the power supply. This measure can eliminate the 5th, 7th, 17th, and 19th harmonics;

b) Install a resonant filter to filter out the main harmonic currents, such as installing 5th, 7th, and 11th order filters;

c) Change the power supply point and connect the intermediate frequency power supply to the public grid with a large short-circuit capacity.

In addition, the smoke and dust produced by the melting of non-ferrous metals and cast iron under certain process conditions also pollute the environment. At this time, the installation of the exhaust hood is necessary for the improvement of the environment.
