5. Conclusion

The high reliability of power electronic components, the stability of electricity costs and the increasing environmental constraints of the 90s have definitively steered investment towards electric induction melting.

Today, in most foundries, the electric induction furnace has made it possible to replace melting equipment such as cupola furnaces, particularly in the case of ferrous alloys, thereby modernizing foundries for cast iron and non-ferrous alloys.

In a modern foundry, for example, the melting sector occupies half the surface area it did 20 years ago, and its rejects have been divided by three.

The use of medium-frequency induction furnaces now makes it possible to increase hourly output while reducing furnace size. This latter aspect significantly reduces electrical energy consumption per ton of molten metal....
