An electric furnace called an induction furnace heats and melts metals using electromagnetic induction. Metals like iron, steel, and copper, among others, are melted using it frequently in the foundry sector of the economy. The operation of an induction furnace and its advantages over other types of furnaces will be covered in this article.
How does an induction furnace work?
The electromagnetic induction theory underlies the operation of an induction furnace. A magnetic field will be generated all around a coil when a current of alternating nature flows through it. The coil, which is made of refractory material, is filled with the melted metal. When the magnetic field surrounding the coil interacts with it, eddy currents are produced in the metal. As a result, the metal heats up and finally be melted.
The coil receives the alternating current from the furnace’s electric power source. The type and weight of the metal determine the amount of power needed to melt it. Altering the alternating current’s strength and frequency makes controlling the furnace simple.
Advantages of an induction furnace
using an induction furnace has many advantages over using other types of furnaces. One of its primary advantages is its outstanding energy efficiency, which frequently requires 30 to 50 percent less electricity than other types of furnaces. This happens so that the heat is generated by the metal itself rather than by the furnace’s walls or its surroundings.
The ability of induction furnaces to melt metals quickly—often in under an hour—is another benefit. They are therefore perfect for usage in foundries where rapid melting is necessary. Because they may be used to melt both ferrous and non-ferrous metals, induction furnaces are also particularly adaptable.
Conclusion
Induction furnaces are a very effective and adaptable form of furnace that are commonly utilized in the foundry sector, in conclusion. It is a preferred option for foundries all over the world due to its capacity to swiftly melt metals and efficiency in terms of energy use. A wide variety of induction furnaces are available from FUTURE, a reputable producer of crucibles and energy-efficient electric furnaces, and they are ideal for foundries of all sizes.
