Application Introduction of Intermediate Frequency Melting Furnace

An induction melting furnace is a type of equipment that uses electromagnetic induction to melt metal. There are different types of induction melting furnaces, including medium frequency melting furnaces and intermediate frequency melting furnaces. In this article, we will focus on the application introduction of intermediate frequency melting furnaces.

Intermediate frequency melting furnaces are widely used in the metal casting industry, particularly for melting non-ferrous metals such as copper, aluminum, and their alloys. They are also used for melting ferrous metals, such as steel and iron. The advantage of intermediate frequency melting furnaces is that they can achieve high melting rates and are more energy-efficient than other types of furnaces.

The working principle of an intermediate frequency melting furnace is based on the electromagnetic induction principle. A coil of copper tubing is wrapped around the furnace chamber, and an alternating current is passed through the coil, creating a magnetic field that induces eddy currents in the metal being melted. The eddy currents generate heat, which melts the metal.

One of the main advantages of intermediate frequency melting furnaces is that they can achieve high melting rates. The melting rate depends on the power of the furnace, the size of the furnace, and the material being melted. For example, a 500 kW intermediate frequency melting furnace can melt 500 kg of aluminum in just 10 minutes.

Another advantage of intermediate frequency melting furnaces is their energy efficiency. Compared to other types of furnaces, such as gas-fired furnaces, intermediate frequency melting furnaces use less energy to melt the same amount of metal. This is because the heat is generated directly in the metal being melted, rather than being transferred from a flame or hot gases.

In conclusion, intermediate frequency melting furnaces are widely used in the metal casting industry for melting non-ferrous and ferrous metals. They offer high melting rates and are more energy-efficient than other types of furnaces. If you are in the market for a melting furnace, consider an intermediate frequency melting furnace for your operation.
