What's the difference between an electric arc furnace and an intermediate frequency furnace?

1, electric arc furnace: the volume is generally more than 3 tons. Only enterprises with a certain scale can use electric arc furnace, which produces pure steel.

Intermediate frequency furnace: Compared with electric arc furnace, the steelmaking cost is lower and it is suitable for small and medium-sized enterprises. The steel produced is impure, because there are many impurities and high carbon content.

2. The electric arc furnace uses power frequency electricity;

Medium frequency electric furnace uses medium frequency electricity.

3. The electric arc furnace has low thermal efficiency, low productivity, complicated operation and high energy consumption.

Intermediate frequency furnace has high efficiency and high thermal efficiency, thus realizing high production efficiency, flexible operation and low energy consumption.

4. Different heating methods lead to different temperatures and different efficiencies.

5. Electric arc furnace uses power frequency electricity.

Intermediate frequency furnace uses intermediate frequency electricity.

The picture above shows an electric arc furnace, and the picture below shows an intermediate frequency furnace.
