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, which is only used by enterprises with a certain scale, and the steel it produces is relatively pure.

intermediate frequency furnace: compared with electric arc furnace, the cost of steelmaking is lower, which is suitable for small and medium-sized enterprises. The steel produced is impure because of many impurities and high carbon content.

2, the electric arc furnace uses power frequency electricity;

the medium frequency electric furnace uses medium frequency electricity.

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

the intermediate frequency furnace has high efficiency and thermal efficiency, thus achieving high production efficiency, flexible operation and low energy consumption.

4. The two methods of heating are different, resulting in different temperatures and different efficiencies.

5, the electric arc furnace uses power frequency electricity.

the intermediate frequency furnace uses intermediate frequency electricity.

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