Induction Furnace

Electric arc furnace is an electric furnace that uses the high temperature produced by electrode arc to melt ores and metals. When gas discharge forms an arc, the energy is very concentrated, and the temperature of the arc zone is above 3000 ℃ C. For metal smelting, electric arc furnaces have greater flexibility in the process compared to other types of furnaces in steel making, effectively removing impurities such as sulfur and phosphorus. The furnace temperature is easy to control, and the equipment occupies a small area, making them suitable for the melting of high-quality alloy steel.

Different volume size and steelmaking purity

• Electric arc furnace: It is a large volume, usually weighing over 3 tons, and is only used by enterprises with a certain scale. The steel it produces is relatively pure.

• Medium frequency furnace: Compared to electric arc furnaces, steelmaking has a lower cost and is suitable for use by small and medium-sized enterprises. The steel produced is high in impurities and carbon content, so the steel produced is impure.

The electricity used is different

• The electric arc furnace China-type uses power frequency electricity.

• The medium frequency electric furnace uses medium frequency electricity.

Differences in thermal efficiency and productivity

• Electric arc furnaces have 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.

Heating method

• The heating methods of the two are different, resulting in different temperatures and efficiency.
