What are the common types of electric arc furnaces? We have talked about many types of electric arc furnaces before. So, what are the common types of electric arc furnaces? Let's learn about it together!

　　 Three phase electric arc furnace

This type of electric arc furnace uses three-phase AC power as the switching power supply, and generally uses carbon electrodes or high-purity graphite electrodes. The arc is generated between the electrode and the melted furnace material, and the furnace material is immediately heated by the arc. The length of the arc is adjusted by adjusting the electrode. To improve the quality of melting, large and medium-sized electric arc furnaces are equipped with electromagnetic stirrers at the bottom of the furnace, forcing the molten metal material in the furnace to circulate in a certain direction. Electric arc furnaces weighing over 50 tons are often equipped with furnace wall rotating structures, which can rotate up and down a certain angle of view, making the furnace material evenly heated. When the metal material liquid is discharged from the furnace, the furnace wall can tilt. Three phase electric arc furnaces are widely used for ironmaking.

Self consuming electric arc furnace

The electrodes of this type of electric arc furnace are the raw materials for the melted steel.

. During melting, as the steel raw material continues to melt, the electrode continues to lower. The melted steel droplets enter the red copper cylindrical clamp pot with cooling water and solidify into cast steel parts. This type of furnace is suitable for melting carbon steel. The self consuming arc furnace used for melting active metals such as titanium, zirconium, tungsten, molybdenum, tantalum, niobium, and silicide metal materials is generally operated under a vacuum pump, hence it is called a vacuum pump self consuming arc furnace.

Single phase electric arc furnace

This type of electric arc furnace uses single-phase asynchronous motors for power distribution.

. The furnace charge is indirectly heated by the arc. Single phase electric arc furnaces are commonly used for melting copper and alloy copper.

Resistive arc furnace

The furnace structure is similar to that of ironmaking arc furnace.

. During work, an arc is generated beneath the electrode buried in the furnace material. In addition to the heat generated by the arc between the electrode and the furnace material, the current generated by the furnace material resistor also causes a significant amount of heat. This type of electric arc furnace is suitable for iron ore smelting plants and is therefore also known as a submerged arc furnace.
