What are the common of electric arc furnace?


快盈11vWe have talked a lot about electric arc furnaces before. There are many kinds of electric arc furnaces. What are the common electric arc furnaces? Let's have a look!

Three phase electric arc furnace


This kind of electric arc furnace uses three-phase alternating current as switching power supply, and generally uses carbon electrode or high-purity graphite electrode. The arc is generated between the electrode and the melted charge, and the charge is heated immediately by the arc. The arc length is adjusted by the electrode. In order to improve the smelting quality, large and medium-sized electric arc furnaces are equipped with electromagnetic agitators at the bottom of the furnace to force the molten metal materials in the furnace to circulate along a certain direction. Electric arc furnaces with more than 50 tons are often equipped with furnace wall rotation organization. The furnace wall can rotate up and down with a certain angle of view, so that the furnace charge is symmetrical in case of heat, and the furnace wall can be skewed when the metal material liquid is discharged from the furnace. Three phase electric arc furnace is generally suitable for ironmaking.


Consumable electric arc furnace


The electrode of this kind of electric arc furnace is the raw material of melted steel. During melting, with the continuous melting of steel raw materials, the electrode continues to decrease. The molten steel drops into the red copper cylindrical pliers pot with cooling water and solidifies into steel castings. This kind of furnace is suitable for melting carbon steel. The consumable arc furnace used to smelt titanium, zirconium, tungsten, molybdenum, tantalum, niobium and other active metals and silicide metal materials is generally working under vacuum pump, so it is called vacuum pump consumable arc furnace.


Single phase electric arc furnace


This kind of electric arc furnace uses single-phase asynchronous motor for power distribution. The charge is heated indirectly in the arc. Single phase electric arc furnace is mostly used for smelting copper and alloy copper.


Resistor arc furnace


The structure of furnace is similar to that of electric arc furnace. When working, the arc is buried under the electrode in the charge. In addition to the heat transmitted by the arc between the electrode and the charge, the current also causes a very large heating amount according to the charge resistor. This kind of electric arc furnace is suitable for iron ore smelters, so it is also called submerged arc furnace.
