What kinds of electric arc furnaces are commonly used?


1. Three phase electric arc furnace


Three phase electric arc furnace is called three-phase electric arc furnace because it adopts three-phase alternating current. Carbon electrode or graphite electrode is usually used. The arc occurs between the electrode and the smelting charge. At this time, the charge will be directly heated by the arc, and the arc length can be adjusted by the rise and fall of the electrode. Sometimes, in order to improve the quality of smelting, electromagnetic stirring is installed at the bottom of large electric arc furnace, which can drive the melting in the furnace to a certain angle, so that the furnace charge is heated and the molten metal is discharged evenly. Metal circulates in a certain direction. Electric arc furnaces with more than 50 tons are often equipped with furnace body rotating mechanism, which can rotate left and right.


2. Consumable electric arc furnace


The electrode of this electric arc furnace is the raw material of molten steel. During smelting, with the continuous melting of steel raw materials, the electrode decreases continuously. Drop the molten steel into the red copper cylindrical crucible cooled with water and condense it into steel ingot. The furnace is mainly used for smelting alloy electric arc furnace steel.


3. Single phase electric arc furnace


As the name suggests, the electric arc furnace powered by single-phase AC is called single-phase electric arc furnace. The charge is heated indirectly by electric arc. Single phase electric arc furnace is mainly used for smelting copper and copper alloys.


4. Resistance Arc Furnace


Structural furnace is similar to steel-making electric arc furnace. During operation, the lower end of the electrode is buried in the furnace charge for arcing. The heat generated by the arc between the electrode and the charge. When the current passes through the charge, the resistance of the charge will also produce a very, very large heat.


Electric arc furnace is mainly used to smelt ore, so it is also called submerged arc furnace in many places. Well, to sum up, it is about the type analysis of electric arc furnace. If you have any doubts, please pay attention to our official website: http://www.ayynd.com/
