What are the commonly used types of electric arc furnaces? Many people only have a superficial understanding of electric arc furnaces and do not know what they are=“ http://www.ayynd.com/product/20 Target="_ self">Electric arc furnace, let alone what types of electric arc furnaces there are. Today, let's follow the electric arc furnace manufacturer to learn about the common types of electric arc furnaces! 1. Three phase electric arc furnaceThree phase electric arc furnace is called a three-phase electric arc furnace because it uses three-phase AC power, usually using carbon electrodes or graphite electrodes. An arc occurs between the electrode and the melting furnace material, and the furnace material is directly heated by the arc. The arc length is adjusted by lifting and lowering the electrode. Sometimes, in order to improve the quality of smelting, the bottom of large electric arc furnaces is equipped with electromagnetic stirring, which can drive the melting inside the furnace to rotate at a certain angle, so that the furnace material is heated and the metal liquid is evenly released. Metal circulates in a certain direction. Electric arc furnaces weighing over 50 tons are often equipped with a furnace body rotating mechanism that can rotate left and right. 2. Self consuming electric arc furnaceThe electrode of this electric arc furnace is the raw material of molten steel.. During smelting, as the steel raw materials continue to melt, the electrode descends continuously. Drip molten steel into a copper cylindrical crucible cooled with water and condense it into steel ingots. This furnace is mainly used for smelting alloy electric arc furnace steel. 3. Single phase electric arc furnaceAs the name suggests, an electric arc furnace powered by single-phase AC electricity is called a single-phase electric arc furnace. The furnace charge is indirectly heated by an electric arc. Single phase electric arc furnaces are mainly used for melting copper and copper alloys. 4. Resistance arc furnaceStructural furnace is similar to steelmaking arc furnace.. During operation, the lower end of the electrode is buried in the furnace charge to initiate an arc. The heat generated by the arc between the electrode and the charge, when current passes through the charge, also generates a very, very large amount of heat due to the resistance of the charge. Alright, that concludes the information about electric arc furnaces introduced by the electric arc furnace manufacturer.

What are the factors that affect the service life of electric arc furnaces? Every transaction has a lifespan, usually in order to make our=“ http://www.ayynd.com/product What are the factors that affect the lifespan of electric arc furnaces, as we need to do a lot of work for them to last longer? We can consult with the electric arc furnace manufacturer Youneng De! 1. Influence of high temperature thermal effectSmelting temperature is generally above 1600, which has a significant impact on furnace age. In addition, due to the design of the first and second furnaces, the furnace lining needs to withstand rapid heating and cooling. This phenomenon is inevitable in the smelting process, but it is necessary to minimize or reduce the degree and time of high-temperature heat effects as much as possible, including rapid melting and charging, ensuring the normal operation of equipment, and minimizing downtime to the greatest extent possible. 　　2、 The influence of chemical erosionDuring the steelmaking process, various chemical reactions are constantly occurring, especially at the slag steel interface where they are more intense. The refractory material of the furnace lining is prone to peeling off under the action of chemical reactions. Chemical erosion is related to the composition and flowability of slag. When the content of acidic or slightly acidic oxides such as SiO2, P2O5, Al2O3, or Fe2O3 in the slag is high, MgO is prone to react and form magnesium silicate and magnesium aluminate. The influence of slag fluidity on chemical erosion is mainly due to the low alkalinity of dilute slag, severe chemical reactions, rolling of molten slurry, and easy increase of furnace lining heat load. Thick slag is difficult to heat in the melting pool, requiring an extended high-temperature smelting time to promote damage to the furnace lining. In addition, there are many factors that can affect the lifespan of an electric arc furnace. We will not introduce them one by one here.
