Meta description: With the development of the metallurgical industry, the application of electric arc furnace and submerged arc furnace has been a greater development
Abstract: This article mainly introduces the metallurgical industry in the electric arc furnace and submerged arc furnace difference and the specific nature of the features.
electric arc furnace
Details:
I. Nature:
（1）Electric arc furnace:
Is the use of electrode arc generated by the high temperature melting ore and metal furnace. Through the metal electrode or non-metallic electrode generated arc heating industrial furnace is called an electric arc furnace. Arc furnace can be divided into three-phase arc furnace according to the form of arc, self-consumption arc furnace, single-phase arc furnace and resistance arc furnace and other types. Electric arc steelmaking furnace body by the furnace cover, door, steel groove and body composition, the bottom and walls of the furnace with alkaline refractory materials or acid refractory masonry. Electric arc steelmaking furnace according to each ton of furnace capacity with the transformer capacity of how much is divided into ordinary power arc furnace, high power arc furnace and ultra-high power arc furnace.
（2）Submerged arc furnace:
Also known as electric arc furnace or resistance furnace, is a huge power consumption of industrial electric furnace. It is mainly used for reduction smelting ore, carbonaceous reductant and solvent raw materials, the main production of ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicomanganese alloy ferroalloys, is an important industrial raw materials in the metallurgical industry and calcium carbide and other chemical raw materials.
2.characteristics:
（1）Electric arc furnace:
Its work is characterized by gas discharge to form an electric arc when the energy is very concentrated, the arc temperature above 3000 ℃. Electric arc furnace than other steelmaking furnace process flexibility, can effectively remove sulfur, phosphorus and other impurities, the furnace temperature is easy to control, the equipment covers a small area, suitable for high-quality alloy steel melting. Electric arc furnace steelmaking is through the graphite electrode to the electric arc steelmaking furnace electric energy input, to the electric extremity and charge between the arc as a heat source for steelmaking. Electric arc furnace to electric energy as a heat source, can adjust the furnace atmosphere, the melting of steel containing oxidizable elements more favorable.
（2）Submerged arc furnace:
Its work is characterized by the use of carbon or magnesium refractory materials for the furnace lining, the use of self-cultivated electrodes. Electrode inserted into the charge for submerged arc operation, the use of arc energy and current through the charge, due to the resistance of the charge and generate energy to melt the metal, successive charging, intermittent out of the iron slag, continuous operation of a kind of industrial electric furnace.
This is the introduction of the nature as well as the characteristics of electric arc furnace and submerged arc furnace. If you have any questions or needs for furnaces, please feel free to contact us, Xi’an Hani Tech will provide one-stop service and turnkey project for you.
