Double electrode DC Electric Arc Furnace
500~20000kVA
Rare earth is an emerging strategic resource that plays an important role in multiple fields, especially in the semiconductor and military industries.
Due to the difficulty in reducing rare earth elements, slag with higher rare earth content can be obtained when smelting ores containing rare earth elements using pyrometallurgical methods. At present, the smelting of rare earth ferroalloys mainly uses slag with high rare earth content.
The smelting equipment is a DC electric Arc Furnace, which adopts an intermittent operation method. The flux is lime and the reducing agent is 75 # silicon iron alloy, which reduces the rare earth elements in the rare earth slag to obtain rare earth iron alloy.
The smelting process is different from the smelting of other types of ferroalloys. As a reducing agent, ferrosilicon is added to the furnace only after the rare earth slag and lime are completely melted, and stirring is also required to promote the contact between the reducing agent and the slag.
Green and energy-saving, stable and reliable
Equipment characteristics
1.The power consumption is 10%~15% less than that of AC furnace.
2.The consumption of graphite electrode is 40% less than that of AC furnace.
3.Compared with AC furnace, it eliminates the investment of reactive power compensation device.
4.The noise level is 10~20 dB lower than AC furnace.
5.In the smelting process, metal ions in the melt will be concentrated around the negative electrode due to electrolysis, so as to improve the yield and purity of products, which is more conducive to the enrichment of precious metals and other high-value metals.
6.The current direction and electromagnetic field direction of DC furnace remain unchanged. Driven by the magnetic field, the molten slurry circulates in one direction all the time, forming electromagnetic stirring, so that the material melts without dead corners, the product quality is high, and the yield is high.
7.When an accident occurs in the smelting process and a power failure occurs for a period of time, an insulating hard shell will be formed on the surface of the molten liquid.
Facing this situation, the double electrode DC furnace can start arc smelting again by adding arc striking materials such as coke at the bottom of the electrode.
