High Temperature Melting DC Electric Arc Furnace

Double electrode DC electric arc furnace

100~10000kVA

This DC electric arc furnace can provide ultra-high temperature arcs to process various raw materials that require high-temperature heating. The temperature of the arc core is 10000 ℃, and the peripheral temperature of the arc light is 4000 ℃. Can complete various ultra-high temperature heating tasks. For example, graphite purification, high-temperature ablation testing of workpieces, electrode durability testing, rare earth element melting, etc. The DC electric arc furnace operation process is safe and stable. The DC electric arc furnace is easy to operate and has a high degree of automation. All kinds of protective measures are complete and have no impact or pollution on the power grid. Low noise, no harm to human body.

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.
