Electric arc furnaces are mainly used for steel smelting, ferroalloy refining, titanium, zirconium, molybdenum and other difficult metals.
What is produced in an electric arc furnace?
There are many types of arc furnace, which are divided into several types according to power source, furnace material, loading furnace burden and power.
AC electric arc furnace
The arc furnace USES alternating current as the power source, and generally USES graphite electrode. The arc occurs between the electrode and the smelted charge, which is directly heated by the arc. The arc length is adjusted by lifting electrodes. In order to improve the smelting quality, the large electric arc furnace in the bottom with an electromagnetic stirrer, drive the furnace to melt the Rong metal circulation along a certain direction.
DC electric arc furnace
It is an electric arc furnace using direct current as energy source. Like the AC arc furnace, it USES the arc generated between the electrode and the charge (or molten pool) to generate heat and thus achieve the purpose of smelting. Can be used to melt steel or alloy and non-ferrous metals.
