Ferroalloy refining furnace is mainly used for desiliconization and refining of ore, high silicon low carbon iron alloy refining products and flux, so as to obtain medium carbon, low carbon and micro carbon ferroalloy products, which are generally arc smelting furnaces; , medium chromium, low chromium, low micro chromium, nickel iron, manganese iron, high titanium slag, rare earth alloy, smelting of ferroalloy products such as zirconium.
Equipment consisits :
Furnace roof, furnace shell, electrode lifting system, water-cooled cable, copper busbar system, hydraulic system, H.V, L.V system etc.
1. The products are smelted by the arc thermal while the larger current is passing the electrode. The material of electrode is graphite.
2. The electrode is up above the furnace burden while smelting, the consumption of electrode is lower than submerged arc furnace, so this kind of furnace can be used for smelting low-carbon products.
3. When it was tapping , the furnace can be tilted with the convenience that pouring out the liquid smelted. By the different weight, liquid and slag can be separated in different ladles.
4. This kind of furnace is safe and reliable, is easy to operation. The worker can operate it on computer while charging , smelting, and tapping with HMI.
