The EAF used for the production of WFA consists of a refractory-lined steel shell that is equipped with electrodes. The raw materials are loaded into the furnace, and an electric current is passed through the electrodes, creating an arc that melts the raw materials. The melted materials are then cooled and solidified to form white fused alumina.
The production of WFA is a highly energy-intensive process, and the choice of furnace can have a significant impact on the overall efficiency and cost of production. Therefore, the design and operation of the melting furnace are critical for the production of high-quality WFA.
In summary, white fused alumina is produced in electric arc furnaces by melting high-purity alumina and petroleum coke at temperatures of around 2000-2200°C. The furnace design and operation are crucial for the production of high-quality WFA.
Submerged ARC Furnace (SAF) is used for melting alloy and other nonconductive material, because the electric ARC will be happened below raw material, it means electric ARC is submerged under the material, so it is called Submerged ARC Furnace (SAF).
This furnace can be used for producing Ferrosilicon, Silicon iron, Silicoferrite, Ferrosilicium, Si-Al-Calcium Barium Ferroalloy, Silicon-Aluminium-Calcium-Barium-Ferrous alloy, Ferromanganese, Manganeisen, Manganese iron, Ferrochrome, Ferrochromium, low carbon Ferro-chromium and Ferro magnesium.
We can produce DC Electric ARC furnace (EAF), AC Electric ARC furnace (EAF) and Submerged ARC furnace (SAF), this will base on customer’s raw material, producing capacity, and products, if you want to melt steel, scrap iron powder, Silicon, Ferro-silicon, Ferro-chrome, Ferro-manganese, Ferro-tungsten and other alloys, please feel free to inquire us the details.
