We specially focus on small DC ARC furnace, because it is safe, has high efficiency and low energy consumption, the higher temperature can melt most of metal and nonmetal quickly.
EAF is suitable for adding any material, because the melting material will be rolled together with electric current, the material can be mixed very well.
Whether melting metal or nonmetal, DC ARC furnace will save more energy than AC furnace, because melting material will be rolled up from bottom follow with electric current (Fully Stirred), so the melting speed will be quickly, also it is workable to add any material and adjust the content of chemical element.
EAF also be named Submerged Arc Furnace, because if melt non-conductor product, the firing point will under the material, so the name means that electric arc is submerged in the material.
A three-electrode AC submerged arc furnace is a type of electric arc furnace used in the metallurgical industry to produce high-quality ferroalloys and other metals through a process known as smelting.
The furnace has three graphite electrodes that are inserted into the furnace through the roof, and which are arranged in a triangular configuration. The electrodes are then lowered into the furnace to create an electric arc between them and the metal charge (e.g. scrap, ore, and other materials) in the furnace.
The furnace operates by passing an alternating current (AC) through the electrodes, which creates a high temperature plasma arc that melts the metal charge. The three-electrode design ensures that the plasma arc is evenly distributed throughout the furnace, allowing for efficient melting and smelting of the metal charge.
Submerged arc furnaces are typically used to produce high-quality ferroalloys, such as ferrosilicon, ferromanganese, and ferrochrome, as well as other metals like titanium and magnesium. The use of three electrodes in an AC submerged arc furnace provides several advantages over other types of furnaces, including better temperature control, increased energy efficiency, and improved productivity.
