Electric Arc Furnace (EAF) [SubsTech]
31/5/2012· Two kinds of electric current may be used in Electric Arc Furnaces: direct (DC) and alternating (AC). Three-phase AC Electric Arc Furnaces with graphite electrodes are commonly used in steel making. The main advantage of the Electric Arc Furnaces over the Basic Oxygen Furnaces (BOF) is their capability to treat charges containing up to 100% of scrap.

Steel making today and tomorrow - Hybrit
In the HYBRIT- concept, specially developed iron ore pellets are reduced by hydrogen gas in a so-called direct reduction process. Reduction occurs in a solid state at a lower temperature than in the blast furnace process and produces an intermediate product, sponge iron or direct reduced iron (DRI), with water vapour emitted from the top of the furnace.
Creating Iron | HowStuffWorks
Pig iron contains 4 to 5 percent carbon and is so hard and brittle that it''s almost useless. If you want to do anything with it, you have three options. First, you can melt it, mix it with slag and hammer it out to eliminate most of the carbon (down to 0.3 percent) and create strong, malleable wrought iron.

15/9/2019· Open-hearth process (also called the regenerative open hearth): A bit like a giant fireplace in which pig iron, scrap steel, and iron ore are burned with limestone until they fuse together. More pig iron is added, the unwanted carbon coines with oxygen, the impurities are removed as slag and the iron turns to molten steel.
Electric Arc Furnace – steeluniversity
Electric Arc Furnaces (EAFs) are used to produce carbon steels and alloy steels primarily by recycling ferrous scrap. In an EAF, scrap and/or manufactured iron– such as DRI, pig iron, iron carbide – units are melted and converted into high quality steel by using high-power electric arcs formed between a hode and one (for DC) or three (for AC) anodes.
