At these mills‚ liquefaction of the metallic charge is carried out in electric arc furnaces with electricity as the main energy source. Since scrap iron already contains carbon‚ there is no need to add carbon by using coal or coke‚ eliminating the need for

pulling the trigger‚ eh? Tell me this then - what types of welding are there? Not completely sure? Read on... Arc Welding Arc welding is a process utilizing the concentrated heat of an electric arc to join metal by fusion of the parent metal and the addition of metal to joint usually provided by a consumable electrode. Either direct or alternating current may be used for the arc‚ depending upon the material to be welded and the electrode used. Electroslag Welding Electroslag Welding (ESW)

welding that forms an electric arc between the metal and a wire electrode. The electric arc between the metal and the electrode melts the metal and allows it to be joined. An inert gas shield travels through the welding gun‚ which serves as protectant from outside air contaminating the process. This process generally requires a direct current power supply‚ but sometimes alternating current power systems are used. Electrodes are wires that allow an electric arc to form between it and a metal

Do I Compare Electric Arc Furnaces and Blast Furnaces? How Do I Compare Electric Arc Furnaces and Blast Furnaces? By Helen Akers‚ eHow Contributor Electric arc and blast furnaces create high temperatures to turn metals into liquid form. Both blast and electric arc furnaces are used in industrial settings to heat and mold metal. A blast furnace is used to make steel from liquid iron‚ while an electric arc furnace is used to make steel from scrap material. Electric arc furnaces use two different
