31. Graphite electrodes are rods used in what are known as electric arc furnaces , which help melt scrap steel. 32. It includes a blast furnace, the only one in Peru, and several electric arc furnaces that produce steel sponges. 33. Today, electric arc furnaces ( EAF ) are a common method of reprocessing scrap metal to create new steel. 34. The steel production moved from produced from iron ore with blast furnaces to electric arc furnaces using recycled steel. 35. Hylsamex also will finish adding an electric arc furnace to its plant in the central Mexican state of Puebla. 36. SGL produces graphite electrodes, which are mainly used to conduct electrical current during steel melting operations using arc furnaces . 37. Electric arc furnace steelmaking is the manufacture of steel from scrap or direct reduced iron melted by electric arcs. 38. A typical steelmaking arc furnace is the source of steel for a mini-mill, which may make bars or strip product. 39. Some physical components of the steelmaking process itself, such as the electric arc furnace , may also wear down and oxidize. 40. H�roult's second most important contribution is the first commercially successful electric arc furnace ( EAF ) for steel in 1900.
