Ferromanganese broadly known as ferro-alloys Iron alloys to that more coal than have another element, which are often useful as agents that react to improve the properties of steel. The principal ferroalloys are those of chromium, silicon and manganese, which provide respectively: corrosion resistance, counteract the effects of sulfur, and collaborate in the deoxidation of the cast, although you can find alloy elements such as boron, cobalt, niobium , Molybdenum, Nickel, Phosphorus, Titanium, Tungsten, Vanadium, Zirconium, Magnesium, Calcium, etc. The Ferromanganese is used in the production of virtually all kinds of steel and cast iron production, Ferro-Alloy Steel normally is added to remove nitrogen bubbles and reduce the iron oxide formed during processing. Steel is hard won, you can identify the following ferromanganese: Ferro-silico-manganese, silico-manganese used in the production of fine grade steel, medium carbon Ferro Nitrogen useful in the automotive industry, Low Carbon Ferro Alloys is a refined very ductile, which provides machinability to Steel, Ferro-half coal and high carbon Ferro special application. The process begins with the classification of the raw material storage silos and then this material is transported to the furnace with the aid of special vehicles usually powered by electricity, the operators of these (picks) should take special care not to hurt electrodes of the furnace when carbon (graphite) are very fragile and whose replacement can significantly delay the production is also common to find vehicles equipped with scum removers hydraulically commanded spoons. The oven can be very different geometry and type can be identified among the main submerged electric arc furnaces and electrolytic cell the first being the most common. The arc furnace submerged electric can be classified into two types of open and closed, the first appear to be widespread, and are basically a melting pot where you place the elements to melt, then introduce the respective electrodes, usually three, resulting in using these, a electric arc that achieves the transformation of alternating electrical energy into heat, reaching temperatures of around 1300-2000 C the same as are required to melt the raw material, such furnaces are equipped with a bell on top that queue the fumes generated, which are taken to the house of smoke, whose function is to reduce the pollution generated by the "capture" of the particles in suspension and cooling of the gases released, to achieve this effect is usually precipitation lines and high-capacity filters These ovens are covered with refractory material and its consumption is the order of several megawatts for which are usually equipped with their own generation plants or properly sized substations. Today the main producers of Ferro are China, South Africa and Ukraine, although in South America can also identify major productions in countries such as Brazil and Argentina.
