Ferro 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 in the deoxidation of the casting, although you can find alloy elements such as Boron, Cobalt, Niobium, Molybdenum, Nickel, Phosphorus, Titanium, Tungsten, Vanadium, Zirconium, Magnesium, Calcium, etc ferro alloy is composed of at least 73% silicon and 24% of Iron, which has its main application in the treatment of iron base. For the manufacture of Ferro, alloying is used as the mineral quartz, its quality is a function of aluminum content is, the process begins with the screening, cleaning dust and dirt that comes with it, classifying then according to particle size which can identify two alternatives: the coarse-grained to be used in the actual casting and the fine to cover the mouths of the same, made this classification is loaded raw materials consist mainly of limestone, iron ore, coal and quartz in the furnace of carbon electrodes, (this is not the only kind of oven used for this purpose is the most common), it is important that other elements must also be properly classified in particular where discarded coal sizes fine, the same that are desechandoos in what is called carbon. The furnace charge is a delicate process that takes place with the help of special vehicles usually powered by electricity, the operators of these (picks) should be especially careful not to hurt the electrodes of the furnace when carbon (graphite electrode ) are very fragile and whose replacement can significantly delay the production is also common to find vehicles scum removers spoons equipped with hydraulically commanded With the aid of heat the coal reacts with metal oxides formed carbon monoxide and iron silicate FeSi, the process aims to reduce the base metal minerals. Ferro is then removed with the aid of utensils, specially designed for this purpose, then you add magnesium scrap and other additives, then reheat it to the temperature of the homogenized casting foundry, at this point occurs a reaction with a significant evolution of heat and light, this identifies the formation of Ferrosiliciomanganesio, what follows is the casting ingot. Then the ingot is ground obtained with the help of jaw crushers known as "primary" and later give the refinement with a cone crusher which is called "secondary." The Ferro Manganese obtained has a wide variety of sizes and therefore requires a classification being usual one that go from 0 to 100 mL, marketing usually takes place in 1200 kg bags
