The Complete Book on Ferroalloys: Ferroalloy production
The Complete Book on Ferroalloys (Ferro Manganese, Ferro Molybdenum, Ferro Niobium, Ferro Boron, Ferro Titanium, Ferro Tungsten, Ferro Silicon, Ferro Nickel, Ferro Chrome) An alloy is a mixture or solid solution composed of metals Similarly, Ferroalloys are the mixture of Iron with high proportion of other elements like manganese, aluminium or siliconProducts prone to highly variable releases of process gases are typically not made in covered furnaces for safety reasons As the degree of enclosure increases, less gas is produced for capture by the hood system and the concentration of carbon monoxide in the furnace gas increases124 Ferroalloy Production US EPAIn the process of smelting, huge amounts of electricity is consumed The material is tapped from the furnace intermittently When enough smelted ferrochrome has accumulated in the hearth of the furnace, the tap hole is drilled open and the molten metal and slag are rushed down to Balasore Alloys : Production ProcessAccording to the data published by Indian Ferro Alloys Producers' Association (IFAPA), capacity utilisation of the ferro alloy industry is only 65 percent for the manganese and chrome alloys Both the manganese and chrome alloy manufacturers are starved for the basic raw material the ores In India, there are 133 companies producing ferro alloys in bulk with 252 furnaces Most of the FERROALLOYSFERROMANGANESE, SILICOMANGANESE, Ferroalloys are usually produced by the reduction of a metallic ore (generally oxide) by carbon with the addition of electric energy in a Submerged Arc Furnace (smelting process); or by metals (metallothermic reduction), usually aluminium or silicon High carbon ferromanganese is produced by the reduction of manganese ore by carbon, in electric submergedarc furnaces or in blast furnaces Production processes Association of European ferroAlloy

Ferrosilicon Wikipedia
Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys This prevents the loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, calcium silicides, and many other materials are used for the same purpose It can be used to make other ferroalloys Ferrosilicon is also used for Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si) They are used in the production of steels and alloys The alloys impart distinctive qualities to steel and cast iron or serve important functions during production and are, therefore, closely associated with the iron and steel industry, the Ferroalloy WikipediaThe ferro silicon manufacturing process of those models are same Raw materials: coke, iron ore, silica stone Requirement to raw materials in ferro silicon manufacturing process: Silica stone SiO2 purity above 975% No sand, dust or other impurities on the surface Size ranges between 80140mm Coke with fixed carbon no less than 82%, size 818mm, moisture below 16%, volatile matter below 8% Ferro Silicon Manufacturing Process MethodProduct Safety Information (PIS) is a voluntary presentation of certain information that may assist the user in the handling of Ferrochrome 1 IDENTIFICATION OF SUBSTANCE AND COMPANY 11 Product Identifier Ferrochrome (FeCr) High Carbon Ferrochrome (HCFeCr) Charge Chrome Reach Reference No Chromium 01310009 Iron 01240052 CAS number Ferrochrome 11114 FERROCHROME (FeCr) Vargön AlloysThe process according to the present invention relates to the production of ferrovanadium alloys The process comprises melting a charge containing iron and vanadium with a subsequent reduction of iron and vanadium to give a metal melt In accordance with the present invention, iron and vanadium are reduced substantially completely The resulting metal melt is poured into a converter and then USA Process for producing ferrovanadium alloys
