Blast FurnaceBlasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace The method used in blast furnaces have been used since the 's.gcse 2 Blast furnace extraction of iron recycling, steelIron ore is used to make iron and steel eg haematite and magnetite Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides

Blast furnace uses iron ore as the iron bearing raw materials, and coke and pulverized coal as reducing agents and heat source, lime, or limestone as the fluxing agents The main objective of blast furnace ironmaking is to produce hot metal with consistent quality for BOF steelmaking process.Blast furnaceA blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper Blast refers to the combustion air being "forced" or supplied above atmospheric pressure In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with.Steps in the Modern Steelmaking ProcessMay 16, &#; Ironmaking, the first step, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace The resulting molten iron also referred to as hot metal still contains 4 45 percent carbon and other impurities that make it brittle.HOW A BLAST FURNACE WORKSHOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal" The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.CHAPTER 11 IRON AND STEEL PRODUCTION FlashcardsStart studying CHAPTER 11 IRON AND STEEL PRODUCTION Learn vocabulary, terms, and more with flashcards, games, and other study tools , Blast furnace Coke, iron ore and limestone are charged (stockpiled) at the top of the furnace , carbon helps to extract more iron by reducing ferric oxide to ferrous oxide from which iron is finally.major steps in process of reducing the iron ore to iron blaststeps in iron ore extraction 1 Introduction to the extraction of metals , Iron ore is used to make iron and steel and iron is produced in a blast furnace by reducing iron oxides with Live Chat; the major steps in the process of iron ore mining.

The Making of Iron & Steel

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue" The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.

Iron Ore Smelting ProcessIron Ore Smelting Process Using Modern Blast Furnac Although the basic ingredients of an iron ore blast furnace has changed little over the last hundred years or so, the furnaces themselves have been modernized to improve efficiency and the purity of the iron and steel.chemistry stuff Extraction of Iron (Fe) from its haematiteSep 13, &#; Extraction of Iron (Fe) from its haematite Iron is extracted by heating the iron ore with carbon in the blast furnace , The process of the extraction of iron from Haematite is carried out in a blast furnace by the following steps 1 Concentration of ore.COREX ProcessCompared with the traditional iron making process via the blast furnace route, the COREX process differs since non coking coal can be directly used for ore reduction and melting work, eliminating the need for coking plants The use of lump ore or pellets also dispenses with the need for sinter plants.FINEX ProcessFINEX Process is a fluidized bed based process using ore fines instead using iron ore lumps and pellets This is a process with great potential with regard to productivity and the low cost production of hot metal In , POSCO and VAI, Austria signed an agreement to work together for a joint development of the FINEX Process.process of making iron from oreThe first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent , The extraction of metals and its isolation occurs over a few major steps , Although the basic ingredients of an iron ore blast furnace has changed little over the.Creating SteelAnother way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converterThe heat of oxidation raises the temperature and keeps the iron molten As the air passes through the molten pig iron, impurities unite with the oxygen to form oxid.Iron and Steel ManufacturingIron and Steel Manufacturing Industry Description and Practices Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufac turing process or a direct reduction process In the conventional integrated steel manufacturing process, the iron from the blast furnace is con verted to steel in a basic oxygen furnace.

Process Fans in Iron and Steel Industry

Nov 29, &#; Sinter Plant Fans The process of sintering is basically a pre treatment process step during iron making to produce charge material called sinter for the blast furnace from iron ore.

How is steel produced?Feb 16, &#; Steel is an alloy of iron and carbon So the primary raw materials we require are iron ore and coal This iron ore along with metallurgical coke produced from coke oven are fed as raw material into the blast furnace where by reduction process we m.The HBI direct reduction processNov 03, &#; The direct reduction process HBI is the product of reducing iron ore with natural gas This is called the direct reduction process and is an environmentally friendly production process; a DRI plant uses natural gas which is more environmentally sound than coke The reduction process takes place in the reduction tower.Iron and SteelmakingA blast furnace charge consists of ore, fluxes and fuel The ore part of a charge consists of iron ores and concentrates, manganese ores and various types of scrap containing iron These ore parts are usually contained in a charge as products of a high temperature treatment ie as agglomerate or pellets Agglomerate currently.How is iron formed or made?Jun 26, &#; Iron is formed in a large variety of ways Most of the iron we see however, is formed from fusion within stars Stars produce heat and light due to nuclear fusion process The immense gravity from stars causes the elements that make up the star.IRON AND STEELThis page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke.
