IRON ORE AND STEEL PRODUCTION YouTube. Aug 24, 2016· Iron ore and steel production The 6minute video explains the mining and processing of iron ore, followed by its conversion to steel The links below will, Online Chat Development of Heat Recovery System from Steelmaking Slag
Iron and steel scrap may be added in small amounts. Near the bot tom of the furnace, preheated air is blown in. Coke is combusted i n the furnace to produce carbon monoxide which reduces the iron ore to iron. Silica and alumina in the ore and coke ash are fluxed with limestone to form a slag that absorbs much of the sulfur from the charge. Read
201198&ensp·&enspBlast furnace slag is a combination of silica and other nonferrous components of iron ore, ash from coke used as a reducing material, and limestone auxiliary material. Because its specific gravity is less than that of pig iron, during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered.
2020515&ensp·&enspThe ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being
202057&ensp·&enspIron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron and steelmaking processes.
2015417&ensp·&enspThe effects of use of various products of the slagprocessing plant at Kardemir integrated iron and steel works as blast furnace charge material and as scrap for the converters are given in this study together with the effect of slag addition into sinter mix on the

• sintering and pelletisation of iron ore • the production of molten iron by the blast furnace route, including slag processing • the production and refining of steel using the basic oxygen process, including upstream ladle desulphurisation, downstream ladle metallurgy and slag processing
Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. Iron ore mining is classified into two egories manual mining and mechanized mining methods. Haematite and magnetite are the most commonly found iron ore minerals. Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the
2020511&ensp·&enspThe iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed. The physical characteristics such as density, porosity, and particle size, are affected by the cooling rates and chemical composition.
20181111&ensp·&enspSintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
