The iron and steel sector is the secondlargest industrial user of energy consuming 616 Mtoe in 2007 and is also the largest industrial source of CO2 emissions The five most important producers – China Japan the United States the European Union and Russia – account for over 70 of total world steel production Coke dry quenching appears as the most valid system to reduce air pollutionMore Details
Combustion process The iron in the processed ores must be dissolved out by chemical processes This requires an element that binds oxygen more strongly than iron This is exactly what carbon can do as a reducing carbon is fed to the blast furnace in the form of coke pyrolyzed coal from the coking sufficiently high temperatures the carbon can participate directly in theMore Details
Mining Iron Ore Mining iron ore begins at ground level Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth Taconite rock comprises about 28 percent iron the rest is sand or silica These samples are analyzed and categorized so that mining engineers can accurately develop a mine planMore Details
Broadly speaking suitable blends can be obtained by mixing highvolatile with lowvolatile coals and often small additions of ground small coke and anthracite are helpful Drying the coal and even preheating it to 200 °C 390 °F may also be helpful and economicMore Details
The material remaining is called coke Most metallurgical coke is used in iron and steel industry processes such as blast furnaces sinter plants and foundries to reduce iron ore to iron Over 90 percent of the total metallurgical coke production is dedicated to blast furnace operationsMore Details
“The primary aim of the FINMET development was to improve the energy efficiency of FIOR by ore preheating using top gas and CO 2 removal from reformed gas as well as recycle gas” Laboratory and pilot testing was conducted in 1993–1995 and plants in Australia and Venezuela were under construction in 1999 52 63The Australian plant operated for several years but shut down in 2005 dueMore Details
Blast furnaces produce pig iron from iron ore by the reducing action of carbon supplied as coke at a high temperature in the presence of a fluxing agent such as king blast furnaces consist of several zones a crucibleshaped hearth at the bottom of the furnace an intermediate zone called a bosh between the hearth and the stack a vertical shaft the stack that extends fromMore Details
Mar 09 2013 · Sintering is a thermal process carried out at 1300 deg C to 1400 deg C by which a mixture of iron ore return fines recycled products of the steel plant industry such as mill scale blast furnace dusts etc slag forming elements fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered productMore Details
