  • 1A Manufacturing Process for Iron and Steel

    The smelting and refining process for iron and steel in the BFBOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas(CO) generated by the oxidation of the carbon(C) in coke. Consequently, carburization .

  • Sintering: A Step Between Mining Iron Ore and Steelmaking

     · World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

  • Steelmaking

    With the ironore based route, hot metal is mostly produced from iron oxide ores in blast furnaces, and more rarely in smelting reduction plants, and is processed to make crude steel in oxygen converters. Sponge iron (direct reduced iron, DRI; hot briquetted iron, HBI) produced from iron ore in direct reduction plants is converted to crude steel in electric arc furnaces. .

     · Iron Ore Formation. Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times highgrade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration. Iron formation is .

    Iron ore and metallurgical coal are used mainly in the blast furnace process of ironmaking. For this process, coking coal is turned into coke, an almost pure form of carbon, which is used as the main fuel and reductant in a blast furnace. Typically, it takes tonnes of iron ore and around 450kg of coke to produce a tonne of pig iron, the raw iron that comes out of a blast furnace. .
