  • What is the purpose of limestone in a blast furnace quora

    Iron ores are usually purchased as fines or as pellets consisting mostly of iron oxide. iron ore pellets are fed directly into the blast-furnace. iron ore fines are mixed at the ironworks with limestone and other minerals and pre-fired at low temperatures to form a sinter, i.e. agglomerates that can then be fed to the blast-furnace. finely divided quicklime is often added to the sinter mixture to assist in binding the material to improve productivity and give a stronger sinter structure.

  • Limestone its processing and application in iron and

    The process of iron making is the reduction of iron oxide to iron. most of the worlds iron is made in blast-furnaces, which produce liquid iron. iron oxides normally occur as iron ores which also contain quantities of impurities particularly silica. thus, the commercial iron making process involves the removal of these impurities, usually by forming a slag with quicklime.

  • Gcse chemistry extraction of iron in the blast furnace

    Quicklime cao is formed during iron making from added limestone caco3. the heat in the blast-furnace decomposes the limestone to quicklime which then reacts with the impurities and produces the slag. blast-furnace slag is a useful by-product used widely in the construction industry.

  • Pig iron furnaces abandoned building photography

    Iron from the blast-furnace often contains excessive levels of sulfur. as desulfurisation in the steelmaking process is not compatible with other purification processes, it is often carried out externally to the rest of the process. a simple treatment involves injection of fine quicklime and other minerals into the transfer ladle which moves iron from the blast-furnace to the steelmaking vessel. the slag, containing much of the sulfur from the iron, is removed before the hot metal is conveyed to the steelmaking vessel.

    In bos, a vessel, lined with magnesia-based refractories, is charged with molten iron, often with the addition of scrap, iron ore, or waste iron oxide briquettes as supplementary iron and steel sources. carbon is removed from the melt by injecting oxygen at high speed, which oxidises some of the iron and many of the impurities present e.g. silica and phosphorous.
