Limestone – Its Processing and Application in Iron and
Application of limestone and lime in iron and steel plant During the production of iron by blast furnace (BF) route, limestone is added either in the process of sintering or as a direct feed in the blast furnace Limestone is normally added during ironmaking 2 天前 iron processing: The blast furnace Basically, the blast furnace is a countercurrent heat and oxygen exchanger in which rising combustion gas loses most of its heat on the 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 limestoneBlast furnace metallurgy Britannicablast furnace (metallurgy) Encyclopedia Britannica Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metalsThe furnace charge, or burden, of ironbearing materials (eg, ironore pellets and sinter), coke, and flux (eg, limestone) limestone used in blast furnace

MF 1855 BF Slag as an Agricultural Liming Material
Agricultural Slag Comes From Limestone and Dolomite Agricultural slag, or AgSlag, is a finescreened material from the processing of iron blastfurnace slag, a byproduct of the iron and steel industry The slag can be watercooled, granulated, or aircooled Chemically, blastfurnace slag is pellets, and sinter in blast furnaces with subsequent refining of molten iron and scrap in oxygenblown processes The electric furnace is used to make steel, stainless steels, ferroalloys, and special alloys, whereas ferromanganese is often made in blast fur naces Fluxes are used in all of these processes, and either limestoneMETALLURGICAL USES FLUXES FOR METALLURGY 7 The limestone in the furnace charge is used as an additional source of carbon monoxide and as a “flux” to combine with the infusible silica present in the ore to form fusible calcium silicate Calcium silicate plus other impurities form a slag that floats on top of the molten metal at the bottom of the furnaceBASIC OXYGEN STEELMAKING (BOS) The Processing
