Dolomite in Furnaces Dolomite is a dry carbonate mineral which is made of calcium magnesium carbonate or CaMg(CO3)2. The rock type of dolomite is called dolostone. Dolomite is closely related to another mineral called huntite. Dolomite plays an important role in the iron and steel industry. It is used in blast furnaces in the industry.
coal furnace manufacturers used in mine for . use of limestone and dolomite in iron ore Mining. nbsp 0183 32 Agglomeration of Iron Ore Iron Ore Plant The purpose of agglomerating iron ore is to improve the permeability of blast furnace . are commonly produced used in the industry namely Sinter and Pellet . iron ore normally 3mm mixed with coke breeze mm limestone dolomite .
Dolomite uses britannicaolomite uses dolomite is used as a source of magnesium metal and of magnesia mgo, which is a constituent of refractory bricks dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces the use of dolostone as a flux has increased, especially.
Sintered dolomite is used in steel making for the production of tar dolomite bricks, pitch impregnated dolomite bricks or resin bonded dolomite bricks for the lining of BOF vessel, AOD (argon oxygen decarburization) vessel, and to a lesser extent electric arc furnace.
Dead burned dolomite used as refractory lining in basic open hearth furnaces and Bessemer converters. Used as basic flux in smelting of iron ore in blast furnace removes alumina and slag. Dolomite provides soil conditioner and used as an accelerator in vulcanizing process and as in decorative building material and polish.
Burnt dolomite is also used for making refractory bricks for the purpose of lining in steel melting shop. Flue gas treatment. During combustion of coal and petroleum products there is high level of SO2 emissions. To control these emissions within norms it becomes necessary to treat the flue gases for SO2 and other acid gases.
Dolomite refractories are also used in electrical furnaces and in cement industry during clinker manufacture. Application. Dolomite is chiefly used as refractory, ramming, and fettling material in steel melting shop, and as fluxing material in blast furnace operation in secondary steel and
Lizenithne used in blast furnace use dolomite blast furnaces were used in china as early as 200 bc products yoshizawa lime industry co. furnace slagmaterial description origin in the production of iron iron ore iron scrap and fluxes lizenithne andor dolomite are charged into a
Limestone amp; Dolomite Its use in furnaces in different countries and continents, allows the refining and manufacture of steel, as well as protecting the refractory lining of furnaces and converters. Calcinor also has specific products for this sector, for example REFRA DOL #174;, designed for use in refractory gunning applications as it is a sintered dolomite with high resistance to hydration.
Since dolomite is a source of both of these minerals, dont use it if you have serious kidney problems. Sarcoidosis : This condition increases the risk of absorbing too much calcium.
The specifications of dolomite for use in ferromanganese are more or less similar to SMS grade dolomite. Physically dolomite should be hard and fine grained because crystalline dolomite gives fritting effect in the furnace. Ferro alloy industry actually consumes dolomite with MgO 19 to 20%, CaO 28 to 30% Si02 2 to 5%, and Al203 2 to %. :
Dolomite Dolomite Uses: Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination has become a widely heeded
