Dolomite – Its Processing and Application in Iron and ...

Calcined dolomite is a material that plays an important role in the steel sector, both for its purifying action and for the protection of refractory linings. Calcium and magnesium oxide or calcined dolomite are obtained from dolomitic minerals such as calcium carbonate and magnesium (Ca Mg (CO3) 2, through the calcination process.

of calcined dolomite R. Winand, M. van Gysel, A. Fontana, L. Segers and J.-C. Carlier Synopsis It is well known that MgO can be reduced by carbon at attnospheric pressure at temperatures in the range 19So-2000°C. A study was made of the selective reduc-tion of MgO.CaO by carbon under moderate vacuum (1 mm Hg) and at temperatures of about 1400°C.

Import Data and Price of calcined dolomite | Zauba

Calcined dolomite, calcium magnesium oxide, (CaMg(O) 2) How it's produced: By heating the mineral dolomite (CaMg(CO 3) 2). Uses: In steelmaking, both quicklime and calcined dolomite are used as a flux and slag conditioner and to prevent the steel from oxidising. This process also collects impurities that are damaging to the steel.

Dolomite in iron and steel industry is normally used in three forms. These are (i) raw dolomite which is also the natural form of dolomite, (ii) calcined dolomite, and (iii) sintered dolomite. When dolomite is used as a fluxing material then it is used as either raw dolomite or calcined dolomite.

Lime and Calcined Dolomite for Use in Steel Plant – IspatGuru

Dolomite is sometimes used both in the raw and calcined form as refractory material for hearth maintenance and for banking door in open hearth furnaces. For most refractory uses, it is desirable to subject the dolomite to a heat treatment at a high temperature of the order of 1700ºC, to shrink the material thoroughly and render it less reactive.
