The calcination process normally takes place at temperatures below the melting point of the product materials One of the most common applications is as a step in the production of Portland cement in which calcium carbonate limestone is calcined at around 850176C to
In case of the secondary steel making processes such as ladle furnace and vacuum degassing etc., lime is used to perform key functions, such as fine tuning of steel chemistry, lowering of the oxygen content, reduction in the inclusions trapped by the slag, the adjustment of steel temperature, removal of additional impurities, and the prevention of reabsorption of impurities from slags.
The calcination of the limestone takes place at a relatively moderate temperature, typically around 900 deg C to 1100 deg C. This makes the kilns ideally suited for producing moderate and high reactivity lime with a low residual CO2 level.

Calcination Of Dolomite. Study of using lightburned dolomite ores as raw material for example for t800t0 where the first t denotes calcination temperature and the second t represents calcination time the mos cement derived from lightburned dolomite at a calcination temperature of 800 c with calcination time of 0 h which was cured in 1 d the compressive strength was 13 mpa but the compressive
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide).The chemical equation for this reaction is . CaCO 3 + heat CaO + CO 2. This reaction takes place at 900 #176;C (1,650 #176;F) (at which temperature the partial pressure of CO 2 is 1 atmosphere), but a temperature around 1000 #176;C (1800 #176;F; at which
