Calcined Dolomite - Digitalfire

Dead-burned dolomite is produced when dolomite is calcined at very high temperatures. It is used both as a refractory product in granular form to repair linings and for making the bricks used in the refractory linings of casting ladles and cement kilns. This refractory work well for ladles because it creates MgO in solution in the slag, which ...

Calcined dolomite SMA Mineral

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. Calcined dolomite also protects the refractory lining of the steel furnace, oxygen converter and ladle furnace. Both products can be supplied in ...

Effect of natural dolomite calcination temperature on

Natural dolomite was calcined at 700–900 °C under air and an Ar gas flow atmosphere to characterize its sorbency potential for borate.A sequential decarbonation occurred with increase in calcination temperature, that is, transformation of CaMg(CO 3) 2 to MgO and CaCO 3 up to 700 °C and CaCO 3 to CaO from 700 to 900 °C. The surface molar ratio of Ca/Mg decreased from 1.6 to 0.6 by ...

Hot Gas Cleaning and Upgrading with a Calcined

2019. 5. 25.  Cleaning and upgrading of the hot raw gas from a biomass gasifier, bubbling fluidized bed type, is studied at small pilot plant scale (10 kg biomass fed/h) using a calcined dolomite located downstream from the gasifier. Gasification is made with steam−oxygen mixtures at 800−850 °C and atmospheric pressure. Main variables studied are the gas residence time in the bed of dolomite and
