Study on the Influence Factor of the Caustic Calcined Dolomite Based Compound Desulfurizer Melt Point

Abstract

Caustic calcined dolomite based compound desulfurizer by the silicon thermal reduction method was taken as study object. Effect of fluxing agent and heating agent on caustic calcined dolomite based compound desulfurizer melting point was studied. The result showed that heating agent was the major influential factor for the melting point of compound desulfurizer, melting point of the compound desulfurizer gradually reduced with the increase of heating agent. Fluxing agents of CaF2 and SiO2 were the minor influential factors for the melting point of compound desulfurizer. The lowest melting point condition for the compound desulfurizer was：7% CaF2+11% Al2O3+17% SiO2 + 56% heating agent.
