Limestone Fluxed Pellets

Effect of adding limestone on the metallurgical

10/08/2015  Limestone fluxed pellets are highly porous and therefore very reducible but physically weaker than non-fluxed ones. The CCS distribution (see Fig. 13 ) is broad and the standard deviation is high for both pellet grades; therefore, the average CCS value alone is not a proper indicator of the mechanical properties of the pellets.

Effect of limestone and dolomite flux on the quality

01/02/2021  It indicates that fluxed pellets with different proportions of limestone-dolomite (LD1, LD, LD2, and LD3) have lower RDI than L and D pellets. It is due to the presence of calcium silicate melts, and SFCA in the fluxed pellets with both limestone and dolomite. Calcium silicate melts impart more binding strength as compare to hematite bonds

01/06/2017  Limestone fluxed pellets were prepared at varying basicity (0 to 0.8) and pyroxenite fluxed pellets at varying MgO contents (0 to 3%) to study their effect on the metallurgical properties. Fired pellets were tested for their strength, RDI, reducibility and swelling. Microstructural studies, optical and SEM-EDS were carried out to quantify different phases and their chemistry. Acid pellets exhibited poor quality whereas limestone pellets

Characterization of bonding and crystalline phases

In limestone-fluxed pellets with bentonite as a binder, although formation of calcium ferrite was noted at the basicity of 0.8, its formation in appreciable quantities was delayed until the basicity of 1.6. For the pellets produced with a combination of dolomite and limestone, even at the basicity of 1.6, only minor amounts of this phase were present. In these pellets, some magnesioferrites were formed which did
