Abstract
IN THE PRESENT STUDY, AN ANALYSIS OF THE DEPHOSPHORIZATION EFFICIENCY OF A STANDARD MIXTURE M1 (60.28% FEO, 37.24% CAO, 1,51% SIO2) AND FIVE OTHER MIXTURES WAS PERFORMED. MIXTURE MASS (60,70 AND 80G), WORKING TEMPERATURE (1400ºC AND 1350ºC) AND ADDITION METHOD (ONE-STEP AND TWO-STEP) WERE VARIED. EXPERIMENTAL TESTS WERE CARRIED IN A HEATED RESISTANCE FURNACE FROM FORTELAB, AT TEMPERATURES OF 1400°C AND 1350ºC, WITH CONSTANT AGITATION OF 450 RPM. AT THE END OF EXPERIMENTS, IMAGES FROM THE CRUCIBLE SURFACES WERE CAPTURED AND ANALYZED ON QUANTIKOV 15.86 AND SIMULATIONS WERE PERFORMED ON FACTSAGE 7.3 TO DETERMINE FINAL SLAG PROPERTIES. MIXTURE M1 ACHIEVED BETTER EFFICIENCY THAN THE OTHER VARIATIONS IN ALL THE STUDIED CONDITIONS. IT WAS OBSERVED THAT LOWER PARTICLE AGGLOMERATION (LOWER AVERAGE AREA AND AVERAGE DIAMETER) AND BETTER FINAL SLAG PROPERTIES IMPROVED DEPHOSPHORIZATION EFFICIENCY AND THAT THE CORRELATION BETWEEN AGGLOMERATION PROPERTIES AND THE DEPHOSPHORIZATION EFFICIENCY WAS APPROXIMATELY INVERSELY PROPORTIONAL.
