Influence of B2O3 on Crystallization Behavior of Cr-bearing Phase in Stainless Steel Slag
Abstract
This paper discussed the effects of B2O3 addition on the crystallization of Cr-bearing phase in synthetic stainless steel slag after different duration of molten slag at 1500 oC. The crystallized slag with or without B2O3 were then characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM) equipped with energy dispersive X-ray spectrometer (EDS) and electron probe microanalysis (EPMA). The results show that B2O3 does not change the phase components of slag. However, the growth of Cr-bearing phase, magnesiochromite spinel, is enhanced and the content of Cr2O3 in the phase attains 52.66 wt.%, higher than that in the slag without B2O3.
