Study on Effects of Heat Preservation Time on Key Product Phases of High-calcium Vanadium Slag in Roasting Stage AITranslate
Abstract AITranslate
The variation characteristics of particle size,morphology and micro-area composition of the key products of high-calcium vanadium slag in roasting stage were analyzed by scanning electron microscope and energy spectrometer.And the influence of heat preservation time on the roasting products of vanadium slag was studied.The results show that with the intension of heat preservation time,the particle size of iron oxide and pseudobrookite gradually increases;iron oxide gradually changes from regular granular crystal to irregular strip or bead-like crystal stock;pseudobrookite gradually changes from plate-like single crystal to irregular crystal stock;calcium-manganese vanadate gradually changes from dispergated form to locally aggregated form.As the heat preservation time increases,the overall change of the micro-area composition of iron oxide and pseudobrookite is relatively small,and calcium-manganese vanadate gradually changes from a mixed phase dominated by calcium vanadate to calcium vanadate with relatively high purity.
