چکیده
In the present study, viscosity of CaO–SiO2–FeO–Al2O3–MgO slag system was measured for recovery FeO in electric arc furnace (EAF) process using Al dross. Considering MgO-saturated operational condition EAF, composition at 1823 K with varying and Al2O3 concentrations. An increase decreasing temperature observed. The activation energy evaluated, change thermodynamically equilibrated phase considered. changes aluminate structure concentrations were investigated by Fourier-transform infrared spectroscopy, which revealed an [AlO4] tetrahedral increasing concentration. Depolymerization observed higher Raman spectra showed polymerization silicate network By associations between structures, a more highly polymerized achieved

متن کاملThe Phase Composition of Electric Furnace Slag
Elementary and phase composition as well as micrography of the electric furnace slag were examined. The base of slag is made from phases containing Fe, Mn and Ca. Grains differ in size and shape, they cling together to form bigger or smaller agglomerates, depending on separated fractions. Relative distribution of identified phases in separated fractions is presented and the possibility of phase...
