Sulphide Capacities of CaO–Al2O3–SiO2–MgO–MnO Slags in the Temperature Range 1673–1773K

Sulphide Capacity of CaO–SiO₂–Al₂O₃–MgO System Relevant to Low MgO Blast Furnace Slags

“…[4][5][6][7][8][9][10] The reported sulphide capacity models can be classified as empirical models and theoretical models, as summarized in Table 4. The comparison of experimental data along with the estimated values by those models is shown in Fig.…”

Relationship between the common optical basicity models and the sulphide capacities of CaO-Al2O3-SiO2-MgO slag

“…The six sulphide capacity C S prediction models with high acceptance are summarised in Table 1, and include S-S model by Sosinsky and Sommerville [6], Young's model [7], Taniguchi's model [8], T-K's T a b l e 2. Chemical composition of analysed slags Heats % CaO % SiO2 % Al2O3 % MgO % MnO T (K) model by Tsao-Katayama [9] based on optical basicity Λ and the KTH model [17][18][19] in terms of defined interaction coefficient of component i to jξ…”

“…This work is an attempt to compare the relationship between optical basicity and, in literature, available models of calculating sulphide capacity of ladle slag [6][7][8][9].…”

Estudo da substituição da fluorita por alumina ou sodalita e de cal por resíduo de mármore em escórias sintéticas dessulfurantes.

“…Portanto, é necessário calcular a capacidade de sulfeto através de equações que considerem essas escórias. Por isso, diversas pesquisas (33,34,35,36,37) desenvolveram relações para obter a capacidade de sulfeto a partir da temperatura do processo e da composição química da escória dessulfurante.…”

“…Nessas circunstâncias, Shankar et al (34) e Taniguchi et al (35) propuseram recentemente dois modelos para prever com precisão a capacidade de sulfeto para (41)   …”
