For slag B, the Fe t O content in the solid solution was higher than that in slag A. This is because Fe 2+ ions have the same ionic valence as Ca 2+ ions, and the radius is smaller than that of Ca 2+; thus, Fe 2+ ions can replace Ca 2+ ions and easily enter the C 2 S–C 3 P solid solution (Du et al. 2018c).

Figure 1 shows the effect of the initial slag composition on [Al] s and T.O. in steel. When basicity of the initial slag increased from 1.0 to 2.3, shown in Figure 1(a), the T.O. in stainless steel dropped from 24.5 to 14.7 ppm and the [Al] s content rose up from 3.7 to 29.5 ppm, indicating that a high-basicity slag was beneficial to improve the cleanliness …

Dephosphorization of HC Droplets as a Function of Slag Basicity. In this study, three different slags, V = 0.91, 1.62 and 2.58, were used to investigate the influence of basicity on dephosphorization behavior of HC droplets. HC droplets reacting with slags with V = 0.91 at 1853 K and V = 2.58 at 1923 K had been studied in previous work by some ...

From Table 4.1 it is evident that on losing three electrons, the Fe 3+ cation with more charge is smaller than the ion Fe 2+ that is formed by losing two electrons. Thus, the R c /R a ratio as well as the CN control the structural arrangement of the ions. Hence, from simple geometrical considerations, the ionic structure of the oxide can be …

Smelting furnaces produce liquid Cu–Fe–S matte (usually 60–70% Cu), which must have its sulfur and iron removed to make copper metal. This is most frequently done in submerged-tuyere Peirce–Smith (Fig. 4) and Hoboken converting furnaces using air (often slightly O 2-enriched) as the oxidant.The process is similar to submerged-tuyere smelting except that …
