| Abstract |
The effects of bascity and MgO in iron ore sinter on softening and melting down behaviors under load were investigated. The optmum range of basicity in iron ore sinter for softening and melting down properties under load was considered 1.7∼1.8, which was confirmed on the phase diagram of CaO-SiO₂-MgO-10% Al₂O₃ system. Mineral phases melting at high temperature were formed with the increase of MgO in iron ore sinter, which affected the enhancement of starting temperature for softening and melting down, and the optimum concentration of MgO was confirmed at the vicinity of 1.8wt.% The melting down phenomena of iron ore sinter of homogeneous slagmelt processes during softening and melting down were able to be analyzed on the phase diagram of CaO-SiO₂-MgO-10% Al₂O₃ system. |
