Crystallization of Free Lime and Magnesia from Molten LD-converter Slag

Effect of Reheating and Quenching on the Cathodoluminescence Intensity of Free Lime in Steelmaking Slag

“…Several black or gray particles were observed in both samples; according to EDX analysis, these particles were made of wüstite (FeO-MnO solid solution). The precipitation of wüstite in free lime is reported in previous reports (Niida et al, 1983;Inoue & Suito, 1995). When the samples were tilted to a different diffraction condition in STEM observation, the distributions of dislocations were not drastically changed, indicating that Figure 2 represents typical distributions of dislocations in the samples.…”

A Bogue approach applied to BOF slag

“…The generation of Ff is mostly dependent on the cooling conditions during the post-processing of the BOF slag [16,33,43]. In BOF slag under industrial cooling settings, f-C originates from three different sources: undissolved flux particles [44,45], exsolution from C3S that forms alongside C2S, and eutectic f-C that occurs at the conclusion of the crystallization sequence. It's possible that the f-C content is highly changeable and difficult to forecast because these origins depend not only on the total CaO content but also on the cooling conditions and oxygen blowing time in the basic oxygen steelmaking process.…”
