 · This is now gaining the spotlight but still remains a grand challenge in the iron and steel industry (ISI). To address this issue, centrifugal-granulation-assisted thermal energy recovery (CGATER) has been proposed and is regarded as the leading slag treatment technology for its superior merits in energy saving & carbon footprint reduction.

 · High-temperature waste heat from the iron and steel industry, as shown in Fig. 1, are mainly stored in products, molten slag and waste gas .Molten slag, as a kind of by-product during the steelmaking process, is exhausted in extremely high temperature and thus, it carries a great deal of high-grade heat accounting for 10% of waste energy in …

Molten iron desulfurization slag (DS) is the tail slag produced in the pre-desulfurization process of molten iron. Molten iron desulfurization produces approximately 7–9 kg/t of DS (Zhang and An-Jun 2009). The main components of DS are Ca(OH) 2, CaSO 4, CaF 2, CaCO 3, CaS, and Ca 2 SiO 4 (Tong et al., 2016).
