In the continuous improvement process, the study of the effect of EMS on steel homogeneity in an EAF is both experimental, computational, and metallurgical. EMS keeps the steel integrity by generating a consistent temperature and composition net from the molten steel, minimizing stirring and boosting mechanical strength (Zhang et al., 2020). The experimental method entails collecting steel throughout stirring at different points for chemical homogeneity and microstructural studies using spectroscopy and microscopy (Wang & Li, 2019). CFD modeling can also simulate the electromagnetic forces and fluid flow in the EAF to determine the adequacy of stirring (Chen et al., 2021).

Consequently, this enhances the stirring’s efficacy, and EMS influences the inclusion alignment and grain refinement, which are prerequisites for steel integrity (Kim & Park, 2018). These investigations can also evaluate if using EMS improves steel homogeneity in EAF. With simulations, engineers may change EMF voltage and coil placement to get the maximum stirring and produce the better EAF steel (Liu et al., 2022).
