“…The potential claims for addition of mould powders are to disallow early solidification in the molten steel meniscus by thermally insulated slag layer; protect the molten steel from atmospheric reaction; absorbs de/re-oxidation products from the molten steel; prevent the steel adherence to the mould wall through provision of lubricating film of molten slag and enhance strand withdrawal, and modify heat removal properties in the mould [6]. Lubrication of the mould powder directly depends on softening/melting, crystallization, and viscous behaviour of the molten slag [7 8]. The change in mould flux compositions not only alters the crystallization behaviour but also the viscosity and subsequent lubrication properties.…”

“…Several researchers have reported that principal non-metallic inclusions (Al 2 O 3 , TiO 2 , MnO, ZrO 2 , etc.) in continuous casting of LCHMn steels affect the original property of raw mould powder as well as liquid slag [7 8 13,14]. The loss of MnO from steel results into appreciable changes to the variation of the mould heat transfer; however, the surface quality tends to worsen [15 16].…”

This study focused on multistage characterization techniques in developing an understanding of the abnormal casting behaviour of low carbon high manganese (LCHMn) steel. In addition to raw mould powder used for casting LCHMn steel, mould top slag samples were also collected for normal and abnormal casting conditions. Raw mould powder and top slag samples were characterized using XRF, XRD, and SEM-EDS to determine chemical composition, crystallinity and morphology. The chemical composition results revealed deviation of normal and abnormal behaviours from the mould powder due to the pickup of oxides of Al, Mn, and Ti. The SEM analyses of raw mould powder showed different granular particle sizes while pores and glassy/crystalline structure were seen for normal and abnormal behaviour at casting. CaF2, CaSiO3, and Na2CaSi3O9 were revealed as the mineralogical phases. There was a modified crystalline phase present in the abnormal behaviours at casting due to pickup of other oxides.
