Corrosion Behavior of Tundish Refractories by Molten Steel and Tundish Flux

Alternative Title

Interactions between Tundish Refractories, Tundish Fluxes and Molten Steel

Abstract

Interactions between dry vibratable tundish lining material, tundish flux and molten steel were explored using a laboratory-based crucible experiment. A periclase-based dry vibratable tundish lining material containing 30 wt.% olivine was selected for investigation. The flux used was one that is commercially available and was provided by industry sponsors. The steel grade investigated was low-carbon, aluminum-killed and calcium-treated with titanium addition. Cathodoluminescence imaging, secondary electron microscopy and energy-dispersive spectroscopy were performed to characterize the interactions. The linings are compared to determine the impact of material selection on lining corrosion, spinel formation and steel cleanliness.
