DESCRIPTION

Interactions between a tundish working lining and molten steel were investigated using industrial samples and laboratory testing. A periclase-based dry vibrational lining containing 30 wt.% olivine was sampled from a production facility and examined. Cathodoluminescence imaging, secondary electron microscopy, energy-dispersive spectroscopy and x-ray diffraction analysis were performed to characterize the interactions. An experiment was developed to replicate the conditions found in a production tundish on the laboratory scale. Results comparing interactions observed in the laboratory lining tests and commercial samples for the lining material are presented and discussed.
