Influence of Teeming Flux on Industrial-Scale Fe-Mn-Al-C Ingot Production

Abstract

This report documents the characterization of Fe-Mn-Al-C steel ingot and slab sections produced during an industrial-scale trial heat. Optical microscopy and composition analysis were performed on sections of an as-normalized ingot and two partially broken-down slabs. Samples were examined from various locations along the length and depth of the ingots and slabs. The as-cast and partially recrystallized microstructures were evaluated and compared with Scheil simulation results. Composition analysis showed that the teeming flux selection affected the resulting ingot composition, whereas composition fluctuation in the ladle during teeming was not significant.
