Characterization of Corrosion Mechanisms Occurring in a Sintered Sic Exposed to Basic Coal Slags

The high‐temperature reactions occurring between an a‐Sic and a basic coal slag were examined. The resulting corrosion behavior was found to involve at least three mechanisms, including passivation of the Sic via SiO2 formation, dissolution of the SiO2 by the coal slag, and formation of a localized Fe‐Ni silicide. This mechanism, which dominated when the slag thickness exceeded 100 μm, was also responsible for the degradation in high‐temperature strength.

Tundish Temperature Control

Argon stirring, slag thickness, and ladle condition influence metal temperature in a tundish. How hot should a preheated ladle be?
