SUMMARY:Improvement in Thermal Spalling Resistance for Cold Start Alumina-
 Graphite Ladle Shroud - Sudipta Palit

DESCRIPTION:Cold start ladle shrouds (without preheating) are widely used 
 now-a-days and require very good thermal spalling resistance mainly where 
 fluctuation of casting temperature is very severe. Considering high therma
 l spalling behavior cold start ladle shrouds are prepared with Al2O3-Carbo
 n or Al2O3-SiO2-Carbon (here written as AG) systems. One of the most impor
 tant parameters is to optimize the mix granulometry to improve the thermal
  spalling resistance. \nIn this study\, by enhancing finer grain sizes of 
 AG mixes\, the modulus of elasticity (MOE) of the product is reduced and o
 ne new ladle shroud has been developed having better thermal spalling resi
 stance. The improved ladle shrouds are used at several customers end with 
 trouble free casting operations.
