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 thermal spalling behavior cold start ladle shrouds are prepared with Al2O3-Carbon or Al2O3-SiO2-Carbon (here written as AG) systems. One of the most important parameters is to optimize the mix granulometry to improve the thermal spalling resistance.
In this study, by enhancing finer grain sizes of AG mixes, the modulus of elasticity (MOE) of the product is reduced and one new ladle shroud has been developed having better thermal spalling resistance. The improved ladle shrouds are used at several customers end with trouble free casting operations.
