Failure Analysis of Refractory Cup under Thermal Loading and Chemical Attack Using Continuum Damage Mechanics
Refractories are widely used for the linings of furnaces and vessels of the glass-making, steel-making and energy-production industries. The refractory linings are subjected to significant thermal loading and chemical corrosion which lead to spalling and cracking. A continuum damage mechanics based analytical model is developed to study the failure behavior of an alumina refractory exposed to high temperature and corrosive environments. The predicted damage pattern is compared to that observed in brick in a cup test. This work provides a mechanics and material science based method for the failure analysis of refractories. It would serve as a guide in the development of refractories
