Abstract

Thermal shock damage in the refractory lining of steelmaking installations is modelled using an experimentally validated constitutive damage framework which is coupled incrementally with a thermo-elastic FE package. Both non-local elasticity-based damage induced by temperature gradients and thermal damage induced by a uniform temperature increase contribute to the total damage. The non-locality is spatially discretized using a Galerkin approach within a finite element context. The thermal shock damage in a snorkel of a steel degassing installation as well as in the refractory lining of a steel ladle is modelled to demonstrate the applicability of the computational platform.
