Abstract

In coal boilers or in steel ladles, the refractory linings anchored (or not) to the steel structure (casing) are submitted to important thermal loading (heating and cooling) which conducts to lining cracking (due to the difference between the thermal expansion coefficients). In a first time a 3D approach allows to analyse the problem at the anchor scale: a smeared crack model allows to compute the damage in the castable. But since a boiler contains thousand of anchors, it is not possible to compute a complete structure with this model. So, a second approach was developed with a two-layer shell equivalent to the anchored lining and the casing. This model was identified with an inverse method, using results from the first approach and validated by a bending test performed on a refractory lining specimen. The damage computing of a structure shows that it is very important to take into account the expansion joints.
