Otherwise a material assessment based on standard test procedures would lead to the wrong conclusion. Numerical studies Comparative FEM analysis of two burner tiles made of commercially available cement bonded- and phosphate bonded castables have been conducted in order to determine the thermo-mechanical behavior of the different materials during the critical heat up. The tile used for the modeling is a burner tile of an annealing furnace. A heat up was considered on this axi-symmetric burner tile as indicated in Figure 3. The thermal boundary conditions are indicated in Figure 4. A heat up time of 48 hours was considered. Figure 3. The axi-symmetric burner geometry. Figure 4.
