Abstract Scope |
In many cases of refractory engineering the global loads (stresses, strains) are caused by restrictions of the refractory’s thermal expansion by rigid external structures such as steel shells. In this case creep will lead to relaxation resulting in a decrease of these stresses. In this study we show the impact of a Norton-Bailey based creep model on stresses during a finite element analysis using a simplified furnace lining model. The model considers a three-dimensional cross section of the lining including the steel shell. A finite element analysis including transient heat transfer and thermo-mechanical stresses and strains was conducted. The impact of considering creep on the stress distribution is shown. |
