113Abstract Refractory materials are used for the lining of many industrial vessels includingsteelmaking ladles and mixers where the structures are exposed to high temperatures aswell as mechanical and hydrodynamical lads This thesis reports the procedure and resultsof thermo mechanical modeling of the refractory lining of a steelmaking mixer To accountfor structural behaviors of a mixer with complex geometry and multi componentsrefractory linings a complete three dimensional model is used in the simulation Thehydrodynamic load exerted on inner surface of mixer from the molten iron is determinedvia a FVM analysis A heat transfer analysis including a radiation model is also used todetermine the thermal loads The calvulated loads are then used in a stress analysis toinvestigate the response of the lining structure to service loads and the interaction betweenthe layers of the lining A special approach is proposed for the modeling of expansionjoints behaviors The obtained results appropriately predict the temperature distributionwithin the structure and can be used for improvement of lining design and the choise ofmaterials
