Refractory Masonry

Mortarless refractory masonry structures are widely used in the steel industry for the linings of many high-temperature industrial applications including steel ladle. The design and the optimization of these components require accurate numerical models that consider the presence of joints as well as joints closure and opening due to cyclic heating and cooling. The present work reports on the formulation, numerical implementation, validation, and application of homogenized numerical models for simulation of refractory masonry structures with dry joints. The validated constitutive model has been used to simulate a steel ladle and to analyze its transient thermomechanical behavior during a typical thermal cycle of steel ladle. 3D solution domain, enhanced thermal and mechanical boundary conditions have been used. Parametric studies to investigate the impact of joints thickness on the thermomechanical response of the ladle have been carried out. The results clearly demonstrate that the thermomechanical behavior of mortarless masonry is orthotropic nonlinear due to gradual closure and reopening of joints with the increase and decrease of temperature. Also, resulting thermal stresses increase with the increase of temperature and decrease with the increase of joints thickness.

Abstract Temperature-dependent die warpage measurements show the possibility to analyze the thermomechanical behavior during assembly, e.g. within soldering processes. The warpage data acquisition is realized by confocal chromatic white light profilometry in combination with a precision heating/cooling chuck encapsulated in a chamber with optical access. The combination of these two tools allows precise die warpage evaluation under varied device temperature up to +400°C. This method helps to solve emerging challenges due to warpage during assembly of state of the art packages including thin dies and stacked dies as in e.g. 3D-SIPs.
