Yu Mou, Sisi Han, Yanrong Zhang, Kai Wu, Xinrui Shen
TL;DR
This study analyzes how different refractory brick parameters affect structural performance in high-temperature environments using a thermal stress model.
Contribution
The paper introduces a novel approach combining brick number, thickness, and material in a coupled thermal stress model.
Findings
Brick number has a greater effect on vertical displacement and compressive stress than brick thickness.
Brick material significantly influences vertical displacement and compressive stress more than brick number.
Material properties have the most impact on structural performance, followed by brick number and then thickness.
Abstract
The selection of refractory bricks significantly impacts the operational performance of brick structures in high-temperature environments. In this study, a coupled thermal stress model of a refractory brick structure was established and validated by means of thermal expansion experiments. This paper innovatively combined the brick number, brick thickness, and brick material to investigate their influence on brick structural performance. The results indicated that the influence of the brick number on the temperature was less significant than that of brick thickness. However, the brick number had a greater effect on vertical displacement and principal compressive stress than brick thickness, with the maximum differences being 342.3% and 28.9%. Compared to brick thickness, brick material had a more significant effect on vertical displacement and principal compressive stress, with the…
