內容簡介The thermal shock resistance of self-flow alumina based castables is investigated due to natural cooling, compressed air cooling and water cooling (quench) methods respectively. The residual Young's modulus as well the residual bending strength are taken into account in order to compare the influence of different testing methods on the results. The pore size distribution, SEM analysis and computerized tomography are used to assist the study. The integrity of the sample is damaged dramatically by the application of water quenching test and does not reflect the real state of the thermal shock resistance of the castables in practice. The results based on compressed air cooling (quench) method are similar with that based on natural cooling process and are suitable to evaluate the thermal shock performance of the alumina castable samples.
