Invited Lecture: Evaluation of high temperature performance of refractory materials

Abstract: Refractory materials are indispensable for the implementation of green and low-carbon high-temperature technologies developed in key basic raw material industries such as steel, non-ferrous and building materials, energy transmission and other fields, which are usually used as linings or functional components at high temperature for furnace, containers and smelting equipment etc. There are several important properties affecting service behavior and life span of refractory materials. Generally, in order to satisfy the application requirement, refractory materials should have good high temperature mechanical properties, excellent thermal shock resistance, and good corrosion resistance to surrounding medias. The test method and evaluation techniques are quite important for fully understand the comprehensive properties and service performance of the refractory materials. Therefore, this presentation describes how to characterize the key properties, including the modulus of rupture, thermal shock resistance, corrosion resistance and other properties. Furthermore, the effects of those property evaluations on the design and preparation of refractory materials are described based on some experiment results.
