Abstract

Exposure to high temperatures is one of the most important deterioration processes of building structures during their service life. In order to understand the changes in the working capacity of refractory blocks used in oil drilling and arson operations, samples were taken of refractory blocks that had been heat treated and not heat treated in the spray cell, the physical and chemical properties, phase composition, microstructure, etc. of the samples were analyzed and studied. The results show that when refractory blocks are sintered under high temperature, the aluminate, aluminum phosphate, etc. of the internal cementing materials will decompose, forming Al₂O₃ as a loose and porous structure. After high temperature treatment in the combustion cell, the internal structure and composition of the refractory blocks have better Thermal stability, volume and thermal conductivity basically do not change under the condition of 1200℃; the compressive strength and flexural strength of unheated refractory blocks are 20.56 Mpa and 3.1 Mpa respectively. Heat treatment makes the compressive strength and flexural strength of refractory blocks respectively. Reduced by 21.52% and 43.01%. The research results provide a reference for the service performance of refractory blocks during the use of combustion cell.
