内容简介

The fused cast alumina-zirconia-silica (AZS) refractory is an indispensable material of the glass melting furnace, because of its outstanding corrosion resistance and low pollution to glass production. The exudation is one important index to evaluate the performance of fused cast AZS refractory products. In order to study the effects of chemical composition and microstructure on the exudation of fused cast AZS refractory materials, three types of fused-cast AZS refractory bricks(AZS33#, AZS36# and AZS41#) were selected from several companies as the research object, and their composition, bulk density, apparent porosity, the value of exudation, static corrosion rate and microstructure were discussed. The results show that the chemical composition, especially the content of SiO2 and Na2O, and the distribution of zirconia would greatly affect the content and viscosity of glass phase, thus affecting the glass exudation. This work will provide technical reference for the development of low exudation AZS refractories.
