Effects of Chemical Composition and Microstructure on the Exudation of Fused cast AZS Refractory Materials

摘要：

　　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 of important indexes 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,we selected three types of fused-cast AZS refractory bricks(AZS33#,AZS36#and AZS41#)from several companies as the research object,and the composition,bulk density,apparent porosity,the value of exudation,static corrosion rate and microstructure of them were discussed.The results showed that the chemical composition,especially the content of SiO2and 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 refractory.
