Development of Andalusite Bricks for Hot Blast Stove

摘要

Low-creep andalusite bricks are characterized by high refractoriness under load,good anti-creep property,high mechanical strength,low porosity,good thermal shock resistance,etc.In this study,low-creep andalusite brick specimens were investigated in the lab using mullite,bauxite and andalusite.Andalusite with the different particle sizes were used in the experiment and the specimen with the best property was selected as the production standard.In addition,the industrial produced low-creep andalusite bricks were compared with other low-creep bricks.The results show that the developed low-creep andalusite bricks is an excellent material for hot blast stove.
