Mullite - corundum material widely used in of kiln furniture manufacturing at home and abroad in its excellent performance . Seat late in the development of our country deflection core setter , has not developed a high-end mullite - corundum load bearing seat . Firstly, by comparing the advantages and disadvantages of various kiln furniture materials , the final choice mullite , corundum material as a load bearing seat material ; thereby reducing the sintering temperature of the products by adding three different mineralizing agent , and to study them product performance and composition , and ultimately determine the reasonable amount of mineralizer ; Second , by changing the relative content of mullite , corundum , mullite and corundum particles interpenetration , constitute the skeleton and optimize the structure of the products, integrated performance ; Finally, by adding the corundum powder and α -Al 2 O 3 powder , and to extend the holding time , the sintering shrinkage of the article is improved , in laboratory conditions developed under two thermal expansion coefficient , good thermal stability , excellent load bearing seat material . Through field experiments , and ultimately determine the main crystalline mullite phase process recipe setter seat has a better performance in the actual production trial production in accordance with the formula , and lower cost , higher life , the 80 times over the life of the domestic advanced level .
