Properties:
Super bauxites and corundum mullite were used as main raw materials in the production of low creeping high alumina bricks series for hot blast stoveŁ®High pressure pressing and sintering in high temperature makes very good results of  the products in RUL,creeping rate and thermal shock resistanceŁ®They are the best choice for largeŁmiddle hot blast stovesŁ®
