Mullite brick features

Refractoriness higher, up to 1790 ℃ or more. RUL starting temperature 1600 ~ 1700 ℃. Cold crushing strength 70 ~ 260MPa. Good thermal shock resistance. Sintered mullite bricks and fused mullite brick two kinds. Sintered mullite brick high bauxite as main raw material, adding a small amount of clay or raw bauxite as binder, after molding, firing and made. Fused Glass beads mullite brick high bauxite, alumina and fireclay as industrial raw material, fine-grained charcoal or coke as a reducing agent, to produce fused after forming method using the restore. Fused mullite sintered mullite crystallization than big, good thermal shock resistance than sintered products. Their performance depends on the content of the high temperature alumina brown fused aluminum oxide and mullite phase uniformity of the glass. Mainly for roof stove, blast furnace body and bottom, glass melting furnace regenerators, ceramic sintering furnace, petroleum cracking system dead lining and so on.
