It is used for the construction of furnace lining and insulating layer. The surface contact temperature shouldn't be higher than 1350℃ when it is exposed to flame directly.
High alumina insulation brick is also known as light weight alumina insulating brick. It is a new type of light weight insulating material which contains approximately 48% alumina, mullite and glass phase or corundum.
It is used for the construction of furnace lining and insulating layer, and the parts without erosion or scouring action of intense high temperature melting material. The surface contact temperature shouldn’t be higher than 1350℃ when it is exposed to flame directly.
