Sillimanite brick is a kind of refractory brick made by mixing, molding, high temperature burning with bauxite as the raw material and add silica chalk and clinker. Owing to the sillimanite bricks appear mullite phase in the process of high temperature burning, so it can belong to mullite brick; From the aspect of alumina content, it also can belong to high alumina refractory bricks. The refractoriness of sillimanite brick is 1770-1830℃ and the RUL is 1500-1600℃.
Good creep resistance, low creep rate in high temperature environment.
Good thermal shock resistance
High refractoriness under load
Good resistance to gas erosWhat are the Application Place of Sillimanite Brick Used in Hot Blast Furnace?
Application of Sillimanite Brick
The application of sillimanite brick used in hot blast furnace: hot blast furnace main pipe and branch pipe, regenerative chamber, combustion chamber and other parts, hot blast furnace is a thermal equipment with stable working environment for a long time, which is matched with iron making hot blast furnace, because the hot blast furnace need creep resistance of refractory brick, and the sillimanite bricks have the characteristics of creep resistance, can be used in high temperature for a long time without deformation, so sillimanite bricks can be used in many parts of hot blast furnace.
