High refractoriness under load andalusite refractory high alumina andalusite checker brick for hot blast furnace
Andalusite is one mineral of natural kynaite brick minerals, mainly used as low creep refractories like andalusite checker bricks.
Its structure is dense and true density is one number between 3.10g/cm3 and 3.16 g/cm3.Its true dnestiy is basically similat to mullite. It gradually change to chimney mullite crystal of paralleling with original crystal in 1350 degree celsius,lesser volume effect and basically invariable bubble.
So it can be main material of manufacture refractory products.Characteristic of andalusite brick is below as stable volume,better palling resistance,unti-creep,higher initial softening point under load,iron dreg better permeability and chemical stability and so on.And then it extensive is used to body of hot blast heater,torpdeocar liquid iron cover,glass kiln,electric furnace top,henting furnace.
Low Creep Andalusite Brick:Made from mullite and andalusite as
starting materials, the bricks are processed into shapes by molding
under high pressure and sintering at high temperature, with
features of lower impurity contents.
