Refractory low creep andalusite brick for hot blast stoves HBS
Andalusite is one mineral of natural kynaite brick minerals.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°C,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
it extensive is used to body of hot blast heater,torpdeocar liquid iron cover,glass kiln,electric furnace top,henting furnace.
Andalusite Brick has high cold crushing strength, high refractoriness under load, high thermal stability, good creep resistance and thermal shock resistance.
It is an alternative product for high aluminum bricks, used in the professional of the key parts of the furnaces. Andalusite brick has an excellent performance of good thermal shock resistance and creep resistance.
