Description
Aluminum carbon brick is Al2O3 and C as the main component
containing Al2O3 *5% **5%, containing C7% **5% of the
refractory. Can be divided into two types of burning brick and not
burning brick.
Aluminum carbon brick refractory high, good chemical stability,
corrosion resistance. Such as adding ZrO2 in the ingredients,
can get good thermal shock resistance. The compressive strength of
calcined aluminum carbon brick containing Al2O3 *2% **5%, C7%
*8% is up to ******0MPa, bending strength at ***0 ºC is *5MPa,
containing Al2O3 *5% **6%, C + SiC*0% **7% Of the burning
aluminum carbon brick pressure strength of ****8MPa.
Burning aluminum carbon brick is a ceramic or ceramic-carbon
composite material, it is used for a large number of continuous
casting with sliding water slide, long nozzle, immersion nozzle,
the mouth of the brick and the whole plug and so on. Non-burning
aluminum carbon brick is a carbon-bonded material, because the
oxidation resistance is better than magnesium carbon brick,
anti-Na2O slag erosion performance is excellent, so in the hot
metal pretreatment equipment has been widely used.
The series of products baitum clinker, corundum, graphite as the
main material, into a variety of differential additives, with good
micro-target, alkali-resistant performance, high thermal
conductivity. It is suitable for carbon-containing refractory
products made of corundum (or bauxite, mullite) and graphite as the
main raw material for the furnace wall, furnace belly, cold-walled
aluminum brick and so on. According to the different manufacturing
process can be divided into aluminum carbon brick burning aluminum
brick and not burning aluminum carbon brick.
Manufacture of burning aluminum carbon brick process points: the
main raw material in the alumina mixed with carbon raw materials,
and add silicon powder, SiC powder, aluminum powder and other small
amount of other raw materials to phenolic resin or asphalt as a
binder, by ingredients, mixed , Isostatic pressing (or press
forming), firing in a reducing atmosphere.
