China 8 Year Exporter Magnesite Refractory Bricks - Burned Micro porous Alumina carbon Bricks Al2O3 55% – Rongsheng factory and manufacturers | Rongsheng Detail:

Alumina Ccarbon brick is a kind of carbon combination refractory material which made of alumina and carbon materials, sometimes mixed with silicon carbide, metal silicon and other organic bonds, such as resin. alumina carbon fire brick variety has aluminum carbonaceous slide brick, cast nozzle brick, alkali resistant aluminum carbon brick and blast furnace aluminum carbon brick. alumina carbon refractory brick features are strong corrosion resistance, good thermal shock stability, high strength and high thermal conductivity.

Alumina Carbon Brick Process

Alumina carbon brick is made by adopting special grade bauxite clinker, corundum, graphite and mid alumina as main raw materials, combined with several kinds of super fine powder additives. Process of alumina carbon refractory brick is adding the Aluminum oxide, carbonaceous, silicon powder materials and small amounts of other raw materials to the raw material, then use asphalt, a binder, resin or after ingredients, mixing, pressing forming, around 1300 ℃ sintering in reducing atmosphere.

Features of Alumina Carbon Brick

  • strong corrosion resistance,
  • good thermal shock stability,
  • high strength,
  • high thermal conductivity.

Classification of Alumina Carbon Brick

Alumina carbon brick can be divided into two classifications, magnesia alumina carbon brick and alumina magnesia carbon brick.

Magnesia alumina carbon brick, with high grade magnesite, corundum, spinel and graphite as raw materials, bonded by resin, are characterized by good slag resistance.

Alumina magnesia carbon brick, with high grade bauxite, corundum, spinel, high purity magnesite and graphite as raw materials, bonded by resin, are characterized by erosion and corrosion resistance, spalling resistance.
