Corundum Mullite Castable Description

Corundum mullite refractory castable is a kind of high strength unshaped refractory materials for sale in RS Company, which can be used in cement kiln. Corundum mullite castables can perform high properties such as high crushing strength, high temperature stability, thermal shock resistance, wear and chemical erosion resistance in lining of large power station boiler and other high temperature equipments. refractory corundum mullite castable can be used in steel furnace, cement kiln, glass furnace, iron making furnace, ceramic tunnel kiln and so on.

Properties of Corundum Mullite Castable

  • High strength,
  • Strong wear resistance,
  • Good erosion resistance,
  • Excellent thermal shock stability,
  • High temperature resistance.

Manufacturing Process of Corundum Mullite Castable

The main raw materials of corundum mullite castable is lightweight aluminium oxide aggregate, high quality pure natural mullite ore, and calcium aluminate cement as the bonding agent. corundum mullite refractory castable is made through high temperature burning by the advanced industrial furnace. corundum mullite flexural strength and compressive strength increase first and decrease then with the increase of heat treatment temperature. And when alumina micro power content is 5%, the flexural strength reaches to the top.

Composition of Corundum Mullite Castable

The content of Al2O3 is more than 90%, and the corundum mullite insulation castable with corundum as the main crystal phase are mixed with appropriate dispersants, coagulants, stainless steel fibers, which are compounded according to strict formula. Refractory corundum mullite castable has many characteristics, such as high temperature strength, wear-resisting and anti-scour, high heat conduction, heat shock resistance, corrosion resistance, good sealing and early condensation.

Application of Corundum Mullite Castable

Corundum mullite refractory castable has features of uniform expansion, excellent thermal shock resistance, high temperature volume stability, high temperature strength, high refractoriness under load, low high-temperature creep rate, high crushing strength, low linear dimensional change rate, high hardness, good resistance to chemical corrosion, spalling and wear resistance. Because of such characters, and corundum mullite insulation castable is durable in use and which is widely applied in different industrial kiln, high temperature furnace and other key parts of high temperature, such as:

  • Boiler, blast furnace, hot blast stove, heating furnace,
  • Ceramic tunnel kiln, cement kiln, coal burner,
  • Furnace door, feed opening, steel furnaces, iron making furnaces,
  • Combustion chamber, inclined flue,
  • Large power station boiler, glass kiln.
