400C Refractories High quality manufacturer fused magnesia alumina
spinel for refractory fireproof brick is an ideal insulating
refractory refractory material, with advantages of high strength,
low thermal conductivity, good insulation property and low price.
For various industrial kilns & furnaces, it is a kind of
essential refractory for energy saving and temperature
preservation.
400C Refractories High quality manufacturer fused magnesia alumina
spinel for refractory fireproof brick is also called high alumina
insulating brick. It contains more than 48% Ai2O3 and mainly
consists of mullite and glass phase or corundum. It is usually made
of high bauxite and a small amount of clay. After the raw materials
are grounded, it is made into mud. Then it is cast and molded and
fired at 1300~1500℃. Sometimes industrial alumimum is used to
replace bauxite. Inorganic matter is added as ignition loss
substance in order to increase the porosity of the refractory.
400C Refractories High quality manufacturer fused magnesia alumina spinel for refractory fireproof brick refers to a heat-insulating refractory product made of bauxite with an Al2O3 content of not less than 48%.
Features:
- Mechanical strength
- High temperature
- Excellent resistance to spalling
- Resistant to corrosion
- Excellent load-bearing properties
Application:
• Industrial furnace, glass furnace
• Chemical industrial furnace
• Utility industry furnace lining
• Heat insulation ventilation wall
High quality factories refractories material alumina brick are widely used in thermal equipment in metallurgy, petrochemical, machinery, electric power, building materials, aerospace, shipbuilding and other industrial sectors.
