400C High Thermal High quality manufacturer fused magnesia alumina spinel for refractory fireproof brick is made of local top grade fireclay materials under the high temperature according to the lasted
national standard, which possesses even bulk density, high strength, low thermal conductivity and low impurity.
400C High Thermal High quality manufacturer fused magnesia alumina
spinel for refractory fireproof brick can be divided into three
process: Raw material, molding, burning.Generally, refractory brick
was molded by dry pressing. By means of mixing the material
uniformity in proportion and aging mixture some time. Then, pour
some powders into the module and dry pressing. After dry pressing,
the adobe need to pushed in the drying kiln to stoving or stay in
the air to drying. This progress will need about 3-5 days. After
this progress, then push the adobe into the tunnel furnace or
shuttle kiln to burning around 1300C. This progress will be need
about 5-7 days.
After burning, 400C High Thermal High quality manufacturer fused
magnesia alumina spinel for refractory fireproof brick will be
packed in pallet and leave the factory.
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.
