High purity mullite insulating lightweight refractory fire brick
Insulating Fire Brick (IFB) is an excellent high temperature
insulation product, and offers a combination of insulating
properties with load bearing ability. IFBs are suited to
applications above 1000°C or 1832°F and particularly suited to
highest temperature applications above 1600°C or 2800°F.
IFB has great features including low thermal conductivity, High
heat resistant and durability, Excellent resistance to thermal
shock, Excellent construction strength and structural integrity,
etc, which enable its capability of dealing with erosive and
abrasive environments. IFB can either deliver big energy savings
for many industrials or offer superior structural performance in
load bearing applications or/and in conditions where mechanical
abrasion exists or flow of hot gases is severe.
KAMTAI Lightweight Mullite Insulating Fire Brick manufactured from
high-grade, high purity refractory materials by mixing,
press-forming, drying, sintering and machining. Good process
providing excellent heat insulation at high temperature and offers
genuine energy savings.
KAMTAI Lightweight Mullite Insulating Fire Brick is well proven
products for solving many problems of heat containment in
industries.Typical applications for IFBs include: lining and back
lining of various furnaces in the industry of metallurgy,
petrochemical, ceramics, machinery and building materials.
Insulating Firebrick (IFB) can be used in applications like:
Cracking Furnace; Conversion Furnace
Heating equipment or Heating Furnace, Even-heating
Mullite insulating bricks characteristics and advantages: 1. Lower
content of iron, alkaline and impurities, good high temperature
properties. 2. Homogeneous structure, light weight, energy saving
because lower heat storage in the furnace during cooling cycles. 3.
High strength, good thermal shock resistance under high
temperature. 4. Precise sizes due to grinding and shaping after
sintering, which meets the requirement of construction. 5. Max
service temp: Up to 1730C (3160F)
