JM23-30 mullite lightweight insulation refractory fire brick for
glass fusing kiln
Lightweight mullite refractory bricks are made from good quality
and superpure raw materials, with strictly classified fillings
according to their grades. These fillings can form a uniform pore
structure after burnt during the process of manufacture. Each grade
of products has unique design to meet different thermal, physical
and chomical demands.
The refractory linings of hot surfaces or backing heat-insulating
layers of other refractory materials. The refractory linings or
heat-insulating materials of the industries, such as, ethylene
pyrolysis furnaces, tubular furnaces, reforming furnaces of
synthetic ammonia, gas generators and high-temperature shullte
Mullite Lightweight Bricks are primarily used for lining of the
shuttle kiln for calcining refractory material, industrial ceramics
, domestic ceramics and the bricks for the high temperature zone of
tunnel kiln, insulation fire bricks for high-temperature furnace.

Characteristics of our Mullite Insulation Fire Brick IFB(JM-IFB):
1) After shaping and sintering, cutting and grinding processing are
done, drilling is necessary according to brick drawings.
2) Little impurities of iron and alkali metal
3) High temperature resistance
4) uniform structure and high cold crushing strength
5) Good thermal shock resistance, stable volume, good insulation
performance in high temperature
6) Low thermal conductivity
1. The Mullite Insulating Fire Brick will be packed as the standard
of exporting or packed on wooden pallet with three layers
water-proof shrink film and tightened with plastic/steel
bandages,when in the transportation process,we should pay attention
to moisture-proof and light handling.
2. The packing of Refractory Brick will accept customer's
requirement if any.
3. Delivery within 10-15 working days after your payment.
4. Fast delievery accepted by customers.
