White mullite lightweight refractory fire brick with good thermal
storage
1. Description
high heat resistant insulation 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 chemical demands.
The total weight of the furnace body and walls thickness can be
reduced effectively,thermal efficiency and working condition can be
improved,energy consumption can be lowered,produtivity and
significant economic results can be achieved.
It 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.
2. Features
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)
3. Application:
1. Carbon bake furnaces in the aluminum industry
2. Preheat zones and cyclones of rotary cement kilns
3. Insulation for glass tanks
4. Fireplace and pizza ovens
5. Coke ovens
6. Blast furnaces
7. Reheating furnaces
8. Suspended roofs
9. Lime kilns
10. Chimney
