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
