Industrial Insulating Refractory Fire Bricks For High Pure Ceramic Precise Sizes


lightweight mullite insulating refractory fire brick for ceramic industry


1. Description

Mullite insulating brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature.

Classified by working temperature, there are JM-23,JM-26,JM-28, JM30, JM32.

These products can directly contact with fire, characterized with high temperature resistance, lightweight, low thermal conductivity, good energy saving effect,

specially suitable for cracking furnace, hot blast furnace, ceramic roller kiln, porcelain kiln extraction, glass crucible and various electric furnaces as lining.

It is an ideal product of energy efficiency and longevity.


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
