Advantages of Kerui Jm28 Insulation Brick
Low Thermal Conductivity
It has a good thermal insulation effect. Due to the low thermal conductivity, JM28 insulation bricks accumulate very little heat. Its energy-saving effect is more obvious in the intermittent operation of the kiln.
Low Impurity Content
Therefore, its refractoriness is high. Moreover, the higher aluminum content enables it to maintain good performance under reducing atmosphere.
Standard Appearance Size
This increases the masonry speed and reduces the use of refractory mud. In addition, Kerui Jjm28 insulating fire brick also ensures the strength and stability of the masonry, thereby extending the life of the lining.
Customized Special-Shaped Bricks
We can process them into special-shaped insulation bricks according to customer needs. This can also reduce the number of bricks and masonry joints.
JM28 Insulation Brick for Masonry Kilns
JM28 insulation bricks are used for the lining and insulation layer of masonry kilns. The kilns it is used in are as follows:
- High temperature shuttle kiln;
- Ceramic roller kiln;
- Push plate kiln;
- Gas generator;
- Ethylene cracking furnace;
- Tube heating furnace;
- Synthetic ammonia converter;
- ……
