Question:

What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?

Answer:

You can use ceramic fiber module
Yes, but the cost is high, refractory material should be the most affordable at present.
The price is high, but the the service life is not longer than the clay brick, some use high aluminia brick. Currently, there are no refractory products that can replace refractory bricks. The effect is good of choosing fireclay brick with high strength dense, low porosity clay brick. We have maken several lines of refractory bricks. Actually, if you choose good refractory brick, the service life will be very long. The kiln temperature is not high.
