The fireclay brick for tunnel kiln is used in high temperature insulation layer of tunnel kiln that has high refractoriness 

and good thermal shock resistance. 

 

High quality of firecaly bricks for tunnel kiln can be used as the linings that directly contact the fire however it can not

be used in the place where eroded by slag directly. Because the firecaly brick is of good stability under reduction 

condition it is widely used as the inner insulation layer in the tunnel kiln that protected by hydrogen or carbon

monoxide atmosphere.
