Product Description

Low porosity clay brick

Characters of Low porosity clay brick
 
With the continuous development of smelting technology, the standard requirement of refractory bricks used for hot metal ladle is higher and higher. The service life is not long for with general used clay brick, so low porosity clay brick has become the mainstream of refractory material products now.
Low porosity clay brick has a variety of standards. There are mainly three standards: Three low clay brick(DDD), low porosity clay brick (DN-12,DN-15)  common clay brick ( N-1,N-2a), 

Applications of Low porosity clay brick

Widely used in glass furnace, blast furnace, hot blast furnace, cement kiln, chemical kiln and other thermal technology equipment.
