This series products have been developed on the base of low creep bricks,

which are characterized by high thermal shock stability besides low creep.

In 2003,we provided Baosteel Group with over 2300 tons of such 

products for its hot blast furnace(blast furnace 4350m3 in volume) 

and all performance and indexes were proved to exceed the those of 

imported products of the same kind.

Typical technical specification:

1) AL2O3: Min75%

2) Fe2O3: Max1. 0%

3) Apparent porosity: Max21%

4) Bulk density: Min2. 70g/cm3

5)Cold crushing strength: Min70MPa

6) 0. 20MPa RUL: Min1700C
