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,it passed the technical verification organized by Science and Technology Bureau of Henan Provincial Government and was evaluated as holding the international leading level.In the same year,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)Model:WH21
2)AL2O3:Min75%
3)Fe2O3:Max1.0%
4)Apparent porosity:Max21%
5)Bulk density:Min2.70g/cm36)Cold crushing strength:Min70MPa
7)0.20MPa RUL:Min1700C
