| Phosphoric acid immersed fireclay brick for blast furnace |
Phosphoric acid immersed fireclay brick for blast furnace: Phosphoric acid immersed fireclay bricks are the fire-resistant fireclay products which are made from the bauxite clinker and phosphoric acid or aluminum phosphate. Phosphoric acid immersed fireclay brick is immersed by the phosphoric acid at low-temperature after high-temperature firing, mainly used in the central body and the cooling wall of the large-scale blast furnaces.
