Product Details
Characteristics:
Good thermal stability;
High refractoriness and high softening temperature under load;
Classified into standard bricks, common special-shaped bricks, special-shaped bricks, and extra-special-shaped bricks.
Applications:
High-alumina bricks for hot blast stoves are mainly used in industries such as steel, cement, and non-ferrous metals.It is mainly used for building the linings of ceramic frit kilns, sodium-silicate kilns, glass furnaces, blast furnaces, hot-blast stoves, electric-furnace roofs, cupolas, reverberatory furnaces, and rotary kilns. In addition, high-alumina bricks are also widely used as regenerative checker bricks in open-hearth furnaces, stopper heads in the casting system, and tapping bricks.
