High alumina bricks are used in a variety of industries, including:
1.Metal casting: High alumina bricks are used to line the runners
and gates of casting molds, as well as to form the crucibles in
which molten metal is poured.
2.Glassmaking: High alumina bricks are used to line glass furnaces
and to form the molds in which glass is poured.
3.Cement production: High alumina bricks are used to line cement
kilns and to form the molds in which cement clinker is cooled.
4.Petrochemicals: High alumina bricks are used to line reactors and
other equipment in petrochemical plants.
5.Metal refining: High alumina bricks are used to line furnaces and
other equipment in metal refining plants.
Power generation: High alumina bricks are used to line the boilers
and furnaces of power plants.
