Acid And Alkali Resistant Al203 High Alumina Bricks With High Refractoriness and Heat Shock Resistance
Features of Acid And Alkali Resistant Al203 High Alumina Bricks
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.
