High Alumina Brick is a shaped refractory brick manufactured by high-temperature firing of bauxite and other high-alumina raw materials. It is classified by Al₂O₃ content, widely used in various high-temperature industrial furnaces. It differs from fire clay brick with higher alumina content and better high-temperature performance.

Key Features：

-High refractoriness, excellent high-temperature strength and good thermal load resistance.

-Strong slag corrosion resistance, suitable for acidic and partial alkaline working environments.

-Good volume stability at high temperature, low linear expansion rate.

-Stable physical properties, long service life in kiln linings.

-Multiple grades available to match different temperature and working conditions.

Available Grades：

LA40: Al₂O₃ ≥40% LA50: Al₂O₃ ≥50% LA60: Al₂O₃ ≥60% LA70: Al₂O₃ ≥70% LA80: Al₂O₃ ≥80%

Main Applications：

-Lining for cement rotary kilns, lime kilns, tunnel kilns and heating furnaces.

-Industrial boiler, hot blast stove, glass kiln and incinerator lining.

-Steel industry ladle, tundish and heat treatment furnace linings.

-Non-ferrous metal smelting furnaces and ceramic kilns.
