Sintered microporous alumina carbon brick not only has excellent alkali corrosion resistance and titanium slag corrosion resistance, but also non-wetting with slag and high-temperature molten
liquid. What is more, it have excellent thermal shock resistance, high strength and excellent oxidation resistance.
Physical properties of Sintered microporous alumina carbon brick:
High temperature resistance: Able to withstand extremely high temperatures, usually used in environments exceeding 1600°C.
Excellent corrosion resistance: Has good chemical corrosion resistance, especially resistance to molten metal and furnace gas.
Good thermal stability: Able to maintain stable physical and chemical properties in high temperature environments.
Low thermal conductivity: The microporous structure effectively reduces thermal conductivity and improves thermal insulation performance.
High mechanical strength: Maintains strong wear resistance and compressive strength even in high temperature environments.

Main applications of Sintered microporous alumina carbon brick:
Sintered microporous aluminum carbon bricks are mainly used in high-temperature industrial kilns, including:
Electric arc furnace: Used for steel smelting, especially electric arc furnaces operating at high temperatures.
Ladle: In the steel production process, it is used for ladle lining to improve the fire resistance and service life of the furnace lining.
Other high temperature furnaces: such as aluminum melting furnaces, glass melting furnaces and other applications that require high temperature resistance and corrosion resistance.
The characteristics of these bricks make them very suitable for industrial kilns that require high temperature refractory and long-term stable performance.
