High alumina refractory bricks

Product Details

High alumina brick is a refractory material, the main component of which is alumina (Al₂O₃). Due to its high aluminum content, high alumina brick has high refractoriness and good high temperature resistance.

LMM GROUP high alumina refractory bricks are widely used in the steel industry, mainly in the following aspects:

Blast furnace lining: High alumina bricks are often used in the hearth, belly, body and roof of blast furnaces, which can effectively resist the erosion of high-temperature molten metal and slag, and extend the service life of blast furnaces.

Converter and electric furnace lining: In the lining of converters and electric furnaces, high alumina bricks can withstand the erosion of high-temperature molten steel and slag, ensuring the stability and durability of the lining.

Ladle and tundish lining: High alumina bricks are used for the lining of ladles and tundishes, which can maintain good refractory properties during the pouring of molten steel, avoid direct contact between molten steel and lining, reduce the impurity content in molten steel, and improve the purity of molten steel.

Heating furnace and heat treatment furnace lining: High alumina bricks are also widely used in heating furnaces and heat treatment furnaces. They can withstand high temperatures and frequent temperature changes, and maintain the integrity and stability of the furnace lining.
