Product Description
Description of Factory Price High Quality Standard Size High Alumina Refractory Fire Brick
High-alumina bricks refer to aluminum silicate refractory products with alumina (Al2O3) content greater than 48%. According to the Al2O3content, they can be divided into groups of 48%, 55%, 65%, 75%, etc. High-alumina bricks for steel-making electric furnace roof can be divided into groups of 65%, 75%, 80%, etc. According to the application, they can be divided into high-alumina bricks for blast furnace, high-alumina bricks for electric furnace roof, high-aluminum bricks for hot blast stove, high-alumina bricks for teeming ladle, high-alumina bricks for ingot casting, general high-alumina brick, etc. The raw materials for producing high-alumina bricks are mainly high bauxite, kyanite, andalusite, sillimanite, natural corundum, industrial alumina, etc. The production process is adding an appropriate amount of binders (for example, clay) into the raw materials, mixing evenly, dry pressing to form, and firing at high temperatures.
