Description of Rongsheng Refractory Brick High Alumina Lining Bricks With High Refractoriness For Hot Blast Stove
High Alumina Refractory Brick is a type of refractory material with an alumina (Al2O3) content of more than 48%. It is a dense, hard brick with excellent resistance to high temperatures, corrosion, and abrasion. High Alumina Refractory Brick is typically used in applications where temperatures exceed 1850°C (3362°F).
High Alumina Refractory Brick is an essential material for many industrial processes. It is known for its durability, reliability, and performance in high-temperature and corrosive environments.
