High Aluminum Bricks for Blast Furnace

High-alumina brick is a refractory material that is widely used in the lining of blast furnaces. It is made from high-purity bauxite and high-purity quartz sand sintered at high temperatures. High-alumina bricks have excellent fire resistance and can withstand high temperatures, high pressures and chemical attack in the furnace environment.

The main characteristics of high-alumina bricks are high strength, high-temperature stability and corrosion resistance. Its high strength can ensure the stability and safety of the internal structure of the blast furnace, while the high temperature stability can resist the erosion of the environment in the high-temperature furnace and maintain its good performance. At the same time, high-alumina bricks can also resist the erosion of slag and molten iron, prolonging the service life of the blast furnace.

High alumina bricks have excellent heat conductivity and wear resistance, can effectively conduct heat in the furnace, and are not easy to wear at high temperatures. This makes high-alumina bricks widely used in the wall, bottom and top of blast furnaces. The use of high-alumina bricks can improve the production efficiency and heat utilization rate of the blast furnace, reduce energy consumption, and is of great significance to ensure the normal operation of the blast furnace.

In short, high-alumina brick is one of the important refractory materials of blast furnace, and its excellent performance and stability can meet the needs of the extreme environment inside the blast furnace and ensure the normal operation and long-term stability of the blast furnace.
