The Process of high alumina bricks
High alumina bricks are high temperature resistant bricks made from high purity alumina, which is a heat-resistant material. The process of making high alumina bricks involves several stages which are namely raw material preparation, forming, drying, and firing.
In the raw material preparation stage, raw materials such as bauxite, kaolin, or alumina are pulverized to a fine powder. The pulverized powder is then blended in a specific proportion to achieve the desired properties of the final product. The raw materials are then added to a ball mill, where they are mixed with water to form a slurry.
In the forming stage, the slurry is poured into molds of specific sizes and shapes. The molds are then vibrated or compacted to remove any air bubbles and ensure uniform density and strength of the final product.
In the drying stage, the molded bricks are dried at a specific temperature to remove the moisture content. This is important to prevent any cracks or deformation of the bricks during the firing stage.
Finally, in the firing stage, the bricks are fired at high temperatures ranging from 1300°C to 1700°C in a kiln. The firing process is crucial as it helps to strengthen the bricks by sintering the raw materials together. The high temperature also helps to reduce any residual water content and improve the physical properties of the final product.
In conclusion, the process of making high alumina bricks requires several steps that are crucial to the end product’s quality. Raw material preparation, forming, drying, and firing are the stages involved. For the production of high-quality high alumina bricks, it is essential to follow the standard procedures carefully.
How to use high alumina bricks
High alumina bricks are widely used in high temperature and high pressure environments due to their excellent thermal stability, high strength and good corrosion resistance properties. These bricks are made from high-quality bauxite and have an alumina content of above 48%.
One of the major applications of high alumina bricks is in the steel industry. These bricks are used to line the walls of blast furnaces, ladles and tundish in steel plants, which are exposed to extreme temperatures and corrosive environments. The high alumina bricks provide excellent thermal insulation, reducing heat loss and increasing the efficiency of the furnace. Additionally, they have a longer lifespan compared to other refractory materials, reducing the frequency of repairs and maintenance.
High alumina bricks are also used in the cement industry to line the kilns. They are highly resistant to the high temperatures and corrosive materials, preventing the degradation of the lining and prolonging the life of the kiln. The bricks are also used as insulation in boilers, incinerators, and chemical reactors due to their excellent thermal stability and insulation properties.
In conclusion, high alumina bricks have a wide range of applications in industries like steel, cement, and chemical. They provide excellent thermal stability, wear resistance, and strength while withstanding high temperatures and harsh environments. As a result, high alumina bricks give companies a longer lifespan for their equipment and reduced downtime for repairs and maintenance.
