High Alumina Brick

High Alumina Brick Introduction:

High alumina brick touts a low iron content, which gives it a high bulk density of the brick thereby increasing its lifespan making it an excellent material for kiln lining brick. High alumina bricks are great in industrial applications where fewer lining changes are preferred. High alumina brick is extremely durable, resistant to friction, and has very a high degree of thermal shock resistance as your furnace heats and cools. Due to its resistance to these phenomena, high alumina brick is less likely to crack, crumble, or otherwise fail for a considerably longer time than conventional fire brick. High alumina brick typically contains between 50-88% alumina, which is more than enough to lend the robust benefits of alumina to the refractory brick.

High Alumina Brick Advantages:

High alumina bricks, It is more heavy than lightweight high alumina bricks. They are not used for thermal insulation, but more importantly for resistance of kiln  temperature. They usually come into direct contact with the flame in the kiln during use, so heavy quality high alumina bricks usually have a high-temperature resistance effect. At the same time, high alumina bricks also have a certain degree of resistance to acid and alkali corrosion, making them widely used in industries such as metallurgy, petroleum, and chemistry.

High Alumina Brick Application:

High Alumina bricks have great features like high temperature performance, great corrosion and wear resistance, high bulk density, low iron content, etc. High Alumina bricks are extensively used in mining, metallurgy, cement, chemical and refinery and refractory industries. These High Alumina bricks – 80% Al₂O₃ can be applied to electric arc furnaces roofs, steel ladles, cement rotary kiln and its cooler, lime kiln, Aluminum melting furnaces, kiln for chemical industry, reheating furnaces and soaking pits, glass tank furnace and regenerator, etc…

high alumina bricks exhibit diverse characteristics. Depending on the production process and raw materials, different manufacturers’ products may vary in color, such as yellow, off-white, and beige. The slight brown spots on the surface add a unique charm to high alumina bricks. High alumina bricks are one of the best-selling refractory materials. These types of bricks are composed of aluminium oxide (Al2O3) at levels typically exceeding 48%, along with other raw materials such as fireclay, and various additives that contribute to their unique properties. High alumina brick is a kind of refractory material, the main component of this kind of refractory brick is AL2O3. The refractoriness of high alumina bricks is higher than that of clay bricks and semi-silica bricks. Belongs to refractory material. There are more Al2O3 in high alumina bricks, which are close to neutral refractory materials, and can resist the erosion of acidic slag and alkaline slag.
