High Alumina Brick

High alumina brick is one of the most extensively used and abundantly produced refractory products in the field of refractory materials. Its widespread applicability spans across various industries including metallurgy, construction materials, environmental protection, power generation, and glass production. This versatile refractory material is particularly well-suited for different furnace linings. Its optimal performance is observed at elevated temperatures ranging from 1250 to 1500°C.

High alumina brick is made of bauxite clinker and bonded clay as main raw materials, sintered at intermediate temperature. High aluminum brick is a neutral refractory material, acid and alkaline slag have a certain corrosion resistance, but has good thermal shock stability and load softening temperature, in the high temperature industrial kiln is more widely used, in the RH furnace is mainly used for the upper groove and hot bend pipe permanent lining.

What Field is High Alumina Brick Suitable for?

High alumina bricks are primarily composed of materials such as calcined bauxite. These materials undergo processes including high-temperature blending, shaping, drying, and sintering. The aluminum oxide content in high alumina bricks varies based on proportions. Typically, the content ranges between 48% and 80%, with the highest aluminum oxide content reaching up to 90%. These bricks boast a remarkable refractory temperature of up to 1770°C.

High alumina bricks find versatile application in various industries: Iron and Steel Manufacturing: Blast furnaces, hot blast stoves, electric furnaces, ladles, ladle covers, heating furnaces, refining furnaces, reheating furnaces, annealing furnaces, and cupolas. Non-Ferrous Metal Industry: Smelting furnaces, refining furnaces, reverbatory furnaces, and converters. Construction Materials Sector: Cement kilns, glass kilns, ceramic kilns, lime kilns, kiln cars, and tunnel kilns. Energy and Incineration: Coke ovens, circulating fluidized bed boilers, carbonization furnaces, and incinerators.
