Product Description
High-alumina bricks are made of bauxite clinker as raw material, adding a certain amount of bonded clay, and an aluminum-silicon refractory product with an Al2O3 content of more than 48%. The production process of high-alumina bricks is basically the same as that of high-quality multi-stubble clay bricks. The difference is that there is a classification and sorting process before clinker crushing and a post-screening iron removal process.
High-alumina bricks change the ratio of Al2O3/SiO2 on the basis of clay bricks and increase the content of Al2O3, so the refractoriness and high-temperature mechanical strength are better than clay bricks. The chemical properties of high alumina bricks tend to be neutral, so they are more resistant to acid and alkali slag erosion than clay bricks and silica bricks.
Therefore, the parts that used silica bricks or clay bricks in various thermal equipment can be replaced by high alumina bricks. Using high alumina bricks instead of clay bricks and silica bricks can improve the service life of thermal equipment.But high alumina bricks are more expensive than clay bricks. Therefore, it is not necessary to use high alumina bricks where clay bricks can meet production requirements.
