The application scope of corundum mullite brick is becoming more and more common, and the praise is becoming higher and higher. We should pay special attention to the appropriate operation steps when we carry out the simple installation, so that we can better apply it. Let's get familiar with the production and manufacturing raw materials of corundum mullite brick.

The raw materials for the production and manufacture of corundum mullite bricks are mainly divided into fire-proof products with kyanite as the key raw material, because many microporous plates are generated in the middle of the particle frame of Kyanite in the whole process of dissolution and swelling. For fire protection products that immediately touch the solution, the appearance of this microplate will reduce its adhesion resistance. The lightweight zirconium corundum brick is the lining of a high-temperature industrial kiln that does not touch the solution. It is not only required to have high application temperature, but also must have low heat transfer coefficient. For general lightweight refractories, in a certain range, the smaller the porosity specification, the lower the heat transfer coefficient. Therefore, the microporosity established by the dissolution of Kyanite is just a resource advantage to improve the fire resistance of light zirconia corundum brick.

Corundum mullite brick has the characteristics of high temperature, low specific heat, low heat transfer coefficient, high compressive strength, good heat resistance and shock resistance. The lightweight zirconium corundum brick with Al2O3 content of 67.1% produced by Kyanite and industrial production of aluminum oxide powder is mainly used in various industrial kilns of daily porcelain, building ceramics and special ceramic molds, various high-temperature industrial kilns in the field of petrochemical equipment, various heat treatment furnaces in the industry and large and medium-sized hot blast boilers for immediate fire lining. In this kind of industrial kiln, when the operating temperature exceeds the temperature that other light-weight raw materials can bear, it is necessary to make full use of the various characteristics of this kind of light-weight silica brick where building raw materials are used.
