1,Description of High Alumina Cordierite Brick
The main raw materials of high alumina cordierite bricks are synthetic cordierite, bauxite clinker, flint clay and high-quality clay, which are prepared by scientific particle grading, high-pressure molding and high-temperature firing. High alumina cordierite brick is superior to ordinary high alumina brick in thermal shock resistance and spalling resistance. It is not easy to crack in the process of use, has good stability, good resistance to flue gas brushing and corrosion, and has low heat storage capacity. It is often used in hot blast furnace pipes, kiln car bricks, tool bricks, etc., with good use effect.
