1.Product description of Alumina corundum mullite bricks
Mullite brick is a high-quality aluminum refractory product, with the alumina content of about 65%~75%. Mullite bricks are mainly made of mullite, which are fired at high temperature and formed under high pressure. Mullite brick has the advantages of high temperature resistance, chemical and mechanical corrosion resistance, thermal shock resistance, etc.
2. Application of Alumina corundum mullite bricks
Because of its excellent characteristics, alumina corundum mullite bricks are often used in petrochemical industrial furnaces, gasifiers, large-scale fertilizer equipment, and ultra-high temperature furnaces and linings above 1600 ℃.
