Mullite corundum packing mass

Description of mullite-corundum packing material

Mullite-corundum packing is a high-performance non-formed refractory material with mullite and corundum as main components. It has advantages such as high heat resistance (1800℃), heat resistance, corrosion resistance, high strength, etc. It has a packing material design and is suitable for high temperature vulnerable parts such as metallurgical furnaces, glass and ceramic furnaces, chemical equipment such as iron chute of blast furnace, ladle lining, etc.
