Description

technical field [0001] The invention relates to a process for manufacturing mullite-corundum series large-scale, special-shaped sintered refractory products by adopting advanced amorphous material technology, which has the characteristics of easy forming, easy sintering and good high temperature performance, and the produced products can be used as kiln furniture , large bricks and other products are used in high temperature industries such as ceramics and glass. Background technique [0002] Mullite-corundum material is a widely used refractory material. Among them, mullite endows the material with excellent high temperature mechanical properties and certain thermal shock resistance; corundum endows the material with high temperature resistance and wear resistance. Occasionally, some zirconia can be added to the material to improve thermal shock resistance. In order to reduce the firing shrinkage, three stones (andalusite, sillimanite and kyanite) can also be used to part...
