Introduction of mullite Mullite is a kind of high quality refractory materials, it has a uniform expansion, hot pillow excellent stability, high load softening point, high temperature creep value is small, high hardness, good resistance to chemical corrosion, there are mainly high purity fused mullite, fused mullite sintered mullite, all natural bauxite concentrate and light mullite. Mullite purposes Mullite are suitable for all kinds of flame furnace lining work, direct contact information with the flame (not contact information melt), other high temperature heat preservation and heat insulation equipment, such as: 1, the preparation of various lightweight refractory castable, spray coating, etc.; 2, heating furnace, soaking furnace, heat treatment furnace, annealing furnace, ceramic, refractory products sintering furnace, the furnace wall; 3, steam boiler, oil industry tube furnace, ethane cracking furnace lining; 4, all kinds of industrial furnace door, observation hole lining.
