Sintered Mullite with natural high-quality bauxite, through multi-stage homogenization, by more than 1750 DEG C high sintering temperature. Has the advantages of large size, mass, stability, good thermal stability, high temperature creep resistance and good chemical resistance. Is the ideal raw material for the production of various shaped and unshaped refractory materials, advanced sanitary ware body and precision casting model of refractory products.
Mullite is using natural bauxite as raw material, adopt the reasonable process for high temperature lightweight aggregate used in 1400-1500 C. Mullite features: 1, the use of high temperature, can directly contact the working lining using flame, high temperature energy saving. 2, low thermal conductivity, good insulation properties, special lightweight mullite aggregate batching, volume stability, high strength, good airtight structure. 3, weight 40--60%, eliminate hidden broken roof hanging brick. 4, quick drying, high porosity smooth exhaust, shorten oven period, significant economic benefits.
Mullite applications: all kinds of flame furnace lining, direct contact with the flame , insulation and other high-temperature equipment; preparation of various lightweight refractory castable, spray paint; heating furnace, soaking furnace, heat treatment furnace, annealing furnace, ceramic and refractory products sintering furnace and furnace wall; steam boiler petroleum, industrial furnace, ethane cracking furnace lining; various industrial furnace door, observation hole lining.
The natural calcined mullite products using high-quality kaolin as raw materials, processed by high temperature calcination. Products with high quality, high hardness, low expansion coefficient, excellent wear resistance, good thermal stability and so on. Mainly used in metallurgy, building materials, chemical, refractories, military and other industries.
Natural selection of high-quality mullite ore, the advanced industrial furnace and high temperature melting. With the expansion of uniform, excellent thermal shock resistance, high load softening point, high temperature creep value small, high hardness, good resistance to chemical corrosion. Mullite is an ideal material for metallurgy, ceramics, building materials, chemical industry, electric power and casting industry.
With the production of high temperature mullite mullite brick with high temperature, high strength thermal conductivity is small, energy-saving effect is remarkable characteristics, suitable for petroleum cracking furnace, hot blast furnace, metallurgical dielectric ceramic roller kiln, tunnel kiln, shuttle kiln, glass kiln porcelain crucible and furnace lining, can direct contact with the flame.
