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.
Fused mullite is made of high-purity quartz sand and industrial alumina, melted in super large electric arc furnace, and can be processed into particles, fine powders and micro powders with different sizes. It has white color, low carbon residue and well-developed acicular crystals. With the characteristics of low porosity, low impurity content, and good thermal shock resistance and wear resistance. It is widely used in glass kiln lining brick, alkali free glass sedimentation tank, hot blast stove brick of large smelting blast furnace, low creep sillimanite brick of blast furnace, ceramic kiln furniture, box antimony, shed plate, petrochemical industry and other industries.
High purity, White color. Alumina based Sintered Mullite is made of high-quality alumina powder by special process and sintered at high temperature. The product has the characteristics of high fire resistance, good resistance to chemical corrosion and good thermal vibration stability, which is widely used in iron and steel smelting, ceramics, building materials, chemical industry, nonferrous smelting and other industries.
