Henan Hongtai refractory brick manufacturer JM23 JM26 JM28 Light Weight mullite Insulation brick for Furnace Insulation
Light weight Mullite insulation brick is a kind of quality refractory insulation materials for resisting high temperature with features of light weight, low thermal conductivity, thermal insulation and high compression strength in the high temperature furnaces or kilns. lightweight bricks are mainly used for the top of hot blast stove, stack and bottom of blast furnace, regenerative chamber of glass melting furnace, lining of ceramic high temperature furnace and so on.
Light weight Mullite insulation brick is manufactured with mullite as the main crystal phase and contains about 65~75% alumina content. Mullite Insulation Brick has high refractoriness that reaches up to 1790 ℃. Its apparent initial softening temperature is about 1600~1700℃. Its cold crushing strength is about 70~260MPa. Mullite Insulation Brick can be classified into different types of 1350 lightweight brick, 1450 lightweight brick and 1550 lightweight brick according to different service temperature and into Lightweight Mullite Brick and Heavy Mullite Brick according to different bulk density.
Lightweight Mullite Insulation Bricks Features:
1. Low thermal conductivity, with good thermal insulation effect;
2. Low thermal melting, due to low thermal conductivity, the
mullite series of lightweight insulation bricks accumulate little
heat energy, and the energy saving effect is obvious in
intermittent operation; 3. Low impurity content has very low iron
box alkali metal and other oxide content, therefore, high
refractoriness; high aluminum content makes it maintain good
performance in a reducing atmosphere; 4. High compressive strength
in hot state; 5. Accurate appearance and size, speed up the
masonry, reduce the amount of refractory mud, ensure the strength
and stability of the masonry, thereby extending the life of the
lining; 6. It can be processed into special shapes to reduce the
number of bricks and joints. It can be directly used for the lining
of high-temperature kilns, and has been widely used in shuttle
kilns, roller kilns, glass and petrochemical kilns.

JM23 JM26 JM28 Light Weight mullite Insulation brick for Furnace Insulation
Light weight mullite insulation brick Application
Lightweight mullite insulation bricks are widely used in various kiln linings, thermal insulation layers and thermal insulation layers in metallurgy, machinery, ceramics, chemical and other industries. The use temperature is 1300-1600 ℃, which is an ideal energy-saving product.
At present, most of the high temperature resistant materials used in kilns use lightweight bricks as masonry materials, which can reduce the weight by about twice. Save the cost of building kilns and save raw materials: to achieve the same use temperature and effect.
can be directly contact with the flame,this insulating brick can be used as linings or thermal preservation layers in various industrial furnaces and kilns in metallurgical industry, ceramic industry, chemical industry, machinery industry, such as blast furnace, hot blast stoves ,electric arc furnace, cement kiln,melting furnace, ignition furnace, flue, refining equipment, heating equipment and piping, regeneration device, gas furnace, soaking furnace, annealing furnace, heat reaction chamber and other thermal industrial equipment.
Light weight mullite insulation bricks can be used as hot surface refractories or other refractory materials to support thermal insulation, used in melting furnaces, ignition kilns, flues, refining devices, heating devices, regeneration devices, gas furnaces and pipes, soaking furnaces, Annealing furnaces, reaction chambers and other industrial thermal equipment.
