China refractory manufacturer B1 insulating firebrick low density fire clay insulation bricks factory price
Lightweight B1 fireclay insulating firebricks refer to
light-weight thermal insulation brick products with Al2O3 content
of 30%-46%. With clay clinker or light clinker and plastic clay as
the main principle, it is usually produced by the combustible
method. It can also be produced by the chemical method or foam
method to form a porous structure. The use temperature is
1200-1400℃. The refractory is characterized by high porosity,
generally 40%-85%; low bulk density below 1.5g/cm3; low thermal
conductivity, generally below 1.0W (m.K).
Compared with ordinary fire clay bricks, light clay bricks are
lighter in weight. The heat-insulating refractory products with
Al2O3 content of 30%~48% made of refractory clay as the main raw
material. Using refractory clay, floating beads, and refractory
clay clinker as raw materials, adding binders and sawdust, after
batching, mixing, molding, drying and firing, products with a bulk
density of 0.3~1.5g/cm3 can be obtained. It accounts for more than
half of the total output of heat-insulating refractory bricks, with
tiny pores evenly distributed inside, with a high porosity.
Therefore, it can be ensured that the furnace wall loses less heat,
and the fuel cost will be reduced accordingly. Lightweight clay
bricks also mean less heat storage, so heating and cooling are
faster, allowing faster periodic operations. Lightweight clay
refractory bricks are suitable for the temperature range of
900℃~1650℃.
Lightweight B1 fireclay insulating firebricks have the
following characteristics:
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. High refractoriness and high aluminum content make it maintain
good performance in 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. Can be processed into special shapes. In order to reduce the
number of bricks and joints.
We usually use light weight fire clay insulation bricks in the
thermal insulation of industrial kilns, which can reduce the heat
loss of the kiln, save energy consumption, and reduce the quality
of thermal equipment. However, lightweight clay bricks have poor
mechanical strength, wear resistance and slag erosion resistance,
and are not suitable for the load-bearing structure of kilns and
parts that directly contact slag, charge, molten metal, etc.
Therefore, in kilns where the demand for refractory materials is
not high, we can choose cheap lightweight clay bricks for thermal
insulation, which is very cost-effective.
