Light weight glass blocks refractory mullite brick for fireplace lining
We call the high alumina refractory with mullite as the main crystalline phase mullite brick, divided into heavy brick and light brick. Generally, the alumina content is between 65% and 75%. In addition to mullite, the lower alumina also contains a small amount of glass phase and calcite. The higher alumina content also contains a small amount of corundum. Different types of bricks have different production techniques and application.
Heavy mullite brick:
Refractory bricks made from sintered or fused mullite may be made
entirely from mullite, or partly from mullite and partly from
corundum. The former is called mullite brick, the latter corundum
one-mullite brick or mullite one-corundum brick. The production
process of mullite brick is the same as that of high alumina brick.
The firing temperature is related to the composition of
ingredients, the purity of raw materials and the requirements on
the properties of bricks, usually 1500 ~ 1700℃. The crystallization
of fused mullite brick is larger than that of sintered mullite
brick and the thermal shock resistance is better than that of
sintered mullite brick. Advantages are: high fire resistance, up to
1790℃ above, load softening temperature 1600-1700℃, room
temperature compressive strength 70-260mpa, excellent thermal shock
resistance. It is mainly used in hot blast furnace top, blast
furnace body and bottom, glass melting furnace regenerator, ceramic
sintering furnace, dead corner lining of petroleum cracking system,
etc.
Light mullite brick:
Mullite light insulation brick is made of high quality high purity
refractory, high alumina clinker as raw material according to the
specific gravity of the product, adding organic composite filler,
after vacuum extrusion, high temperature sintering synthesis of
light mullite products. By virtue of its light weight and excellent
thermal insulation performance, mullite light thermal insulation
brick is widely used in a variety of thermal surface refractory
lining or insulation layer, to improve the energy efficiency of
equipment.
Product Advantages:
1. Low heat conduction and low heat capacity
2. High purity and low impurity content
3. High temperature resistance and direct contact with flame
4. High strength and heat shock resistance
Lightweight Mullite brick application: various industrial furnace
hot face fabrics and backings in metallurgy, petrochemical,
building materials, ceramics, machinery and other industries.
