Product Description

Light Weight Mullite Insulation Brick:

The light weight mullite insulation brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.

Light Weight mullite Brick Feature:

1. Low bulk density, low thermal conductivity, good thermal insulation performance.
2. Refractory category allow direct contact of fire, suitable ofr various atmosphere
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely
4. Product specification: standard form, normal standard, shaped and special shaped bricks.
5. Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the most widely used.


Light Weight Mullite Insulation Brick Applications:

1. Furnaces of metallurgy industry, heat treatment furnace
2. Furnaces of chemical industry and construction industry.
3. Furnace of incineration of garbage, recirculating fluidized bed furnace


Performance and application of Mullite Insulating Firebrick:

The refractoriness is high, can reach to more than 1790 degrees centigrade. The RUL is 1600~1700 degrees C. The compressive strength at normal temperature is 70 ~ 260MPa. The thermal shock resistance is good. There are two kinds of mullite bricks: sinterted mullite and fused mullite brick.

The Characteristics of Mullite Insulating Firebrick:

The main material of sintered mullite brick is high alumina bauxite as the main raw material, adding a small amount of clay or raw bauxite as binder, it is made by molding and sintering. Fused mullite brick with high bauxite, commercial alumina and refractory clay as raw material, adding charcoal or coke fines as a reducing agent, after molding, can adopt the reduction electrofusion method to manufacture. The crystallization of the electric cast mullite is larger than that of the sintered mullite, and the thermal shock resistance is better than that of the sintered product. Their high temperature performance mainly depends on the content of alumina oxide and the uniformity of the distribution of mullite and glass.
