General Information

Our silicon insulation brick is made of baked crystalline silica as raw material by adding into compound flammable substance. This product has low thermal conductivity, high refractoriness
under load, residual expansion trace, excellent variability of re-burning line and other characteristics, which is widely available for heat-insulating layer of various high-temperature furnace equipments not in contact with molten slag under high temperature condition (≤1,500 ℃).

With dense and smooth appearance, uniform corner and edge, pure color and luster and accurate size.

1) Silicon oxide is above 95%.
2) Good acid erosion resistance.
3) High softening point with temperature.
4) No shrink in burn repeatedly.
5) Temperature of refractoriness under load is above 1650º C

Typical Application
Light- weight Insulating Brick can be used as a hot surface or other refractory refractory insulation support, used for melting furnace, ignition furnace, flue, refining equipment, heating equipment and piping, regeneration device, gas furnace, soaking furnace, annealing furnace, heat reaction chamber and other industrial equipment.

Advantage of Insulating Brick
Light- weight Insulating Bricks are made from refractory clay as the main raw material of the AL2O3 content is 30% ~ 48% of the heat insulation refractory brick. The production process adopts the burn out of character and bubble method. With refractory clay, drift beads, refractory clay clinker as raw material, adding binder and sawdust, the ingredients, mixing, molding, drying, firing, volume density was 0.8 to 1.5 g/cm3.

$Refractory Silica Insulation Fire Brick$

Q: Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.: Classification of chemical components of refractory materialsAccording to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.

Q: The hot blast stove when the temperature did not rise against the brick interface decreased: How to keep the brick masonry temperature not lower than 600 DEG C, while the exhaust temperature is not higher than 400 DEG C.

Q: The difference between clay refractory bricks and refractory brick in the application.: The ability of alkali resistance is poor, the thermal shock stability is the worst, and it is scrapped at one time. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.

Q: Such purpose and scope please give me detailed points thank you because I am learning stage: Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.

Q: What is the main material of silica brickIt's common, the kind we see so often!: Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into phosphorus and quartz. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.

Q: Semisilica brick, clay brick, high alumina brick and what is the difference?: This is a kind of refractory material is divided into three types: semisilica brick (A12O315 ~ 30%), clay brick (A12O330 ~ 48%), high aluminum brick (A12O3>48%).

Q: What role does silica play in refractories?: The production of clay brick refractory clay raw material is natural, its main mineral is kaolinite (formula Al2O3 - 2SiO2 - 2H2O), clay brick containing SiO2 in 45% ~ 65%, belongs to the weak acid refractory materials, have a certain ability to resist acid slag, but easy to be alkaline slag erosion.

Q: The brick is mainly used in the place?: Open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts.

Q: Can iron oxide be used as refractory material?: Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment

Q: Physical solid waste disposal: Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products when firing, reduce cracks, improve the rate of finished products.
