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: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:Which material is good for furnace refractory?: Kiln types of refractories is very extensive, selection of refractory materials according to the type of furnace furnace temperature and use of selected refractory material, refractory material is divided into custom products of refractory bricks and unshaped refractory castable series products. According to chemistry, it is divided into acidic, neutral and alkaline materials.

Q:Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450: That is because the brick load softening point the maximum temperature is 1450 degrees.

Q:What role does silica play in refractories?: Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.

Q:Such purpose and scope please give me detailed points thank you because I am learning stage: Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.

Q:Glass kiln brick for physical and chemical indicators?: Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.

Q:The difference between clay refractory bricks and refractory brick in the application.: Clay brick features good thermal shock resistance and low price, but high temperature performance is not well integrated, and the long-term use temperature is not higher than 1300 degrees. It is widely used in low temperature parts of various kilns.

Q:What are the main constituents of refractory bricks?: Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon, aluminum, clay and so on:

Q:Common bond brick?: Manufacturing for silica brick binder hi-li sulfate pulp waste liquid and lime milk. When lime milk is used as a bond, it acts as a plasticizer. To increase the strength of lime brick in the drying process, as mineralizer in the firing, promote the transformation of quartz.
