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.

- Q:What is the main material of silica brickIt's common, the kind we see so often!
- More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance.
- Q:Which material is good for furnace refractory?
- Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.
- Q:Physical solid waste disposal
- Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
- Q:The chemical composition of silica brick and its physicochemical index?
- Brick refers to the refractory products in more than 93% of the content of SiO2
- Q:The introduction of silica brick
- The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass
- Q:What are the main constituents of refractory bricks?
- (a) containing refractory brick brick, refers to more than SiO293%, is the main varieties of acid resistant brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.
- 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.
- Q:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you
- The main damage of silicon carbide side wall brick is stress damage, not chemical erosion. Chemical damage is formed prior to the formation of the groove, and the damage to the chemical erosion is little after the formation of the groove.
- Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
- Mainly from the impurities to determine how much, generally less impurity single color brick.
- Q:Semisilica brick interpretation
- High temperature volume stability. Volume change is small.
