Refractory Manufacturer fireplace silica brick refractory for wood stove high density silica insulating fire bricks refer to heat-insulating refractory products made of silica as the main raw material and with an SiO2 content of not less than 91%. In addition to the thermal insulation properties of Insulating silica bricks, Refractory Manufacturer fireplace silica brick refractory for wood stove high density silica insulating fire bricks maintains the characteristics of silicon bricks to a large extent. The starting temperature of load softening is high, and the volume expands slightly during the heating process, which enhances the integrity of the kiln. The manufacture of siliceous Insulating silica bricks uses finely pulverized silica as the raw material, adding part of the waste silica bricks or waste siliceous Insulating silica bricks powder, mineralizers and burnout additives. Add water to the mixer according to a certain proportion to mix into a mud, which is formed by mechanical or manual molding. After the brick is dried, the residual moisture is less than 0.5% before Refractory Manufacturer fireplace silica brick refractory for wood stove high density silica insulating fire bricks can be loaded into the kiln. In order to prevent the violent volume expansion due to the polycrystalline transformation of SiO2, causing cracks in the product, a slower temperature rise and fall speed are required during firing.

 

Refractory Manufacturer fireplace silica brick refractory for wood stove high density silica insulating fire bricks generally use crystalline quartzite or silica sand as raw materials, and the mineral composition is: phosphorite 78% to 86%, cristobalite 13% to 15%, and quartz 4% to 7%. Add combustible materials to the ingredients, such as coke, sawdust, anthracite, carbonized rice husk, or use gas foaming to form a porous structure. Refractory Manufacturer fireplace silica brick refractory for wood stove high density silica insulating fire bricks Price are heat-insulating silicon refractory products with a SiO2 content of more than 90% and a bulk density of less than 1.2. The refractoriness and softening temperature under load are not much different from ordinary silica bricks with the same composition. However, due to the many pores, the compressive strength, slag resistance, and corrosion resistance are not as good as ordinary silica bricks, but the thermal shock resistance has been improved. Refractory Manufacturer fireplace silica brick refractory for wood stove high density silica insulating fire bricks is similar to the production process of ordinary silica bricks. Some mineralizers (CaO, Fe2O3) are added to the ingredients to promote the conversion of quartz, and pulp waste liquid is used as a binder to make the bricks have a certain strength. When using coke or anthracite as combustible additives, because the ash will be brought into Fe2O3 and Al2O3, there is no need to add iron scales in the ingredients. When the siliceous Insulating silica bricks are fired, a strong oxidizing flame should be maintained before 1200°C to make the additions burn out completely.

Advantage:

 

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
Stable Capability, High Quality, Excellent Service, Competitive price is the most important advantage of our products.

 

Application:

 

    Refractory Manufacturer fireplace silica brick refractory for wood stove high density silica insulating fire bricks​​ are used in the blast furnace blast area and communicate with the blast furnace exhaust. The light silicon bricks have a temperature range of 1000 ~ 1300 ℃. Can meet the whole cycle life of hot blast stove


   Refractory Manufacturer fireplace silica brick refractory for wood stove high density silica insulating fire bricks​​  are also used in the partition walls of the carbonization and combustion chambers of coke ovens, the regenerators and slag chambers of open hearth furnaces, soaking furnaces, glass melting furnaces, refractory materials and ceramic firing kilns. There are also vaults and other load-bearing parts for kilns. It is also used for the high-temperature load-bearing part of hot blast stove and the top of acidic open hearth furnace.
