good job and nice quality! Hope our next business

—— Carsten Schmickler

very nice company.waiting for my next visit

—— Neetu Arora

good quality, but price is higher than other supplier.

—— Bipin Vagal

thank you for your products and service. During the project, the staff from your company cooperated with our side perfectly. The goods are all follow our order. The after-sale service also good.

Definition:

 

    Silica Light Weight Refractory Material​​ 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. Insulating silica brick 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. It 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).  Excellent insulation ,security , long working life .

2).  Precise grinding and polishing.

3).  Excellent heat radiation, small size ,more environmental and energy-efficient .

4).  good thermal conductivity
5).  large specific heat capacity
6).  low pressure drop
7).  good heat-shock resisting ability

8).  Working temperature: 600℃-1200℃

 

 

Application:

 

    Silica Light Weight Refractory Material​​ ​​ 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


    Silica Light Weight Refractory Material​​  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.
