Product Picture
Produce Processing
- Q:How to improve the thermal conductivity of the coke silicabrick rate?
- To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.
- Q:Brick
- An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance. 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 quartz in the body. 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: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 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:The difference between clay refractory bricks and refractory brick in the application.
- Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use,
- Q:Common bond brick?
- Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.
- 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 formula in the refractory brick, and firing curve, who knows?
- Add 1.8-2.2% of the total weight of the main raw material, and then add lime milk, rolling for 10-15 minutes, and finally add pulp, rolling for 10-15 minutes, out of the mill, forming billet.
- Q:What is the silica refractory products?
- High silicon content in high temperature expansion sintering temperature between 1390-1410 in furnace arch
- Q:Can not use it two brick
- The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.
