General Information of Silica Brick For Coke Oven-G95

Our corporation produces a comprehensive range of silica bricks, with high silica content, all of these bricks exhibit excellent performance.

Our Silica bricks are the final result of blending excellent tridymite and cristobalite, as the main raw materials with cutting-edge technology, after mixing, drying, forming, in the high temperature shuttle kiln. There are also little quartz and vitreous within. We ensure you that the silica bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Our competitive Advantage:

1.Competitive Price. Make the products competitive in your market.

2.Abundant Experience. Prevent cracks and twist in bricks.

3.Different Moulds. Save mould fees for you.

4.Lower ferric Oxide,porosity,higher refractoriness,density,higher CCS and exact tolerance.

5.Strict Quality Control. Meet clients’ quality requirement.

6.Safty packing,prompt delivery time,and excellent after-sales services.

7.Large stocks. Guarantee prompt delivery.

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: Physical solid waste disposal: Reduce crack production and improve yield. The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem

Q: Why is the new trend of the high thermal conductivity of silica brick: The high thermal conductivity of silica brick all inherits the advantages of traditional coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity.

Q: Why is the three oxidation of two silicon is very harmful impurities in silica brick: Can generate the material needs is the best way to see the impurity problem!! the first consideration is whether can get the material impurities with what method choice after the time! Miscellaneous reactions cannot have new impurity formation! Selected cannot and need material reaction reagent!

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.

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: The chemical composition of silica brick and its physicochemical index?: ????Al2O3 SiO2??????fe2o3??????cao???????r2o93～98?0.5～2.5?；；?0.3～2.5??0.2～2.7；??1～1.5；

Q: What is the silica refractory products?: Refractory brick with silica content greater than 90%.

Q: Why in the production of the brick to detect the volume density: Fast density test, please consult an instrument.

Q: High temperature refractory material?: Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.Now the definition of refractory materials, has not only depends on whether the refractoriness at 1580 DEG. Refers to the current refractories used in metallurgy, petrochemical, cement, ceramics and other production equipment with inorganic non-metallic materials.
