General Information:
CMAX brand Silica bricks are made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.
Features of Refractory silica bricks for Glass Kiln:
1. high volume density of 2.34 g/cm3
2. high SiO2 content of 96%
3. low iron content of 0.8%
4. low melting point of 5%
Applications of Refractory silica bricks for Glass Kiln:
Because of the high temperature resistant performance significantly, long service life characteristics (as long as more than eight years) of refractory silica brick for Glass Kiln, it can significantly improve the quality of glass, so the refractory silica bricks are widely used in all kinds of glass furnace melting department, regenerator and other important parts.

- Q: What is the main constituent of refractory brick?
- Primarily magnesium oxide and sodium silicate as binder.
- Q: How about the prospect of refractory material?
- Due to the rise of raw material, the prospect is not good with inflation, lower prices and decreased profits. The product requirements have been enhanced and there is vicious competition. Therefore, it is really bad.
- Q: How is the grading of the level A new material fire insulation material?
- The standard to distinguish level A and level B is the different fireproofing coefficient. The level A is non-combustible. The level B is divided into B1, B2 and B3. B1 is flame retardant, B2 combustible and B3 flammable. The level A is commonly phenolic aldehyde, rock wool, thermal?mortar, foam ceramics, foam glass and foam concrete on the current market. Among the advantages of level A materials, the biggest one is foam concrete currently, also known as foam cement, which the Xuzhou Green Year EEB company's main produces.
- Q: What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
- Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".
- Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.
- who knows the classification of fireproofing glasses, how long is the fire-resistant time?
- Q: Which kind of external wall fire barrier zone material is better?
- The following types are: rock wool, aerated concrete, phenolic aldehyde and foam cement rock wool fire barrier zone "rock wool board" mainly uses water-repelling rock wool board produced by pendulum method as thermal insulation layer materia, and connecting and fixing base wall by binding and nail bonding, it is composed level A non-combustible building energy efficiency thermal insulation system by plastering layer composed by plastering mortar and glass?fiber mesh and decorative mortar finishing layer or coating. Good air permeability
- Q: What kind of refractories do the anode baking furnace use?
- 5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
- Q: What are refractory materials?
- Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
- Q: How many fire endurance grades are the AAA fire resisting shutter divided?
- The fire shutter is divided into A / B / C classes. The refractory limits are not less than 1.2 /0.9 /0.6 hours. References to "general technical specification for steel fire resistance rolling shutter door GB 14102-93". 4.3 4.3.1 Classification according to fire resistance time. The common steel fire resisting shutter(see Table 3) The categories of the codes of the refractory time hF1 1.5F2 2.04.3.2 composite steel fire shutter composite steel fire shutter(see Table 4). Table 4 and Category Code refractory time hF3 2.5F4 3.04.4 refractory press time, smoke performance classification 4.4.1 ordinary steel fire anti-cigarette curtain (see Table 5) Table 5 and category code leak smoke refractory time h (20Pa pressure) FY1 1.5 ≤0.2m3 / m minFY2 2.0 ≤0.2m3 / m min4.4.2 composite steel fire anti-cigarette curtain (see table 6) table 6 and category code leak smoke refractory time h (20Pa pressure) FY3 2.5 ≤0.2m3 / m minFY4 3.0 ≤0.2m3 / m min excerpt complete fire shutter when the fire district for fire resistance of 3 hours, the opening portion on the firewall setting fire shutter fire resistance of 1.2 hours. **** Fire resistance of 3.0 hours called premium (fire back surface). "Construction Regulation" is mentioned in setting up a firewall and used as the separation of the fire resisting shutter and the fire?compartments. When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the fire endurance should not be less than 3.00h; When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the two sides of the roll should have protection of ?closed automatic water spray system, and the duration of water spray system should not less than 3.00h. In summary: The fire resisting shutter can be divided into: Grade, A, B and C looking to adopt
- Q: How many grades of fire?rating are there for interior decoration materials?
- It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.
