Mullite Brick(lightweight refractory brick )
1.Classification tempe: 1300~1600C
2.Density:600~1100kg/m3
3.Size:230x114x64mm

Mullite Brick is made from high-grade and high purity refractory powders and materials. During the process of production, organic and multiple filling materials are injected accoridng to the required proportion. LUYANG mullite brick is compressed in vacuum and sintered under high temperature.

Application

Lining and back lining of various furnaces in the industry of metallurgy,petrochemical,ceramics,machinery and building materials.For instance:
the cracking furnace,conversion furnace, heating equipment,refining equipment,reproduction equipment,hot blast stove,heating furnace, tunnel kiln,shuttle kiln,glass-pool kiln,tec

Standard Specification

$Mullite Brick ( Lightweight refractory Brick with low price,the largest refractories supplier in China)$

Q: The introduction of silica brick: Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.

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: The introduction of silica 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: Such purpose and scope please give me detailed points thank you because I am learning stage: Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.

Q: Glass kiln brick for physical and chemical indicators?: Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.

Q: Semisilica brick, clay brick, high alumina brick and what is the difference?: The share of A12O3 and SiO2 is different

Q: How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?: Mainly from the impurities to determine how much, generally less impurity single color brick.

Q: How to improve the thermal conductivity of the coke silicabrick rate?: The content of SiO2 is 98.23% crystalline silica as raw material, with sulfite pulp liquid as binder, millscale and lime as mineralizer, by Jin Hongshi (TiO2) as additive, can improve the rate of thermal conductivity of silica brick for coke oven. When the rutile content is 1.5%, the coefficient of thermal conductivity of silica brick for coke oven is 2.66W/ (m.k).

Q: Physical solid waste disposal: Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products when firing, reduce cracks, improve the rate of finished products.

Q: Such purpose and scope please give me detailed points thank you: Mainly used for coke oven carbonization chamber and the combustion chamber wall, open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace, refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
