FUSED CAST BRICK
CMAX Bricks made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.
Application
Advantage
Fused cast AZS (alumina, zirconia and silica) firebricks are mainly categorized into 33#, 36# and 41# according to different zirconia's contents from 33% to 41%.
Fused cast alumina (α-β Al2O3 and β Al2O3) firebricks are composed of alpha alumina, beta alumina and small amount of glass phase.
Both AZS and alumina firebricks have shown excellent performance in glass furnace construction.

- Q: Why is the house made of refractory bricks not warm in winter
- Refractory bricks are not used in the house, but used in a large boiler inner
- Q: What's the difference between a high aluminum brick and a clay brick, two?
- There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color. For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
- Q: does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
- generally is refractory insulation materials, casting materials.
- Q: What are the disadvantages of sintered clay bricks?
- Advantages: brick is the traditional wall materials, has high intensity and durability, but also because of its porous and has the advantages of heat insulation, sound insulation and absorption, therefore suitable for building envelope, interior walls, exterior walls, columns, arches, chimney, channel and other structures have been widely used in masonry the building, is also available in mid proper or steel wire reinforced masonry concrete structure to replace the post and lintel.
- Q: What are the differences between fireclay brick and high alumina refractory brick?
- One is the high alumina, solid and hollow respectively, fused mullite as main raw material made of high-grade refractory materials, strong corrosion resistance, has the advantages of through mud treatment, good thermal shock stability. Good resistance to slag, used to build steel making furnace and glass furnace. High alumina brick is a kind of refractory material. Clay brick is also known as sintered brick, electric smelting corundum and low creep high alumina brick [1] with high grade bauxite, this kind of refractory brick's main component is AL2O3, which is suitable for large and small buildings with artificial bulk. High thermal stability. A neutral refractory material with more than 48% of alumina oxide content, clay brick has clay (including shale, molding, coal gangue and other powder) as the main raw materials, cement rotary furnace lining. The product has a small high-temperature creep, one is clay. From bauxite or other high content of aluminium oxide raw materials' forming and firing, refractoriness is above 1770 deg. High R.U.L and medium-sized hot-blast furnace is different firstly in the material, forming from drying and roasting
- Q: the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
- The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
- Q: What matters should be noticed when using clay refractory bricks in a glass kiln?
- There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
- Q: Can you direct the clay brick walls embryo
- Must not。 Not damp, damp, air tight, poor pressure bearing, bad adhesion between bricks and bricks
- Q: What is the proportion of lightweight fireclay bricks?
- It is a lightweight refractory product containing aluminium 30%-46%. It is made of clay clinker or light clinker as the main raw material. It is usually produced by combustible material. It can also form porous structure by chemical or foam method.
- Q: What are the main constituents in non clay brick sintering?
- Sintered clay brick, it is through the mining soil, brick making, modulation, drying, roasting and cooling produced, roasting coal amount is solid sintered clay brick coal blending amount of 20-60%, the amount of coal to ensure product's surface.
