Firebricks Description
High alumina insulating fire brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory,which has such advantages as high porosity, small volume density,good insulation effect,high mechanical intensity,small thermal conductivity and long service life.For various industrial kilns&furnaces,it is a kind of essential refractory for energy saving and temperature preservation.This series of High Alumina fire resistant brick are made of selected high alumina bauxite, kaolin caly,hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature.
Firebricks Application
High alumina bricks are commonly used in blast furnace,hot blast furnace,the roof of electric furnace,teeming ladle,rotary kiln,regenerator etc.
Firebricks Features
.Low thermal conductivity
.Excellent acid and base slaging resistance
.High refractoriness
.Excellent thermal shock resistance
.Excellent mechanical strength

FAQ
Q1 What’s the transport method?
A1 FCL delivery goods with wooden pallet or wooden case by sea; If LCL delivery, must with wooden case; Sometimes need open top, flat rack or bulk cargo.
Q2 What’s the required payment term?
A2 Generally 30% TT as the prepayment, 70% TT before delivery. If need, 100% Irrevocable Letter of Credit or negotiation.
Q3 Which country are our products exported to?
A3 Apart from entire Chinese market, the US, Russia, Japan, Korea, Australia and some Southeast Asian Nations.
- Q: Is there a big difference between two high alumina brick and one high alumina brick?
- According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.
- Q: In 2016, a few of the traditional refractory materials will be able to survive
- In short, the overall market of refractory enterprises is in a turbulent adjustment process, but the volume is still in place. Elimination is inevitable, as to how many can be eliminated, dare not assert.
- Q: What are the grades of high alumina bricks?
- High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick
- Q: Aluminum content 38, silicon content 55 What refractory bricks?
- Hello Only on behalf of the Zhengzhou colt as refractory product index your answer to this question is not entirely separate from the chemical index of aluminum content, silicon content and judgment, personally think that three types of refractory bricks may respectively is: Two: semisilica brick high alumina brick
- Q: What are the characteristics of high alumina bricks?
- High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining. High R.U.L, low creep high alumina brick with high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials.
- Q: What kinds of minerals are there in the five major categories of ore crystal chemistry?
- Halide. A few species, about 120 species, accounting for only 0.1% of the earth's crust. Most of them formed in the surface conditions, forming a salt mineral, containing less pigment ions, light color, low hardness, generally less than 3.5. Common mineral halite (NaCl), potassium (KCl), fluorite (CaF2) etc..
- Q: What are ordinary bricks, refractory bricks, hollow bricks?
- Hollow brick is divided into cement hollow brick, clay hollow brick, shale hollow brick. In March 2011 Yunnan Yingjiang earthquake occurred in 5.8, the use of cement hollow brick houses collapsed and killed several people, due to safety concerns that Yunnan intends to disable the cement brick, Shandong Qingdao in the construction of real estate has also been halted the use of cement hollow brick. Professional claims in the construction industry argue that the prohibition of the use of such statements is unscientific and unprofessional. Misleading the public, it must be corrected. Hollow brick is only a kind of building material, and it is no problem to use it in scientific way. Hollow brick in use is very scientific, high quality requirements, the investigation of the foundation is suitable for the use of hollow bricks, how to design, construction, cement and other related ingredients, there are no problems. According to strict procedures, scientific use, strict implementation of relevant national standards, the use of qualified hollow bricks, there is no problem. Similarly, if the use of solid bricks does not strictly comply with the relevant standards of the state, the same will be a problem.
- Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
- High alumina brick clay brick up to 1700 degrees above 1500 degrees -1750 degrees of magnesia brick and magnesia chrome brick 1500-1650 degrees, I is the production of clay brick, brick my temperature at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it
- Q: What should be used as binder for making high alumina bricks?
- Bond for making high alumina brick: soft clay has good plasticity, so the high alumina brick is usually made of soft clay as bond. However, the free Al2O3 free SiO2 and bauxite clinker clay in under 1200 degrees occurred two times of Mullization reaction, generate large volume expansion, silicon porosity, strength reduction. Therefore, the amount of clay powder in the ingredient should be no more than 5%.
- Q: High alumina brick 80 with which high aluminum cement?
- Which kind should be chosen should be determined according to the conditions of use, life expectancy and cost control. By the way, the quality of masonry is also very influential.
