Anti-Strip Aluminum Brick Introduction:

The Anti-stripping Aluminum Brick is produced with special bauxite chamotte by adding aragonite or Zro2 and molding under high pressure according to a certain proportion . Featured by strong anti-strip capacity, kalium, sodium, sulphure, chlorine and basic salt resistance and low thermal conductivity, it is an ideal material for the transition zone and decomposing zone of cement kiln.

Anti-Strip Aluminum Brick Specifications

1. Anti-strip alumina brick certified by ISO.
2. Strong anti-strip stability
3.low thermal conductivity

Anti-Strip Aluminum Brick Application:

Widely used in constructing the latter decomposition zone and transitional zone of the rotary cement kiln.

High Quality Low Price Anti-strip Aluminum Brick

Q: In 2016, a few of the traditional refractory materials will be able to survive: The other is in large enterprises and individual has the unique advantage of the small enterprises, with independent technology system, production equipment advanced, there are certain funds set up to deal with risk, timely reform, such enterprises compared to a few years ago the productivity and sales or have declined, but overall is still in the stage of production increased steadily.

Q: What is the price of the latest thermal insulation material?: There are many kinds of insulation materials, and the price will fluctuate with the market. Small quantities of inquiry or procurement, then go directly to the local thermal insulation market, a wide variety of prices are basically the market price.

Q: What's the difference between high alumina refractory bricks and high alumina refractory bricks?: The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.

Q: Aluminum content 38, silicon content 55 What refractory bricks?: High alumina brick:The mineral composition of the high alumina brick is determined by the bauxite used. The mineral composition of the clinker is usually mullite, corundum and glass. The theoretical composition of mullite is Al2O371.8%, SiO2 28.2%, and its melting decomposition temperature is 1840 DEG C. With acicular crystal, network cross structure, high temperature state showed better strength. Corundum in the form of alpha -Al2O3, melting point of 2050 degrees, hardness of Mohs 9, showing a granular and columnar crystal, has good chemical stability, acid, alkaline slag have a certain resistance. Based on the composition of mullite minerals, the phase composition of high alumina brick can be judged according to the content of Al2O3. When the bricks are below Al2O3 71.8%, the base of the composition is mullite and SiO2, such as grade LZ-48 bricks. Because it contains a large number of SiO2 formed in the liquid phase under high temperature is 20% ~ 30%; brick in Al2O3 more than 71.8%, the excess Al2O3 formed corundum crystal under high temperature, while generating 2 high temperature phase, eutectic temperature rise by the low content of Al2O3 brick 1595 C to 1840 C, such as grade LZ-75 brick. In fact, it is impossible to produce a complete phase equilibrium in the process of production, but the glass phase is very small, and there is no more than 10% in the partial gap of the Yu Jing phase

Q: What is the content of free silica in the refractory bricks of high alumina bricks?: In the meantime, the free silica content of silicon brick is as high as 90% above. Therefore, the most serious damage is silicon brick, followed by clay brick, high alumina brick, magnesia brick and so on.

Q: What's the weight of the refractory bricks?: Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.

Q: How high can aluminum bricks expand at 80O degrees of heat?: The expansion of high alumina brick is not only related to temperature, but also related to its material composition. The refractory temperature of high alumina brick is above 1770 centigrade. The temperature of 800 DEG C has little influence on the expansion of high alumina brick.

Q: How are the grades of high alumina bricks differentiated?: High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%

Q: How does the physicochemical index change when the high alumina brick is used at high temperature?: If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.

Q: What are the categories of bricks?: Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.
