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: Application characteristics of high alumina brick: Reheating line change. If the firing temperature of high alumina brick products is enough and the firing time is enough, the volume is stable, the change of the reheating line is small; on the contrary, the residual shrinkage of clay brick products is caused by recrystallization.

Q: How many cubic bricks does a high alumina brick have?: Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.

Q: What's the price of high alumina refractory bricks?: The price of high alumina refractory bricks varies greatly according to the content of AL2O3.

Q: What is the density of a super high alumina brick and what is the price?: Of course, the transaction price, please choose refractory brick manufacturer is better.

Q: What are the specifications for bricks?: In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.

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: How to test the aluminium bricks of high alumina refractory bricks?: Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard

Q: How to reduce the harm caused by two times mullite in high alumina refractory material: Prolong the sintering time and adjust the aluminum content of the high alumina brick.

Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.

Q: High alumina brick 80 with which high aluminum cement?: In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.
