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.

- 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.
- 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:What are the specifications for bricks?
- Thecompressive node as a new type of building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, improve work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, it has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process
- Q:What are the characteristics of high alumina bricks?
- A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined.
- 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:How much is one ton / ton of high alumina refractory brick?
- The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012
- Q:What kind of material is the general metal case?
- Ordinary computer chassis and the material itself does not produce high-energy radiation, only in the space environment of the computer is the external defense requirements, and in the space structure, the use of lead as protective materials, unbearable weight.
- Q:Is glass wool inorganic thermal insulation material?
- The characteristics of glass wool, glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.
- Q:Introduction of high alumina brick
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not identical. For example, European countries limit the content of Al2O3 to high alumina refractories by 42%. In China, the content of Al2O3 in high alumina brick is usually divided into three parts: I, etc. - Al2O3 content, >75%, II, etc. - Al2O3 content is 60 ~ 75%, and the content of Al2O3 is 48 ~ 60%.
- Q:Density of high alumina bricks
- Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. The volume density is 0.4 ~ 1.35g/cm3. The porosity is 66% ~ 73%, and the compressive strength is 1 ~ 8MPa. Better thermal shock resistance.
