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

- 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.
- Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?
- High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick
- 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 are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- The brick Pei boring and time. 6, Pei brick kiln installed between the brick and the brick Pei order, Pei and kiln top, kiln wall gap etc.. 7, high alumina brick kiln plan, and the lack of edges and corners of the scene should be avoided.
- Q:Is there a big difference between two high alumina brick and one high alumina brick?
- The difference between the two kinds of high alumina bricks is great. I perennial in Zhengzhou was responsible for the production and sale of colt refractories
- Q:What are the requirements for Rubble backfill height?
- Backfill should be filled with large stones, big face, small face upward, the decoration is stable, and then use small stones leveling, the gap between the stones can be swept into the slag, gravel, so that the gap filled.
- Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
- High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.
- Q:Which thermal shock stability of clay brick and high alumina brick is good?
- Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products
- 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:What are the high temperature refractory mortars made of?
- Products used in metallurgy, building materials, machinery, chemical, power industry, industrial thermal furnace, for masonryBuilding clay brick, high alumina brick and corundum brick have the characteristics of full grey seam, good airtightness, high bonding strength, high temperature performance and suitable construction time
