6. Being lining for high temperature furnace, slurry pump, coal ash slurry pump, and mine slurry pump etc.
7. Being all kinds of unshaped refractory materials and fireclay of high temperature industrial furnace
- Q: What refractory material does cupola lining use?
- It's made of high quality refractory material: 1770 ~ 2000 centigrade.
- Q: What are the requirements for Rubble backfill height?
- 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
- Q: Application characteristics of high alumina brick
- Slag resistance. Due to the high alumina brick products in the three oxidation of two aluminum is neutral and high content, so this material products for acid-base slag corrosion resistance.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- Refractory brick is non-metallic materials can be classified according to a kind of inorganic material, high aluminum brick, clay brick, magnesia brick, corundum brick, mullite bricks, silicon carbide materials such as brick, high alumina brick is used as a relatively wide range of products in accordance with the refractory brick high alumina refractory materials by high aluminum brick is generally divided into Al2O3 content three: I - II - >75% Al2O3 content; the content of Al2O3 is 60 ~ 75%; III - Al2O3 content from 48 to 60%.
- Q: How are the high alumina bricks fired?
- Light and high alumina bricks are usually fired in a weak oxidizing atmosphere. In light and high alumina bricks firing, they are often rich in impurities such as R2O, RO, Fe2O3 and so on. They react with Al2O3 and SiO2 at high temperature to produce liquid phase. In the Al2O3 - SiO2 - R2O system, the growth rate of liquid phase increases with the increase of temperature at high temperature. So, because the increase of sintering temperature brings a lot of liquid phase, the decrease of liquid viscosity will lead to the deformation of brick and the decline of brick high temperature function. Therefore, the lower sintering temperature and longer holding time should be adopted in the sintering process dominated by liquid phase sintering. The production practice shows that the same firing temperature can be used for the high grade aluminum bricks. When fired in an inverted flame kiln, it is usually 1430 degrees centigrade and insulated by 40H. The high alumina bricks such as Ill are 1390~1420 degrees centigrade. When the tunnel kiln is fired, they are 1550 and 1450~1500 degrees centigrade respectively. High alumina brick is usually made of weak oxidizing atmosphere.
- Q: What's the price of high alumina refractory bricks?
- Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.
- 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'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: What causes breakage of refractory bricks?
- There are many factors that lead to the damage of refractory brick, can be divided into: the chemical loss (e.g. salt penetration, redox phenomenon), heat loss (burning, thermal shock), mechanical loss (kiln deformation, thrust, brick masonry quality etc.).
- Q: What are the categories of 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.
