- Q: How much is one ton of high alumina refractory brick?
- High alumina refractory brick according to the different content of AL2O3 is divided into grade, grade one and grade two, and grade three high aluminum brick, Zhengzhou Kang Hui refractories factory price in 800-1900 yuan / ton, stable quality, are exported to the domestic and foreign markets.
- 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: Corundum, high alumina and fireclay refractory difference is what
- They differ in that the alumina content is different, and the content is in order: corundum > high alumina > clay.
- Q: The difference between ordinary and diatomite brick refractory brick
- Insulation products made from diatomaceous brick and porous diatomite. The main raw material is natural porous diatomite, and then a small amount of clay and fuel are added. The volume density of diatomite brick was 0.7g/cm3, compressive strength at room temperature is 1 ~ 2MPa, the coefficient of thermal conductivity at 400 C for 0.13 ~ 0.20W/ (M - K), the apparent porosity is greater than 70%, the coefficient of thermal expansion (1280 degrees) 0.9 x 10 - 6 DEG -1, refractoriness is greater than 1250 DEG C. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius.
- Q: How to distinguish the good or bad of the high aluminum brick?
- In the procurement of high alumina brick, the first color, high quality aluminum brick, brick surface smooth, yellow color pale, four sides equal, no broken angle, no cracks.
- Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?
- The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
- 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: What are the lining structures of lime rotary kilns and what are the requirements for refractories?
- The rotary kiln lining structure of rotary kiln and requirements on refractories calcining active lime according to the general output is divided into Nissan 300t, 400 t, 600 t, 800 t, 1000 t, 12000 t of kiln type, calcining zone temperature at 1350 degrees celsius. The kiln is divided into a discharge end, a cooling zone, a burning zone, a preheating zone and a feeding end, and the temperature of each section of the kiln ranges from 1000 DEG C to 1350 DEG C, and the requirements for refractory materials are different. The kiln refractory materials not only to withstand the high temperature impact, but also need to bear the material erosion, kiln rotation stress produced, so not only on the physico-chemical properties of refractory materials have strict requirements, but also for the construction of brick should be strictly.
- Q: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
- Because the hot air outlet of the top burning hot blast furnace is high, the installation requirement of the hot air manifold is high, and the requirement of the strength of the pillar structure is higher, so the rectangular arrangement of the hot blast stove is arranged. The top burning hot blast stove is located on the furnace top because of burner and hot air valve,Therefore, operation, maintenance and installation all require mechanization and automation. Also, because these water cooled valves are mounted with a high elevation,Therefore, the demand for cooling water supply pressure should be improved accordingly, the use of large top burning hot blast stove, the key lies in the design of high-power high-efficiency short flame burner. The top combustion hot blast furnace absorbs the advantages of internal combustion and external combustion hot blast stoves, and overcomes some of their shortcomings,Its structure can meet the requirements of modern blast furnace for high temperature, high pressure and large scale development,Combustion capacity, while meeting production requirements, has been successfully reduced by many devices,
- 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.
