- Q: What are the grades of high alumina bricks?
- High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick
- Q: What is the standard size of high alumina brick?
- The country has laid down a number of criteria for the use of refractory bricks to unify market demand.
- Q: What is the standard classification of high alumina bricks and high alumina bricks?
- High alumina brick is a kind of refractory material in refractory brick products. It is made of refractory clay or other refractory material. It belongs to the product of Si Al System
- Q: The difference between aluminium refractory and magnesia refractory
- Aluminum refractory belongs to neutral refractory material, usually refers to silicon aluminum refractory materials, such as: high alumina brick, clay brick, high alumina castable and other products, the production of raw materials is mainly bauxite.
- Q: What materials are used for roof insulation?
- There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.
- 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: Corundum, high alumina and fireclay refractory difference is what
- Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
- 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
- Q: What is spalling resistant high alumina brick?
- Using bauxite as main raw materials, the introduction of a small amount of ZrO2 (ZrO2 is due to phase transition, between monoclinic and tetragonal type can improve the thermal stability of the products), adding a certain amount of binder and additives, the particle size distribution control mud, forming and sintering of refractory products produced, called anti stripping high alumina brick.
- Q: How to reduce the harm caused by two times mullite in high alumina refractory material
- Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
