- 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: 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 one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.
- Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- Quality requirements for aluminium bricks of different grade. 2, high aluminum powder and high alumina aggregate and other materials of reasonable proportion, to reach the production requirements.
- Q: How many cubic bricks does a high alumina brick have?
- It is related to the content of aluminum in high alumina bricks.
- Q: The difference between aluminium refractory and magnesia refractory
- Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.
- 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: Which is faster for heat transfer between corundum bricks and high alumina bricks?
- There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
- Q: Can high alumina brick resist carburizing?
- It is heavy brick mullite brick, brick to do the heavy weight to more than 2.4 manufacturers can achieve a few feeling
- 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
