- Q: What are the main components of high alumina bricks?
- High alumina brick materials according to the main mineral phase can be divided into: aluminum silicate minerals, such as sillimanite, kyanite, andalusite, and synthetic mullite.
- 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: How many cubic bricks does a high alumina brick have?
- It is related to the content of aluminum in high alumina bricks.
- Q: What is the price of the first grade high alumina brick?
- The specifications and different prices, relatively large fluctuations of the main push of the refractory Dongxin high alumina brick high alumina brick prices generally around 3000 have various levels of Dongxin refractories
- Q: What are the common thermal insulation materials for thermal conductivity?
- Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.
- Q: How to make refractory bricks and boiler wall adhesion more firm?
- Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry
- Q: Can high alumina brick resist carburizing?
- Louzhu can use heavy impervious material, it is neither high alumina brick nor mullite, this product can resist seepage and have good compressive strength
- Q: Are there any differences between insulating bricks and refractory bricks?
- Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.
- 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: 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.
