Q: What are the high aluminum bricks made of?: The amount of refractory mud accounts for about 6% of the brick weight

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: Application characteristics of high alumina brick: Load softening temperature. The softening temperature of high alumina brick products decreases with the increase of silica and alkali metal oxide content, but is higher than that of clay brick products, which is about 1420 - 1530 degrees centigrade. Al2O3. The softening temperature of corundum brick with content greater than 95% can reach above 1600 DEG C.

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: 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: Difference between low creep high alumina brick and ordinary high alumina brick: The question is good, these two belong to the high aluminum brick products, when many manufacturers buy, I do not know how to distinguish.

Q: How much is one ton / ton of high alumina refractory brick?: The market price of about super high aluminium brick price at 3000 yuan / ton, a high aluminum brick at around 2500 yuan / ton, two high aluminum bricks at around 2100 yuan / ton three grade high alumina bricks at around 1850 yuan / ton for reference, choose to buy the area is not the same as the prices are not the same.

Q: What are ordinary bricks, refractory bricks, hollow bricks?: Hollow brick is divided into cement hollow brick, clay hollow brick, shale hollow brick. In March 2011 Yunnan Yingjiang earthquake occurred in 5.8, the use of cement hollow brick houses collapsed and killed several people, due to safety concerns that Yunnan intends to disable the cement brick, Shandong Qingdao in the construction of real estate has also been halted the use of cement hollow brick. Professional claims in the construction industry argue that the prohibition of the use of such statements is unscientific and unprofessional. Misleading the public, it must be corrected. Hollow brick is only a kind of building material, and it is no problem to use it in scientific way. Hollow brick in use is very scientific, high quality requirements, the investigation of the foundation is suitable for the use of hollow bricks, how to design, construction, cement and other related ingredients, there are no problems. According to strict procedures, scientific use, strict implementation of relevant national standards, the use of qualified hollow bricks, there is no problem. Similarly, if the use of solid bricks does not strictly comply with the relevant standards of the state, the same will be a problem.

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: The difference between clay bricks and clay bricks: Clay brick is a small building with artificial bulk. Also called sintered brick. Solid clay brick is one of the oldest building materials in the world. It is a building material that is loved by the people.
