Q:What are the characteristics of high alumina bricks?
A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined.
Q:What are the high aluminum bricks made of?
It's OK to use corundum bricks and alumina hollow ball bricks to build a furnace,
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 can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
Top burning type hot blast stoveIt means that the burner is installed on the top of the hot blast furnace of the iron making equipment, and it does not need a special combustion chamber in the vault space. It is also called a non combustion chamber type hot blast stove.
Q:What is the difference between corundum and high alumina??
The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.
Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.
Q:Is there a big difference between two high alumina brick and one high alumina brick?
The difference between the two kinds of high alumina bricks is great. I perennial in Zhengzhou was responsible for the production and sale of colt refractories
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:Which thermal shock stability of clay brick and high alumina brick is good?
High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
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.
