Classification of High Alumina Brick
High alumina brick is a kind of refractory material, mainly divided into high alumina brick, low creep high alumina brick, high load soft high alumina brick, small expansion high alumina brick and so on. follow me and understand this question.
Common High Aluminum Brick
The primary mineral composition for the high alumina brick to rock, corundum and glass phase, with the increase of the content of Al2O3 in finished products mullite and corundum also increased, glass phase will be reduced correspondingly, finished product and high temperature function refractoriness travel accordingly. It is widely used in various thermal kilns. Compared with clay bricks, the lifetime of kiln furnace can be effectively advanced.
High Load Soft High Aluminum Brick
Some matrix in addition to the three stone concentrate, according to the chemical composition to the mullite after burning theory, introduced the reasonable high aluminium material, such as corundum powder, high-alumina corundum powder;Contact agents select excellent ball clay, depending on different types of clay composite contact agents, perhaps mullite contact agents.
Dilatant High Alumina Brick
This brick is made of high alumina bauxite as the primary stock and added three stone concentrate according to the production process of high alumina brick. The selected tri-stone deposits are preferable to composite data. Because the temperature of differentiation of the three stone deposits is different, there are differences in the expansion of mullite.
Low Creep High Alumina Brick
Low creep high alumian brick is based on the use of the kiln temperature condition, add the three stone mineral deposits in the matrix, activated alumina, etc., make the matrix structure is close to or completely mullite, because the matrix of mullite petrochemical, will travel information of mullite content and falling glass phase containing, and mullite excellent mechanics, thermology, function is advantageous to the data of high temperature function.
