High Alumina Refractory Brick
High alumina refractory brick, that is, alumina content in 48% or more of an aluminum silicate refractory. Made of bauxite or other raw materials of higher alumina content after molding and calcining. High thermal stability, refractoriness above 1770℃. Good slag resistance.
It can be classified according to its mineral composition, generally divided into five categories: low Mullite (silystone), Mullite, Mullite-corundum corundum - mullite and corundum .
Usually divided into three categories:
Ⅰ: Al2O3 content of 75% or more;
Ⅱ: Al2O3 content is 60% ~ 75%;
Ⅲ: Al2O3 content is 48% ~ 60%;
One of the important properties of high alumina firebrick is its structural strength at high temperature. The high temperature creep is also measured to reflect the high temperature structural strength. The results show that the softening temperature of load increases with the increase of Al2O3 content.
For high alumina refractory bricks with Al2O3 content below 70%, the softening temperature under load depends on the amount ratio between the crystalline and liquid phases, which increases with the increase of the amount of mullite. The quantity and properties of liquid phase have obvious influence on the softening temperature under load. Therefore, reducing the content of impurities in the raw material is conducive to improving the softening temperature of load and high-temperature creep.
Application of High Alumina Bricks
It is mainly used for lining of blast furnace, hot blast furnace, electric furnace top, blast furnace, reverberatory furnace and rotary kiln. In addition, high alumina firebrick is widely used as open hearth grate brick of regenerative type, plug head of pouring system, nozzle brick and so on.
