55%min Al2O3 Content High Alumina Refractory Brick for Steel and Iron Industries

China refractory manufacturer factory supply high alumina refractory brick price tons for steel and iron industries

High alumina refractory brick price tons for steel and iron industries, 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.

High alumina lining bricks can be classified according to its mineral composition, generally divided into five categories: low Mullite (silystone), Mullite, Mullite-corundum  corundum - mullite and corundum.

The high alumina lining bricks 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 lining brick 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 blining ricks 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.

The weight of heavy high aluminum brick, also called high aluminum brick, is many times heavier than that of light high aluminum brick. In the process of use, it is not for heat insulation and heat preservation, but more importantly for fire-resistant temperature. It is usually in direct contact with the flame in the kiln during use, so heavy high aluminum brick usually has the function of high temperature resistance. Select high bauxite clinker combined with refractory clay, according to the multi-stage batching, press molding, high temperature burning. The high alumina brick is divided into three grades according to the alumina content. The alumina content and high temperature resistance of the high alumina brick are guaranteed by adjusting the ratio of high alumina clay to the combined clay.
