Features of High Alumina Refractory Bricks

High Refractoriness

The Al2O3 in aluminum oxide bricks can withstand high temperatures. And Kerui factory has the advantage of raw materials. High purity Al2O3 brings high refractoriness. This high alumina brick can be used up to 1750-1790℃.

High Load Softening Temperature

Among the alumina silica bricks series, Kerui alumina lining bricks have a high load softening temperature and are structurally stable at high temperatures. It avoids expansion, deformation, slagging, etc.

Strong Slag Resistance

Resistant to acidic slag and alkaline slag. In addition to strong acid and alkali kiln environment, the use of high alumina brick is a suitable choice. High alumina bricks as lining can protect the kiln from media penetration.

High Stability

The high alumina bricks chemical composition has a large amount of mullite, which has the advantage of a very good particle structure. Therefore, it can maintain stable property in hard working environments. If you’re interested in more information, plesase visit Pinterest.
