High alumina hook brick is a kind of refractory material with major component of AL2O3. High alumina hook brick is made by calcination of alumina or other high alumina content raw materials, with goog characteristics of high thermal stability, refractoriness can be above 1770 ℃. High-alumina hook brick is come from the shape of the refractory material, as the name suggests the shape of High alumina hook brick like hook so called high-alumina hook brick.
Various industries are not the same in the requirements to High alumina hook brick, as well as its classification, according to the shape, (Such as high-alumina hook brick, fan-shaped brick, etc.), alumina (Al2O3) content (such as Grade Ⅰ high-alumina brick, Grade Ⅱ high-alumina brick, etc.), characteristics(Such as micro-expanded High alumina brick, phosphate combined High alumina brick), process methods (such as firing brick, not burning brick, electric cast brick, etc.), raw materials (such as clay High alumina brick, mullite High alumina brick ), uses (such as High alumina brick used for blast furnace, High alumina brick for hot blast stove) and so on.
Application of high alumina hook brick
High alumina hook brick is mainly used for the connection of furnace wall and the wall and wall face wall and arch.
Hongtai produced high alumina hook brick use high alumina bauxite composed of water-containing aluminum oxide minerals (baitite, gibbsite, etc.)

A. refractoriness
High alumina hook brick refractoriness is higher than clay brick and semi-silica brick, up to 1750 ~ 1790 degree, belong to senior refractory.
B. load softening temperature
Because high alumina hook products content more Al2O3, less impurities, less formation of fusible glass , so the load softening temperature is higher than the clay brick, but the mullite crystallization does not form a network organization, so its load softening temperature is still lower than silicone bricks.
C. anti-slag performance
High alumina hook brick contains more Al2O3, close to neutral refractory material, can can resist the acid slag and alkaline slag erosion. Because it contains SiO2, so the ability to resist alkaline slag resistance is weaker than acid slag resistance.
