For High alumina brick the temperature of refractoriness under load
is normally above 1420~1550℃ that is higher than the fireclay brick
and it increases along with the AL2O3 content enhances.
For High alumina brick the thermal Shock resistance is mainly
decided by chemical contents and its mineral microstructure but its
thermal shock resistant is worse than the fireclay brick.
High alumina brick have very good ability of anti-acidity,
anti-metal fluid corrode and anti-oxidation.
High alumina brick are used normally in industry furnaces such as
Blast furnace, hot-blast furnace and EAF etc.
As for high alumina brick series products, we excel our other high alumina brick suppliers in many aspects, such as:
We enjoy the biggest production lines of high alumina brick and largest production capacity.
---More than 8000 mts high alumina brick can be supplied per month. We can help you save your time limit for a project. Besides, we provide a small number of high alumina brick used for kinds of furnace maintenance as well.
Advanced technology makes it possible for us to have very high qualified rate of high alumina brick .
---Our qualified rate of high alumina brick has so far reached over 98%, therefore, our high alumina brick enjoy excellent quality and reasonable price from the point of view.
This index applies to SK series high alumina bricks. SK series high alumina bricks include SK-40 high alumina brick; SK-38 high alumina brick; SK-36 high alumina brick; SK-34 high alumina brick; SK-32 high alumina brick.
