1550C High Alumina Refractory Bricks For Industial Furnace
Definition:
High-Alumina Bricks are mainly made from chamotte, being high pressure pressed and
sintered in high temperature. Main minerals compositions are
mullite phases. These products are widely used in all parts of
furnace lining for middle and small capacity blast furnaces because
of their excellent physical and chemical properties in high
temperature. It also can be used in lining for other kinds of
furnace.
One of the important working properties of High-alumina refractory
bricks is the structural strength at high temperatures. The
high-temperature creep properties are also measured to reflect the
high-temperature structural strength. From the test, we knew that,
with the increase of the Al2O3 content, the structural strength
also become higher.
Advantage:
Competitive Price. Make the products competitive in your market.
Abundant Experience. Prevent cracks and twist in bricks.
Different Moulds. Save mould fees for you.
Strict Quality Control.
Meet clients’ quality requirement.
Large stocks. prompt delivery.
Application:
High-Alumina Bricks that mainly used for lining blast furnaces, hot blast stoves, electric
furnace tops, blast furnaces, reverberatory furnaces, rotary kilns.
In addition, high-alumina bricks are also widely used as
open-hearth regenerative lattice bricks, plugs for pouring systems,
nozzle bricks, etc.
However, the price of high alumina bricks is higher than that of
clay bricks, so it is not necessary to use high alumina bricks
where clay bricks can meet the requirements.
