Lower price andalusite brick anode baking furnace
Profiles made from andalusite calcined can be used in key parts
such as hot blast stove, hot air tower, reheat frying, etc., can
also be used in a variety of auxiliary pouring and operating
equipment, and can also be used in the production of kiln
facilities, high-temperature aluminosilicate insulators, and
foundry mold fabrics.
Andalusite firebrick made from andalusite can save 30 ~ 50% energy
compared with refractory or light brick lining.The use of
andalusite firebrick can not only reduce the fuel consumption and
increase the stability, but also save more than 40% of the
consumption of common refractory materials.
As a high temperature structural material, hot blast stove brick requires very strict creep rate at high temperature.Andalusite and sillimanite have excellent high temperature structural strength properties.Table 1 lists the performance comparison between andalusite and mullite, bauxite, corundum and other refractory products.It can be seen from Table 1 that the high temperature creep rate of andalusite brick is better than that of bauxite, corundum and most mullite bricks. Andalusite is one of the ideal materials for low creep refractories.
Sillanite, andalusite and kyanite have the same heating phase
transformation behavior, and they all decompose to form mullite and
SiO2 phases, the latter can form either quartzite or glass
phase.The difference is that the volume expansion of sillimanite
and andalusite into mullite is small.While kyanite is very large,
its reaction is carried out as follows:
Since sillimanite and andalusite have only a small volume effect in
the hot mullite process, they can be directly used to make
bricks.It can be burnt or not.The content of Al2O3 of sillimanite
brick is generally 50% ~ 60%. Its remarkable advantages are higher
volume stability at high temperature, softening point under load
and thermal shock resistance than that of high alumina brick.In
modern large melting furnace, in order to ensure the stability of
the melting furnace structure must use sillimanite brick.
Sillimanite bricks are usually fired below the temperature at which
sillimanite decomposes.In the use process, if the use temperature
is slightly lower than the sillimanite decomposition temperature,
the brick volume stability is very good, there is no obvious volume
effect;If the temperature is higher than the decomposition
temperature, sillimanite will decompose into mullite and liquid
phase, and a little volume expansion can offset the contraction
phenomenon caused by the production of liquid phase, and maintain a
relatively stable volume.
Mullite products can be obtained by high temperature firing, that
is, firing at a temperature higher than the decomposition
temperature of sillimanite and andalusite, and the volume expansion
of brick during firing can be controlled well, and the products
with superior performance can be obtained.The results show that the
microstructure of brick made by sillimanite and andalusite without
prefiring is better.This can be explained as: the pre-fired clinker
forms a mullite crystal network, which will be destroyed when
crushed, and it is impossible to form a mullite binding network
during further sintering, which will reduce the compactness and
high temperature performance of the product.
