Decoiling Processing Service Andalusite Brick with High Refractoriness and Top Grade

Product Description

Andalusite refractory bricks

Andalusite refractory bricks have good volume stability and resistance to rapid cooling and heating, strong creep resistance, high load softening temperature, resistance to slag iron penetration and good chemical stability. In addition to reducing fuel consumption and increasing stability, andalusite refractory bricks can also save more than 40% of the consumption of general refractory materials. Andalusite refractory bricks are mainly used for the lining of industrial kilns and thermal equipment with drastic temperature changes such as hot blast stove body, torpedo car, ladle water, glass melting furnace, electric furnace roof and heating furnace.

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.

Differents

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:
$Decoiling Processing Service Andalusite Brick with High Refractoriness and Top Grade 3$
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.
