Refractory high temperature technology is to serve the basic
materials, industrial kilns and has a very close relationship.
Industrial furnace due to different uses and conditions of use, the
basic material of its body - refractory requirement is different.
But also due to the different types of refractory mineral chemical
composition, and differences in the production process of different
microstructure, showing the different basic characteristics.
Firebrick temperature not lower than 1580 ºC inorganic non-metallic
materials, stability, resistance to high temperature firebrick in
the absence of load, ie no load conditions at high temperatures
without melting performance called refractoriness. It represents
the basic properties of refractories. Because of the refractory
material is mainly used as a structural high-temperature furnace
and other equipment as well as high temperature thermal containers
and components for industrial use, it can withstand a variety of
physical and mechanical changes in the role therein. Need to meet
the following requirements:
In order to meet the requirements of high temperature operation, it
has to be at a sufficiently high temperature without softening
performance does not melt.
Alumina brick line with high-quality bauxite, high pressure molding
high temperature firing of bricks, hierarchically divided into a
high alumina bricks, high alumina two, three alumina brick, mineral
composition according to classification, general It can be divided
into: low mullite (silicon line stone), mullite, mullite -
corundum, corundum - mullite and corundum five.
One of the important nature of the work is high alumina refractory
products structural strength at high temperature, this feature is
typically used to assess the load softening deformation
temperature. In recent years, high-temperature creep resistance was
also measured to reflect its high-temperature strength of the
organization. Load softening temperature with increasing alumina
I produced the anti-stripping alumina brick high-grade bauxite is
the main raw material, adding three stone or ZrO 2, by a certain
ratio by high pressure into
Type prepared baking products. Products with strong anti-stripping
ability, but also has to engage in potassium, sodium, sulfur,
