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 content increases.
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, fluorine and alkaline salt erosion, low thermal conductivity and other properties, cement
An ideal material for kiln decomposition zone and transitional zone
