Aluminium silicate refractories
Refractory materials, also known as refractories, are materials that are used in extremely high temperature applications. They usually have proper thermal, mechanical and chemical properties to resist the attack of high-temperature gases, molten metals and slags. Aluminium silicate refractories are used in many industries, such as metallurgical, chemical, petrochemical and other industries. It is a kind of heat-resistant material that has the characteristics of high temperature resistance, non-toxic and non polluting, easy construction and so on.
As an important component of refractory materials, purifying and advanced alumina silicate products play an important role in the high temperature environment of metallurgical furnaces. Developed in response to increasing demand, these products include sintered or unburned alumina. The low-temperature sintered alumina promotes good thermal shock resistance, high-temperature strength and slag erosion resistance. Unburned alumina has excellent properties of high temperature resistance, deformation resistance and skid resistance. They are well used for the protection of the furnace. Boats, ladles, sliding channels and other metal container linings require high-temperature stability and good corrosion resistance.
Aluminium silicate refractories are composed of alumina, silica, magnesia, soda and other concentrations. When they are exposed to high temperatures, they form a dense, self-repairing crystal structure, allowing them to resist oxidation and corrosion. The strength of the refractory material is related to the composition of the glue. In order to improve the strength and the ability of standing dynamic shock veins, the special structure clay should be adding in the glue of alumino silicate refractory materials to regulate the refractoriness and thermal conductivity.
Alumina silicate refractories also have other application in ergonomic operation and cost-effectiveness. Their relative light weight makes them easier to handle than heavy materials such as fired bricks. In addition, precision items, such as slabs and precast shapes, can be cast to match the design of a furnace or build the required architectural form. They are generally easier to install and maintain than other refractory products.
In conclusion, alumina silicate refractories are materials used in high temperature industrial applications, such as steelmaking, construction, petrochemical and other processes. They are strong and durable, with good thermal shock resistance and excellent corrosion resistance. In addition, they are relatively light weight and easier to install, making them an economical choice for many applications.
