In high-temperature applications, the heat resistance of materials is of paramount importance. Corundum refractory bricks, being a high quality refractory material with corundum as the main component, have become, due to their outstanding properties, the most important material for high temperature applications. ideal choice for lining high-temperature furnaces and furnaces. In this article we will take a closer look at characteristics, utilization и selection tips corundum refractory bricks to help you better understand these defenders of high-temperature industries.
I. Exceptional properties of corundum refractory bricks
- Ultra-high fire resistance: Due to their melting point of up to 2050°C, corundum refractory bricks are able to withstand extreme temperaturesIt maintains structural stability and resistance to softening or deformation at high temperatures.
- Excellent heat resistance: These bricks have a superior heat resistanceThey can withstand sudden temperature changes without cracking, making them suitable for use in environments with frequent temperature changes.
- High resistance to erosion: The chemical stability of corundum provides an excellent erosion resistance from acidic, alkaline slags and molten metals, which significantly extends the service life of the furnaces.
- High mechanical strength: Due to their dense structure, corundum refractory bricks have high cold compressive strength и hot bending strengthThis allows them to withstand mechanical stresses and high-temperature influences.
II. Wide range of applications for corundum refractory bricks
Thanks to its excellent properties corundum refractory bricks are widely used in the following areas:
- Ferrous and non-ferrous metallurgy: Lining of blast furnaces, air heaters, converters and electric arc furnaces.
- Production of building materials: Lining of rotary kilns for cement and glass melting furnaces.
- Petrochemical industry: Lining of high temperature reactors such as cracking furnaces, gasifiers and reformers.
III. Tips for choosing quality corundum refractory bricks
- Identify utilization requirements: Choose the right type and specification of corundum refractory bricks depending on the type of furnace, operating temperature and corrosive environment.
- Pay attention to the performance of the product: Pay particular attention to key indicators such as refractoriness, bulk density, apparent porosity и cold compressive strength.
- Choose reliable manufacturers: Favor manufacturers with production certificates, technical expertise и good reputationTo guarantee the quality of products and after-sales service.
IV. Conclusion
As an indispensable material in high-temperature industries, corundum refractory bricks continue to expand their capabilities and applications. With the development of technology, corundum refractory bricks will play an even more important role in various industries to protect and develop high-temperature industries.
