Description of corundum mullite castables
Corundum mullite castable is a kind of monolithic refractory material made of mullite aggregate, calcium aluminate cement, silica micropowder, explosion-proof fiber and ultra-fine powder refractory powder. Corundum mullite refractory castables have the common advantages of corundum refractory castables and mullite castables, with high temperature compressive strength, thermal shock resistance and good resistance to structural spalling performance.
Characteristics of corundum mullite castables
High temperature resistance
Corundum mullite castables can withstand extremely high temperatures of up to 1600°C. They can be used in a wide range of applications. It maintains its strength and integrity even after prolonged exposure to high temperatures, making it suitable for use in furnaces, kilns and other high-temperature industrial equipment.
Outstanding Thermal Shock Resistance
Corundum mullite castables are able to withstand rapid temperature changes without cracking or other damage. It is ideally suited for use in equipment with frequent temperature cycling, such as glass manufacturing or heat treatment processes.
High strength and wear resistance
Corundum mullite castables have a high compressive and flexural strength and can resist damage caused by mechanical stress and abrasion.
Erosion resistance
Corundum mullite castables are highly resistant to acid and alkali gases and molten metals. It resists erosion from hot gases and molten metals, extending service life and maintaining structural integrity.
Slag resistance
Corundum mullite castables are resistant to slag attack and do not react with or corrode easily. This makes it suitable for use in metallurgical and glass industry scenarios where slag erosion is a problem.
Easy to install
Corundum mullite castables are easy to install and can be molded to the specific contours of the equipment being lined. It can be applied using a variety of techniques such as casting, gunning and troweling.
Customizable formulations
The composition of corundum mullite castables can be customized to meet the specific requirements of different applications. This makes it possible to optimize performance and cost-effectiveness for each specific use.
Applications for corundum mullite castables
Steelmaking
Corundum mullite castables are used for lining the interior walls of electric arc furnaces, ladles, continuous casting tanks and other steelmaking equipment. It helps protect the furnace lining from high temperatures and corrosive environments, ensuring reliable and efficient operation.
Non-ferrous metal production
Corundum mullite castables are also used in the production of non-ferrous metals such as copper, aluminum and nickel. Used in the lining of furnaces, converters and other processing equipment, these castables help to maintain the integrity of the furnace lining and improve overall processing efficiency.
Incineration and Waste Management
Corundum mullite castables are used in the interior walls of incinerators and other waste management equipment to help withstand the high temperatures and corrosive environments of the combustion process.
Glass Manufacturing
Corundum mullite castables are used in glass furnaces and other high-temperature processing equipment in the glass industry. These castables help maintain the integrity of the furnace lining and improve processing efficiency.
Petrochemical and Chemical Processing
Corundum mullite castables are used for lining reactors, regenerators and other high temperature processing equipment in the petrochemical and chemical industries. Corundum mullite castables help protect equipment from corrosion and high temperature environments, ensuring reliable and efficient operation.
