Iron chromium aluminum strip has the advantages of high temperature resistance, oxidation resistance, corrosion resistance, high electrical resistivity, and low coefficient of expansion. Therefore, it has a wide range of applications in multiple fields, mainly including the following aspects:
-Electric heating field
-Heating element: Iron chromium aluminum strip is widely used in the manufacturing of heating elements for various industrial electric furnaces, household ovens, electric heaters, etc. due to its high electrical resistivity and good high temperature resistance. In industrial electric furnaces, it can work stably in high temperature environments, providing the required heat for processes such as metal heat treatment and glass annealing.
-Heating wire: It is a common heating component in electronic devices, such as auxiliary heating wires on computer CPU heat sinks and heating components in some small heating devices. Heating wires made of iron chromium aluminum strip can quickly heat up, convert electrical energy into thermal energy, and meet the heating needs of the equipment.
-Metallurgical field
-Thermocouple protection tube: Iron chromium aluminum strip is commonly used to manufacture thermocouple protection tubes in temperature measurement systems in the metallurgical industry. It can withstand harsh environments such as high temperatures and corrosive atmospheres, protect thermocouples from damage, and ensure the accuracy and stability of temperature measurement.
-Continuous temperature sensor for molten steel: In the process of steel production, real-time and accurate measurement of the temperature of molten steel is required. Iron chromium aluminum strip can be used as an important material for continuous temperature sensors of molten steel. Its high temperature resistance and oxidation resistance enable it to work stably for a long time in the high-temperature environment of molten steel, providing accurate data for temperature control in the steel production process.
-Other fields
-Automobile exhaust purification: Iron chromium aluminum strip can be used as a carrier material in the automobile exhaust purification device. It has a large specific surface area and good high temperature resistance, and can load catalysts to promote the oxidation-reduction reactions of harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides in automobile exhaust, converting them into harmless carbon dioxide, water, and nitrogen, thereby reducing the pollution of automobile exhaust to the environment.
-Aerospace : In the aerospace field, iron chromium aluminum strip can be used to manufacture some high-temperature resistant components in aircraft engines, such as insulation components for combustion chambers and protective coatings for engine blades. Its excellent high temperature resistance, oxidation resistance, and corrosion resistance can ensure the normal operation of these components under extreme working conditions, improving the reliability and efficiency of the engine.
-Industrial filtration: Iron chromium aluminum strip can be used to make various filtering elements for liquid and gas filtration in industries such as chemical, petroleum, and pharmaceutical. Its corrosion resistance and high temperature resistance enable it to be used for a long time in harsh working environments, effectively filtering out impurities and particles, ensuring product quality and production process stability.
