Metallurgical heat-resistant steel is widely used in high-temperature industrial fields such as boilers, heat treatment equipment, and aircraft engines due to its excellent high-temperature strength, oxidation resistance, and creep resistance.However, the performance of heat-resistant steel may gradually decline after long-term operation in a high-temperature environment, so scientific maintenance and care are essential. Este artigo apresentará os pontos de manutenção diária do aço resistente ao calor metalúrgico para ajudar os usuários a prolongar sua vida útil e garantir a operação estável do equipamento .
1. limpeza e inspeção regular
If oxides, carbon deposits, or other impurities accumulate on the surface of heat-resistant steel for a long time, it may affect its thermal conductivity and corrosion resistance. It is recommended to clean surface dirt regularly, especially for equipment in high-temperature working environments. At the same time, regularly check whether the heat-resistant steel parts have cracks, deformations, or signs of corrosão e detectar e lidar prontamente com possíveis problemas para evitar mais danos .
2. Controle temperatura operacional e tensão térmica
Although heat-resistant steel has high high-temperature resistance, long-term over-temperature operation may still cause material performance degradation. The operating temperature should be strictly controlled according to the equipment design parameters to avoid frequent temperature fluctuations to reduce the damage to the material caused by thermal stress. During the start-up and shutdown of the equipment, try to use a slow heating or cooling method to avoid thermal Fadiga causada por refrigeração rápida e aquecimento .
3. Seleção razoável de medidas de lubrificação e proteção
In high temperature environments, the friction parts of heat-resistant steel parts may require special lubricants to reduce wear. High temperature resistant and anti-oxidation lubricating products should be selected and replenished or replaced regularly. In addition, for heat-resistant steel exposed to corrosive environments, high temperature resistant anti-corrosion coatings can be considered to enhance their corrosion Resistência .
4. soldagem e reparo corretos
If heat-resistant steel parts are damaged, special attention should be paid during welding repair. Heat-resistant steel welding materials that match the parent material should be selected, and appropriate welding processes should be used to avoid material performance degradation due to improper welding. After repair, it is recommended to perform appropriate heat treatment to restore the mechanical properties of the material.
Através de manutenção e cuidados científicos, o desempenho do aço metalúrgico resistente ao calor pode ser efetivamente garantido, melhorando assim a eficiência da operação do equipamento e reduzindo os custos de manutenção .
