With the continuous improvement of modern industry's requirements for high-temperature material performance, metallurgical heat-resistant steel has become a key material in the fields of energy, chemical industry, aerospace, etc. with its excellent high-temperature strength, oxidation resistance and creep resistance. This article will analyze the core characteristics of metallurgical heat-resistant steel and its application value from yon pèspektiv teknik .
Avantaj debaz asye métallurgique ki reziste nan chalè manti nan estabilite wo-tanperati li yo . pa ajoute eleman alyaj tankou CHROMIUM, nikèl, ak MOLYBDENUM, chalè ki reziste asye ka yon fermités oxid ki gen plis. Plis pase 12% ka kenbe alontèm estabilite nan yon anviwònman pi wo a 800 degre, pandan y ap nikèl ki baze sou chalè ki reziste asye ka kenbe entegrite estriktirèl nan pi wo tanperati . karakteristik sa a fè li lajman itilize nan gwo tanperati-eleman tankou lam turbine ak tiyo chodyè .}}
An tèm de pwopriyete mekanik, asye metalurji ki reziste chalè te siyifikativman amelyore rezistans fluaj li yo nan microalloying ak pwosesis tretman chalè optimize {{1} Gen kèk pwodwi asye-wo fen chalè ki reziste nan 600 degre ka rive jwenn plis pase 100MPa, satisfè bezwen yo nan kondisyon travay ekstrèm .
Pwosesis adaptabilite se yon lòt rekò nan asye metalurji ki reziste chalè . Aplikasyon an nan teknoloji modèn fondri tankou k ap fonn Vacuum (VIM) ak elèktroslag renovasyon (ESR) te redwi anpil kontni an nan (TMCP) Pèmèt asye gen bon andirans pandan w ap kenbe gwo fòs, rezoud pwen doulè nan gwo fragilite nan asye tradisyonèl ki reziste chalè .
Environmental protection and economy are also the key directions of heat-resistant steel technology development. By optimizing the composition design, the new generation of heat-resistant steel reduces the amount of rare metals and reduces production costs while ensuring performance. In addition, some heat-resistant steel products can be recycled and reused, which is in line with the industrial trend of sustainable development.
Nan lavni an, ak zouti nan nouvo teknoloji materyèl, asye metalurji ki reziste chalè ap montre pi gwo potansyèl nan pi wo tanperati ak kondisyon travay pi konplèks, epi kontinye ankouraje ekipman endistriyèl yo devlope nan yon direksyon ki nan efikasite segondè ak lavi long .
