Chiyambi cha Duplex Stainless Steel

Zitsulo zosapanga dzimbiri ziwiri, zodziwika bwino chifukwa chophatikiza makhalidwe a austenitic ndi ferritic, zimayimira umboni wa kusintha kwa metallurgy, zomwe zimapereka mgwirizano wa zabwino komanso kuchepetsa zovuta zomwe zilipo, nthawi zambiri pamtengo wotsika.

Kumvetsetsa Chitsulo Chosapanga Dziwe cha Duplex:

Chofunika kwambiri pa chitsulo chosapanga dzimbiri cha duplex ndi kapangidwe kake ka magawo awiri, komwe nthawi zambiri kumakhala ndi kusakaniza koyenera kwa austenite ndi ferrite, zomwe zimapangitsa kuti pakhale mgwirizano wabwino komanso kuchepetsa zofooka. Kapangidwe ka zitsulo, ngakhale zimadalira mtundu wake, nthawi zambiri kamakhala ndi kaboni, manganese, silicon, chromium, nickel, phosphorous, ndi sulfure, ndi zowonjezera zina monga molybdenum, nayitrogeni, ndi mkuwa zomwe zimapangitsa kuti zinthuzo zisinthe.

Mbiri Yakale ya Chitsulo Chosapanga Dzimbiri cha Duplex:

Kubadwa kwa ma alloy osapanga dzimbiri awiri kunayambira m'malingaliro a m'ma 1920, zomwe zinafika pachimake pa ntchito zopanga zinthu zooneka m'ma 1930. Poyamba zinkangogwiritsidwa ntchito popanga zinthu zopangidwa ndi chitsulo ndi ntchito zapadera chifukwa cha kuchuluka kwa kaboni, kupita patsogolo kwa decarburization kumapeto kwa zaka za m'ma 1960 kunayambitsa nthawi yatsopano, zomwe zinathandiza kupanga ma alloy otsika a kaboni okhala ndi chromium ndi nickel yokonzedwa bwino, motero kukonza bwino pakati pa ferrite ndi austenite. Chizindikiro cha njira yosinthirayi ndi Duplex 2205, alloy yoyambira pakati pa zaka za m'ma 1970 yomwe ikupitilizabe kukhala yofunika chifukwa cha kukana kwake dzimbiri poyerekeza ndi ma grade a austenitic wamba.

Ubwino wa Duplex Stainless Steel:

Ngakhale kuti ndi gawo laling'ono pamsika wa zitsulo zosapanga dzimbiri, ma duplex alloys amapereka zabwino zambiri poyerekeza ndi ma austenitic ndi ferritic achikhalidwe. Zabwino kwambiri pakati pa izi ndi mphamvu yowonjezera, kulimba kowonjezereka, komanso kusinthasintha, komwe kumawoneka ngati chizindikiro chodziwika bwino cha kukana dzimbiri, komwe kumapikisana, ngati sikuposa, ndi ma austenitic grade. Kuphatikiza apo, kugwiritsa ntchito bwino ndalama zomwe zimapezeka mu duplex steel, chifukwa chogwiritsa ntchito bwino zinthu zophatikiza, zimapangitsa kuti ikhale chisankho chosangalatsa pa ntchito zosiyanasiyana.

Kugwiritsa ntchito Duplex Stainless Steel:

Kusinthasintha kwa chitsulo chosapanga dzimbiri cha duplex kumaonekera m'mafakitale ndi m'madera osiyanasiyana, chifukwa cha kukana dzimbiri, mphamvu zake zowonjezera, komanso mtengo wake wotsika. Makamaka, ntchito za m'mphepete mwa nyanja ndi pafupi ndi gombe, kuphatikizapo kuboola mafuta, kuchotsa mchere m'madzi, ndi kuyeretsa madzi, ndizo zomwe zimapindula kwambiri ndi luso la chitsulo cha duplex. Mofananamo, ntchito yake imafikira pa kukonza mankhwala, kugwiritsa ntchito panyanja, zida zowongolera kuipitsa, ndi ntchito zomanga, zomwe zikuwonetsa kupezeka kwake kulikonse m'mafakitale amakono.
