Chiyambi cha Duplex Stainless Steel

Zitsulo zosapanga dzimbiri za Duplex, zodziwika chifukwa chophatikiza mikhalidwe ya austenitic ndi ferritic, zimakhala ngati umboni wa kusinthika kwazitsulo, zomwe zimapereka zabwino zambiri kwinaku zimachepetsa zovuta zomwe zimachitika, nthawi zambiri pamitengo yopikisana.

Kumvetsetsa Duplex Stainless Steel:

Pakatikati pa chitsulo chosapanga dzimbiri cha duplex ndi mawonekedwe ake amitundu iwiri, omwe amakhala ndi kusakanikirana koyenera kwa austenite ndi ferrite, zomwe zimabweretsa symbiosis yamakhalidwe abwino ndikuchepetsa kufooka. Zomwe zimapangidwa ndi zitsulo, ngakhale zimatengera kalasi inayake, nthawi zambiri zimaphatikiza kaboni, manganese, silicon, chromium, faifi tambala, phosphorous, ndi sulfure, zokhala ndi zowonjezera monga molybdenum, nayitrogeni, ndi mkuwa zomwe zimayenganso zinthuzo.

Mbiri Yakale ya Duplex Stainless Steel:

Mawonekedwe a duplex zosapanga dzimbiri aloyi amachokera ku zongopeka zama 1920s, zomwe zidafika pachimake pakupanga zowoneka bwino m'ma 1930s. Poyamba ankangopanga kupanga ndi kugwiritsa ntchito mwapadera chifukwa cha kuchuluka kwa mpweya, kupita patsogolo kwa decarburization pofika kumapeto kwa zaka za m'ma 1960 kunalengeza nyengo yatsopano, kuthandizira kaphatikizidwe ka aloyi a carbon otsika okhala ndi chromium ndi faifi tambala, motero amayenga bwino pakati pa ferrite ndi austenite. Chizindikiro cha chisinthikochi ndi Duplex 2205, kagawo kakang'ono koyambira pakati pa zaka za m'ma 1970 komwe kukupitilizabe kufunikira chifukwa cha kukana kwa dzimbiri kwapamwamba kwambiri ndi magiredi odziwika bwino a austenitic.

Ubwino wa Duplex Stainless Steel:

Ngakhale ndi gawo laling'ono la msika wazitsulo zosapanga dzimbiri, ma aloyi a duplex amapereka zabwino zambiri poyerekeza ndi anzawo achikhalidwe austenitic ndi ferritic. Chodziwika bwino pakati pa maubwinowa ndi kulimba kwamphamvu, kulimba kokulirapo, komanso ductility, kukana kwa dzimbiri komwe kukuwonekera ngati chizindikiro chodziwikiratu, kupikisana, ngati sikuposa, kumagiredi austenitic. Kuphatikiza apo, kutsika mtengo komwe kumakhala mu duplex chitsulo, chifukwa chogwiritsa ntchito mwanzeru ma alloying, kumapangitsa kuti ikhale chisankho chofunikira pamagwiritsidwe osiyanasiyana osiyanasiyana.

Kugwiritsa Ntchito Duplex Stainless Steel:

Kusinthasintha kwa chitsulo chosapanga dzimbiri chopangidwa ndi duplex kumamveka bwino m'mafakitale ndi madambwe osiyanasiyana, chifukwa cha kulimba kwake kwa nyenyezi, kulimba kwamphamvu, komanso kutsika mtengo kwake. Makamaka, ntchito za m'mphepete mwa nyanja ndi pafupi ndi gombe, kuphatikizapo kukumba mafuta, kuchotsa mchere, ndi kuyeretsa madzi, ndizo zomwe zimapindula kwambiri ndi luso la duplex steel. Momwemonso, ntchito yake imafikira pakukonza mankhwala, kugwiritsa ntchito panyanja, zida zowongolera kuipitsidwa, ndi ntchito zomanga, kutsimikizira kupezeka kwake paliponse m'mafakitale amakono.
