Munzvimbo yesainzi yemidziyo, rudzi rutsva rwesimbi isina simbi inozivikanwa se duplex Stainless simbi iri kugadzira masaisai.Iyi inoshamisa alloy ine yakasarudzika chimiro, ine ferrite chikamu uye austenite chikamu chega chega accounting hafu yechimiro chayo chakaomeswa.Chinotonyanya kushamisa inyaya yekuti chikamu chidiki chemukati chinogona kusvika kune chinokatyamadza 30%.
Duplex Stainless simbi inoratidza yakanakisa mechaniki zvivakwa nekuda kwezvikamu zvayo zviviri.Iine yakaderera kabhoni yemukati, iyo chromium yemukati inotangira pa18% kusvika 28%, nepo nickel yemukati inomira pakati pe3% ne10%.Pamusoro pezvinhu izvi zvakakosha, mamwe marudzi e duplex simbi isina tsvina anosanganisirawo alloying zvinhu zvakaita se molybdenum (Mo), mhangura (Cu), niobium (Nb), titanium (Ti), uye nitrogen (N).
Hunhu hunoshamisa hwesimbi iyi huri mukuti inobatanidza hunhu hwakanakisa hwezvose austenitic uye ferritic simbi isina tsvina.Kusiyana nemumwe wayo weferrite, duplex simbi isina tsvina inozvirumbidza yakakwira plastiki uye kuoma.Pamusoro pezvo, inoratidza kuramba kunoshamisa kushushikana nekupwanya kwecorrosion, zvichiita kuti ive yakanyanya kudiwa kune akasiyana maapplication.
Chimwe chinhu chakakosha chinosiyanisa duplex simbi isina tsvina kuramba kwayo kugomba corrosion, inova rudzi rwekuora kunowanikwa munzvimbo dzakaoma semugungwa nemakemikari ekugadzira maindasitiri.Uku kuramba kwecorrosion kunogona kuverengerwa kune alloy's yakakwira chromium uye molybdenum zvirimo zvichienzaniswa neyechinyakare simbi isina tsvina.
Iyo yakasarudzika microstructure ye duplex Stainless simbi inowedzera kusimba kwayo, ichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa.Inowana kushandiswa kwakawanda mumaindasitiri anoda zvinhu zvakasimba uye zvisingadziviriri, zvinosanganisira oiri yekumahombekombe uye kuongorora gasi, zvidyarwa zvekubvisa salination, kugadzira makemikari, uye zvifambiso zvezvifambiso.
Uyezve, kusimba kwesimbi iyi kunogonesa magadzirirwo akareruka uye asingadhure, achibvumira maindasitiri kuti awane kunyatsoshanda.Kupokana kwayo kwakasiyana nekuora kwenzvimbo kunovimbisa hupenyu hurefu hwezvishandiso uye zvimiro, kuderedza mari yekugadzirisa mukufamba kwenguva.
Mumakore achangopfuura, kudiwa kwe duplex simbi isina simbi kwakaona kuwedzera kukuru, nevagadziri vachigadzira mamakisi matsva kuti aenderane kune akasiyana mashandisirwo.Zviitiko izvi zvinovavarira kukwidziridza zvivakwa zvakaita senge corrosion resistance, simba, uye weldability, zvichiwedzera kuwedzera simbi inogona kushandiswa.
Nekuenderera mberi nekutsvagisa uye kusimudzira, ramangwana re duplex simbi isina tsvina rinotaridzika kuvimbisa.Masayendisiti uye mainjiniya vanoramba vachitsvaga nzira dzekusimudzira hunhu hwayo uye kuwedzera kushanda kwayo kune akasiyana maindasitiri.
Sezvo maindasitiri achivavarira kuita zvinogoneka, duplex Stainless simbi inopa mhinduro inoshanda nekuda kwehupenyu hwayo hurefu, kudzokorodza, uye kushomeka kwekuda kwekugadzirisa.Iyi inoshamwaridzana nemamiriro ekunze inoiisa semukwikwidzi anotyisa munhangemutange yezvigadzirwa zvinogara.
Muchidimbu, duplex Stainless simbi inomiririra kubudirira kunoshamisa muzvinhu zvesainzi, kubatanidza zvakanakisa zve austenitic uye ferritic Stainless simbi.Nezvimiro zvayo zvemuchina, kupokana nemhando dzakasiyana dzekuora, uye kuwedzera kudiwa mumaindasitiri, alloy iyi yekuvandudza yakagadzirira kushandura nzira yatinosvika nayo magadzirirwo ezvimiro uye mashandisirwo emaindasitiri.
