Chii chinonzi ferritic Stainless simbi?

Simbi isina tsvina chinhu chinoshandiswa zvakanyanya chave chinhu chekutanga mumaindasitiri akasiyana kubva pakuvaka kusvika kune hutano. Asi waiziva here kuti haasi ese masimbi asina tsvina anosikwa akaenzana? Imwe mhando inomira pachena kune yakasarudzika maitiro uye mashandisiro: ferritic simbi isina tsvina. Mune ino blog post, isu tichaongorora mutsauko uripo pakati peferritic simbi isina tsvina nezvimwe mhando dzesimbi isina tsvina, zvayakanakira nezvayakaipira, uye nzira yekuishongedza nemazvo. Saka gara kumashure uye gadzirira kudzidza zvinoshamisa zvimiro zve ferritic simbi isina tsvina.

Chii chinonzi Stainless steel?

Simbi isina tsvina ialloy ine inokwana 10.5% chromium nehukuru, iyo inopa iyo yakasarudzika zvivakwa. Chromium inoumba chidimbu chitete cheokisidhi pamusoro pesimbi isina tsvina, ichiidzivirira kubva pakuora uye ichipa kusaita tsvina, ngura, uye kusachena.

Asi nei izvi zvichikosha? Kusimba kwesimbi isina tsvina kunoita kuti ive chinhu chakakodzera kune akasiyana maapplication uko hutsanana nehutsanana hwakakosha, senge zvirimwa zvekugadzira chikafu kana zvipatara. Pamusoro pezvo, kutaridzika kwakachena uye kushorwa kwesimbi isina tsvina kunoita kuti ive yakakurumbira mumagadzirirwo ezvivakwa sezvivakwa zvemazuva ano kana mabhiriji.

Kune marudzi akasiyana eStainless simbi anowanikwa pamusika nhasi, ane maumbirwo akasiyana anokanganisa kuita kwavo kwese. Mimwe mienzaniso inosanganisira austenitic simbi isina tsvina (inonyanya kuzivikanwa), ferritic Stainless simbi (yatichatarisa pairi gare gare), martensitic Stainless simbi, duplex Stainless simbi, uye kunaya-kuomesa Stainless simbi.

Kunzwisisa kuumbwa kwemhando yega yega yesimbi isina tsvina kunogona kukubatsira kuti usarudze chinhu chakakodzera zvichienderana nezvinodiwa zvekushandisa uku uchichengetedza hupenyu hurefu uye kuvimbika.

Mhando dzakasiyana dzeStainless Steel

Nekuda kwekunakisisa kwayo kusakara, kusimba, uye aesthetics, Stainless simbi chinhu chinoshandiswa zvakanyanya uye chakakurumbira chinowanikwa mumaindasitiri akasiyana. Kubva pakugadzirwa kwemakemikari kunokanganisa kushanda kwayo, kune marudzi akasiyana-siyana esimbi isina tsvina.

Austenitic Stainless simbi ndiyo yakajairika mhando, ine yakakwira nickel uye chromium. Iine simba rakanakisa, kuoma, uye ductility asi inogona kudhura.

Ferritic Stainless simbi ine yakaderera nickel yemukati pane austenitic asi yakakwirira chromium yemukati. Iyo ine magineti uye ine yakanaka corrosion resistance asi haina kuoma seaustenitic.

Martensitic Stainless simbi ine yakakwira kabhoni yemukati ine mwero huwandu hwenickel uye chromium. Iine simba guru asi yakaderera corrosion resistance.

Duplex simbi isina tsvina ine yakasanganiswa microstructure yeferrite uye austenite phases, ine yakakwira chromium yemukati kupfuura mamwe marudzi. Ivo vanopa yakanakisa simba, kuomarara, uye corrosion kuramba pamutengo unonzwisisika.

Kunaya-kuomesa (PH) simbi isina tsvina ine alloys akakosha anogona kuomeswa kuburikidza nekupisa kupisa kuwedzera simba uku uchichengetedza kunaka kwekuora.

Muchidimbu, kunzwisisa mhando dzakasiyana dzesimbi isina simbi iripo kwakakosha pakusarudza iyo chaiyo zvinhu zvichienderana nezvako chaizvo zvekushandisa.

Chii chinonzi ferritic Stainless simbi?

Ferritic Stainless steel imhando yesimbi isina tsvina iyo inonyanya kuumbwa nechromium uye kabhoni kadiki nezvimwe zvinhu. Iyo ine magineti zvivakwa uye yakakwira corrosion kuramba, ichiita kuti ikwane kune akasiyana maapplication akadai semotokari exhaust masisitimu, midziyo yekubikira, uye yekuvharisa yekuvaka.

Imwe yezvakanakira ferritic Stainless simbi ndeye yakanakisa yepamusoro-tembiricha oxidation kuramba. Izvi zvinoita kuti ive chinhu chakanakira maapplication anotarisirwa kuratidzwa kune tembiricha yakakwira, senge cookware kana oveni dzeindasitiri.

Kuenzaniswa nedzimwe mhando dzesimbi dzisina tsvina dzakadai se austenitic kana martensitic simbi isina tsvina, kushandiswa kweferritic stainless simbi kune imwe mukana nekuda kweiyo yakaderera nickel inodiwa pakugadzirwa, zvichikonzera kuderera kwemitengo. Izvi zvinoita kuti zvive zvakanyanya kudhura pasina kupira kuita.

Zvisinei, pasinei nezvakawanda zvakanakira, ferritic Stainless simbi inewo zvimwe zvayakaipira. Imwe dhizaini huru ndeyekuti haigone kuomeswa kuburikidza nekupisa kurapwa, iyo inomisa kushandiswa kwayo mune mamwe maapplication anoda simba rakakwirira.

Kana welding ferritic Stainless simbi, preheating zvinodiwa zvinofanira kufungwa, sezvo kukurumidza kutonhora kubva welding tembiricha kunogona kukonzera embrittlement.

Ferritic Stainless simbi inoramba ichizivikanwa nekuda kwekuenzanisa kwayo pakati pekuita uye kugona.

Zvakanakira uye Zvakaipa zveFerritic Stainless Steel

Ferritic Stainless simbi ine zvakawanda zvakanaka, zvichiita kuti ive sarudzo yakakurumbira mumaindasitiri akasiyana. Imwe yemabhenefiti ayo makuru ndeyekupokana nekuora uye yakakwirira-tembiricha oxidation, ichiita kuti inyatsokodzera kushandiswa munzvimbo dzakafumurwa nezvinhu zvinoparadza.

Kuenzaniswa nemamwe marudzi esimbi isina tsvina, ferritic simbi isina tsvina inewo mukana wekuita mari. Iyo zvakare ine yakanaka magineti zvivakwa, zvichiita kuti ive yakakodzera kune chaiwo maapplication akadai semagetsi emagetsi.

Nekudaro, ferritic Stainless simbi inewo zvimwe zvayakaipira. Zvinogona kunetsa kupinza nekuda kwenjodzi yekunzwa uye kupaza. Pamusoro pezvo, kuoma kwemhando iyi yesimbi kunowanzo kuderera pane iyo yeaustenitic simbi, zvichiita kuti isarambe yakasimba pasi pemamiriro ekurodha.

Uyezve, ferritic Stainless simbi inogona kuita brittle pakudziya kwakaderera, zvichiita kuti isakodzere kushandiswa mukutonhora. Izvo zvakakosha kuti uzive kuti kunyangwe ferritic Stainless simbi ine zvakawanda zvakanakira, kunzwisisa kwayo painogumira kwakakosha kana uchifunga nezve mashandisiro ayo chero application kana chirongwa chinoda kusimba uye kuvimbika kwechimiro.

Welding Nzira yeFerritic Stainless Simbi

Nekuda kweiyo ferritic Stainless simbi yekutsemuka panguva yewelding, kubudirira kugadzira chinhu ichi kunonetsa. Heano mamwe matipi ekuti ungabudirira sei weld ferritic Stainless simbi:

Chekutanga, preheating zvinhu usati welding kwakakosha. Iyi nzira inobatsira kudzikisa njodzi yekutsemuka nekuona kunonoka kutonhora uye kuderedza kushushikana kwekupisa mushure mewelding. Iyo inodiwa preheat tembiricha inoenderana neukobvu uye giredhi yechinhu chiri kusungirirwa.

Chechipiri, kusarudza waya yekuzadza yakakodzera kwakakosha. Ferritic Stainless simbi ine yakakwira zviyo kukura, izvo zvinokanganisa maitiro ayo emuchina. Kushandisa waya yakaderera-kabhoni yekuzadza netitanium kana niobium inogona kubatsira kuderedza kukura kwezviyo uye kunatsiridza kusaora.

Chechitatu, kutora matanho anodiwa panguva yewelding, sekudzora kupisa kwekuisa uye kudzivirira kupisa kwakanyanya, kunogona kuderedza deformation.

Zvichienderana nekushandiswa kana kushandiswa kwemamiriro ezvakaiswa welded simbi isina tsvina, post-weld heat treatment (PWHT) inogonawo kudiwa.

Kugadzirira kwakaringana kusati kwabatanidzwa nekunyatso kusarudzwa kwesimbi yekuzadza uye kutonga panguva yekugadzira welding inova nechokwadi chekubudirira mhedzisiro kana uchishanda ne ferritic Stainless simbi zvinhu.
