Chitsulo kwenikweni ndi aloyi yachitsulo ndi kaboni, koma nthawi zambiri, zomwe zimakhala ndi kaboni zimakhala zosakwana 2%. Sizochuluka, koma kaboni ndiye chinthu chofunikira kwambiri chomwe chimakhudza mphamvu zake ndi kuuma kwake. Chitsulo chosapanga dzimbiri ndi aloyi wokhala ndi chitsulo, chromium, faifi tambala, ndipo nthawi zina zinthu zina monga molybdenum. Chromium imapangitsa chitsulo chosapanga dzimbiri kuti zisawonongeke ndi dzimbiri.

• Chitsulo cha Carbon: Zigawo zazikuluzikulu ndi chitsulo ndi kaboni, zomwe zimakhala ndi mpweya kuyambira 0.2% mpaka 2.1%. Zinthu zina, monga manganese, silicon, phosphorous, ndi sulfure, zikhozanso kukhalapo pang'ono.
• Chitsulo chosapanga dzimbiri: Imakhala ndi chitsulo, kaboni, ndi 10.5% chromium (nthawi zina ndi faifi tambala). Kuphatikizika kwa chromium ndikofunikira chifukwa imagwira ntchito ndi okosijeni mumlengalenga kuti ipange wosanjikiza wa chromium oxide, womwe umapatsa chitsulo chosapanga dzimbiri kuti zisachite dzimbiri komanso zosachita dzimbiri.

Zosiyana mu Properties

Chifukwa cha kusiyana kwake, zitsulo zosapanga dzimbiri ndi zitsulo zimakhalanso ndi zinthu zosiyana kwambiri. Mosiyana ndi chitsulo chokhazikika, chitsulo chosapanga dzimbiri chimakhala ndi chromium, yomwe imapanga wosanjikiza woteteza wa oxide womwe umalepheretsa dzimbiri ndi dzimbiri.

Ponena za makhalidwe okongola, chitsulo chosapanga dzimbiri chimapukutidwa komanso chamakono kuposa chitsulo chokhazikika. Mitundu yambiri yazitsulo za carbon ndi maginito, zomwe zingakhale zopindulitsa pazinthu zina. Koma chitsulo chosapanga dzimbiri, ngati 304 kapena 316, sichikhala ndi maginito.

Chitsulo VS Stainless Steel: Njira Zopangira

Njira zopangira zitsulo ndi zitsulo zosapanga dzimbiri zimaphatikizapo magawo angapo opangira kuti asinthe zida kukhala zomaliza. Nazi njira zofunika kwambiri zopangira zitsulo ndi zitsulo zosapanga dzimbiri:

Njira Zopangira Zitsulo

A. Kupanga zitsulo

Panthawi imeneyi, chitsulo, coke (carbon), ndi fluxes (laimu) amalowetsedwa mu ng'anjo yoyaka moto. Kutentha kwakukulu kumasungunula chitsulo, ndipo mpweya umachepetsa chitsulo, kupanga chitsulo chosungunuka, chomwe chimatchedwa chitsulo chotentha.

B. Kupanga zitsulo

Tengani chitsanzo cha ng'anjo ya oxygen (BOF). Njira ya BOF imaphatikizapo kulipiritsa zitsulo zotentha za ng'anjo kapena DRI mu chotengera chosinthira. Mpweya woyeretsedwa kwambiri umawomberedwa m'ngalawamo, kutulutsa zonyansa ndikuchepetsa mpweya wa carbon kuti upange zitsulo.

C. Kuponya Mopitiriza

Kuponyera kosalekeza ndi pamene zitsulo zosungunuka zimaponyedwa muzinthu zomwe zatha, monga slabs, billets, kapena blooms. Zimaphatikizapo kuthira chitsulo chosungunuka mu nkhungu yoziziritsidwa ndi madzi ndikuchilimbitsa kukhala chingwe chosalekeza. Kenako chingwecho chimadulidwa mu utali wofunidwa.

D. Kupanga ndi Kupanga

Kugudubuza: Zopangira zitsulo zotsirizidwa kuchokera pakuponyedwa kosalekeza zimakulungidwa mu mphero zotentha kapena zozizira kuti zichepetse makulidwe, kuwongolera mawonekedwe apamwamba, ndikukwaniritsa miyeso yomwe mukufuna.

Kupanga: Kupanga ndi njira yomwe chitsulo chotenthetsera chimapangidwa pogwiritsa ntchito mphamvu zopondereza. Amagwiritsidwa ntchito popanga zigawo zomwe zimafuna mphamvu zambiri komanso kulimba.

Njira Zopangira Zitsulo Zosapanga dzimbiri

A. Kupanga Zitsulo Zosapanga dzimbiri

Kusungunula: Chitsulo chosapanga dzimbiri chimapangidwa ndi kusungunula kuphatikiza kwachitsulo, chromium, faifi tambala, ndi zinthu zina zophatikizika mu ng'anjo zamagetsi zamagetsi kapena ng'anjo zolowera.

Kuyenga: Chitsulo chosapanga dzimbiri chosungunula chimadutsa njira zoyenga monga argon oxygen decarburization (AOD) kapena vacuum oxygen decarburization (VOD) kuti asinthe kapangidwe kake, kuchotsa zonyansa, ndikuwongolera zomwe mukufuna.

B. Kupanga ndi Kupanga

Kugudubuzika Kotentha: Zoyikapo zitsulo zosapanga dzimbiri kapena ma slabs amatenthedwa ndikudutsa mphero zotentha kuti zichepetse makulidwe ndikuzipanga kukhala zomangira, mapepala, kapena mbale.

Cold Rolling: Kugudubuzika kozizira kumachepetsanso makulidwe a chitsulo chosapanga dzimbiri komanso kumapangitsa kuti pakhale malo ofunikira. Komanso bwino makina katundu ndi dimensional molondola.

C. Chithandizo cha Kutentha

Annealing: Chitsulo chosapanga dzimbiri chimalowa mkati, njira yochizira kutentha, kuti ichepetse kupsinjika kwamkati ndikuwongolera ductility, machinability, ndi kukana dzimbiri.

Kuzimitsa ndi Kutentha: Zitsulo zina zosapanga dzimbiri zimadutsa njira zozimitsira ndi kutenthetsa kuti ziwonjezere mphamvu zawo zamakina, monga kuuma, kulimba, ndi mphamvu.

D. Kumaliza Njira

Pickling: Pamalo achitsulo chosapanga dzimbiri amatha kuzifutsa mu njira ya asidi kuti achotse sikelo, ma oxides, ndi zowononga zina zapamtunda.

Passivation: Passivation ndi mankhwala omwe amapangitsa kuti chitsulo chosapanga dzimbiri chisawonongeke popanga chitsulo chosapanga dzimbiri choteteza oxide pamwamba.

Njira zomwe zimagwiritsidwa ntchito zimatha kusiyanasiyana kutengera mtundu wachitsulo chomwe mukufuna kapena chitsulo chosapanga dzimbiri komanso kagwiritsidwe ntchito komaliza.

Chitsulo VS Chitsulo chosapanga dzimbiri: Mphamvu ndi Kukhalitsa

Kulimba kwachitsulo kumadalira makamaka zomwe zili ndi kaboni ndi zinthu zina zophatikizika, monga manganese, silicon, ndi kufufuza kuchuluka kwa zigawo zosiyanasiyana. Zitsulo zolimba kwambiri, monga zitsulo zotsika kwambiri (HSLA) ndi zitsulo zolimba kwambiri (AHSS), zimagwiritsidwa ntchito pazovuta monga kupanga ndi kupanga magalimoto. Chitsulo chosapanga dzimbiri nthawi zambiri chimakhala ndi mphamvu zochepa kuposa chitsulo, koma chimakhalabe ndi mphamvu zokwanira pazinthu zambiri.

Chitsulo VS Chitsulo Chosapanga dzimbiri : Kuyerekeza Mtengo

Pankhani ya mtengo, zitsulo nthawi zambiri zimakhala zotsika mtengo kusiyana ndi zitsulo zosapanga dzimbiri, zomwe zimapangitsa kuti pakhale chisankho chothandizira bajeti pama projekiti ambiri, popeza chitsulo chosapanga dzimbiri chimakhala chokwera mtengo kupanga kuposa chitsulo, ponse pakupanga ndi kupanga.

Chitsulo VS Chitsulo chosapanga dzimbiri : Mapulogalamu

Chitsulo ndi chitsulo chosapanga dzimbiri ndi zida zosunthika zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Chitsulo, chokhala ndi mphamvu komanso kulimba kwake, chimapezeka nthawi zambiri pantchito zomanga monga milatho, nyumba, ndi zomangamanga. Ndilo kusankha kotchuka kwa zigawo zamapangidwe.

Chitsulo chosapanga dzimbiri cholimbana ndi dzimbiri chimapangitsa kukhala koyenera kumalo komwe kumakhala chinyezi kapena mankhwala. Izi zimapangitsa chitsulo chosapanga dzimbiri kukhala chisankho chapamwamba pazida zakukhitchini, zida zopangira chakudya, zida zamankhwala, ndi zodzikongoletsera.

M'makampani opanga magalimoto, zida zonse ziwiri zimagwira ntchito yofunika kwambiri - chitsulo chimagwiritsidwa ntchito nthawi zambiri pamafelemu agalimoto chifukwa cha mphamvu zake, pomwe chitsulo chosapanga dzimbiri chimagwiritsidwa ntchito potulutsa mpweya chifukwa chokana kutentha kwambiri komanso dzimbiri.

Mapeto

Kusiyana kwakukulu pakati pa chitsulo chokhazikika ndi chitsulo chosapanga dzimbiri ndikukana dzimbiri. Ngakhale chitsulo chokhazikika chimakhala champhamvu koma chimakonda dzimbiri, chitsulo chosapanga dzimbiri chimatha kukana dzimbiri chifukwa cha kukhalapo kwa chromium, yomwe imapanga wosanjikiza woteteza oxide. Kutengera ndikugwiritsa ntchito, mutha kusankha zinthu zoyenera kuti muchepetse magwiridwe antchito ndi mtengo wake.
