Kufufuza Makhalidwe Amagetsi a 304 ndi 316 Stainless Steel.

Posankha giredi yachitsulo chosapanga dzimbiri (SS) kuti mugwiritse ntchito kapena chofananira, ndikofunikira kuganizira ngati maginito akufunika.Kuti mupange chisankho mwanzeru, ndikofunikira kumvetsetsa zomwe zimatsimikizira ngati chitsulo chosapanga dzimbiri chili ndi maginito kapena ayi.

Zitsulo zosapanga dzimbiri ndi zitsulo zopangidwa ndi chitsulo zomwe zimadziwika bwino chifukwa chosachita dzimbiri.Pali mitundu yosiyanasiyana ya zitsulo zosapanga dzimbiri, zomwe magulu oyambira amakhala austenitic (mwachitsanzo, 304H20RW, 304F10250X010SL) ndi ferritic (yomwe imagwiritsidwa ntchito kwambiri pamagalimoto, zida zakukhitchini, ndi zida zamakampani).Maguluwa ali ndi mitundu yosiyanasiyana ya mankhwala, zomwe zimapangitsa kuti azisiyana ndi maginito.Zitsulo zosapanga dzimbiri za ferritic zimakonda kukhala maginito, pomwe zitsulo zosapanga dzimbiri za austenitic sizikhala.Maginito a chitsulo chosapanga dzimbiri cha ferritic amachokera pazifukwa ziwiri zazikulu: chitsulo chake chokhala ndi chitsulo chochuluka komanso kamangidwe kake.

Kusintha kuchoka ku Non-Magnetic kupita ku Magnetic Phases mu Stainless Steel

Onse304ndi 316 zitsulo zosapanga dzimbiri zimagwera pansi pa gulu la austenitic, zomwe zikutanthauza kuti zikazizira, chitsulo chimasunga mawonekedwe ake a austenite (gamma iron), gawo lopanda maginito.Magawo osiyanasiyana achitsulo cholimba amafanana ndi mawonekedwe a kristalo.M'zitsulo zina zachitsulo, gawo lachitsulo chotentha kwambirili limasintha kukhala gawo la maginito panthawi yozizira.Komabe, kukhalapo kwa nickel muzitsulo zosapanga dzimbiri kumalepheretsa kusintha kwa gawoli pamene aloyiyo amazizira mpaka kutentha.Zotsatira zake, chitsulo chosapanga dzimbiri chimawonetsa mphamvu ya maginito yokwera pang'ono kuposa zida zopanda maginito, ngakhale imakhalabe pansi pa zomwe zimatengedwa kuti ndi maginito.

Ndikofunika kudziwa kuti simuyenera kuyembekezera kuyeza kutsika kwamphamvu kwa maginito pachidutswa chilichonse cha 304 kapena 316 chitsulo chosapanga dzimbiri chomwe mungakumane nacho.Njira iliyonse yomwe imatha kusintha mawonekedwe a kristalo wachitsulo chosapanga dzimbiri imatha kupangitsa kuti austenite isinthe kukhala ferromagnetic martensite kapena ferrite mitundu yachitsulo.Njira zoterezi zimaphatikizapo kugwira ntchito kozizira ndi kuwotcherera.Kuphatikiza apo, austenite imatha kusandulika kukhala martensite pamatenthedwe otsika.Kuti muwonjezere zovuta, maginito a ma alloys awa amakhudzidwa ndi kapangidwe kake.Ngakhale m'mitundu yovomerezeka yamitundu yosiyanasiyana ya nickel ndi chromium, kusiyana kowoneka bwino kwa maginito kumatha kuwonedwa pa aloyi inayake.

Mfundo Zothandiza Pochotsa Tinthu Zachitsulo Zosapanga dzimbiri

Onse 304 ndi316 chitsulo chosapanga dzimbirikuwonetsa mawonekedwe a paramagnetic.Chifukwa chake, tinthu ting'onoting'ono, monga mabwalo okhala ndi mainchesi oyambira pafupifupi 0.1 mpaka 3mm, amatha kukokeredwa ku zolekanitsa zamphamvu zamaginito zomwe zimayikidwa mkati mwa mtsinje wamankhwala.Kutengera kulemera kwawo ndipo, koposa zonse, kulemera kwawo poyerekeza ndi mphamvu ya kukopa kwa maginito, tinthu tating'onoting'ono timeneti timamatira ku maginito panthawi yopanga.

Pambuyo pake, tinthu tating'ono ting'onoting'ono titha kuchotsedwa bwino panthawi yoyeretsa maginito.Kutengera zomwe tawona, tapeza kuti 304 zitsulo zosapanga dzimbiri zitha kusungidwa mumayendedwe ake poyerekeza ndi 316 zitsulo zosapanga dzimbiri.Izi zimatheka chifukwa cha chitsulo chosapanga dzimbiri cha 304 chokwera pang'ono, chomwe chimapangitsa kuti igwirizane ndi njira zolekanitsa maginito.
