Mwamakonda 304 304L Mbale yachitsulo chosapanga dzimbiri
Mawonekedwe a zitsulo zosapanga dzimbiri
1. Weldability
Zogwiritsa ntchito zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana pakuwotcherera.Kalasi ya zinthu zapa tebulo nthawi zambiri safuna kuwotcherera, ndipo imaphatikizanso mabizinesi ena amphika.Komabe, zinthu zambiri zimafuna kuwotcherera kwabwino kwa zida zopangira, monga kalasi yachiwiri, makapu a thermos, mapaipi achitsulo, zotenthetsera madzi, zoperekera madzi, etc.
2. Kukana dzimbiri
Zambiri zosapanga dzimbiri zosapanga dzimbiri zimafuna kukana bwino kwa dzimbiri, monga Class I ndi II tableware, ziwiya zakukhitchini, zotenthetsera madzi, zopangira madzi, ndi zina zambiri. ndi kuthira pakapita nthawi.Chotsani yankho, sambitsani ndi kuumitsa, ndi kuyeza kulemera kwake kuti mudziwe kuchuluka kwa dzimbiri (Zindikirani: Pamene mankhwala apukutidwa, Fe zomwe zili munsalu yotsekemera kapena sandpaper zidzayambitsa dzimbiri pamtunda panthawi yoyesera).
3. Kuchita bwino kwambiri
Masiku ano, zinthu zachitsulo zosapanga dzimbiri nthawi zambiri zimapukutidwa panthawi yopanga, ndipo ndi zinthu zochepa chabe monga zotenthetsera madzi ndi zopangira madzi zopangira madzi sizifunika kupukuta.Chifukwa chake, izi zimafuna kuti kupukuta kwazinthu zopangira ndikwabwino kwambiri.Zinthu zazikulu zomwe zimakhudza magwiridwe antchito a kupukuta ndi izi:
(1) kuwonongeka kwapamtunda kwa zinthu zopangira.Monga kukwapula, pitting, pickling, etc.
(2)Vuto la zipangizo.Ngati kuuma kuli kochepa kwambiri, sikudzakhala kosavuta kupukuta pamene kupukuta (katundu wa BQ si wabwino), ndipo ngati kuuma kuli kochepa kwambiri, zochitika za peel lalanje zimakhala zosavuta kuwonekera pamtunda panthawi yojambula mozama, motero zimakhudza. Mtengo wa BQ.Makhalidwe a BQ okhala ndi kuuma kwakukulu ndi abwino.
(3) Kwa mankhwala ozama kwambiri, madontho ang'onoang'ono akuda ndi RIDGING adzawonekera pamwamba pa malo omwe ali ndi zowonongeka zambiri, motero zimakhudza ntchito ya BQ.
4. Kukana kutentha
Kukana kutentha kumatanthawuza kuti chitsulo chosapanga dzimbiri chikhoza kukhalabe ndi mawonekedwe ake abwino kwambiri a thupi ndi makina pa kutentha kwakukulu.
Mphamvu ya carbon: Carbon imapangidwa mwamphamvu ndikukhazikika muzitsulo zosapanga dzimbiri za austenitic.Zinthu zomwe zimatsimikizira austenite ndikukulitsa dera la austenite.Mphamvu ya carbon kupanga austenite ndi pafupifupi 30 kuwirikiza faifi tambala, ndi carbon ndi interstitial element kuti akhoza kwambiri kuwonjezera mphamvu ya austenitic zosapanga dzimbiri zitsulo kudzera olimba njira kulimbitsa.Mpweya ukhozanso kupititsa patsogolo kukana kwa chitsulo chosapanga dzimbiri cha austenitic mu chloride yokhazikika kwambiri (monga 42% MgCl2 yothetsera kuwira).
Komabe, mu chitsulo chosapanga dzimbiri cha austenitic, kaboni nthawi zambiri imawonedwa ngati chinthu chovulaza, makamaka chifukwa pamikhalidwe ina (monga kuwotcherera kapena kutenthetsa pa 450 ~ 850 ° C) pakukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri, mpweya umatha kulumikizana ndi mpweya mumlengalenga. zitsulo.Chromium imapanga mitundu yambiri ya chromium Cr23C6-mtundu wa carbon compounds, zomwe zimapangitsa kuti chromium ya m'deralo iwonongeke, zomwe zimachepetsa kukana kwa chitsulo, makamaka kukana kwa intergranular corrosion.choncho.Zambiri mwazitsulo zosapanga dzimbiri za chromium-nickel austenitic zomwe zangopangidwa kumene kuyambira m'ma 1960 ndi mitundu ya carbon yotsika kwambiri yokhala ndi mpweya wochepera 0.03% kapena 0.02%.Zingathe kudziwika kuti pamene mpweya wa carbon umachepetsa, mphamvu ya intergranular corrosion yachitsulo imachepa.Pamene okhutira mpweya ndi otsika kuposa 0,02% ndi zotsatira zoonekeratu, ndi zina zatsopano ananenanso kuti mpweya kumawonjezera pitting dzimbiri chizolowezi chromium austenitic zosapanga dzimbiri chitsulo.Chifukwa cha kuvulaza kwa carbon, sikuti mpweya wokhawo uyenera kuyang'aniridwa mochepa momwe mungathere posungunula zitsulo zosapanga dzimbiri za austenitic, komanso pakapita nthawi yotentha, kuzizira komanso kutentha kwa kutentha pofuna kupewa kuwonjezeka kwa carbon. pamwamba pa chitsulo chosapanga dzimbiri ndikupewa chromium carbides Precipitate.
5. Kukana dzimbiri
Pamene kuchuluka kwa maatomu a chromium muchitsulo sikuchepera 12.5%, mphamvu ya electrode ya chitsulo imatha kusinthidwa mwadzidzidzi kuchoka ku kuthekera koyipa kupita ku mphamvu ya electrode yabwino.Pewani kuwonongeka kwa electrochemical.
Kuchita muyezo wa mbale zosapanga dzimbiri
Chitsulo chachitsulo chosapanga dzimbiri chimakhala ndi malo osalala, mapulasitiki apamwamba, kulimba ndi mphamvu zamakina, ndipo sagwirizana ndi dzimbiri ndi ma acid, mpweya wa alkaline, zothetsera ndi zina.Ndi chitsulo cha alloy chomwe sichichita dzimbiri mosavuta, koma chosachita dzimbiri.Chitsulo chachitsulo chosapanga dzimbiri chimatanthawuza mbale yachitsulo yomwe imagonjetsedwa ndi dzimbiri ndi zinthu zopanda mphamvu monga mpweya, nthunzi ndi madzi, pamene mbale yachitsulo yosagwira asidi imatanthawuza mbale yachitsulo yomwe imagonjetsedwa ndi dzimbiri ndi zinthu zowononga mankhwala monga asidi, alkali, ndi mchere.Chitsulo chosapanga dzimbiri chakhalapo kwa zaka zoposa zana kuchokera pamene chinatuluka kumayambiriro kwa zaka za m'ma 1900.
Chitsulo chosapanga dzimbiri nthawi zambiri chimatanthawuza mbale zachitsulo zosapanga dzimbiri ndi mbale zachitsulo zosapanga asidi.Kumayambiriro kwa zaka za m'ma, chitukuko cha mbale zosapanga dzimbiri wayala mfundo zofunika ndi luso maziko chitukuko cha makampani amakono ndi kupita patsogolo sayansi ndi luso.Pali mitundu yambiri yazitsulo zosapanga dzimbiri zomwe zimakhala ndi katundu wosiyana.Pang'onopang'ono wapanga magulu angapo mu chitukuko.
Malinga ndi kapangidwe kake, amagawidwa m'magulu anayi: chitsulo chosapanga dzimbiri cha austenitic, chitsulo chosapanga dzimbiri cha martensitic (kuphatikiza mpweya wowumitsa chitsulo chosapanga dzimbiri), chitsulo chosapanga dzimbiri cha ferritic, ndi chitsulo chosapanga dzimbiri cha austenitic kuphatikiza ferritic duplex.Makina akuluakulu kapena zinthu zina zomwe zili mu mbale yachitsulo zimayikidwa mu mbale ya chromium yosapanga dzimbiri, mbale ya chromium nickel, chromium nickel molybdenum chitsulo chosapanga dzimbiri, mbale yachitsulo yosapanga dzimbiri ya carbon, mbale yachitsulo yosapanga dzimbiri ya molybdenum, mbale yachitsulo yosapanga dzimbiri ya molybdenum, mbale yachitsulo chosapanga dzimbiri. , ndi zina.
Malinga ndi momwe zitsulo zimagwirira ntchito komanso kagwiritsidwe ntchito ka mbale zachitsulo, zimagawidwa kukhala mbale zachitsulo zosapanga dzimbiri za nitric acid, mbale zachitsulo zosapanga dzimbiri za sulfuric acid, zitsulo zosapanga dzimbiri zosapanga dzimbiri, mbale zachitsulo zosapanga dzimbiri, komanso mphamvu zambiri. mbale zitsulo zosapanga dzimbiri.Malinga ndi magwiridwe antchito a mbale yachitsulo, imagawidwa kukhala mbale yachitsulo chosapanga dzimbiri, mbale yopanda maginito yachitsulo chosapanga dzimbiri, mbale yachitsulo yosapanga dzimbiri, mbale yachitsulo yosapanga dzimbiri, ndi zina zambiri. ku mapangidwe a mbale yachitsulo, mawonekedwe a mankhwala a mbale yachitsulo ndi kuphatikiza ziwirizo.
Amagawidwa kukhala chitsulo chosapanga dzimbiri cha martensitic, chitsulo chosapanga dzimbiri cha ferritic, chitsulo chosapanga dzimbiri cha austenitic, chitsulo chosapanga dzimbiri cha duplex ndi mpweya wowumitsa chitsulo chosapanga dzimbiri, etc. kapena kugawidwa m'magulu awiri: chromium chitsulo chosapanga dzimbiri ndi faifi tambala.Zosiyanasiyana Zogwiritsa Ntchito Zomwe zimagwiritsidwa ntchito: zida zamkati ndi mapepala zosinthira kutentha, zida zamakina, zida zopaka utoto, zida zopangira mafilimu, mapaipi, zida zakunja zomanga nyumba m'mphepete mwa nyanja, ndi zina zambiri.
Chitsulo chachitsulo chosapanga dzimbiri chimakhala ndi malo osalala, mapulasitiki apamwamba, kulimba ndi mphamvu zamakina, ndipo sagwirizana ndi dzimbiri ndi ma acid, mpweya wa alkaline, zothetsera ndi zina.Ndi chitsulo cha alloy chomwe sichichita dzimbiri mosavuta, koma chosachita dzimbiri.
Makulidwe a phazi ndi makulidwe okhazikika a mbale yachitsulo chosapanga dzimbiri
Kuchuluka kwa phazi kumatanthauza kuti makulidwe enieni siwosiyana kwambiri ndi makulidwe a chiphunzitso (omwe amatchedwanso makulidwe a label), komwe kuli kusiyana kochepa kolakwika.Ngati makulidwe a zilembo ndi 1.0MM, makulidwe a phazi ofunikira ndi pafupifupi 0.98MM-1.0MM, ndipo makulidwe a phazi akhoza kukhala Amamveka ngati "wokhuthala mokwanira", ndipo makulidwe ake ndi makulidwe amalingaliro.Mapiritsi achitsulo amalembedwa pamene akuchoka ku fakitale, kusonyeza makulidwe a chiphunzitso.Uwu ndiye makulidwe okhazikika.
