1. Katundu Wamakina a Zitsulo Zosapanga dzimbiri
Zofunikira zamakina nthawi zambiri zimaperekedwa pogula zitsulo zosapanga dzimbiri.Zochepa zamakina zimaperekedwanso ndi miyezo yosiyanasiyana yokhudzana ndi zinthu ndi mawonekedwe azinthu.Kukumana ndi zida zamakina izi zikuwonetsa kuti zinthuzo zidapangidwa bwino kuti zikhale ndi dongosolo loyenera.Mainjiniya amatha kugwiritsa ntchito zinthuzo molimba mtima m'mapangidwe omwe amakumana ndi zolemetsa zotetezedwa komanso zovuta.
Makina otchulidwira zinthu zopindidwa mopanda phokoso nthawi zambiri amakhala kulimba kwamphamvu, kupanikizika kwapang'onopang'ono (kapena kupsinjika kwa umboni), elongation ndi Brinell kapena Rockwell kulimba.Zofunikira pazanyumba za bar, chubu, chitoliro ndi zokokera nthawi zambiri zimatsimikizira kulimba kwamphamvu ndikuchepetsa kupsinjika.
2. Perekani Mphamvu Zachitsulo Zosapanga zitsulo
Mosiyana ndi zitsulo zofatsa, mphamvu ya zokolola za chitsulo chosapanga dzimbiri cha austenitic ndi gawo lochepa kwambiri la mphamvu zamakokedwe.Mphamvu zokolola zachitsulo pang'ono nthawi zambiri zimakhala 65-70% ya mphamvu zamakokedwe.Chiwerengerochi chimakonda kukhala 40-45% mu banja la austenitic chosapanga dzimbiri.
Kuzizira kumagwira ntchito mwachangu komanso kumawonjezera mphamvu zokolola.Mitundu ina ya chitsulo chosapanga dzimbiri, monga waya wotenthedwa wa masika, imatha kugwira ntchito yozizira kuti ikweze mphamvu zokolola mpaka 80-95% ya mphamvu yolimba.
3. Kudumpha kwa zitsulo zosapanga dzimbiri
Kuphatikizika kwa kuchuluka kwa ntchito zowumitsa ntchito komanso kutalika kwakukulu / ductility kumapangitsa chitsulo chosapanga dzimbiri kukhala chosavuta kupanga.Ndi kuphatikiza kwazinthu izi, zitsulo zosapanga dzimbiri zimatha kupunduka kwambiri pamachitidwe ngati kujambula kozama.
Ductility nthawi zambiri imayesedwa ngati kutalika kwa% musanayambe kusweka panthawi yoyeserera.Zitsulo zosapanga dzimbiri za austenitic zimakhala ndi kutalika kwapadera.Ziwerengero zofananira ndi 60-70%.
4. Kuuma kwa chitsulo chosapanga dzimbiri
Kuuma ndi kukana kulowa kwa zinthu pamwamba.Oyesa kuuma amayezera kuzama komwe cholowera cholimba kwambiri chitha kukankhidwira pamwamba pa chinthu.Makina a Brinell, Rockwell ndi Vickers amagwiritsidwa ntchito.Iliyonse mwa izi ili ndi cholozera chowoneka chosiyana ndi njira yogwiritsira ntchito mphamvu yodziwika.Kutembenuka pakati pa masikelo osiyanasiyana ndikongoyerekeza.
Martensitic ndi mvula imawumitsa magiredi amatha kuumitsidwa ndi chithandizo cha kutentha.Magiredi ena akhoza kuumitsidwa ndi ntchito yozizira.
5. Kulimba Kwambiri kwachitsulo chosapanga dzimbiri
Kulimba kwamphamvu nthawi zambiri ndi chinthu chokhacho chamakina chomwe chimafunikira kufotokozera zinthu za bar ndi waya.Magiredi azinthu zofananira atha kugwiritsidwa ntchito pamphamvu zosiyanasiyana zolimbikira pazinthu zosiyanasiyana.Kulimba kwamphamvu komwe kumaperekedwa kwa ma bar ndi mawaya kumakhudzana mwachindunji ndi kugwiritsidwa ntchito komaliza pambuyo popanga.
Waya wamasika amakhala ndi mphamvu zolimba kwambiri pambuyo popanga.Mphamvu yayikulu imaperekedwa ndi kuzizira kogwira ntchito mu akasupe ophimbidwa.Popanda mphamvu iyi, waya sakanagwira ntchito bwino ngati kasupe.
Kulimba kolimba koteroko sikufunikira kuti waya agwiritsidwe ntchito popanga kapena kuluka.Waya kapena kapamwamba kogwiritsidwa ntchito ngati zomangira, monga mabawuti ndi zomangira, ziyenera kukhala zofewa kuti mutu ndi ulusi zipangidwe koma zolimba kuti zigwire ntchito mokwanira.
Mabanja osiyanasiyana a zitsulo zosapanga dzimbiri amakhala ndi mphamvu zosiyana siyana komanso zokolola.Mphamvu zofananira za zinthu zomwe zasungidwa zafotokozedwa mu Gulu 1.
Table 1. Mphamvu yeniyeni ya chitsulo chosapanga dzimbiri chochokera ku mabanja osiyanasiyana
| Kulimba kwamakokedwe | Zokolola Mphamvu | |
| Austenitic | 600 | 250 |
| Duplex | 700 | 450 |
| Ferritic | 500 | 280 |
| Martensitic | 650 | 350 |
| Kuuma kwa Mvula | 1100 | 1000 |
6. Thupi la Thupi la Stainless Steel
● Kukana dzimbiri
● Kutentha kwakukulu ndi kutsika kwa kutentha
● Kupanga zinthu mosavuta
● Mphamvu Zapamwamba
● Kukongola kokongola
● Ukhondo ndi kuyeretsa mosavuta
● Moyo wautali
● Zogwiritsidwanso ntchito
● Kuchepa kwa maginito
7. Kukaniza kwa chitsulo chosapanga dzimbiri
Kukana bwino kwa dzimbiri ndi gawo lazitsulo zonse zosapanga dzimbiri.Makalasi otsika a alloy amatha kukana dzimbiri mumikhalidwe yabwinobwino.Ma alloys apamwamba amakana dzimbiri ndi ma acid ambiri, njira za alkaline komanso malo okhala ndi chloride.
Kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri ndi chifukwa cha chromium yake.Nthawi zambiri, chitsulo chosapanga dzimbiri chimakhala ndi pafupifupi 10.5% chromium.Chromium yomwe ili mu aloyi imapanga gawo lodzitchinjiriza lodzitchinjiriza lomwe limadzipanga zokha mumlengalenga.Kudzichiritsa nokha kwa wosanjikiza wa oxide kumatanthauza kuti kukana kwa dzimbiri kumakhalabe kolimba mosasamala kanthu za njira zopangira.Ngakhale zinthu zitadulidwa kapena kuwonongeka, zimadzichiritsa zokha ndipo kukana kwa dzimbiri kumasungidwa.
8. Kutentha Kwambiri Kukaniza
Magiredi ena achitsulo chosapanga dzimbiri amatha kukana makulitsidwe ndikukhalabe ndi mphamvu kwambiri pakatentha kwambiri.Makalasi ena amakhalabe ndi makina apamwamba pa kutentha kwa cryogenic.
Kulimba Kwambiri kwa Chitsulo chosapanga dzimbiri
Mapangidwe a zigawo ndi njira zopangira zikhoza kusinthidwa kuti agwiritse ntchito ntchito yowumitsa zitsulo zosapanga dzimbiri zomwe zimachitika pamene akuzizira.Zotsatira zake zamphamvu zapamwamba zimatha kulola kugwiritsa ntchito zinthu zoonda kwambiri, zomwe zimapangitsa kuti pakhale zolemera komanso zotsika mtengo.
Gulu la Jindalai Steel Group ndi Wopanga & Wotumiza kunja wachitsulo chosapanga dzimbiri coil/sheet/plate/strip/pipe.Tili ndi zaka zopitilira 20 zachitukuko m'misika yapadziko lonse lapansi ndipo pano tili ndi mafakitale awiri omwe amapanga matani opitilira 400,000 pachaka.Ngati mukufuna kudziwa zambiri zazitsulo zosapanga dzimbiri, talandilani kuti mutitumizire lero kapena funsani mtengo.
