301 lamba wachitsulo chosapanga dzimbiri ndiye chinthu chofunikira kwambiri chogwiritsidwa ntchito.Chifukwa chachikulu kuuma kulolerana, ntchito munda ndi lalikulu kwambiri.Lamba wachitsulo chosapanga dzimbiri 301 amafanana ndi chizindikiro chatsopano cha China: 12Cr17Ni7 ndi chizindikiro chakale cha 1Cr17Ni7.
Chifukwa zomwe zili ndi kaboni ndizabwinoko kuposa 304, zimakhala ndi ntchito yabwino potengera kuuma kwakukulu.Kuuma kwapamwamba kumatha kufika pafupifupi madigiri a H620, omwe sapezeka ndi zida wamba.301 kuuma
Sikelo imatha kugawidwa mu madigiri a HV200 ~ HV620 madigiri, ndipo kuuma kwapansi pa madigiri 420 kumatha kugawidwa ndi zida za 304!Pankhani ya kukana, ndi yotsika kuposa 420HV, makamaka 304 zakuthupi, chifukwa
Lamba wachitsulo wosapanga dzimbiri wa 304 uli ndi mpweya wabwino kwambiri, wabwino kuposa zinthu 301 potengera kukana!

SUS301 (17Cr-7Ni) zitsulo zosapanga dzimbiri zimatha kupeza mphamvu zambiri pambuyo pozizira.301 chitsulo chosapanga dzimbiri ndi mtundu wazitsulo zosapanga dzimbiri za austenitic.Pansi pa chikhalidwe cha yankho lathunthu, zatero
ali ndi dongosolo la austenite.Pakati pazitsulo zosapanga dzimbiri, 301 ndi chitsulo chomwe chimalimbikitsidwa kwambiri ndi kuzizira kozizira.Mphamvu ndi kuuma kwa chitsulo kumatha kupitilizidwa ndi kuzizira kozizira, ndipo zofunikira zimasungidwa.
pulasitiki ndi kukana, kuphatikiza ndi chitsulo ichi ali ndi dzimbiri kukana kwambiri mumlengalenga, koma osauka dzimbiri kukana kuchepetsa TV, osauka dzimbiri kukana mu mankhwala TV monga asidi, alkali ndi mchere,
Choncho, izo si ovomerezeka kwa dzimbiri malo ankhanza.301 imagwiritsidwa ntchito makamaka m'malo ozizira kuti avomere katundu wambiri, komanso ikuyembekeza kuchepetsa kulemera kwa zida ndi zida zopanda dzimbiri.
Nthawi zambiri imakulungidwa bwino, yololera makulidwe a 0.01mm-0.005mm.Mzere wachitsulo chosapanga dzimbiri wa SUS301 Chifukwa cha kulimba kwake kwakukulu komanso kukhazikika bwino, akasupe akasupe onse amagwiritsidwa ntchito
301 lamba wachitsulo chosapanga dzimbiri.Magalimoto a njanji, zotengera lamba, mabawuti ndi mtedza, akasupe, ndi zina zambiri. Zopangira mawotchi otchipa, kugwiritsa ntchito lamba wachitsulo wapamwamba kwambiri, ndi zina zambiri.
Nkhani zopanga ndi njira zopangira zitsulo zosapanga dzimbiri
Mzere wachitsulo chosapanga dzimbiri ndi wosavuta kuchita dzimbiri m'madzi ndi mpweya.Kuchuluka kwa zinki mumlengalenga ndi 1/15 yokha ya chitsulo chomwe chimawonongeka mumlengalenga.Chitsulo chopangidwa ndi galvanized chimagwiritsidwa ntchito posungira mbale yachitsulo ndi wosanjikiza wandiweyani.Tetezani ku dzimbiri.Lamba wachitsulo chosapanga dzimbiri amatanthauza lamba wonyamulira wopangidwa ndi chitsulo cha kaboni ngati chokokera ndi membala wonyamula lamba.Itha kugwiritsidwanso ntchito kusonkhanitsa katundu.Ndikofunikira kwa mabizinesi osiyanasiyana ogubuduza zitsulo kuti azolowere kupanga mafakitale azinthu zosiyanasiyana zazitsulo kapena zamakina m'mafakitale osiyanasiyana.Ndipo mbale yopapatiza komanso yayitali yachitsulo idapangidwa.
Mzere wachitsulo chosapanga dzimbiri uli mkati mwa 1300mm, ndipo kutalika kwake kumakhala kosiyana pang'ono ndi kukula kwa mpukutu uliwonse.Chitsulo chaching'ono nthawi zambiri chimaperekedwa ndi ma coil, omwe ali ndi maubwino olondola kwambiri, mawonekedwe abwino, kukonza kosavuta, komanso kupulumutsa deta.Zingwe zachitsulo zimagawidwa kukhala zitsulo wamba ndi zitsulo zapamwamba kwambiri malinga ndi zida zomwe zimagwiritsidwa ntchito, ndipo chingwe chachitsulo chotentha ndi chitsulo chozizira chimayikidwa molingana ndi njira yopangira.
Mzere wachitsulo chosapanga dzimbiri uli ndi zotsatira zazikulu, zogwiritsidwa ntchito zosiyanasiyana, ndi mitundu yambiri yazitsulo.Amagawidwa muzitsulo zotentha zotentha ndi zitsulo zozizira motsatira njira yopangira;ogaŵikana woonda zitsulo Mzere (makhuthala zosakwana 4mm) ndi wandiweyani zitsulo Mzere (makhuthala aakulu kuposa 4mm) malinga makulidwe, ndipo anawagawa m'lifupi zitsulo Mzere malinga ndi m'lifupi (m'lifupi kuposa 600mm) ndi yopapatiza zitsulo n'kupanga (m'lifupi osati wamkulu kuposa 600mm) ), tizitsulo tating'onoting'ono tachitsulo timagawidwa kukhala tizitsulo tating'onoting'ono tachitsulo ndi tizitsulo tating'onoting'ono tachitsulo kuchokera kuzitsulo zazikulu.Malingana ndi maonekedwe awo, amagawidwa kukhala mawonekedwe oyambirira ogubuduza ndi plating (kuphimba) maonekedwe.Malamba achitsulo amagawidwa m'magulu onse komanso apadera (monga matumba, milatho, ng'oma zamafuta, mapaipi otsekemera, zolongedza, magalimoto odzipangira okha, etc.) malamba achitsulo malinga ndi ntchito zawo.
Kupanga zitsulo zosapanga dzimbiri ndizofunikira
1. Musanayambe makinawo, fufuzani ngati mbali zozungulira za zipangizo ndi magetsi ndi otetezeka komanso odalirika.Ngati pali vuto lililonse, pezani ogwira nawo ntchito kuti akonze panthawi yake.
2. Zomwe zili pa malo ogwirira ntchito ziyenera kusungidwa bwino, ndipo pasakhale zopinga pa ndimeyi.
3. Oyendetsa galimoto ayenera kuvala zovala zantchito, kumanga makafu ndi makona mwamphamvu, kuvala zipewa zogwirira ntchito, magolovesi, ndi magalasi otetezera.
4. Poyendetsa galimoto, sikuloledwa kuyeretsa, kuthira mafuta ndi kukonza zipangizo, kapena kuyeretsa malo ogwirira ntchito.Musakhudze lamba wachitsulo ndi mbali zozungulira ndi manja anu poyendetsa galimoto.
5. Ndizoletsedwa kuyika zinthu kapena zinthu zina pazida kapena chivundikiro chokonzekera pamene mukuyendetsa galimoto.
6. Mukamagwiritsa ntchito hoist yokweza magetsi, malamulo oyendetsera chitetezo amayenera kutsatiridwa, chingwe cha waya chiyenera kuyang'aniridwa ngati chili bwino ndipo mbedza iyenera kupachikidwa.Mukakweza lamba wachitsulo, sikuloledwa kutsetsereka kapena kupachika lamba wachitsulo mumlengalenga panthawi yopanga.
7. Pamene ntchitoyo yatha kapena mphamvu imadulidwa pakati, magetsi ayenera kutsekedwa mwamsanga.
