Kufotokozera kwaifupi:
440c wopanda kapangidwe ka datikiri ndi chitsulo chosapanga dzimbiri chomwe chimadziwika chifukwa cha kuuma kwake kwakukulu, kuvala kukana, ndi kukana.
Zitsulo zosapanga dzimbiri 440c:
440c osapanga dzimbiri imatha kuwumitsidwa kuti ikwaniritse zovuta zapamwamba, makamaka pafupifupi 58-60 hrc (browwerder scale). , ndipo kukana kwamtundu wina. Amaperekanso kukana bwino mu malo ofatsa. Ndiwosagwirizana kwambiri kuposa matebulo ena okwera kwambiri chifukwa cha chromium zomwe zili .440c zopanga zosapanga dzimbiri zimatha kuchitidwa kutentha kuti mukwaniritse zojambula zamakina.

Mawonekedwe & Ubwino:
•Pambuyo pakutentha koyenera, chitsulo chosapanga dzimbiri chimatha kukhala zovuta kwambiri, makamaka pakati pa 58-60 hrc, ndikupanga kukhala koyenera kugwiritsa ntchito ntchito zofunika kwambiri.
•Chifukwa cha zokhudzana ndi mpweya wake wa kaboni ndi katundu wabwino kwambiri kutentha, 440c chitsulo chosapanga dzimbiri chimawonetsa kuti ndi ovala bwino, ndikupangitsa kukhala koyenera kugwiritsa ntchito zida zosiyanasiyana monga zida zodulira monga zida, etc.
•Ngakhale sikuti monga kutukuka ngati zitsulo zosapanga dzimbiri (mwachitsanzo, 304, 312, 312, 315), chitsulo cha 440C chosapanga dzimbiri chimakhalabe chifukwa cha chromium zomwe zili pamalo osungira osungira ng'ombe.
•440c osapanga dzimbiri imatha kukhala bwino pansi pa malo oyenera kuti mukwaniritse zofunika zosiyanasiyana. Komabe, chifukwa cha kuuma kwake komanso mphamvu zake, makina amatha kukhala ovuta komanso amafunika njira zopangira makina oyenerera.
•440c chitsulo chosapanga dzimbiri chikuwonetsa kusakhazikika kwamanja kwambiri, kumapangitsa kuuma kwake ndikumavala kukana kutentha kutentha, kumapangitsa kukhala koyenera kugwiritsidwa ntchito m'malo otentha kwambiri.
•Makina omwe amagwiritsa ntchito 440c osapanga dzimbiri amatha kusintha pogwiritsa ntchito kutentha, monga kuuma, mphamvu, komanso kulimba, kuti mukwaniritse zofunika pa ntchito.
Chifukwa chiyani tisankhe?
•Mutha kupeza zinthu zabwino malinga ndi zomwe mukufuna pamtengo wochepera.
•Timaperekanso obwezeretsanso, fob, CFR, COB, ndi khomo ndi mitengo ya khomo. Tikukulimbikitsani kuti muchite zotumizira zomwe zingakhale zachuma.
•Zipangizo zomwe timapereka ndizotsimikizika kwathunthu, kuchokera ku satifiketi ya sifiketi yomaliza yomaliza. (Malipoti adzawonetsa zofunikira)
•Tikutsimikizira kuyankha mkati mwa 24hours (nthawi zambiri nthawi yomweyo)
•Perekani lipoti la SGS.
•Timadzipereka kwambiri kwa makasitomala athu. Ngati sizingatheke kukwaniritsa zofunikira zanu mutapenda zosankha zonse, sitikusocheretsani popanga malonjezo abodza omwe angapangitse ubale wabwino womwe ungapangitse ubale wabwino.
•Perekani ntchito imodzi.
Kodi 440c osapanga dzimbiri ndi chiyani?
440c osapanga dzimbiri imapereka ndalama zambiri kukana ndikutsutsana mosiyanasiyana mu malo ofatsa, okhala ndi mabedwe abwino. Imagawana kufanana ndi kalasi ya 440b koma ili ndi zinthu zapamwamba pang'ono za kaboni pang'ono, zomwe zimapangitsa kulimba kwambiri koma kuchepetsedwa pang'ono kukana kuwonongeka poyerekeza ndi 440b. Itha kukwanitsa kulimba kwa 60 strickhr hrc ndikukamiza malo okhala ndi mafakitale ofananira komanso ofatsa, omwe akukana kutsutsana kwathunthu 400 ° C Platening kutentha. Kukonzekereratu ndikofunikira kwambiri kukana bwino kwambiri, kuyenera kuchotsedwa kwa kuchuluka, mafuta, tinthu tating'onoting'ono, ndi zokutira. Zomwe zimachitika kwambiri ma carbon zimalola kugwiritsa ntchito makina ofanana ndi zitsulo zothamanga kwambiri.
440c osapanga dzimbiri zosapanga
440c osapanga dzimbiri zozungulira zimagwiritsidwa ntchito kwambiri pakupanga mpeni, zonyamula, zida zodulira, zida zamagetsi, ndipo zidali zolimba, zimapangitsa zisankho zabwino kwambiri magwiridwe antchito komanso kukhazikika kwa nthawi yayitali.
Kuwala kwa chitsulo chosapanga dzimbiri 440C:
Chifukwa cha kuuma kwake kwakukulu komanso kumasuka kwa mpweya wowuma, kuwotcherera ndi chitsulo cha 440C chosapanga dzimbiri ndichabe. Komabe, ngati kuthyolako kumakhala kofunikira, tikulimbikitsidwa kuti mupatse zomwe 260 ° C (500 ° F) ndikuchita Chithandizo-Inch Custick Chithandizo cha 732-740 ° F) Kwa maola 6, kenako Chotsani ntchentche yozizira kuti muchepetse kusweka. Kuonetsetsa zofananira zofananira pazithunzi ngati chitsulo chachitsulo, kuwotcherera zosemphana ndi zomwe zimachitika zomwe zikuyenera kugwiritsidwa ntchito. Mwinanso, ASS E / ER309 Ikhozanso kuonedwa ngati njira yoyenera.
Makasitomala athu
Mayankho ochokera kwa makasitomala athu
400 Zingwe zopanda banga zimakhala ndi zabwino zingapo, zomwe zimapangitsa kuti athandizidwe ndi magwiridwe osiyanasiyana. Zingwe zitsulo nthawi zambiri zimakhala zaulere - zowonetsera zowonetsera bwino kwambiri. Izi zimawapangitsa kukhala kosavuta kudula, mawonekedwe, ndi kukonza mapangidwe achitsulo osapanga mapangidwe okhazikika mogwirizana ndi nyonga ndi kuuma, oyenerera ntchito yofunika kwambiri komanso yopanga zigawo zamakina.
Kulongedza:
1. Kulongedza ndi kofunikira kwambiri makamaka pamayendedwe apadziko lonse lapansi omwe amapereka njira zosiyanasiyana kuti afike komwe akupita, motero timayika nkhawa zapadera pofotokoza.
2. Timanyamula zogulitsa zathu m'njira zingapo, monga,
