Kuwonongeka ndi Chitetezo cha Channel Steel

Chitsulo chachitsulo ndichitsulo chachitali chokhala ndi gawo lozungulira, la carbon structural steel pomanga ndi makina. Ndi gawo lovuta chitsulo chokhala ndi groove yooneka ngati mtanda. Chitsulo chachitsulo chimagwiritsidwa ntchito makamaka pomanga nyumba, kupanga magalimoto, ndi mafakitale ena, ndipo nthawi zambiri amagwiritsidwa ntchito pamodzi ndi matabwa a I. Chifukwa cha mawonekedwe ake apadera a metallographic ndi filimu yodutsa pamwamba, chitsulo chachitsulo nthawi zambiri chimakhala chovuta kuti chigwirizane ndi mankhwala ndi sing'angayo ndikukhala ndi dzimbiri, koma sichingawonongeke muzochitika zilizonse. Pogwiritsa ntchito chitsulo chachitsulo, mavuto osiyanasiyana amatha kukumana nawo, ndipo dzimbiri ndi imodzi mwazinthu zofunika kwambiri. Kuwonongeka kwachitsulo chachitsulo nthawi zambiri kumachitika chifukwa cha zifukwa ziwiri zotsatirazi.

1. Chemical dzimbiri: Madontho amafuta, fumbi, zidulo, alkalis, mchere, ndi zina zotere zomwe zimayikidwa pamwamba pa chitsulo chachitsulo zimasandulika kukhala zowononga pamikhalidwe ina, ndipo zimachitapo kanthu ndi zigawo zina muzitsulo zachitsulo, zomwe zimapangitsa kuti pakhale dzimbiri ndi mankhwala. dzimbiri; Zolemba zosiyanasiyana zimatha kuwononga filimu yodutsa, kuchepetsa mphamvu yoteteza chitsulo chachitsulo, ndikuchitapo kanthu mosavuta ndi ma media media, zomwe zimapangitsa kuti pakhale dzimbiri komanso dzimbiri.

2. Electrochemical corrosion: Zolemba zomwe zimachitika chifukwa chokhudzana ndi zitsulo za carbon ndi kupanga batire yoyamba yokhala ndi zida zowononga, zomwe zimapangitsa kuti electrochemical corrosion; Kuphatikizika kwa zinthu zomwe zimakhala ndi dzimbiri monga kudula kwa slag ndi kuwaza ku sing'anga yowononga kumapanga batire yoyamba, zomwe zimapangitsa kuti electrochemical corrosion; Zowonongeka zakuthupi (ma undercuts, pores, ming'alu, kusowa kwa kusakanikirana, kusowa kwa malowedwe, ndi zina zotero) ndi zolakwika za mankhwala (mbewu zowawa, tsankho, ndi zina zotero) m'dera lakuwotcherera zimapanga batri yoyamba ndi sing'anga yowonongeka, zomwe zimapangitsa kuti electrochemical corrosion iwonongeke. .

Choncho, njira zonse zogwira mtima ziyenera kuchitidwa panthawi yokonza zitsulo zachitsulo kuti zipewe kuchitika kwa dzimbiri ndi zokopa momwe zingathere. Njira imodzi ndiyo kugwiritsa ntchito zokutira zopopera za aluminiyamu. Kupopera mbewu za aluminiyamu zokutira ndi kusindikiza ndi zokutira zotsutsana ndi dzimbiri kumatha kutalikitsa moyo wautumiki wa zokutira. Kuchokera pazowunikira komanso zothandiza zogwiritsira ntchito, zokutira zopopera zinki kapena aluminiyamu ndizoyenera pansi pa zokutira zotsutsana ndi dzimbiri; Chophimba cha aluminiyamu chopopera chimakhala ndi mphamvu yolumikizana kwambiri ndi gawo lapansi lachitsulo, moyo wautali wokutira, ndi ubwino wachuma wautali wautali; Njira yopangira zitsulo zotayidwa ndi aluminiyumu ndi yosinthika komanso yoyenera kutetezedwa kwanthawi yayitali yazinthu zazikulu komanso zovuta kuzisunga, ndipo zitha kugwiritsidwa ntchito pamalowo.

Njira ina ndi kugwiritsa ntchito kanasonkhezereka odana ndi dzimbiri chitetezo: otentha-kuviika kanasonkhezereka njira zitsulo akhoza kugawidwa mu otentha-kuviika kanasonkhezereka njira zitsulo ndi otentha-wowombetsa kanasonkhezereka njira zitsulo malinga ndi njira galvanizing osiyana. Pambuyo pochotsa dzimbiri, zigawo zachitsulo zimamizidwa muzitsulo zosungunula za zinc kuzungulira 440-460 ℃ kuti zigwirizane ndi zinc wosanjikiza pamwamba pa zigawo zachitsulo, potero kukwaniritsa cholinga chotsutsa-kudzimbirira. M'mlengalenga, gawo lochepa thupi la zinc oxide limapangidwa pamwamba pa nthaka yosanjikiza, yomwe imakhala yovuta kusungunuka m'madzi motero imagwira ntchito yoteteza pazitsulo zachitsulo.

Shandong Kungang Chitsulo Technology Co., Ltd. imakhazikika mu zitsulo chitoliro ndi mankhwala mbiri, ndi maukonde malonda kuphimba zigawo angapo China ndi mayiko angapo kunja. Kupyolera mu khama la ogwira ntchito onse ndi mgwirizano waubwenzi wa mayunitsi a alongo, m'munda wosasinthasintha wa msika wogulitsa zitsulo, tingathe kumvetsa molondola chidziwitso ndi mwayi, kupitiriza kudziunjikira ndi kusintha pa liwiro lachangu, ndipo tapeza chitukuko ndi kukula kosalekeza. Ndi ntchito zabwino kwambiri komanso zinthu zapamwamba kwambiri, tapambana chidaliro cha makasitomala athu.
