Kutentha mankhwala ndondomeko ya seamless zitsulo chubu

Sindikudziwa momwe mukudziwira Chitoliro chachitsulo chosasinthika? Machubu achitsulo osasunthika ndi ozungulira, makwerero komanso amakona anayi opanda machubu achitsulo opanda zolumikizira zakunja. Chubu chachitsulo chosasunthika chimapangidwa ndi ingot yachitsulo kapena cholimba chubu billet kudzera perforation mu capillary chubu. imapangidwa ndi kugudubuza kotentha, kugudubuza kozizira kapena kujambula kozizira. Machubu achitsulo opanda msoko amakhala ndi zibowo ndipo nthawi zambiri amagwiritsidwa ntchito ngati ngalande zonyamulira madzi. amafunikira kupindika kofanana ndi mphamvu yopindika ndipo ndi yopepuka kuposa chitsulo cholimba ngati chitsulo chozungulira. Ndiwo zitsulo zotsika mtengo ndipo zimagwiritsidwa ntchito kwambiri popanga zomangira, magawo ndi zida zamakina, monga zitsulo zopangira zitsulo zomwe zimagwiritsidwa ntchito pobowola mafuta.
Mu njira zopanda zitsulo zachitsulo, pali njira zambiri zopezera mapaipi okhala ndi khalidwe labwino kwambiri. Kapangidwe kokwanira kachitsulo kamene kamapezeka pochotsa kuuma kwa machubu opanda zitsulo. Njira zida ndi yowala annealing ng'anjo, makamaka ntchito. Chitsulo cha chrome chomalizidwa chimatenthedwa mumlengalenga woteteza kwambiri. Pamene magwiridwe antchito a chitoliro chachitsulo chosasunthika ndi chosiyana, mawonekedwe a metallographic pambuyo pa annealing owala amakhala osiyana, chifukwa chake njira yopangira kutentha kowala idzakhala yosiyana.
Pambuyo pogwira ntchito mozizira, kupsinjika kotsalira kwa chitoliro chopanda chitsulo chosasunthika kumakhalabe, chifukwa chake kupsinjika kotsalirako kumakhala koyipa kwambiri pakuwonongeka kwa chitoliro cha chitoliro. Kugwira ntchito kulikonse kozizira kumabweretsa kuwonjezeka kwakukulu kwa kupsinjika kwa dzimbiri kusweka. Kuchuluka kwa kuzizira kumagwiranso ntchito kumakhudzanso kukana kutentha kwa austenitic chitsulo chosapanga dzimbiri. Nthawi zambiri, kumtunda kwa kutentha kwa ntchito kapena kumtunda kwa zofunikira za moyo wosweka, kumachepetsa kuzizira kozizira.
Monga tawonera pamwambapa, njira yothandizira kutentha kwa chitoliro chopanda chitsulo ndizovuta. kuti apeze oyenerera metallographic dongosolo, kusintha mbali ya zida kuzirala gawo ng'anjo yowala annealing ayenera kukhala lalikulu. Chifukwa chake, ng'anjo yowunikira yowala kwambiri nthawi zambiri imagwiritsa ntchito kuziziritsa kwamphamvu kwa convection mu gawo lake lozizirira, ndipo imakhala ndi magawo atatu ozizirira, omwe amatha kusintha kuchuluka kwa mpweya padera. imagawidwa m'magawo atatu m'lifupi mwake.
