Tikanga tineia o Steel Pipe Deformation me te Kapiti

Austempering ko ki te whakaiti i te deformation o te putorino maitai me te tikanga whai hua o te tinei kapiti Jian, engari me pehea ki te tika te whakamahi i te tikanga tukanga kia hāngai i runga i te tika rauemi putorino maitai, te rahi, pakeke me te uaua, whakaritenga deformation, me ngā tikanga mahi motuhake te. Ko te whiriwhiri ko nga raru tiini Isotherml e tika ana kia arohia ka whakarapopotohia penei:
[1] Pērā i te waro maitai me etahi atu iti o te whakapakeke o te maitai austempering tinei whakapakeke, kia tika ki te whakanui ake i te pāmahana tineia, H he ki te whakapiki ake i te pūmautanga o te austenite ki te karo me te aukati i te takanga o te teitei-te pāmahana-kore mataitai i roto i te te whakapouri i te tinana o te huringa tinei.

[2] Austempering whakatiki maitai me te rahi paipa. I roto i te tinei austempering tinei, te parau tumu taketake ko ki te whakarite kia kore e puta huringa parakore maitai teitei pāmahana i roto i te tukanga meangiti, a reira te rahi o te paipa paipa maitai kōeke maitai me te pānga tika i runga i te kounga o te tinei austempering tinei, te whānui whakaritenga mo te waro maitai putorino tui te matotoru whai hua kia iti iho i te 5mm, kia iti iho i te 30mm te matotoru whai hua o te koranu. Mai i te tirohanga o te ihirangi waro i roto i te 0.4% ki te 0.6% o te waro kaore i te pai mo te austempering, teitei ake i te 0.6% neke atu ranei o te waro maitai ki te austempering tinei.

[3] Ko te pāmahana me te wa kia noho i runga i te whakamaarama i nga whakaritenga mahi paipa paipa paipa, e tohu ana ki te peera C-piri kua whakatauhia, i roto i te kaupapa, ka huri katoa te austenite ki te bainite, i runga i te reo whakamahana te nuinga o te wairewa pati pākawa i roto i te raupapa. ki te whakarite i te pāmahana pūmau, me whakauru te taputapu whakamahana ki roto i te reo kia kore ai te piki o te pāmahana o te reo ka pa ki te kounga o te tinei. Etc. I tua atu i te roanga o te wa me whakarite te pāmahana i te mutunga whakawhiti paipa maitai tui hei tohu tohu, ka heke te pai o te mahi roa, na reira me ata whakaaro.

[4] Austempering hardening steel and some not be tempered. Engari mo etahi ^ ka whakapakeke te tinana o te mea mahi, ka huri te toenga o roto o te austenite i roto i te mahi whakamahana hau i muri mai he martensite, me whakamaarama, ko te kaupapa ko te whakakore i te pakaruhanga me te pumau o te rangatira rino korekore, kia mahara ko te whakamahana o te werawera kia rite. i raro iho i te pāmahana austempering.
