E hiahia ana te umanga rererangi ki ngā rauemi e kaha ana ki te tu atu i ngā pāmahana tino kino, ngā pēhanga teitei, me ngā taiao waikura—me te pupuri tonu i te hanganga pai me te whakaiti i te taumaha. I roto i ngā konganuku e whakamahia ana i roto i ngā mahi rererangi me te wāhi,kowiri tirakei a ia tētahi tūranga nui nā te meate taurite ahurei o te kaha, te ātete ki te waikura, me te āheinga ki te hanga.
I roto i tēnei tuhinga, ka tūhuratia e mātou ngāngā āhuatanga me ngā painga o te kowiri tira i roto i te rererangi, ōna whakamahinga noa, me te take e whakawhirinaki tonu ai ngā kaihangarau ki tēnei mea mō ngā pūnaha haumaru-nui. I whakaaturia esasaalloy, tō puna pono mō ngā koranu maitai kore waikura mahi teitei i hangaia mō te hiranga o te rererangi.
He aha i whakamahia ai te maitai kore waikura i roto i te rererangi
Ko te maitai kore waikura he koranu i hangaia tuatahitia mai irino, chromium (iti rawa 10.5%), me ētahi atu huānga pērā inikara, moripenema, me te tiitaniumaMā tēnei hanganga ka taea e te rauemi te hanga i tētahipaparanga kore mahie tiaki ana i a ia mai i te waikura me te waikura, ahakoa i raro i ngā āhuatanga taiao kino.
Mō te rererangi, he huinga onge o ngā mea e whai ake nei te maitai kore waikura:
-
Te kaha kume teitei
-
Ātete ki te waikura me te wera
-
Te ātete ngenge me te ngokingoki
-
Te ngāwari o te mahi me te ngāwari o te whakarewa
-
Ātete ahi me te waikura
Nā ēnei āhuatanga i pai ai te maitai kore waikura mō ngā mahi rererangi hanganga me ngā mahi rererangi kore-hanganga.
Ngā Āhuatanga Matua o te Kowiri tira i roto i te Rererangi
1. Te Kaha me te Pūmau o te Mīhini
Ka pāngia ngā wāhanga rererangi e ngā huringa auau o te ahotea me te wiri. He teitei te kowiri tirate kaha hua me te ātete ngengekia pai ai mō ngā mahi amo kawenga pērā i te taputapu taunga, ngā wāhanga mīhini, me ngā whakapiri.
2. Ātete ki te Waikura
I ngā teitei me te wāhi, ka tūtaki ngā rauemi kite makuku, ngā wai tango hukapapa, te hau tote, me ngā matū kinoHe tino ātete te maitai kore waikura ki te waikura whānui me te waikura ā-rohe (ngā poka me ngā kapiti), e whakarite anate pono mō te wā roa.
3. Ātete Pāmahana-Teitei
Ka whakaputa ngā miihini rererangi me ngā tono hypersonicwera nuiNgā maitai kore waikura Austenitic, pērā i304, 316, me te 321, kia mau tonu te kaha me te ātete ki te waikura ahakoa i runga ake i te 600°C. Ko ngā momo kua whakapakeketia e te ua pērā i17-4PHhe tino pai tana mahi i raro i te wera me te ahotea.
4. Te Āhua me te Hanganga
He ngāwari te kowiri tirai mīhinihia, i whakarewahia, ā, i hangaia, e āhei ai ngā āhua uaua me ngā hoahoa ritenga. He mea nui tēnei i roto i te ao rererangi, me tutuki i ngā wāhanga ngā paerewa me ngā taunga kaha.
5. Ātete Ahi me te Ngoki
He rerekē ki te nuinga o ngā koranu mama, ka taea e te maitai kore waikura te ātete ki te whakarerekētanga (te ngokingoki) me te pupuri i te kaha.i raro i te wera roa, kia pai ai mō ngā wāhanga tino nui o te ahi.
