I te 20 o Tīhema, i rongo te kairīpoata mai i te Kamupene Rangahau Rino me te Maitai o Haina, a Gaona, ko te kamupene te kaiārahi i te mahi tahi i te hanga i a Fushun Special Steel me Erzhong Wanhang mō te wā tuatahi i ngā rā tata nei, kia angitu ai te whakamātautau i te hanga kōpae whakauru tāwhana nui rawa atu i tōku whenua i tēnei wā—— Ko ngā hanga kōpae tāwhana nui rawa atu a GH4706, e tika ana mō te whakamahi i raro i ngā āhuatanga pāmahana teitei o te 650 nekehanga Celsius, me te taumata kaha o te 1200 MPa, te taumaha o te 13.5 tana, me te diameter o te 2380 mm, i pakaru te mana pupuri a tāwāhi.
E ai ki a Zhao Guangpu, te kaiārahi o te kaupapa rangahau me te kaiwhakahaere tuarua o te Komiti Pūtaiao me te Hangarau Rangahau Rino a Gona, he tino pai ngā painga o ngā tāwhana hau taumaha mō ngā teihana hiko nui pērā i te kaha teitei, te pai o te wera, te iti o te rahinga me te taumaha, me te iti o te parahanga. Kua noho tōna hangarau hanga hei taumata hangarau ā-motu. , Ko tētahi o ngā tohu nui o te kaha whānui o te motu. Ko ōna wāhanga matua o te pito wera he kōpae kotahi me te rua (ngā kōpae me ngā aratohu tāwhana, ngā mata mahi), e mahi ana hei "ngākau" o te tangata. Koinei te hangarau matua mō te hanga tāwhana hau me te aukati e aukati ana i te rohe o ngā tāwhana hau taumaha. Neke atu i te 100,000 hāora o te ratonga pāmahana teitei me te ahotea teitei mō ngā kōpae tāwhana hau taumaha, ā, me tino kounga teitei o ngā rauemi whakarewa, pērā i te hanganga rauemi ōrite, parakore, pai te hanganga, te pumau; he nui ake te rahi, ā, ko tōna whānui me te horahanga whakaata he nui ake. Neke atu i te 2.2 mita te whānui me te 4.2 mita pūrua, arā, e 4 ngā wā o te whānui o te kōpae tāpine miihini aero, e 10 ngā wā o te horahanga whakaata, ā, e 60 ngā wā o te taumaha, me ērā atu. Ko te hangarau hanga matua o ngā kōpae tāpine super-alloy rahi rawa kua tino āraia ki tāwāhi, ā, kua roa e puritia ana e ngā whenua o te Hauāuru.
Hei whakatutuki i tēnei kaupapa, i ārahi a Zhao Guangpu i te tīma kaupapa ki te whakahaere i tētahi raupapa rangahau taketake me te rangahau hangarau, ā, i te mutunga ka whakamahia te hangarau whakarite "whakarewa toru + whakatikatika anō + whakatikatika rua + hanga mate kotahi-ahi" o te ao matatau rawa atu hei whakatinana i ngā Paerewa o te ao, me te wawahi i te arai hangarau o te whakarite kōpae turbine superalloy nui i tūtakihia i te wā o te tukanga whakawhanake, pērā i te hangarau whakarewa wehewehe-iti toru mō ngā poro maitai nui me ngā poro neke atu i te 18 tana te taumaha, me te hangarau whakatikatika anō me te pua pai mō ngā pae nui me te diameter o te 1000 mm, me te diameter o te 2200. Hangarau hanga mate whakauru me te hanga pāmahana iti me te whakahaere mō ngā wāhanga pereti nui nui atu i te mirimita. I whakahaerehia e te tīma kaupapa te rangahau me te whanaketanga motuhake me te auahatanga taketake mō ngā hapa whakarewa pērā i te ihirangi Nb tino tiketike o te huānga whakarewa i roto i te superalloy GH4706, he ngāwari ki te wehewehe i ngā ira pango me te ira mā. Ko ngā wāhanga matua o ngā tāpine hau taumaha o tōku whenua ko te "kaki piri", ā, kua huaki tēnei i tētahi ara tukanga mō te whakarite i ngā kōpae tāpine superalloy kua whakarerekētia te āhua me ngā āhuatanga Hainamana me ngā mana pupuri hinengaro motuhake.
Whai muri i te hanganga tinana, kua eke te mahi a te kōpae tāpine ki ngā whakaritenga hangarau o ngā koranu rite o tāwāhi, ā, kua tutuki he hua nui. Ko tētahi atu putanga nui tēnei kua tutuki i tōku whenua i roto i te mara o ngā koranu tino rerekē, kua akiaki i te hangarau whakarite o ngā kōpae tāpine nui rawa atu o te motu kia eke ki te taumata rangatira o te ao. I te 8 o Tīhema, i tū te hui arotake pūnga nui mō ngā whakarewa roulette rahi-katoa o te koranu GH4706 i Beijing. I tino arotakehia e ngā tohunga, ko te tikanga kua tangohia he taahiraa pakari ki te whakamahinga tūturu o te kōpae tāpine.
