Ngā Pātai Auau (FAQ) – Ngā ihirangi hou katoa

Q: He aha i hiahiatia ai kia kotahi te whakarewanga o ngā kohua para nui, kaua e whakarewaina?
A: Ka pāngia ngā hononga whakarewa i roto i ngā kohua nui e ngā rerekētanga taumahatanga wera nui (1,600°C i roto ki waho). Ka puta he kapiti ngenge i ngā matimati whakarewa nā te kore e ōrite te whānui o te wera i roto i te 2,000 huringa noa iho. Ka tangohia e te whakarewa whakauru ngā rārangi whakarewa katoa, ka tohatohahia te taumahatanga kia ōrite puta noa i te konganuku ōrite.

P: Me pēhea te whakamātautau i tētahi kohua para 100-tana mō ngā hapa huna?
A: Ka whakakotahi mātou i te whakamātautau ultrasonic aunoa (AU) me te huinga ā-wāhanga hei matawai i te 100% o te rōrahi, me te whakaahua wera i te wā e tukatukahia ana, me te tirotiro matūriki aukume i runga i ngā mata katoa. Ka pāngia ngā rohe trunnion e te diffraction wā-o-te-rere (TOFD) hei kimi i ngā kapiti.

Q: Ka taea e tātou te whakamahi i te kohua para kotahi mō te ratonga BOF me te EAF?
A: Kāore i te tūtohutia. He wai ake te para BOF engari he kaha ake te matū; he matotoru ake te para EAF, ā, kei roto ngā mea whakarewa. Ka hoahoa mātou i ngā koki pakitara me ngā arai o te kohua mō te tukanga kotahi. He maha ngā wā ka ngoikore te mahi a ngā kohua mahi-rua.

Q: He aha te wā tuku noa mō te kohua para 70-tana?
A: 22–26 wiki mai i te whakaaetanga tuhi whakamutunga. Kei roto i tēnei ko te hanga tauira (4 wiki), te whakarewa me te whakamahana (6 wiki), te NDT (2 wiki), me te miihini/paninga (2 wiki). Ka taea te tono tere me te tauira kua oti kē te hanga.

Q: E hia ngā huringa ka taea e au te tumanako i mua i te whakatikatika tuatahi?
A: I runga i ā mātou raraunga mai i ngā mira whakauru e 38, ko ngā huringa waenga i mua i te pakaru o te mata ka kitea8,200 huringaMā te huri iti ka roa ake te ora o te mīhini ki te 12,000 huringa. E taunakihia ana kia whakamanahia anō ia 10 tau, ia 15,000 huringa rānei.

Q: Ka taea e koe te whakarato i ngā kohua para me te kimi para aunoa, te aroturuki pāmahana rānei?
Āe. Ka taea e mātou te whakauru i ngā takirua wera ki te raro o te kohua (me ngā pute tiaki) me te tāuta i tētahi papa whakairi mō ngā pūoko taumata para radar. Kua makahia ngā awa waea ki roto hei karo i ngā whāriki o waho.

Q: He aha te whānui o waho mōrahi ka taea e koe te maka?
A: Ka taea e tā mātou whare hanga whakarewa te whakamahi i ngā diameter o te tihi o te kohua tae atu ki te 3.6 mita (142 inihi). Ka taea te hanga kohua nui ake mā te whakamahi i te whakarewatanga wāhanga me te whakarewa, engari ka tino taunaki mātou i te whakarewatanga whakauru mō te mahi pai rawa atu.

Q: Kei te tuku pūtāhui roa koe mō ngā kohua para nui?
A: Kei a mātou he pūtāhui 18-marama / 5,000-huringa – ko tēhea te mea tuatahi. He rua tēnei o te paerewa ahumahi. Ka taea te whiriwhiri i te pūtāhui e hangai ana ki te mahi mō ngā ota anō.

P: Me pēhea te manatoko i te kaha o te trunnion i muri i ētahi huringa?
A: Ka tūtohu mātou kia whakamahia he UT kawe i roto i te wāhi i ia 12 marama. Ka taea e Womic te whakarato i tētahi kete tirotiro mara me te whakangungu. Mena ka kitea he nui rawa te pakaru, ka taea te whakakikorua i ngā poroporo ki te konganuku whakarewa me te whakahou i te mīhini.

Q: Ka taea e koe te hoahoa i tētahi kohua para kia uru ki ā mātou matau kerēni o nāianei me te kore e whakarerekē i te kerēni?
Āe. Me tuhi te kōtaha matau o te kerēne (tae atu ki te whānui o te whakatuwheratanga o te matau, te hohonu o te korokoro, me te radius o te āputa). Ka whakatauritea e mātou te āhua o te porowhita ki ō taputapu hiki o nāianei.
