Ina kore e taea te hinga. Koinei te āhua o ngā mahi keri e neke ana i te 5,000+ tana o te rino i ia hāora puta noa i ngā kiromita o te whenua paripari. Koinei anō hoki te āhua o ngā tauranga e uta ana i ngā uta nui i ngā nekehanga 24/7, me ngā wheketere sima e whāngai ana i te clinker ki roto i ngā oumu e kore e whakamatao.

I ēnei taiao, ehara te whitiki kawe i te taonga hokohoko. Koia te pou tuarā o tō whakaputanga. Ā, ina tohua e ngā miihini he whitiki whakakapinga mō ēnei mahi, kāore rātou e rapu i te "whitiki kawe" — engari e rapu ana rātou i te whitiki kawe taura maitai me te whakatauranga ST motuhake.

Mena he kaiwhakahaere hokohoko koe, he miihini tiaki, he kaiwhakahaere tipu rānei e rapu ana i tētahi kaiwhakarato whitiki kawe taura maitai pono, kua tuhia tēnei aratohu māu.

He aha teWhitiki Kawe Taura Rino?

He whitiki rapa taumaha te whitiki kawe taura maitai, he mea whakapakari ki roto mā te whakamahi i ngā taura maitai roa (ngā taura) kaua ki ngā papa papanga. Ka whakaratohia e ngā taura maitai te kaha kume e hiahiatia ana mō:

• Te kawe tawhiti — ngā pūnaha rere kotahi neke atu i te 10 km
• Te kawe hiki-teitei — ngā hiki poutū o te 500 m, neke atu rānei, i te wāhanga kotahi
• Ngā mahi taumaha-tāne — te nui o te putanga neke atu i te 5,000 tana/h

He rerekē ki ngā whitiki papanga e totoro ana i raro i te kawenga pumau, he iti noa te roa o ngā whitiki taura maitai (he iti iho i te 0.25%), arā, he iti ake te haere o te tango, he iti ake te auau o te honohono anō, ā, he roa ake ngā wā mahi.

Te Mārama ki ngā Whakatauranga ST: Ngā Kaihanga Reo e Kōrero Ana

Ina kite koe i a ST630, ST1000, ST1600, ST5400 rānei, kei te titiro koe ki te whakatauranga kaha kume o te whitiki i roto i te N/mm (Newtons ia mirimita o te whānui o te whitiki). Ko te teitei ake o te tau, ko te kaha ake o te whitiki.

Whakatauranga ST	Kaha Kume	Te Whakamahinga Noa
ST630 – ST1000	630–1,000 N/mm	Te keri mahi-waenga, ngā keri tāpua, ngā kaikawe i ngā pāmu kararehe
ST1250 – ST1600	1,250–1,600 N/mm	Ngā maina waro, ngā wheketere sima, ngā mīhini tāpae/whakahoki tauranga
ST2000 – ST2500	2,000–2,500 N/mm	Ngā kaikawe roa o uta, te kawe rino kaha-nui
ST3150 – ST4000	3,150–4,000 N/mm	Te hiki hohonu i te toki, ngā pūnaha hiki tino-rahi, te tukunga pakaru tuatahi
ST4500 – ST5400	4,500–5,400 N/mm	Ngā tono taumaha rawa atu — ngā kauhanga whānui, ngā kawe pūngao nui-maina

Tohutohu ngaio mai i ā mātou miihini: He maha ngā kaihoko e tino whakatau ana i te whakatauranga ST "hei haumaru noa iho," ka piki ake te utu o te whitiki, ngā whakaritenga diameter o te pūrei, me te uaua o te hononga. Ko te whakatauranga ST tika ko te mea e tutuki ana i tō taumahatanga mahi mōrahi me te tauwehenga haumaru paerewa - ko te tikanga he 6.7:1 mō ngā whitiki taura maitai i roto i ngā tono keri. Kōrero ki tā mātou tīma mō te tatau taumahatanga kore utu.

He aha te mea e hanga ana i tētahi AnnilteWhitiki Taura RinoHe rerekē?

1. Hangarau Hanga Taketake Tiamana

E 16 ngā raina whakaputa aunoa katoa a Annilte mā te whakamahi i ngā taputapu whakamomona werawera Tiamana. Ko ia tawhā whakaputa nui — te pāmahana, te pēhanga, te wā noho — ka aroturukitia, ka whakahaeretia hoki mā te mamati. Ko te tikanga o tēnei, ko ia mita o te whitiki e puta ana i tō mātou wheketere he raraunga whakaputa ka taea te whai.

2. Te whānuitanga ST katoa i raro i te tuanui kotahi

Mai i ST630 ki ST5400, ka hangaia e Annilte te whānuitanga katoa. Kāore he tuku mahi ki waho. Kāore "ka tirohia e mātou me tō mātou wheketere hoa." Ka hangaia e mātou te mea e hokona ana e mātou, arā, he poto ake te wā arahi me te kawenga tika.

3. I hangaia mō ngā Pae Tino Uaua o te Ao

Kua horahia ā mātou whitiki taura maitai puta noa i:

• Ngā maina koura me te parahi o Āwherika — ina neke atu i te 45°C te pāmahana o te taiao, ā, ko te utu mō te wā whakatā he $100,000+ ia hāora
• Ngā wheketere sima o te Tonga-mā-rāwhiti o Āhia — te whakahaere i te clinker whakakoi me te kaha whakaputa tere tonu
• Ngā mahi phosphate o te Waenganui Rawhiti — e hiahia ana ki ngā matū hipoki ātete-matū
• Ngā maina rino nunui o Amerika ki te Tonga — ngā kaikawe whenua he kiromita te roa, he 10,000 tana ia hāora te kaha
• Ngā taunga waro o Ahitereiria — e tutuki ana i ngā paerewa haumaru me te ātete ahi tino pakari o te ao

4. Ngā Matū Taupoki Ritenga

Ko te tinana o te whitiki he haurua noa iho o te kōrero. Ko te uhi rapa te mea e whakatau ana i te roa o te oranga o tō whitiki i roto i tō taiao. Ko tā Annilte e tuku nei:

Taumata Uhi	Kaha Kume	Pai rawa atu mō
A (Ātete ki te Waro)	18–25 MPa	Te keri whānui, ngā mea whakahiato
FR (Ātete Ahi)	15–20 MPa	Waro raro whenua, ngā kauhanga
RĀNEI (Ātete-Hinuhinu)	15–18 MPa	Ngā onepu hinu, ngā tipu matū
HR (Ātete Wera)	10–15 MPa	Te kirīni sima, te sinter, te pungarehu wera
CR (Ātete-Mātao)	18–25 MPa	Ngā mahi Arctic/iti iho i te kore (ki raro ki te -50°C)

Ka taea e tā mātou tīma R&D — 35 ngā kaihangarau me te 16+ tau o te tohungatanga ki te whitiki kawe — te hanga i ngā matū ritenga mō ngā āhuatanga whakahaere ahurei.

Tauira: Otinga Whakaritenga 3.4-Mita te Whānui

I te wā i hiahiatia ai e tētahi wheketere tukatuka koura he whitiki kawe kotahi-wahi e 3.4 mita te roa — tata ki te toru te whānui o te paerewa ahumahi — i kī te nuinga o ngā kaihanga "kāore e taea." I whakaae a Annilte. Ka pā tēnei whakaaro hangarau ki ngā whitiki taura maitai katoa e hangaia ana e mātou: he hua paerewa mō ngā hiahia paerewa, engari ehara i te mea he whakamārama paerewa ina hiahia koe ki tētahi mea rerekē.
