Ngā Auahatanga Matua o te Mākete
Te Whakanui Ake i te Hanganga o te Rino mā te Hangarau Umu Āwhata Hiko
- Ka tangohia e te oumu hiko ngā para maitai, te DRI, te HBI (te rino wera kua whakakīia ki te para), te rino poaka rānei i te āhua totoka, ka whakarewahia hei hanga maitai. I te ara EAF, ka tukuna e te hiko te mana hei whakarewa i te rauemi kai.
- Ko te hiko karāpiti te mea e whakamahia nuitia ana i roto i te tukanga hanga maitai o te oumu pewa hiko (EAF), hei whakarewa i ngā para maitai. He karāpiti te mea hanga o ngā hiko nā te mea ka taea e ia te tu atu i ngā pāmahana teitei. I roto i te EAF, ka taea e te pito o te hiko te eke ki te 3,000º Fahrenheit, arā, te haurua o te pāmahana o te mata o te rā. He rerekē te rahi o ngā hiko, mai i te 75mm te whānui, ki te 750mm te whānui, tae atu ki te 2,800mm te roa.
- Nā te pikinga o te utu o ngā irahiko karāpiti i piki ake ai ngā utu o ngā mira EAF. E kiia ana ka pau i te EAF toharite te 1.7 kg o ngā irahiko karāpiti hei whakaputa i te kotahi tana mita o te maitai.
- Ko te pikinga o ngā utu e pā ana ki te whakakotahitanga o ngā umanga puta noa i te ao, te kati o te kaha i Haina, whai muri i ngā ture taiao, me te tipu haere o te hanga EAF puta noa i te ao. E matapaetia ana ka piki ake te utu hanga o te EAF mā te 1-5%, i runga i ngā tikanga hokohoko a te mira, ā, tera pea ka aukati i te hanga maitai, nā te mea kāore he whakakapi mō te hiko karāhe i roto i ngā mahi EAF.
- Hei tāpiri, kua whakakaha ake ngā kaupapa here a Haina ki te whakatau i te parahanga o te hau nā te kaha o te aukati i te tuku taonga, ehara i te mea mō te rāngai maitai anake, engari mō te waro, te konutea, me ētahi atu rāngai e whakaputa ana i te parahanga matūriki. Nō reira, kua tino heke te hanga maitai o Haina i ngā tau kua pahure ake nei. Heoi, e matapaetia ana ka pā pai tēnei ki ngā utu maitai me ngā mira maitai i te rohe, kia pai ake ai ngā hua.
- Ko ngā āhuatanga katoa kua whakahuatia ake nei, e tika ana kia akiaki i te mākete hiko karāhe i te wā matapae.
Te Rohe o Āhia-Moananui-a-Kiwa hei Mana i te Mākete
- Ko te rohe o Āhia-Moana-nui-a-Kiwa te rangatira o te mākete o te ao. Ko Haina te rangatira o te mākete e whakamahi ana me te kaha whakaputa i ngā hiko karāhe i roto i te ao whānui.
- Ko ngā kaupapa here hou i Beijing me ētahi atu kawanatanga nui o te whenua e akiaki ana i ngā kaihanga rino ki te kati i tētahi kaha whakaputa rino o te 1.25 miriona tana i hangaia mā te ara kino ki te taiao kia taea ai te whakaputa i tētahi kaha whakaputa rino hou o te 1 miriona tana. Nā ēnei kaupapa here i tautoko te nekehanga o ngā kaihanga mai i ngā tikanga tuku iho o te whakaputa rino ki te tikanga EAF.
- Ko te tipu haere o te hanga waka, me te tipu haere o te umanga hanga whare noho, e matapaetia ana ka tautoko i te hiahia ā-rohe mō ngā koranu kore-ferrous me te rino me te maitai, he mea pai tēnei mō te tipu o te hiahia mō ngā hiko karāpeti i ngā tau e haere ake nei.
- Ko te kaha whakaputa o nāianei o ngā irahiko karāhe UHP i Haina e tata ana ki te 50 mano tana mita ia tau. E matapaetia ana hoki ka kitea he tipu nui o te hiahia mō ngā irahiko UHP i Haina i roto i te wā roa, ā, e matapaetia ana ka kitea he kaha tāpiri neke atu i te 50 mano tana mita o ngā irahiko karāhe UHP i ngā wāhanga o muri mai o te wā matapae.
- Ko ngā āhuatanga katoa kua whakahuatia i runga ake nei, e matapaetia ana ka piki ake te hiahia mō te hiko karāhe i roto i te rohe i te wā matapae.
