E matapaetia ana ka piki ake te mākete mō te hiko karāpeti i te CAGR neke atu i te 9% i roto i te wā matapae. Ko te rauemi mata matua e whakamahia ana mō te hanga hiko karāpeti ko te ngira kōka (he mea hanga mai i te hinu, he mea hanga mai i te waro rānei).
Ko te pikinga ake o te hanga rino me te maitai i roto i ngā whenua whanaketanga, me te pikinga ake o te waatea o te para maitai i Haina, ā, ko te whakapiki ake i te whakamahinga o ngā oumu hiko hiko e tika ana kia akiakihia te tono mo te maakete i roto i te wa matapae.
Ko te pikinga o ngā utu o te ngira coke e hua ake ana te iti o te tuku me ētahi atu aukati pēnei i te iti o te tipu o te hiko karāhe UHP i Haina me te whakakotahitanga o te umanga hiko karāhe, tera pea ka aukati i te tipu o te mākete.
Ko te pikinga ake o te hanga maitai mā te hangarau oumu pewa hiko i Haina e whakaarohia ana he whai wāhitanga mō te mākete a meake nei.
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 (rino wera, he DRI whakakīkī), 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 3,000 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 nā 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 mea hei whakakapi mō te hiko karāhe i roto i ngā mahi EAF.
- Hei tāpiritanga, 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 peia 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 rohe matua o te mākete o te ao. Ko Haina te rohe nui rawa atu mō te whakamahinga me te kaha whakaputa o ngā hiko karāhe i roto i te horopaki o te ao.
- Nā ngā kaupapa here hou i Beijing me ētahi atu kawanatanga nui o te whenua, ka akiakihia 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 karāwhata 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 ake nei, e tika ana kia piki ake te hiahia mō te hiko karāhe i te rohe i te wā matapae.
