Mō ngā ahumahi hanga rino me te whakarewa kore-ferrous e rapu ana i ngā otinga ātete pakari, utu-pai, kounga teiteipereki waro konupūmā (MgO-C)Ko te mea tino pono. He mea hanga ki te konupūmā konupūmā kounga teitei, te karāpeti maramara, ngā ārai mate motuhake me ngā here kapia kaha-teitei, ka tukuna e ā mātou pereki waro konupūmā konupūmā he mahi tino pai i roto i ngā taiao matū tino wera me te kino, ka noho hei rauemi whakapuru matua mō ngā oumu ahumahi hou.
Ko te painga nui o ā mātou pereki waro konupūmā kei roto i ō rātou āhuatanga ātete-whakarewa tino pai. He tino kaha ātete-whakarewa, he pumau ki ngā pāmahana mahi tonu i runga ake i te 1700°C me te kore e whakarerekē i te hanganga, e pakaru rānei. He rerekē i ngā pereki ātete-whakarewa noa, ko te whakakotahitanga ahurei o te konupūmā me te karāpeti he ātete tino pai ki te waikura para me te kaha ki te ārai i te urunga. Ka hangaia e te wāhanga karāpeti he mata kore-mākū ki te maitai rewa me ngā momo para, ka ārai pai i te mimiti o ngā para kawakore me ngā para rino, ka whakaiti nui i te kakahu o te arai oumu i roto i te hanga roa.
Ko tētahi atu āhuatanga matua o ā mātou hua ko te ātete pai ki ngā ru wera. He maha ngā wā ka tere te whakamahana me te whakamatao o ngā oumu ahumahi, ka ngawari te pakaru me te pakaru o ngā pereki. He iti te tauwehenga whānui wera o ā mātou pereki waro konupūmā me te kawe wera teitei, ka taea te whakaiti i te ahotea wera o roto, te karo i te kiri me te pakaru, me te pupuri i te pumau o te hanganga i ngā huringa pāmahana nui. I taua wā, ko te tāpiri o ngā antioxidants tino whai hua ka whakanui ake i te ātete waikura o ngā wāhanga waro, ka roa ake te ora o ngā pereki i roto i ngā taiao hauropi pāmahana teitei.
He whānuitia te whakamahinga i roto i ngā āhuatanga ahumahi kanorau, he pai rawa ā mātou pereki waro konupūmā mō ngā wāhanga matua o ngā oumu hāora taketake (BOF), ngā oumu pewa hiko (EAF), ngā koko maitai me ngā rihi whakarewa tonu. He tino pai hoki ēnei mō te whakapuru i ngā oumu whakarewa mō te parahi, te nikara me ētahi atu konganuku kore-ferrous, tae atu ki ngā taputapu pāmahana teitei i roto i te hanga sima me te raima. E whakaatu ana te manatoko ahumahi mahi ka taea e ā mātou pereki te whakaiti i te wā kore mahi tiaki taputapu tata ki te 40% ki te whakataurite ki ngā rauemi ātete tuku iho, ka whakapai ake i te pai o te whakaputa me te whakaiti i ngā utu whakahaere whānui.
Ka piri mātou ki ngā paerewa whakahaere kounga whakaputa tino pakari, ka whakarato i ngā pereki waro konupūmā ritenga o ngā momo rerekē hei whakatutuki i ngā whakaritenga āhua mahi rerekē. Ahakoa mō te hanga maitai taumaha, mō ngā taiao whakarewa kore-ferrous motuhake rānei, ka tukuna e ā mātou hua he mahi pumau, he roa te mau me te utu whakamiharo. Kōwhiria ā mātou pereki waro konupūmā kounga teitei hei whakapai ake i tō pūnaha whakapuru oumu me te whakanui ake i ō painga whakaputa ahumahi.
