Irahiko karāpitiKo te nuinga o te wā e whakamahia ana i roto i te hanga maitai EAF. Ko te hanga maitai oumu hiko he whakamahi i te hiko karāpeta hei whakauru i te iahiko ki roto i te oumu. Ka puta he rerenga pewa mā te hau i te pito o raro o te hiko mā te iahiko kaha, ā, ka whakamahia te wera e puta mai ana i te pewa hei whakarewa. E ai ki te kaha o te oumu hiko, ka whakamahia ngā hiko karāpeta me ngā diameter rerekē. Hei whakamahi tonu i ngā hiko, ka honoa ngā hiko mā te hononga miro hiko. Ko tehiko karāpetiMō te hanga maitai, e 70-80% o te tapeke o te irahiko karāpeti e whakamahia ana. 2. Ka whakamahia i roto i te oumu wera o te maina. Ko tōna āhuatanga ko te wāhanga o raro o te irahiko kawe hiko e tanumia ana ki roto i te utu. Nō reira, hei tāpiri atu ki te wera e puta mai ana i te pewa i waenganui i te pereti hiko me te utu, ka puta hoki te wera e te ātete o te utu ina puta te iahiko i roto i te utu. 3. Ko te oumu karāpeti, te oumu rewa karāhe me te oumu hiko mō te whakaputa hua karāpeti he oumu ātete katoa. Ehara i te mea he ātete wera anake ngā rauemi o roto i te oumu, engari he mea whakamahana anō hoki. I te nuinga o te wā, ka whakauruhia te irahiko karāpeti kawe hiko ki roto i te pakitara o te upoko oumu i te pito o te takuahi, kia kore ai e pau tonu te irahiko kawe hiko.
Ngā āpure tono:
(1) E whakamahia ana i roto i te oumu hanga maitai pewa hiko, he mea whakamahi nui tēnei ihiko karāpetiI Haina, ko te putanga o te maitai EAF e 18% o te putanga maitai mata, ā, ko te hiko karāpiti mō te hanga maitai e 70% ~ 80% o te katoa o te whakamahinga o te hiko karāpiti. Ko te hanga maitai oumu hiko he whakamahi i te hiko karāpiti hei whakauru i te iahiko ki roto i te oumu, ā, mā te whakamahi i te pūtake wera pāmahana teitei i hangaia e te pewa i waenganui i te pito o te hiko me te utu hei whakarewa.
2) E whakamahia ana i roto i te oumu pewa raro; ko te oumu pewa raro te nuinga o te whakamahinga mō te hanga i te silicon ahumahi me te phosphorus kōwhai, me ētahi atu. Ko tōna āhuatanga ko te wahi o raro o te irahiko kawe hiko e tanumia ana ki roto i te utu, ka hanga he pewa i roto i te paparanga utu, ā, ka whakamahana i te utu mā te whakamahi i te kaha wera i hangaia e te ātete o te utu tonu. Ko te oumu pewa raro he nui ake te mātotoru o te iahiko me whai irahiko karāhe, hei tauira, e hiahiatia ana te 100kg irahiko karāhe mō ia 1t hanga silicon, ā, e hiahiatia ana te 100kg irahiko karāhe mō ia 1t hanga silicon. Tata ki te 40 kg o te irahiko karāhe e hiahiatia ana mō te t phosphorus kōwhai.
(3) E whakamahia ana mō te oumu ātete; ko te oumu whakakāwhata mō te hanga hua karāhe, te oumu mō te whakarewa karāhe me te oumu hiko mō te hanga karāhe silicon, nō te oumu ātete katoa. Ko ngā rauemi o te oumu he ātete wera me he mea wera. Ko te tikanga, ko te hiko karāhe kawe hiko kei roto i te pakitara o te upoko oumu i te pito o te oumu ātete, ā, kāore te hiko karāhe e whakamahia ana i konei e pau tonu ana.
(4) E whakamahia ana hei whakarite i ngā mea āhua motuhakengā hua karāhe; ka whakamahia hoki te papa o te irahiko karāhe hei tukatuka i ngā hua karāhe āhua motuhake pērā i te para, te pokepokea ai, te rihi poti me te tinana whakamahana. Hei tauira, i roto i te umanga karāhe kuata, e hiahiatia ana he papa irahiko karāhe 10t mō ia ngongo rewa hiko 1t; e hiahiatia ana he papa irahiko karāhe 100kg mō ia pereki kuata 1t.
