Ko ngā oumu whakarewa konganuku kore-ferrous ngā taputapu matua mō te whakarewa konganuku kore-ferrous. Ko te ako i te hiahia mō te momo me te kounga o ngā rauemi ātete-wai nā te ahunga whakamua hangarau o te umanga whakarewa konganuku kore-ferrous te mahi matua mā te umanga ātete-wai kia roa ake ai te ora o ngā oumu whakarewa konganuku kore-ferrous me te whakanui ake i te whakaputanga.
1. Te umanga whakarewa parahi
Ko te tukanga whakaputa parahi te mea he maha ngā tikanga mō ngā momo konganuku kore-ferrous. Ehara i te mea ko ngā tukanga parahi katoa o te ao anake te tukanga whakaputa parahi i tōku whenua, engari kei roto hoki ngā tukanga ahurei i tōku whenua, pērā i te tikanga whakarewa hiriwa me te raro hāora. Te oumu rewa pupuhi.
I roto i te tukanga whakarewa parahi ahi, ko te rerekētanga kei te hanga i te parahi matte, ko te pupuhi o te kaitahuri me te whakamahine parahi he rite tonu.
Nā te pāmahana teitei o te pourewa tauhohenga o te oumu mura, ka memeha, ka waikura te pourewa tauhohenga nā te hau tere-rahi i konatunatua ki te hau rewa. I tēnei wā, e whakamahia ana ngā pereki konupūmā-kōromo kua hanumi. I taua wā anō, hei tiaki i ngā pereki konupūmā-kōromo kua hanumi, he maha ngā paparanga o ngā uhi wai pereti parahi whakapae kua whakatakotoria ki roto i te papa pereki, ā, ka whakaritea ngā paipa parahi whakamatao-wai, ngā uhi wai pereti parahi poutū rānei i waenganui i te papa pereki me te anga. , ko te tihi o te pourewa tauhohenga me te wāhi pāmahana iti o runga kua hangaia ki ngā pereki konupūmā-kōromo noa. I te wāhanga hononga i waenganui i te pourewa tauhohenga me te tihi o te tāke whakatō (pērā i te hononga i waenganui i te tāke whakatō me te hau e piki ake ana), ka pāngia e te memeha me te waikura kaha o te hau rewa pāmahana-teitei me te hau pāmahana-teitei kua ki tonu i te puehu, ā, ka ngawari te pakaru o te arai, nō reira ka whakamahia te parahi whai tara. Ko te hanganga o ngā pereki konupūmā-kōromo kounga teitei kua whakauruhia ki ngā paipa whakarewa ātete-whakapiri, ngā uhi wai parahi rānei.

2. Ahumahi mata me te konutea
Ouma pupuhi hau-konutea mata
He oumu pupuhi motuhake te oumu pupuhi hau mata-konutea e whakarewa ana i ngā konganuku e rua, te mata me te konutea i te wā kotahi i roto i te taputapu kotahi. Ko ōna āhuatanga ko te hau wera 800-850 ℃ e whakamahia ana mō te pupuhi; ka pupurihia te tihi o te oumu ki te pāmahana teitei o te 1050-1100 ℃; Ko te takuahi o te oumu pupuhi hau mata-konutea he mea hanga ki ngā pereki konupora, he uhi wai te takuahi, ko te tinana o te oumu he mea hanga ki ngā pereki alumina-nui, ā, ko te tihi o te oumu he mea here ki ngā rauemi ātete kore-ahua alumina-nui. Ko ngā moenga o mua o ngā oumu pupuhi hau mata-konutea he moenga whakamahana hiko katoa, ā, he iti ake te roa o te mahi i tērā o ngā oumu pupuhi. Ko te nuinga o te take he horo para me ngā raina para horoi. I tēnei wā, e rua ngā oumu pupuhi hau mata-konutea i Haina kua whakakikoruatia ki ngā pereki para chrome me ngā pereki konumohe-chromium-titanium. Ahakoa ka taea e te oumu te neke atu i te 1 tau, he iti iho tonu i te roanga o te ora o ngā oumu hauhautanga mata-konutea. Ko te mea nui ki te whakapai ake i te tere mahi o te oumu hauhautanga mata-konutea te whakapai ake i te ora o te oumu hauhautanga mata-konutea.
