Kei te rapu koe i ngā otinga pono mō ngā taiao ahumahi pāmahana teitei?Ngā pereki ahi SK34ko te whiringa pono mō te mahi whakarewa, te hanga karāhe, te hanga uku, me tua atu. He mea hanga ki te hanganga matū tika me te mahi wera pai rawa atu, ka tukuna e ēnei pereki he pakari me te whai huatanga tino pai, ka noho hei tūāpapa mō ngā oumu me ngā oumu mahi-teitei puta noa i te ao.
1. Ngā Āhuatanga Matua o ngā Pereki Ahi SK34
E kitea ana ngā pereki ahi SK34 mō te pumau o te wera, te kaha miihini, me te ātete ki te waikura, e ahu mai ana i ngā mahi hanga matatau me ngā ranunga rauemi kua whakatikatikaina. Ko ngā āhuatanga matua ko:
- Te Ātete Tino Pai ki te Pāmahana Nui:He SK34 te whakatauranga (he ātete ki te wera i waenga i te 1710–1750°C) me te ātete ki te wera i raro i te kawenga (RUL) i te 0.2 MPa, ā, he pono te mahi i roto i ngā mahi pāmahana waenga-ki-teitei, me te kore e whakangawari, e whakarerekē rānei i te āhua, he mea nui mō te tukatuka wera tonu.
- Te Hanga Matū Arotau:Kei roto i te 34–42% alumina (Al₂O₃) me te <2.5% waikura ferric (Fe₂O₃), ka ātete rātou ki te horo o te para waikawa, ka whakaiti hoki i ngā kino e pā ana ki te poke, ka roa ake te ora o te mahi i roto i ngā taiao ahumahi uaua.
- Hanganga Kaha, Kikī hoki:He matotoru te papatipu o te 2.15–2.20 g/cm³ me te kaha kuru matao ≥30 MPa, ā, ka ātete ki te pakū me te pānga. Ko te iti o te porosity (19–23%) ka whakaiti i te ngaronga wera me te ārai i te urunga o te rauemi rewa, ka tiakina te pumau o te hanganga.
- Te Pūmautanga Pai rawa atu i te Ru Wera:E whakamanamana ana ki te 0.6% te whānui rārangi i te 1000°C me te ±0.3% te huringa rārangi tuturu i te 1350°C (2 hāora), ka tu atu rātou i ngā piki me ngā heke o te pāmahana, kāore e ngatata, e pakaru rānei, ka whakaiti i te wā tiaki me te wā kore mahi.
- Te Rahi Ngāwari:E wātea ana i ngā rahi paerewa (230×115×25 mm, 230×115×75 mm) me ngā āhua ritenga (āwhata, pereki kōpaka), ka uru ki ngā taputapu whakamahana paerewa me ngā taputapu whakamahana motuhake, e whakarei ake ana i te ngāwari o te whakamahinga.
2. Ngā Whakamahinga Ahumahi Matua
Nā te taurite o te mahi a ngā pereki ahi SK34, he mea nui ēnei mō ngā rāngai matua:
Te Whakarewa:Ka whakarārangihia ngā oumu pewa hiko, ngā oumu whakapūngao, ngā koko, me ngā oumu whakamahana anō i roto i te hanga maitai/rino, ka ātete ēnei ki te konganuku rewa me te horo o te para, kia pumau ai ngā tukanga whakarewa.
Karāhe me ngā Uku:He mea tino pai mō ngā oumu rewa karāhe me ngā oumu uku, nā te mea he ātete teitei ki te pāmahana me te pumau o te wera, ka mau tonu te wera ōrite, he mea nui mō te kounga o te hua i roto i te hanga karāhe me te whakahinuhinu uku.
Mana Matū me te Mana Wera:Ka whakamahia ki roto i ngā arai o ngā tauhohenga matū, ngā tahunga para, me ngā rūma tahunga o ngā poihau, ka ātete ki ngā hau waikura me ngā pāmahana tiketike, kia pai ai te mahi.
Ētahi atu Rāngai:Ka whakamahia hoki ki ngā kapu whakarewa, ki ngā oumu pereki, me ngā pūnaha whakamahana ahumahi, kia urutau ai ki ngā hiahia ahumahi pāmahana teitei kanorau.
Kōwhiria ngā pereki ahi SK34 mō te mahi kua whakamātauhia i roto i te wera nui. Ka tutuki ā mātou hua i ngā paerewa kounga o te ao, me ngā otinga whakarite kia rite ki ō hiahia. Whakapā mai i tēnei rā ki te ako me pēhea te whakapai ake i te whai huatanga me te roa o te ora o ō taputapu e ngā pereki ahi SK34.
