Roera Ukume Alumina
Ngā Mōhiohio Hua
Ngā roera uku aluminahe hua uku ahumahi mahi-teitei te nuinga he mea hanga ki te alumina (Al₂O₃), ā, he wāhanga matua o ngā oumu roera pāmahana-tiketike o ēnei rā.
Te Hanganga o ngā Rauemi:I te nuinga o te wā, ko te ihirangi alumina he ≥95% hei whakarite i te mahi pāmahana teitei me ngā āhuatanga hangarau tino pai.
Ngā Āhuatanga o te Hua:
Teitei o te Pakari:Ko te pakeke o Rockwell he HRA80-90, ko te tuarua anake i te taimana, he nui atu i te ātete kakahu o te maitai ātete kakahu me te maitai kore waikura.
Ātete Pakakahu Pai rawa atu:He rite te ātete kakahu ki te 266 ngā wā i te maitai manganese me te 171.5 ngā wā i te rino maka konupora-tiketike, e whakaroa ana i te ora o ngā taputapu kia tekau ngā wā neke atu rānei.
Mama:Ko tōna mātotoru he 3.6 karamu/cm³, he haurua noa iho i te mātotoru o te maitai, ka tino whakaiti i te kawenga o ngā taputapu.
Ātete ki te pāmahana teitei:He tino ātete ki te pāmahana teitei, me te pāmahana mahi mōrahi o te 1600℃. I te wa ano, he tino pono te pumau o te wera me te ātete ki ngā ru wera mō ngā hua e tahuna ana tae atu ki te 1400℃.
Ngā Whakatakotoranga:Ko te whānuitanga whānui ko te 12-80mm, ko te roa ko te 1200-5300mm, ā, e wātea ana te whakaritenga kia rite ki ngā oumu rerekē me ngā hiahia whakaputa.
Ngā Whakatūpato Whakamahinga:Me whakakī ngā kōhao o roto i ngā pito e rua o te roera ki te miro muka ātete. Me pani he paninga tiaki i mua i te urunga ki te oumu, ā, me waiho kia maroke rawa. I te wā e whakamahia ana, me horoi tonu ngā toenga o te mata. I te wā e whakakapi ana i ngā roera, kia aro ki te tere me te tikanga whakamatao kia kore ai e pakaru i te tere o te whakamahana, te whakamatao rānei.

1. Te Ahumahi Uku Whare:Koinei te wāhi matua e whakamahia ana mō ngā roera uku alumina. I roto i te tukanga tahu oumu roera o ngā uku hoahoanga pēnei i ngā taera pakitara, ngā taera papa, ngā taera tawhito, me ngā taera tinana-roto, ka tautoko tika ngā roera i ngā papa uku, ka tutuki ai te tuku pumau i ngā pāmahana teitei (te nuinga o te 1200–1450℃) kia rite ai te whakamahana me te tahu o ngā hua whai tohu.
2. Te Ahumahi Uku Whakamahinga o Ia Rā:E whakamahia ana i roto i ngā oumu tahu wera-teitei mō ngā uku o ia rā pērā i ngā peihana, ngā pereti, ngā kapu, me ngā pereti iti, tae atu ki ngā taputapu horoi uku (wharepaku, oko horoi, me ētahi atu). Mā ngā āhuatanga whakawhanui wera iti o ngā roera ka ārai i te rerekētanga, te pakaru rānei i puta mai i ngā huringa pāmahana ohorere, kia mau ai te āhua me te pumau o te kounga o ngā hua uku o ia rā.
3. Te Ahumahi Uku Motuhake me ngā Rauemi Ātete:He pai mō ngā oumu whakawera wera-teitei mō ngā uku motuhake ahumahi (pēnei i ngā ārai uku, ngā taputapu uku, ngā wāhanga uku hanganga), ngā pereki ātete wera, me ngā kōwae rauemi ātete wera. Me nui ake te ātete pāmahana teitei o ngā roera mō ēnei mahi; ka taea e ngā roera uku alumina he nui te ihirangi alumina (≥95%) te tu atu i ngā pāmahana tino tiketike o te 1600℃.
4. Ahumahi Tukatuka Hōhonu Karāhe:I roto i ngā oumu whakamahana karāhe me ngā taputapu kawe roera wāhanga whakamahana mō te hanga karāhe whakamahana, ka taea e ngā roera uku alumina te whakakapi i ngā roera whakarewa, ka ārai i ngā roera whakarewa kei piri ki te mata karāhe i ngā pāmahana teitei. I te wā kotahi, ko tō rātou ātete kakahu pai ka roa ake te roa o te ora o ngā taputapu, ā, ka whakarite kia maeneene te mata o ngā hua karāhe.
5. Ahumahi Uku Hiko:Whakamahia ana i roto i te tukanga tahu pāmahana teitei o ngā wāhanga uku hiko (pērā i ngā pūnga uku, ngā uku piezoelectric, me ngā uku aukume). He tino kaha ngā whakaritenga o ngā uku hiko mō te pumau o te taiao tahu. Ko te iti o te ru wera me te koretake o ngā matū o ngā roera uku alumina ka ārai i ngā roera kei poke i ngā wāhanga uku, kia tutuki ai ngā paerewa o ngā tawhā mahi o ngā wāhanga hiko.
