He Kupu Whakataki ki ngā Koranu Whakamahana
I te wā e whiriwhiri ana i ngā rauemi mō ngā huānga whakamahana, e rua ngā koranu e whakaarohia ana:Nichrome(Nikara-Kōromā) meFeCrAl(Rino-Kōromā-Arumīni). Ahakoa he rite tonu ngā mahi a ēnei e rua i roto i ngā whakamahinga whakamahana ātete, he āhuatanga motuhake ō rāua e pai ai mō ngā taiao me ngā whakamahinga rerekē. He mea nui te mārama ki ēnei rerekētanga hei whiriwhiri i te rauemi tika mō ō hiahia.
1. Te Hanganga me ngā Āhuatanga Taketake
He koranu nikara-konukōmiuma te nikara, ā, ko te nuinga o te wā kei roto ko te 80% nikara me te 20% konukōmiuma, ahakoa he rerekē ngā ōwehenga. He pai te ātete o tēnei huinga ki te waikura, ā, ka mau tonu te kaha i ngā pāmahana teitei. E mōhiotia ana ngā koranu nikara mō tō rātou ngāwari ki te hanga me te mahi pumau puta noa i te whānuitanga o te pāmahana.
E ai ki te ingoa, ko ngā koranu FeCrAl he mea hanga nui mai i te rino (Fe) me te nui o te chromium (Cr) me te konumohe (Al). Ko te hanganga noa pea he 72% te rino, 22% te chromium, me te 6% te konumohe. Ko te nui o te konumohe ka tino whakarei ake i te mahi pāmahana teitei me te ātete ki te waikura.
2. Te Mahi o te Mahana
Ko tētahi o ngā rerekētanga nui ko ō rātou pāmahana mahi mōrahi:
- Ko te tikanga ka mahi te nichrome tae atu ki te 1200°C (2192°F)
- Ka taea e te FeCrAl te tu atu i ngā pāmahana tae atu ki te 1400°C (2552°F)
Nā tēnei ka pai ake te FeCrAl mō ngā tono e hiahia ana ki te wera nui, pērā i ngā oumu ahumahi, i ngā taputapu taiwhanga pāmahana teitei rānei.
3. Ātete Waikura
Ka hangaia e ngā koranu e rua ngā paparanga waikura tiaki, engari mā roto i ngā tikanga rerekē:
- Ka hangaia e te nichrome he paparanga waikura chromium
- Ka whakawhanakehia e te FeCrAl he paparanga waikura konumohe (alumina)
He pumau ake te paparanga alumina i roto i te FeCrAl i ngā pāmahana tino teitei, ā, he pai ake te tiaki mō te wā roa mai i te waikura me te waikura. Nā tēnei ka tino whai hua te FeCrAl i roto i ngā taiao kei reira ngā huānga waikura pea.
4. Ātete Hiko
Ko te tikanga he nui ake te ātete hiko o te nichrome i te FeCrAl, ko te tikanga:
- Ka taea e te nichrome te whakaputa wera nui ake me te nui o te iahiko ōrite
- Tērā pea ka hiahiatia he iahiko nui ake mō te FeCrAl mō te whakamahana ōrite
Heoi, ka nui ake te pikinga o te ātete o FeCrAl i te pāmahana, ā, he mea whai hua tēnei mō ētahi tono whakahaere.
5. Ngā Āhuatanga Ā-Mīhini me te Āhuatanga Hanga
He māmā ake te whakamahi i te nichrome i te pāmahana rūma, ā, he pai ake mō ngā tono e hiahia ana ki ngā āhua uaua, ki ngā piko kikī rānei. Ka ngāwari ake te whakamahi i te FeCrAl ina werahia, he mea whai hua pea i te wā o ngā tukanga hanga engari me whakamahi motuhake i te pāmahana rūma.
6. Ngā Whakaaro mō te Utu
He iti ake te utu o ngā koranu FeCrAl i ngā koranu Nichrome nā te mea he utu nui hei whakakapi i ngā koranu koranu.nikarame te rino. Nā tēnei painga utu, me te mahi pāmahana teitei pai rawa atu, ka waiho te FeCrAl hei whiringa ātaahua mō ngā tono ahumahi maha.
He aha i whiriwhiri ai koe i ā mātou hua FeCrAl?
Ko ā mātou huānga whakamahana FeCrAl e tuku ana i:
- He pai rawa te mahi pāmahana teitei (tae atu ki te 1400°C)
- He ātete pai rawa atu ki te waikura me te waikura
- He roa ake te ora ratonga i roto i ngā āhuatanga tino kino
- He huarahi utu iti hei whakakapi i ngā koranu e hangai ana ki te nikara
- Ngā otinga ka taea te whakarite mō ō hiahia tono motuhake
Ahakoa kei te hoahoa koe i ngā oumu ahumahi, i ngā pūnaha whakamahana, i ngā taputapu motuhake rānei, ka whakaratohia e ā mātou hua FeCrAl te pakari me te mahi e hiahiatia ana mō ngā taiao uaua.Whakapā maii tēnei rā hei matapaki me pēhea e taea ai e ā mātou otinga FeCrAl te whakatutuki i ō hiahia huānga whakamahana me te whakapai ake i ō utu whakahaere.
