Te whakakikorua i te ahi-ahuru
KO TE MAHI O NGĀ PANIHANGA ĀRAI-AHI WHĀNUI, ĀRAI-PĀMAHANA-TEITEI, E WHAKAPĀ ANA KI NGĀ ĀHUATANGA E WHAI AKE NEI:
Ka whānui haere ina tūtaki ki te ahi, ka hanga he paparanga ārai wera whai hua: Koinei tana mahi matua. Ina pā te paninga ki te ahi, ka tere te tauhohe o ngā ārai mura o roto me ngā wāhanga pahuka, ka puta te rōrahi kia 5 ngā wā ki te 20 ngā wā, neke atu rānei; hei tauira, ka taea e tētahi hua te whānui haere 20 ngā wā ina 0.6mm te matotoru ina tūtaki ki te ahi, ka hanga he paparanga waro matotoru, he paparanga uku rānei. Ka taea e tēnei paparanga whānui te wehe i te wera me te hāora, ka whakaroa i te pikinga o te pāmahana o te papa. Ngā āhuatanga ātete pāmahana teitei me te ārai wera tino pai: Ka taea e ngā paninga whānui kounga teitei te tu atu i ngā pāmahana mura tino teitei. Hei tauira, ka taea e tētahi hua te pupuri i te pāmahana o muri kia kaua e neke ake i te 200℃ i roto i te 5 meneti ina pā te mura 1000℃; e whakaatu ana tētahi atu rangahau i te mura 850℃ mō te 15 meneti, ko te pāmahana matao o te mata he 122.3℃ anake. Ka taea e ētahi paninga motuhake te whai i te rohe ātete pāmahana tae atu ki te 2000℃. He tino iti te kawe wera o te hanganga pūngāwerewere, korehau rānei i hangaia i muri i te whakawhanuitanga (pērā i te 0.022W/mK), ā, ka hua ake he pānga whakamarumaru wera whakamiharo.
Mā te whakaroa i te whakawhiti wera mā roto i te paparanga whakamarumaru, ka taea te tiaki pai i ngā papa pēnei i ngā hanganga rino, me te pupuri i tō rātou kaha hanganga ahakoa i ngā pāmahana teitei. Mō te hanga hanganga rino, ka taea e tēnei te whakarato i te wā tiaki utu nui 1-3 hāora, neke atu rānei, mō te whakawātea i ngā kaimahi me te whakaora ahi.
Ngā āhuatanga ā-tinana me te matū pai: Ehara i te mea he ātete ahi anake ngā paninga momo-whanui hou, engari he tino kaha te piri (ka taea e ētahi te eke ki te taumata 0), te ātete ki te waikura waikawa me te kawakore, te ātete ki te huarere, me te ātete ki te pānga. Ko ētahi hua e whakamahi ana i ngā hanganga kore-whakarewa, wai-hāngai rānei, he pai mō te taiao, he iti hoki te paitini, e tutuki ana i ngā whakaritenga tiaki taiao o ēnei rā.
