1. Te Whakaōrite:
He tukanga whakamahana e whakamahanatia ai te maitai, ngā wāhanga rānei o te maitai ki te pāmahana e tika ana i runga ake i te pūwāhi matua AC3, ACM rānei, ka puritia mō tētahi wā, kātahi ka whakamataohia ki te hau kia puta he hanganga rite ki te pearlite.
2. Te whakamahana:
He tukanga whakamahana e whakamahanatia ai ngā konganuku maitai hypoeutectoid ki te 20-40 nekehanga i runga ake i te AC3, ka pupuri kia mahana mō tētahi wā, kātahi ka whakamatao mārire i roto i te oumu (ka tanumia rānei ki te onepu, ka whakamatao rānei ki te raima) ki raro iho i te 500 nekehanga i te rangi.
3. Te maimoatanga wera o te wai totoka:
He tukanga whakamahana e whakamahanatia ai te koranu ki te pāmahana teitei, ka puritia hoki ki te pāmahana pumau i roto i te rohe kotahi-wāhanga kia memeha katoa ai te wāhanga taikaha ki roto i te wairewa totoka, kātahi ka whakamatao wawetia kia puta he wairewa totoka kua tino mākūkū.
4. Te koroheketanga:
I muri i te maimoatanga wera o te wai totoka, i te whakarerekētanga kirihou matao rānei, ka rerekē ōna āhuatanga i te wā e whakanohoia ana ki te pāmahana rūma, ki runga ake rānei i te pāmahana rūma.
5. Maimoatanga wairewa totoka:
ka whakarewa katoa i ngā wāhanga rerekē i roto i te koranu, ka whakapakari i te otinga totoka me te whakapai ake i te pakari me te ātete ki te waikura, ka whakakore i te ahotea me te whakangawari, kia haere tonu ai te tukatuka me te hanga
6. Maimoatanga koroheketanga:
Te whakamahana me te pupuri i te pāmahana e mimiti haere ai te wāhanga whakapakari, kia mimiti haere ai, kia mārō ai te wāhanga whakapakari, kia pai ake ai te kaha.
7. Te tinei:
He tukanga whakamahana e whakaaustenitihia ai te maitai, kātahi ka whakamataohia i te tere whakamatao e tika ana kia puta ai he panonitanga hanganga kore pumau o te mea mahi pērā i te martensite i te katoa, i roto rānei i tētahi awhe kua whakaritea o te wāhanga whakawhiti.
8. Te whakamahana:
He tukanga whakamahana e whakamahanatia ai te mea mahi kua tineia ki te pāmahana e tika ana i raro i te pūwāhi matua AC1 mō tētahi wā, kātahi ka whakamataohia mā te whakamahi i tētahi tikanga e tutuki ai ngā whakaritenga hei whiwhi i te hanganga me ngā āhuatanga e hiahiatia ana.
9. Te whakakāhoretanga o te maitai:
Ko te whakapūtanga waro te tukanga o te whakauru i te waro me te hauota ki roto i te paparanga mata o te maitai. I ngā wā o mua, ko te whakapūtanga waro te ingoa o te cyanidation. I tēnei wā, e whakamahia whānuitia ana te whakapūtanga waro hau pāmahana-waenga me te whakapūtanga waro hau pāmahana-iti (arā, te whakapūtanga hau ngohengohe). Ko te kaupapa matua o te whakapūtanga waro hau pāmahana-waenga ko te whakapai ake i te pakeke, te ātete ki te kakahu me te kaha ngenge o te maitai. Ko te whakapūtanga waro hau pāmahana-iti ko te whakapūtanga waro, ā, ko tōna kaupapa matua ko te whakapai ake i te ātete ki te kakahu me te ātete ki te hopu o te maitai.
10. Te tinei me te whakamahana:
Ko te tikanga whānui ko te whakakotahi i te tinei me te whakamahana i te pāmahana teitei hei maimoatanga wera e kiia nei ko te tinei me te whakamahana. He whānuitia te whakamahinga o te maimoatanga tinei me te whakamahana i roto i ngā wāhanga hanganga nui, inā koa ko ngā tokotoko hono, ngā pūtu, ngā taputapu me ngā pou e mahi ana i raro i ngā kawenga tauutuutu. I muri i te maimoatanga tinei me te whakamahana, ka whiwhihia te hanganga sorbite whakamahana, ā, he pai ake ōna āhuatanga miihini i ērā o te hanganga sorbite kua whakaritea me te pakeke ōrite. Ko tōna pakeke e whakawhirinaki ana ki te pāmahana whakamahana pāmahana teitei, ā, e pā ana ki te pumau o te maitai me te rahi whakawhiti-wāhanga o te mea mahi, i waenga i te HB200-350.
11. Te whakakā:
He tukanga whakamahana e whakamahi ana i te rauemi whakakā hei hono i ngā wahi mahi e rua.
