Te Whakamate: I muri i te hanganga o te paparanga whakakākahu ka tere te rumakina o te mekameka ki roto i te reo whakamātao, ā, ka tere te whakamatao hei whakapūmau i te paparanga whakakākahu me te whakanui ake i te pakeketanga.
Te whakamahana: Hei whakaiti i te ahotea o roto e puta ana i te wā o te tukanga tinei, me te whakanui ake i te pakari o te mekameka, ka mahia te maimoatanga whakamahana.
Te tukanga whakakāwai wai
Ko te whakakākā wai he tukanga hei whakapai ake i te mārō o te mata me te ātete ki te kakahu o te mekameka roera, he mea e tika ana mō ngā mekameka maitai waro. Ko ngā mahi motuhake koia ēnei:
Te whakamahana: Whakamahanahia te mekameka ki te pāmahana whakawera wai, ka whakatau i te pāmahana motuhake kia rite ki te rauemi me ngā whakaritenga o te mekameka.
Te Whakakākahu: Tōia te mekameka ki roto i tētahi mea whakakākahu, pērā i te wairewa konutai cyanide, ka whakakākahu mō tētahi wā.
Te tinei: Ka tere te rumakina o te mekameka warowaihā ki roto i te reo tinei, ā, ka tere te whakamatao hei whakapūmau i te paparanga warowaihā, hei whakanui hoki i te pakeketanga.
Te whakamahana: Hei whakaiti i te ahotea o roto e puta ana i te wā o te tukanga tinei, me te whakanui ake i te pakari o te mekameka, ka mahia te maimoatanga whakamahana.
Te arotautanga o ngā tawhā tukanga maimoatanga wera
He mea nui te arotau i ngā tawhā tukanga maimoatanga wera kia pai ai te mahi a ngā mekameka roera. Anei ētahi tawhā matua me ā rātou tikanga arotau:
Te pāmahana me te wā whakamātao
Ko te pāmahana tinei ka whakahaeretia i waenga i te 800-850℃, ā, me whakarerekē te pāmahana motuhake kia rite ki ngā rauemi mekameka me ngā whakaritenga tukanga. Ko te wā pupuri he 30-60 meneti te tikanga kia ōrite te pāmahana i roto i te mekameka.
Kōwhiringa reo tinei
Ko te kōwhiringa o te reo tinei ka whakawhirinaki ki ngā whakaritenga rauemi me te mahi o te mekameka. He tere te tere whakamatao o te wai matao, ā, he pai mō ngā mekameka e hiahia ana kia pakeke rawa; he puhoi te tere whakamatao o te hinu, ā, he pai mō ngā mekameka e hiahia ana kia pakari.
Te pāmahana me te wā whakamātao
Ko te pāmahana whakamahana i te nuinga o te wā kei waenganui i te 200-300℃, ā, ko te wā pupuri he 1-2 hāora te nuinga. Me whakarerekē te kōwhiringa o te pāmahana me te wā whakamahana kia rite ki ngā whakaritenga whakamahinga whakamutunga o te mekameka kia tutuki ai te taurite pai i waenga i te pakari me te mārō.
Te whiriwhiringa taputapu maimoatanga wera
He mea nui te whiriwhiri i ngā taputapu maimoatanga wera tika hei whakapai ake i te whai huatanga o te whakaputa me te kounga o te hua. Ko ngā taputapu maimoatanga wera noa ko:
Ngā taputapu tinei
Ouma whakamahana kanapa: he pai mō ngā mekameka roera me ngā whakaritenga kounga mata teitei.
Kaitahuri: he pai mō te whakaputa nui, ka taea te whakarite i te ōritetanga o te tukanga tinei.
Ngā taputapu whakakākahu
Ouma whitiki mata: he pai mō te whakaputa tonu, ka taea te whakahaere tika i te wā me te pāmahana o te warowaihā.
Ngā taputapu whakamahana
Ouma maimoatanga wera maha-kaupapa: ka taea te mahi i te maimoatanga tinei me te whakamahana i te wa kotahi hei whakapai ake i te whai huatanga o te whakaputa.
Te whakahaere kounga me te whakamātautau
Me tino tirotirohia te kounga me te whakamātautau i muri i te whakamahana i te mekameka roera kia tutuki ai ngā whakaritenga hoahoa. Ko ngā tikanga whakamātautau noa ko:
Whakamātautau mārō
He mea nui te whakamātautau pakeke hei aromatawai i te pānga o te maimoatanga wera o ngā mekameka roera. Ko te whakamātautau pakeke Rockwell, ko te whakamātautau pakeke Vickers rānei te mea e whakamahia ana hei whakamātautau i te pakeke o te mata me te pakeke o te mekameka.
