Ka hangaia te huruhuru muka uku mā te whakarewa i te uku parakore teitei, te paura alumina, te paura silica, te onepu chromite me ētahi atu rauemi mata i roto i te oumu hiko ahumahi i te pāmahana teitei. Kātahi ka whakamahia te hau kōpeke hei pupuhi, hei miro rānei i te mīhini hei miro i te rauemi mata rewa kia rite ki te āhua muka, ka kohia te muka mā te kaikohi huruhuru muka hei hanga huruhuru muka uku. He rauemi whakamahana wera teitei te huruhuru muka uku, he māmā, he kaha teitei, he ātete pai ki te waikura, he iti te kawe wera, he ngāwari pai, he ātete pai ki te waikura, he iti te kaha wera me te pai o te whakamahana oro. E whai ake nei te whakaahuatanga o te whakamahinga o te huruhuru muka uku i roto i te oumu whakamahana:
(1) Haunga te auahi, te paipa hau me te raro o te oumu, ka taea te whakamahi i ngā paraikete huruhuru muka uku, i ngā waeine huruhuru muka uku rānei mō ētahi atu wāhanga o te oumu whakamahana.
(2) Ko te paraikete huruhuru muka uku e whakamahia ana mō te mata wera me waiho hei paraikete wero ngira, kia 25mm te matotoru, kia 128kg/m3 te matotoru. Mēnā ka whakamahia he muka uku, he papa rānei mō te paparanga mata wera, kaua e iti iho i te 3.8cm te matotoru, ā, kaua hoki e iti iho i te 240kg/m3 te matotoru. Ko te huruhuru muka uku mō te paparanga o muri he paraikete wero ngira, kia 96kg/m3 te matotoru. Ko ngā whakaritenga mō te muka uku, te papa rānei mō te paparanga mata wera: ina iti iho i te 1095℃ te pāmahana o te mata wera, ko te rahi mōrahi ko te 60cm×60cm; ina neke atu i te 1095℃ te pāmahana o te mata wera, ko te rahi mōrahi ko te 45cm×45cm.
(3) Me 280℃ te pāmahana ratonga o tētahi paparanga huruhuru muka uku kia teitei ake i te pāmahana mata wera kua tatauhia. Ko te tawhiti mōrahi o te punga ki te taha o te paparanga mata wera o te paraikete huruhuru muka uku kia 7.6cm.
Ka haere tonu tā mātou whakauru atu i te putanga e whai ake neihuruhuru muka ukumō te oumu whakamahana. Tēnā, kia mataara tonu mai.
