Ko te rauemi matua o te whakamaroke alumina kua whakahohehia ko te paura hauwai konumohe kounga ahumahi, he momo waikura taketake me te ihirangi wai 3-5%, ā, ko te whakahekenga tahunga o te hauwai alumina i te 900-1100 ℃ he 34.5%.
Ko te tukanga whakaputa o te whakamaroke alumina kua whakahohehia penei:
Te whakamaroke i te hauwai konumohe – te whakamaroke – te mira ki te 600 mata, te whakamaroke tere i te hauwai konumohe 300 ℃ – te whakakoi kōpae – te maimoatanga whakahohenga 12 hāora – mā te oumu rakau 550 ℃ te whakakoi.
1. Ka whakamaroketia te paura konumohe hauwai ā-ahumahi, kei roto nei te 3-5% o te makuku, i te 120℃ mā roto i ngā taputapu whakamaroke nui.
2. I muri i te maroke, ka uru te paura konumohe hauwai ki roto i te hurihanga ā-ringa nui, ka kuruhia kia 600 mata. Ko te pai ake o te pai, ko te pai ake o te hanga hei tukanga whakahohe pōro. Kāore he paura o ngā matūriki porowhita e puta ana, ā, he kaha rawa.
3, paura konumohe hauwai, ki roto i te pūnaha whakakore hau tere mō te sintering tuatahi, paura konumohe hauwai pai rawa atu i roto i te rere hau wera tino pōrearea noho 0.10s, ko te mātāpono whakaputa ko: ko te hauwai konumohe mā te whakatārewatanga tunua tere maroke, me te whakamatao tere.
4, mā te whakamahi i te mātāpono o te pōro hukarere, ka taea te hanga i te pōro alumina whakahohe, ka taea te hanga i tēnei tukanga i ngā diameter rerekē o te whakamaroke alumina whakahohe me te kawe.
5, ka waiho te pōro o ngā matūriki alumina whakahohe kia mau tonu mō ngā haora 12, ka whakahohe i tōna ake wera me te wai.
6. Hei whakamutunga, ka whakawerahia te alumina whakahohe ki roto i te oumu poutū, ā, ko te pāmahana tunu he 550-700℃.
