Ko te hanga maitai whakawhiti te tukanga matua o te hanga rino me te maitai hou, e mahi ana i raro i ngā āhuatanga tino uaua—te pāmahana tae atu ki te 1800°C, te horonga miihini nui mai i te maitai me te para rewa, te waikura matū nui mai i te para, me te ru wera pinepine. He mea nui ngā rauemi ātete tika hei tiaki i te anga whakawhiti, hei whakarite i te hanga pumau, hei whakapai ake i te kounga maitai, me te whakaroa i te roa o te wā o te oumu. Kei raro nei he tirohanga taipitopito o ngā rauemi ātete matua e hiahiatia ana mō ngā rohe mahi rerekē o te whakawhiti.
Ngā Pereki Konupora-Waro (MgO-C)
Ko ngā pereki konupūmā-waro (MgO-C) te rauemi ātete matua mō te nuinga o ngā rohe whakawhiti, ā, koia te arai mahi matua. He mea hanga mai i te konupūmā kua whakaranua kia tino parakore, te karāpiti kounga teitei, ngā here kapia phenolic, me ngā tāpiringa ārai mate, ka whakakotahi i te ātete pai o te konupūmā ki te para me te ātete kaha o te karāpiti ki te ru wera.
Ka taea te whakarite i ngā momo pereki konupūmā-waro rerekē mō ngā wāhi motuhake:ngā pereki konupūmā-waro-teitei (16-20% te ihirangi waro)e whakamahia ana i roto i ngā rohe o te para me ngā rohe o te poro hei ātete i te horo nui, i te wāngā momo waro-waengahe pai mō ngā pakitara taha o te oumu me te puna rewa.
Pereki Toromitī
He kōwhiringa ōhanga, he kōwhiringa whai hua hoki ngā pereki dolomite mō ngā wāhi he āhua ngawari te āhua o te mahi, pērā i te raro o te oumu me te tinana o raro o te oumu. He mea hanga mai i ngā ranunga konupūmā kāponāte me te konupūmā kāponāte kua whakapūkarahia, he ātete pai ki te para kawakore, ā, he maha ngā wā ka whakamahia hei whakakapi utu-pai mō ngā pereki konupūmā parakore.
Ngā pereki dolomite kua herea ki te tara-bitumenhe tino pai mō ngā arai pumau, e whakarato ana i te whakamarumaru wera pono me te pumau o te hanganga.
Ngā Rauemi Ātete Mahi
He mea nui ngā rauemi ātete mahi mō ngā wāhanga matua o te kaitahuri.Ngā puru horoi (ngā pereki uruhanga)e whakamahia ana i roto i te pūnaha pupuhi-raro, e whakaatu ana i te hanganga waro ngongo-konupora whakarewa hei whakarite i te werohanga hau pumau i te wā e whakarewaina ana.
Ngā mea whakarewa ātete-kore korundum (te ihirangi Al₂O₃ ≥90%)e whakamahia ana ki ngā wāhi e kaha ana te kakahu pērā i ngā tauranga pato, e tuku ana i te ātete ki te pāmahana tino tiketike me te ātete kaha ki te waikura.
Paraikete muka uku me ngā rauemi whakatika
Paraikete muka ukuHe rauemi ātete-wera hoki ēnei e tino hiahiatia ana mō ngā kaitahuri, e whakamahia ana mō te whakamahana i te waha o te kaitahuri, te paipa hau, me ētahi atu wāhanga. He ngawari, he māmā hoki, he tino pai te ātete ki te pāmahana teitei me te mahi whakamahana, ka taea te whakaiti i te ngaronga wera, te whakaiti i te whakapaunga pūngao, me te whakamamae i te ahotea wera i puta mai i ngā huringa pāmahana ohorere o te tinana oumu hei tiaki i te hanganga oumu.
Ngā ranunga whakakī me ngā rauemi whakatikahe mea tino nui hoki, hei pupuri i te kounga o te arai me te whakaiti i te wā kore mahi i whakamaheretia.
Ko te whiriwhiri i ngā rauemi ātete-waikawa tika me whai i te mātāpono o"te whakarārangi rohe me te whakaritenga mahi", te whakataurite i ngā āhuatanga o te rauemi ki ngā āhuatanga mahi motuhake o ia rohe kaitahuri. Ehara i te mea ka roa ake te ora o te oumu i ngā rauemi ātete kounga teitei, engari ka whakaitihia hoki ngā utu whakahaere me te whakapai ake i te kounga maitai mā te ārai i te poke o te rauemi.
Mō ngā otinga rauemi ātete-hurihuri ritenga hei whakarei ake i te whai huatanga me te pakari, whakapā mai ki tā mātou tīma ngaio i tēnei rā.
