Te hanganga o te oumu kauhanga mowhiti me te kōwhiringa o te miro whakamahana wera
Ngā whakaritenga mō te hanganga o te tuanui oumu: me tu te rauemi i te pāmahana teitei mō te wā roa (ina koa ko te rohe tahu), kia māmā, kia pai te whakamarumaru wera, kia piri te hanganga, kia kore e turuturu te hau, ā, kia pai te tohatoha o te hau i roto i te oumu. Ko te tinana oumu kauhanga whānui kua wehea mai i mua ki muri ki te wāhanga whakamahana (wāhanga pāmahana iti), he wāhanga tahu me te tunu (mahana teitei me te poto), me te wāhanga whakamatao (wāhanga pāmahana iti), me te roa katoa o te 90m~130m. Ko te wāhanga pāmahana iti (tata ki te 650 nekehanga) e whakamahi ana i te momo noa 1050, ā, ko te wāhanga pāmahana teitei (1000~1200 nekehanga) e whakamahi ana i te momo paerewa 1260, 1350 zirconium konumohe rānei. Ka whakamahia ngātahitia te waeine muka uku me te paraikete muka uku hei hanga i te hanganga o te miro whakamarumaru wera oumu kauhanga mowhiti. Mā te whakamahi i ngā waeine muka uku me te hanganga hiato paraikete paparanga ka taea te whakaiti i te pāmahana o te pakitara o waho o te oumu me te whakaroa i te roa o te mahi o te arai pakitara oumu; I taua wā anō, ka taea hoki e ia te whakataurite i te koretake o te pereti maitai o te oumu, me te whakaiti i te utu o te arai miro whakamahana; hei tāpiri, ina pakaru te mata wera, ā, ka puta he āhuatanga ohorere, ka puta he āputa, ka taea hoki e te paparanga papatahi te tiaki i te pereti tinana oumu mō te wā poto.
Ngā painga o te whakamahi i te arai muka uku mō te miro whakamahana oumu kauhanga porowhita
1. He iti te matotoru o te arai muka uku: he mama ake i te 75% i te arai pereki whakamahana māmā, ā, he mama ake i te 90%~95% i te arai whakarewa māmā. Ka whakaitihia te kawenga hanganga maitai o te oumu, ka roa ake te ora o te oumu.
2. He iti te kaha wera (te rokiroki wera) o te arai muka uku: ko te kaha wera o te muka uku he tata ki te 1/10 noa iho o te arai ātete wera māmā me te arai whakarewa māmā. Ko te iti o te kaha wera he iti ake te mimiti o te wera i te oumu i te wā e mahi ana i te tauutuutu, ā, ka tere ake te tere o te whakamahana, ka whakaiti i te whakapaunga pūngao i roto i te whakahaere pāmahana oumu, inā koa mō te tīmatanga me te whakaweto o te oumu.
3. He iti te kawe wera o te arai muka uku: Ko te kawe wera o te arai muka uku he iti iho i te 0.1w/mk i te pāmahana toharite o te 400℃, he iti iho i te 0.15w/mk i te pāmahana toharite o te 600℃, ā, he iti iho i te 0.25w/mk i te pāmahana toharite o te 1000℃, arā, tata ki te 1/8 o ngā pereki uku mama me te 1/10 o ngā arai ātete wera mama.
4. He māmā te hanga me te whakahaere i te arai muka uku o te oumu. Ka whakapotohia te wā hanga o te oumu.
Ngā taahiraa tāutanga taipitopito o te miro whakamahana oumu kauhanga porowhita
(1)Te tango waikura: I mua i te hanganga, me tango e te rōpū hanganga maitai te waikura mai i te pereti parahi o te pakitara oumu kia tutuki ai ngā whakaritenga whakarewa.
(2)Tuhi Raina: E ai ki te tūranga whakaritenga o te waeine muka uku e whakaaturia ana i te tuhi hoahoa, whakatakotoria te rārangi ki runga i te pereti pakitara oumu, ka tohua te tūranga whakaritenga o ngā pūtu punga i te whakawhiti.
(3)Ngā pūtu whakarewa: E ai ki ngā whakaritenga hoahoa, whakarewahia ngā pūtu o te roa e rite ana ki te pakitara oumu e ai ki ngā whakaritenga whakarewa. Me mahi ngā mahi tiaki mō te wāhanga miro o ngā pūtu i te wā whakarewa. Kaua te paru whakarewa e tau ki runga i te wāhanga miro o ngā pūtu, ā, me whakarite kia pai te kounga o te whakarewa.
(4)Te Tāutanga o te Paraikete Papatahi: Whakatakotoria he paparanga paraikete muka, kātahi ka whakatakotoria te paparanga tuarua o te paraikete muka. Me whakarite kia kaua e iti iho i te 100mm te tawhiti o ngā hononga o te paparanga tuatahi me te tuarua o ngā paraikete. Hei whakangāwari i te hanganga, me whakapiri wā poto te tuanui oumu ki ngā kāri tere.
(5)Te tāutanga o te kōwae: a. Whakapiripirihia te ringaringa ārahi ki tōna tūranga. b. Whakahāngaihia te kōhao waenga o te kōwae ki te ngongo ārahi i runga i te pakitara oumu, panaia te kōwae kia poutū ki te pakitara oumu, ka pēhi piri te kōwae ki te pakitara oumu; kātahi ka whakamahia he kī ringaringa motuhake hei tuku i te nati i te ringaringa ārahi ki te pūtu, ka whakapiripiri i te nati. c. Tāutahia ētahi atu kōwae pēnei.
(6)Te Tāutanga o te Paraikete Whakautu: Ka whakaritea ngā kōwae ki te ahunga kotahi i te ahunga takai me te ahunga pēhi. Hei karo i ngā āputa i waenga i ngā kōwae i ngā rarangi rerekē nā te whakahekenga o te muka i muri i te whakamahana pāmahana teitei, me whakanoho ngā paraikete whakakapi o te taumata pāmahana kotahi ki te ahunga kore-whanui o ngā rarangi e rua o ngā kōwae hei whakaea i te whakahekenga o ngā kōwae. Ka whakapumautia te paraikete whakakapi pakitara oumu mā te whakaputa i te kōwae, ā, ka whakapumautia te paraikete whakakapi tuanui oumu ki ngā whao āhua-U.
(7)Whakatikatika arai: Kia oti te whakauru i te arai katoa, ka kutihia mai i runga ki raro.
(8)Te rehu i te mata o te arai: I muri i te tāutanga o te arai katoa, ka rehuhia he paparanga paninga mata ki te mata o te arai oumu (he kōwhiringa, ka taea te whakaroa i te roa o te mahi a te arai oumu).
