Ngā Whakamahinga Matua o te Ranunga Whakaranu Kōrunuma puta noa i ngā Ahumahi
1. Ahumahi Whakarewa:Te Tuarā o te Whakarewa i te Pāmahana Teitei
Ko te rāngai whakarewa te mara tono nui rawa atu o te ranunga whakarewa korundum, inā koa i roto i te hanga maitai, te whakarewa konganuku kore-ferrous, me te hanga ferroalloy.
Ngā Taputapu Hanga Rino:He whānuitia te whakamahinga mō te whakapuru me te whakatika i ngā raro o te oumu hiko, ngā raro koko, ngā paparanga mahi tundish, me ngā poka tā. Nā te matotoru o te rauemi me te ātete kaha ki te horo, ka taea e ia te tu atu i te horoinga o te maitai rewa me te para, ka ārai i te urunga o te maitai rewa, ā, ka roa ake te ora o ngā taputapu whakarewa mā te 30%-50% ki te whakataurite ki ngā taputapu whakarewa tikanga.
Te Whakarewatanga o te Konganuku Kore-Wero:I roto i ngā mīhini whakarewa konumohe, parahi, konutea, me ētahi atu mīhini whakarewa kore-ferrous, ka pania te ranunga whakakī kōrunuma ki ngā arai o ngā oumu pupuhi, ngā oumu whakakoi, me ngā pūtau hikohiko. Ka urutau tōna pumau wera pai ki ngā huringa pāmahana auau i te wā whakarewa, ā, ko tōna ātete ki te waikura matū mai i ngā konganuku rewa me ngā rerenga ka whakarite i te parakore o te hua whakamutunga.
Te Hanganga Ferroalloy:Mō ngā oumu whakarewa ferrochrome, ferromanganese, me ētahi atu oumu whakarewa ferroalloy, ka taea e te ātete pāmahana teitei o te rauemi (tae atu ki te 1800℃) me te ātete kakahu te tu atu i te taiao mahi uaua o ngā tauhohenga whakaiti pāmahana teitei, ka whakaiti i te wā kore mahi tiaki oumu.
2. Te Ahumahi Rauemi Hanga: Te Whakapūmau i te Pūmautanga o ngā Mahi Oiln
I roto i te umanga rauemi hanga whare, he mea nui te ranunga korundum mō ngā oumu hanga sima, karāhe, me te uku, ina hoki ka pāngia e te pāmahana teitei me te pirau rauemi mō te wā roa.
Ngā oumu sima:E whakamahia ana mō te whakarārangi i te rohe whakawhiti, te rohe tahu, me te awa hau tuatoru o ngā oumu hurihuri sima. Mā te ātete kaha o te rauemi ki te horo kawakore me te ru wera ka taea te ātete i te waikura o te sima kinker me ngā konganuku kawakore, ka whakaiti i te kiri o te oumu, ka whakaroa hoki i te huringa mahi o te oumu.
Ngā oumu karāhe:Mō ngā oumu whakarewa karāhe, ka pania te ranunga whakakī kōrunuma ki raro, ki ngā pakitara taha, me ngā wāhanga korokoro. Ko tōna matotoru me te iti o te porosity ka ārai i te urunga me te mimiti o te wai karāhe, ka whakarite i te mārama me te kounga o ngā hua karāhe, me te whakaiti hoki i te whakapaunga pūngao nā te mea he pai te mahi whakamahana.
Ngā oumu uku:I roto i ngā oumu whakarewa uku pāmahana-tiketike, mā te kakano ōrite o te rauemi me te mahi pāmahana-tiketike pumau ka whakarite kia ōrite te tohatoha pāmahana oumu, ka whakapai ake i te kounga whakarewa o ngā uku me te whakaiti i ngā reiti hapa hua.
3. Ahumahi Matū: Te Ātete i te Waikura i roto i ngā Taiao Kino
He maha ngā wā ka uru atu ngā tauhohenga pāpāho pāmahana teitei, pēhanga teitei, me te waikura ki roto i te umanga matū, ā, he mea tino pai te ranunga whakakī kōrunuma hei rauemi ātete ahi mō ngā tauhohenga, ngā oumu, me ngā paipa.
Ngā Tauhohenga Matū:Mō ngā tauhohenga hauwai, ngā oumu pakaru, me ētahi atu taputapu, mā te ātete o te ranunga korundum ki te waikura waikawa, kawakore, me te waikura whakarewa waro ka whakarite i te haumaru me te pumau o ngā tauhohenga matū, ka karo i te turuturu o ngā taputapu i puta mai i te pakaru o te ātete.
Ngā Oumu Hinu:I roto i ngā oumu whakahinuhinu hinu me ngā oumu pakaru matū, ka taea e te ātete pāmahana teitei me te ātete kakahu o te rauemi te tu atu i te horoinga o te hinu me te hau pāmahana teitei, ka roa ake te ora o ngā ngongo oumu me te whakaiti i ngā utu tiaki.
Ngā Ouma Tahunga Para:Mō ngā oumu tahunga para kino me ngā oumu tahunga para totoka ā-tāone, ko te ātete o te ranunga korundum ki te waikura pāmahana teitei me te memeha o te pungarehu ka ārai i te kino o te tinana oumu, ka whakarite kia mahi tonu ngā taputapu tahunga me te tutuki i ngā paerewa tukunga tiaki taiao.
4. Ētahi atu Whakamahinga Hou: Te Whanui ki ngā Marae Pāmahana-Tiketike Hou
I te whanaketanga o te hangarau ahumahi pāmahana-tiketike, kei te whānui haere te ranunga korundum ki ngā mara hou pēnei i te pūngao hou, te rererangi, me te mana wera.
Te Ahumahi Pūngao Hou:I roto i ngā pūnaha whakaputa hiko wera o te rā, ka whakamahia hei whakapuru i ngā tāke rokiroki wera pāmahana teitei me ngā whakawhiti wera, ka whakamahi i tōna pumau wera me te mahi rokiroki wera pai rawa atu hei whakapai ake i te pai o te hurihanga pūngao.
Te Ahumahi Rererangi:Mō ngā tūnga whakamātautau miihini rōkete me ngā taputapu tukatuka wāhanga pāmahana-tiketike, ko te ātete pāmahana tino-tiketike o te rauemi (tae atu ki te 2000℃ i te wā poto) me te kaha miihini e tutuki ana i ngā whakaritenga taiao tino nui o te hanga rererangi.
Ngā Whare Hiko Wera:I roto i ngā poiha hiko waro me te hau, ka whakamahia te ranunga whakakī kōrunuma ki te rūma mura me ngā arai o te paipa, ka whakaiti i te kakahu me te waikura o ngā poiha, ā, ka whakapai ake i te whai huatanga me te haumaru o ngā taputapu whakaputa hiko.
