Whakaahuatanga:
He kohua uku te oko whakarewa e whakamahia ana hei pupuri i te konganuku hei whakarewa i roto i te oumu. He oko whakarewa kounga teitei tēnei, he kounga ahumahi e whakamahia ana e te umanga whakarewa arumoni.
Ngā Mahi a ia:
E hiahiatia ana he oko whakarewa hei tu atu i ngā pāmahana tino wera e pā ana ki te whakarewa o ngā konganuku. Me teitei ake te pāmahana rewa o te konganuku i tērā o te konganuku e whakarewahia ana, ā, me kaha tonu ahakoa te wera nui.
Ka taea te whakamahi i tētahi ipu rino hanga-kāinga hei whakarewa i ngā konganuku pēnei i te konutea me te konumohe, nā te mea he iti iho te pāmahana o ēnei konganuku i te pāmahana o te rino. Heoi, he raruraru te whakakorikori (te pakarukaru) o te mata o roto o te ipu rino. Ka taea e tēnei tauine te whakapoke i te rewa me te whakangawari wawe i ngā pakitara o te ipu. Ka pai ngā ipu rino mēnā kei te tīmata noa koe, ā, kāore he āwangawanga ki te mahi i te whakakorikori.
Ko ngā rauemi ātete-hau e whakamahia ana i roto i te hanganga oko ko te uku-karāpiti, me te silicon-carbide e herea ana ki te waro. Ka taea e ēnei rauemi te tu atu ki ngā pāmahana teitei rawa atu i roto i ngā mahi whakarewa noa. Ko te painga tāpiri o te silicon carbide he rauemi tino pakari.
Ko ā mātou oko whakarewa āhua uku karāpiti he mea whakatau mō te 2750 °F (1510 °C). Ka taea e rātou te whakamahi i te konutea, te konumohe, te parahi/parahi, te hiriwa me te koura. E ai ki te kaihanga ka taea te whakamahi mō te rino maka. I hangaia ki te Hononga o Amerika!
Ngā Āhua o te Para:
He rite te āhua o te oko waina ki te āhua o te oko waina ("āhua B"). Ko te rahinga "ko te ko te whānui o te oko waina i tōna pito whānui rawa. Mena kāore he whānui o te ko te whānui o te ko, ko te whānui o runga te whānui mōrahi.
E ai ki tētahi ture matua, ko te nama o te oko "bilge" e whakaatu ana i tōna kaha mahi tata ki ngā pauna o te konumohe. Mō te parahi, te parahi rānei, whakamahia kia toru ngā wā o te nama o te oko. Hei tauira, ka taea e te oko #10 te pupuri i te 10 pauna o te konumohe me te 30 pauna o te parahi.
Ko ā mātou oko whakarewa āhua "B" e whakamahia ana e ngā kaiwhaiwhai me ngā kaimahi whakarewa auau. He oko whakarewa kounga teitei, he roa te mau.
Tirohia ngā ripanga i raro nei kia kitea ai te rahi e tika ana mō tāu mahi.
Me pēhea te whakamahi:
Me whakamahi i ngā kokopi (taputapu hiki) e tika ana te whakamahi i ngā oko katoa. Mā ngā kokopi hē ka pakaru, ka pakaru rānei te oko i te wā tino kino rawa atu.
Ka taea te whakatakoto i tētahi kōpae kāri i waenganui i te para me te turanga oumu i mua i te whakamahana. Ka mura tēnei, ka waiho he paparanga waro i waenganui, ā, ka ārai i te piri o te para ki te raro o te oumu. Ka pērā anō te paninga o te Plumbago (Carbon Black).
He pai ake te whakamahi i tētahi oko rerekē mō ia momo konganuku hei karo i te poke. Me whakarite hoki kia tino ringihia te wai o te oko i muri i te whakamahinga. Ka taea e te konganuku e waiho ana kia totoka i roto i te oko te whakawhānui ina whakamahanahia anō, ā, ka whakangaro.
Whakamahanahia ngā oko hou, ngā oko rānei kua rongoatia. Whakamahanahia te oko kau mō ngā hāora e rua i te 220 F (104 C). (Whakamahia he hauhautanga tika. Ka paowa ngā oko hou i te wā e whakatō ana te wai whakakī.) Kātahi ka tahuna te oko kau kia whero te wera. Tukua kia whakamatao te oko ki te pāmahana rūma i roto i te oumu i mua i te whakamahinga. Me whai i tēnei tikanga mō NGĀ oko hou KATOA me ngā oko katoa kua pāngia pea e te haukū i te wā e rongoatia ana.
Rokirokihia ngā oko katoa ki te wāhi maroke. Ka taea e te makuku te pakaru o te oko i te wā e whakamahanahia ana. Mena kua roa e rongoatia ana, he pai ake te whakahou i te whakamahana.
Ko ngā oko whakarewa silicon carbide te momo tino iti te tūponotanga ka mimiti i te wai i te wā e rongoa ana, ā, kāore e hiahiatia kia whakamahanatia i mua i te whakamahinga. He mea pai kia tahuna he oko whakarewa hou ki te wera whero i mua i tōna whakamahinga tuatahi hei pei atu me te whakapakeke i ngā paninga me ngā here o te wheketere.
Me tino koretake te whakatakoto i te rauemi ki roto i te ipu para. KAUA rawa e "tākai" i tētahi ipu para, nā te mea ka whānui te rauemi i te whakamahanatanga, ā, ka pakaru pea te uku. Kia rewa tēnei rauemi hei "rekereke", āta utaina atu ētahi atu rauemi ki roto i te puna wai hei rewa. (WHAKATŪPATO: Ki te mea he makuku kei runga i te rauemi hou, ka puta he PĀHŪ mamaoa). Kaua e tākai pūmau ki roto i te konganuku. Me whāngai tonu te rauemi ki roto i te rewa kia rewa rā anō te nui e hiahiatia ana.
WHAKATŪPATO!!!: He mea morearea ngā oko whakarewa. He mea morearea te whakarewa i te konganuku i roto i te oko whakarewa. He mea morearea te ringihia o te konganuku ki roto i ngā pokepokea. Tērā pea ka pakaru te oko whakarewa me te kore whakatūpato. Tērā pea kei roto i ngā oko whakarewa ngā hapa huna i roto i ngā rauemi me te hangahanga, ka arahi pea ki te pakaru, te kino o ngā taonga, te whara o te tangata, te whara o te hunga e tū tata ana, me te mate o te tangata.
Poraka Tūāpapa Para
Whakaahuatanga:
BCS He turanga pāmahana teitei te poraka turanga e whakamahia ana hei whakaara i te para ki te rohe wera o te oumu.
Ngā Mahi a ia:
Ko te tikanga, ka whakamahia te poraka turanga i roto i te oumu whakarewa hau hei hiki ake i te oko kia kore ai te mura o te mura e pa tika ki te pakitara angiangi o te oko. Mēnā ka tukua te mura o te mura kia pā tika ki te oko, ka pakaru pea te pakitara o te oko, ā, ka poto ake tōna ora. Ko te huarahi tika hei ārai i tēnei ko te whakamahi i te poraka turanga hei hiki ake i te oko i waho o te rohe mura.
Mā te hiki ake i te para ka taea ai te noho ki te "rohe wera" o te oumu. Ahakoa ka uru te mura o te mura ki te tinana o te oumu i raro, ko te rohe wera rawa atu mai i waenganui ki runga. I tēnei rohe ka tino wera ngā pakitara o te oumu e te hau e rere ana. Mā te noho o ngā taha o te para ki tēnei rohe ka pai ake te wera mai i te rerenga hau e pōrearea ana, me te wera hoki o ngā pakitara o roto o te oumu e mura ana.
Me pēhea te whakamahi:
Me teitei te poraka turanga kia rite te mura o te mura ki te tihi o te poraka. Kāore he aha mena he teitei ake te tihi o te poraka i te putanga o te mura. Ko te mea kāore koe e hiahia kia pā te mura ki ngā taha angiangi o te oko. He pai anō hoki mena ka pā te mura ki te wāhanga matotoru o raro o te oko, nā te mea kāore tēnei wāhanga e ngāwari ki te pakaru mai i te hau.
Ko Shandong Zhongpeng Special Ceramics Co., Ltd tētahi o ngā otinga rauemi hou uku silicon carbide nui rawa atu i Haina. Uku hangarau SiC: Ko te pakeke o Moh he 9 (ko te pakeke o Moh hou he 13), he ātete pai ki te horo me te waikura, he ātete pai ki te pakū me te ārai-waikura. Ko te roa o te ora ratonga o te hua SiC he 4 ki te 5 ngā wā roa atu i te rauemi alumina 92%. Ko te MOR o RBSiC he 5 ki te 7 ngā wā i tō SNBSC, ka taea te whakamahi mō ngā āhua uaua ake. He tere te tukanga whakatau utu, ko te tuku e rite ana ki te mea i oatitia, ā, ko te kounga kāore he rite. Ka tohe tonu mātou ki te wero i ā mātou whāinga me te tuku i ō mātou ngākau ki te hapori.
