1. Kupu Whakataki
E whakapau kaha ana a SCIC ki te whakarato i ngā rauemi kounga teiteimekameka keri hononga porowhitamō ngā tono keri waro roa. E mārama ana mātou ko ngā rahunga mekameka—ina puta mai—ehara i te mea ka whakararuraru noa i te whakaputanga engari ka puta hoki he tautohe arumoni, nā te mea he maha ngā wā ka tukuna e ngā kaiwhakamahi mutunga he utu ki te kaiwhakarato me te kore e tirotirohia katoatia ngā āhuatanga whakahaere o te papaanga. E whakamārama ana tēnei tono i te huarahi pūnaha a SCIC ki te rangahau rahunga mekameka, te whakahaere kereme, me te tātari take pūtake, i hangaia hei tiaki i ngā painga o ngā taha e rua me te pupuri i ngā whanaungatanga pakihi mo te wā roa.
2. Te Whakapūmau Kounga i mua i te Tukunga a te SCIC
Kei roto i ia puranga mekameka keri SCIC he tuhinga kounga whānui, tae atu ki:
- Ngā tiwhikete mira rauemi me te manatoko hanganga matū
- Ko ngā pūrongo tirotiro inenga e rite ana ki te DIN 22252, ki ngā paerewa rite rānei
- Ngā tiwhikete whakamātautau kawenga/kaha me ngā raraunga whakaroa i te kaha whakamātautau me te whakaroa katoa i te whati
- Ngā hua whakamātautau kōtaha mārō (Brinell, Vickers rānei)
- Ngā hua whakamātautau pānga Charpy e ine ana i te pakari o te pūwāhi whakarewa
- Ngā tuhinga tirotiro tirohanga
Mā ēnei tuhinga ka whakatūria te tūnga o SCIC, arā, ko ngā mekameka keri (tae atu ki ngā hononga mekameka) e wehe atu ana i tō mātou whare i runga i te tutuki katoa i ngā paerewa e tika ana.
3. Ngā Aratau Rahunga o te Mekameka Noa: Te Whakarōpūtanga Hangarau
3.1 Pakaru o te Ngenge (Te Tikanga Matua)
Ko te ngenge te tino take o te pakaru o ngā mekameka taraiwa e pāngia ana e te kawenga kume hurihuri. Ka tīmata ngā pakaru i ngā wāhi kukū ahotea—pērā i ngā pūwāhi whakapā i waenga i ngā hononga tata, i ngā poka waikura rānei—ā, ka horapa haere tonu kia puta rā anō te pakaru whakamutunga. Ko te tikanga ka puta ngā pakaru ngenge ina mahi te mekameka i raro iho i tōna kaha kume tūmau, e tohu ana ko ngā āhuatanga kawenga mahi, ehara i te korenga o ngā rauemi, te pūtake matua.
3.2 Te Rahunga i Āhuatia e te Kakahu
Ka puta te pakaru o te mekameka mā te nekehanga reti i waenga i ngā hononga i te wā e mau ana, e wetewete ana hoki te mekameka i ngā niho o te porotiti. Ko te ngaronga whakawhiti-wāhanga ka whakaiti i te kaha whai hua, ā, ka arahi ki te roa o te mekameka keri ki tua atu i ngā rohe e whakaaetia ana (te nuinga o te 3%), ka ngaro te hototahitanga o te porotiti mekameka, ā, ka kore e whakaaetia te tohatoha kawenga.
3.3 Te Utaina Nui me te Utaina Ru
Ko ngā pānga ohorere—ngā kaikawe kua piri, ngā wāhanga kua mau, ngā tīmatanga ohorere rānei—ka puta ngā whati taumaha kume e tohuhia ana e ngā ngutu kutikuti, ngā mata whati kapu-me-kone, me te āhua rerekē e kitea ana. Ko ngā whati taumaha ka puta wawe tonu, ā, ka haere tahi me te āhua rerekē kirihou e kitea ana e te kanohi tahanga.
3.4 Ngā Rahunga Āwhina-Waikura
Ko ngā āhuatanga o te wai o raro whenua—ina koa ko te wai tote nui, ko te wai maina waikawa rānei—ka tere ake te ngaronga o te konganuku whānui, ka puta he poka i te mata o ngā hononga mekameka e mahi ana hei wāhi tīmatanga mō te horapa o te kapiti ngenge. Ka taea e te kapiti waikura taumahatanga te whakaputa i ngā pakaru pakarukaru kino me te kore whakatūpato i mua.
4. Ngā Raru o te Whakahaere me te Tiaki i te Papa (Ngā Take Kāore e Rite ki ngā Ture)
E whakaū ana ngā rangahau ahumahi ko ngā rahunga e pā ana ki te mekameka te take o te 27% o te katoa o te wā kore mahi o te pakitara roa, ko te nuinga o ēnei rahunga e pā ana ki ngā mahi whakahaere hē i te papaanga, kaua ki ngā hapa hanga.
4.1 Te Taumahatanga Hē o te Mekameka (Pūtake Matua)
- Te kumekume rawa: Ka hua ake te kumekume nui rawa i te mekameka keri, ka tere ake te kume o ngā niho o te poroka. Ko te āhua noa o te ahumahi ko te kume rawa i ngā mekameka, ka tino whakaiti i te roa o te ora o te mekameka.
- Te ngoikore o te totoro (Ngāwari): Mā te ngoikore ka taea te whakapūpū i te mekameka keri, te peke ki runga i te pītau, me te nekeneke mai i te reihi kawe—kua tautuhia koinei te tino take o te kino ki ngā mekameka mata-kawe.
- Te kore taurite o te aho: Ko te kore o te taurite o te raina mata ka rerekē te āhua i waenga i ngā mekameka mata me ngā mekameka taha, ka hua ake he tauira kakahu kore taurite e tere piki haere ana, ā, kāore e taea te whakatika ina kua tau.
4.2 Te Kore-ōrite o te Sprocket me te Wāhanga
- Ka ngaro te tūnga pai o ngā kōtaha niho o te pītau kua pakaru, ka taea ai e ngā hononga mekameka te paheke ki ngā niho taraiwa, ā, ka tere ake te pakaru o te mekameka me te pītau.
- Ki te kore e whakakapia ngā pūtu hono-para e ngaro ana, ngā para kawe kua pakaru, ngā pae waru kua piko rānei, ka puta he āhuatanga uta koretake ka tere ake te pirau o te mekameka.
4.3 Te Whakahaere Whakahinuhinu me te Parahanga Kāore i te Rawaka
- Kāore i te rawaka, kāore rānei i te tika te whakahinuhinu (e taunakihia ana te whakamahi hinu lithium molybdenum disulfide mō ngā tono pēhanga teitei)
- Te urunga o te puehu me te paru ki roto i ngā hononga mekameka
- Te parahanga o te wai e arahi ana ki te waikura me te horoinga o te hinu whakahinuhinu
4.4 Ngā Tikanga Tāutanga me te Tiaki Hē
- Te korenga e manatoko i te tika o te whakapūmau i te wā tāutanga me ngā tirotiro auau
- Te tango i ngā hononga neke atu i te rua i te wā kotahi (he tohu tēnei he nui rawa te ngoikore) te tango rānei i ngā hononga e whā (te hanga i te whakapehapeha nui rawa atu)
- Kāore e whakakapi i ngā pae waruwaru piko, e whakatika rānei i ngā āputa mā te whakamahi i te mana taraiwa, kaua ki te whai i ngā tikanga tika
4.5 Ngā ngoikoretanga o te whakahaere kanohi
- He nui rawa te piko me te koretake o te taunga o te mata
- Kei tua atu i ngā rohe roa kua tūtohutia te mekameka e oma ana (neke atu i te 2-3% o te roa taketake)
- Te korenga e aroturuki me te pupuri i ngā rerekētanga kume i roto i te awhe 1-2 tana i tūtohutia i waenga i te taha mata me te taha gob
5. Te Tikanga Tirotiro me te Whakatau Kereme a SCIC
5.1 Urupare Tonu (Ngā Hāora 48 Tuatahi)
Ina whiwhi te SCIC i tētahi whakamōhiotanga mō te korenga o te mahi, ka mahi rātou i ēnei mahi:
- Whakaaetia te whiwhinga me te tono kia tiakina te mekameka pakaru, ngā pītau hononga, me ngā wāhanga e karapoti ana
- Tonoa ngā rātaka tiaki o te papaanga, ngā tuhinga taumahatanga, me ngā raraunga whakaputa e kapi ana i te wā i mua i te rahunga
- Tukuna he māngai hangarau (me whakarite rānei kia tangohia he kaitirotiro ā-rohe tuatoru) hei whakaahua me te tuhi i te wāhi i rahua ai
5.2 Te Rangahautanga Pūtake Ngātahi
Ka tīmatahia e SCIC tētahi rangahau hanganga whai muri i te tikanga tātari aituā kua whakatūria, tae atu ki:
- Te tirotiro ā-kanohi me te tirotiro whānui: Te āhua o te mata pakaru, ngā tauira whakarerekētanga, ngā tauira kakahu, ngā inenga roa, me te aromatawai waikura
- Te whakataurite ki ngā raraunga i mua i te tukunga: Ka arotakehia ngā tuhinga tohu katoa o roto hei whakaū i te tutuki o ngā whakaritenga i roto i te mekameka tukunga
- Arotake raraunga whakahaere: Ngā rangitaki taumahatanga o te papaanga, ngā tuhinga whakaputa, te hītori tiaki, me ngā pūkete aituā
- Tātari taiwhanga tuatoru (mēnā e hiahiatia ana): Tātari Fractographic mā te Scanning Electron Microscopy (SEM) hei wehewehe i waenga i te ngenge, te taumaha rawa, me ngā hapa i ahu mai i te hangahanga
5.3 Whakataunga e Hangai ana ki ngā Taunakitanga
I runga i ngā kitenga o te rangahau, ka whakarōpūtia e te SCIC te take o te rahunga hei tētahi o ēnei e whai ake nei:
| Whakataunga | Whakaahuatanga | Te Whakaaweawe Tauhokohoko |
| Hapa Hanga | Kua tautuhia te kore e tutuki i ngā whakaritenga kua whakamanahia | Ka whakaae a SCIC ki te kawenga; ka tukuna he whakakapinga, he nama rānei |
| Take Whakahaere o te Pae | Ko te korenga e pā ana ki te taumahatanga hē, te kore taunga, te kakahu, te poke, te mahi kua tuhia rānei ki te papaanga | Kei te kaiwhakamahi whakamutunga te kawenga; ka whakaratohia e SCIC he kōrero hangarau mō te aukati |
| Kāore i te mōhiotia | Kāore i te rawaka ngā taunakitanga hei whakatau i te take matua | Whakataunga tahi i runga i te ngākau pai arumoni me te whanaungatanga ā muri ake nei |
5.4 Ngā Mātāpono Whakatau Kereme
- Mārama: Ka tohaina ngā hua whakamātautau me ngā kitenga rangahau katoa ki te kiritaki
- Te mahi tahi hangarau: Ka whakaratohia e SCIC he kōrero hangarau kore utu mō ngā mahi whakatikatika ahakoa te whakataunga o te kawenga
- Ngāwari ki te hokohoko: Mō ngā kiritaki hou, mō ngā take tata rānei, ka taea e SCIC te tuku whakatikatika pai hei tiaki i ngā whanaungatanga me te pupuri tonu i ngā rohe kawenga mārama
6. Ngā Taunakitanga Ārai mō ngā Kaiwhakamahi Whakamutunga
Hei whakaiti i ngā hapa ā muri ake nei, hei whakanui ake hoki i te roa o te mahi a te mekameka, e taunaki ana a SCIC kia:
- Tāutahia he taputapu aroturuki i te kume o te mekameka i te wā tūturu (mēnā e wātea ana)
- Whakahaerehia ngā arowhai taumahatanga ia wiki, me te pupuri i ngā tuhinga
- Whakakapia ngā porotiti ina puta ngā tohu o te pakaru o te kōtaha niho
- Kia mau tonu te tūnga o te rārangi mata i roto i ngā whakaritenga
- Whakamahia ngā hinu whakahinuhinu e tika ana, me te pupuri tonu i te whakahaere poke
- Whakatūria, ā, whai i ngā wātaka tiaki kua whakaritea, tae atu ki te ine i te roanga o te hononga me te tirotiro i te āhua o te hononga.
7. Whakamutunga
Ko te tūnga o SCIC, me rapu rangahau pūnaha, e ahu mai ana i ngā taunakitanga mō ngā rahunga o te mekameka keri i mua i te tukunga o te kawenga. Mā tā mātou tuhinga tohu i mua i te tukunga ka whakatūria te hanganga o te mekameka, ko tā mātou tikanga rangahau rahunga ka wehewehe i waenga i ngā hapa hanga (e whakaae ana a SCIC ki te kawenga mōna) me ngā āhuatanga whakahaere o te papaanga (e noho tonu ana i raro i te mana o te kaiwhakahaere maina). Mā tēnei huarahi taurite, mārama hoki e tiaki ngā painga arumoni o ngā taha e rua, me te whakatairanga i ngā whanaungatanga kaiwhakarato-kiritaki mō te wā roa, e ahu mai ana i te whakawhirinaki.
