I te ao o te hiki i runga i te papa, kāore he wāhi mō te hapa. Ehara i te mea he rauemi noa te kawenga e iri ana; he tūponotanga kino pea. Koia te take he aha te kounga o te mekameka hiki—ahakoaTau 80 (G80)te kukū teitei ake rāneiTau 100 (G100)—kāore e taea te whakanui rawa. Ki ngā miihini me ngā tohunga taura, he taputapu haumaru te mekameka, ā, me pupuri tōna tukanga hanga ki ngā paerewa tino tika.
I SCIC (www.scic-chain.com), e mārama ana mātou ko te pakari o te mekameka hiki ko te tapeke o ōna wāhanga. Mai i te matū o te maitai mata ki te paninga mata whakamutunga, ko ia taahiraa o te raina whakaputa ka whakatau i te kaha o te mekameka ki te mahi haumaru i raro i te kawenga.
Anei ngā āhuatanga matua e tautuhi ana i te kounga o te mekameka hiki o te ao.
1. Te Tūāpapa: Te Kōwhiringa Rauemi Rino
Kāore te haerenga ki tētahi mekameka hiki haumaru e tīmata i te wheketere, engari i te mira maitai. Me whakamahi ngā mekameka G80 me G100 i ngā maitai koranu motuhake—ko te nuinga o te wā kei roto ngā huānga pēnei i te chromium, te molybdenum, me te boron.
- Ngā Mekameka G80:Me whai maitai pai te hanganga, he iti te koranu, e aro ana ki te maimoatanga wera, hei tauira, 20Mn2, 22MnCrNi rānei.
- Ngā Mekameka G100:Me tono kia matatau ake te mahi whakarewa. Hei whakatutuki i te kaha kume teitei ake (1000 N/mm²) me te kore e pakarukaru, me ma ake te maitai (me te iti ake o ngā whakaurunga kore-whakarewa) me te tino tika o te whakarewa, hei tauira, SAE8620D.
Ko te whakamahi i te maitai iti iho i te paerewa hei penapena utu he huarahi tēnei mō te pakarukaru nui, te pakarukaru rānei.
2. Te Hononga Whakarewa: Te Hononga Kaha Rawa
Ko te kaha o te mekameka he rite ki tōna pūwāhi ngoikore, ā, mō ngā mekameka hononga porowhita, ko taua pūwāhi te hononga whakarewa. Ka whakamahia e ngā mekameka hiki hou te hononga whakarewa tere.
- Mana Tukanga: Me tino whakahaere te ia whakarewa, te pēhanga hurihanga, me te pāmahana kia kore ai e rerekē te whakarewa mai i te rauemi matua.
- Te ōritetanga: Me noho kore he waikura me ngā kapiti i te rohe whakarewa. I SCIC, ka whakarite mātou kia tangohia ma te mārama te uira whakarewa, engari ko te mea nui ake, kia mau tonu te hanganga o te maitai puta noa i te hononga.
3. Te Ngākau o te Mahi: Te Maimoatanga Wera
Mā te maimoatanga wera ka huri te wahi maitai piko hei wahi maitai mahi teiteiHe mekameka karaehe 80, 100 rānei.He tukanga tēnei e toru ngā wāhanga:
- Te whakapakeketanga: Ka whakamahanahia te mekameka ki tētahi pāmahana tino nui, kātahi ka tineia (ka tere te whakamatao) hei hanga i tētahi hanganga martensitic—te pūtake o tōna kaha nui.
- Te Whakamahana: Koinei te taahiraa tino mārō. Ka whakamahanahia anō te mekameka ki tētahi pāmahana iti iho. Mā tēnei ka whakaitihia ngā ahotea o roto mai i te tineia, ka "whakamahana" i te maitai, ka whakawhiti i tētahi paku mārō mō tētahi pikinga nui o te pakari. Ka totoro (ka roa) te mekameka kua whakamahanatia tika i mua i te whati, ka whakarato i tētahi whakatūpato e kitea ana i mua i te pakaru.
4. Manatoko: Whakamātautau Kaha me te Whati
Kāore e taea te tirotiro i te kounga o tētahi mekameka; me whakamatau koe. Me tutuki i ia mita o te mekameka hiki e hangaia ana ngā paerewa o te ao (pēnei i te ISO, i te DIN rānei).
- Whakamātautau Kaha Whakamātautau: Ka tukuna he kawenga whakamātautau ki ia mekameka (ko te tikanga he 2.5 ngā wā o te rohe kawenga mahi mō te G80). Mā tēnei ka totoro te mekameka kia ngāwari, hei manatoko i te pono o te rauemi me ngā whakarewa.
- Whakamātautau Kaha Pakaru: Ka toia ngā tauira whakangaro mai i ia puranga whakaputa ki te whakangaromanga. Me nui ake te kaha pakaru i te iti rawa kua tohua e te paerewa (hei tauira, 4 ngā wā o te WLL). Ehara i te mea ko te pa ki tētahi tau anake tēnei; engari ko te whakarite kia ngāwari te aratau rahunga (e whakaatu ana i te "nekehanga ki raro" o te hononga) kaua ki te pakarukaru.
5. Whakaotinga Mata: Te Tiaki me te Mahi
Ko te mahi whakamutunga ko te tiaki. Ko te taiao te mea e whakatau ana i te mutunga:
- Waikura Pango / Hinuhia: Ko te whakaotinga paerewa. Ka whakarato i te taumata turanga o te ātete waikura mō te whakamahinga o roto, ā, ka taea te tirotiro ngāwari i te mekameka mō ngā pakaru.
- Te peita (hei tauira, Te Whakatakotoranga Tae o te Tauira): He maha ngā wā e whakamahia ana hei tautuhi (hei tauira,He pango te nuinga o te wā i te G80, He kikorangi te nuinga o te wā o te G100). He ātete waikura taurite tōna.
- Te Whakarewa: He ātete pai ki te waikura mō ngā taiao moana, matū rānei. Heoi, me tino tupato tēnei. Ki te kore e tika te mahi (hei tauira, te whakapūkara waikawa), ka taea e te whakarewa te whakapūkara te whakakōpiri i te hauwai, ka pakarukaru ai te mekameka kaha-teitei. Me whai tukanga motuhake i muri i te tunu. Mō te whakaoti whakarewa wera, me whakaiti te rohe kawenga mahi me te kaha pakaru o te mekameka mā te 20-25%.
- Paninga-E (Whakatakotoranga Hiko): He kōwhiringa rongonui haere mō ngā mekameka G100. Ka whakaratohia he paninga tino ōrite, he pakari, ā, he ātete ki te waikura, me te kore e mōrearea te pakarukaru hauwai e pā ana ki te whakapūmau wera-tuku.
Ki te tohunga whakapūmau taura, he taputapu whakawhirinaki te mekameka. I SCIC, e whakapono ana mātou ka whiwhi whakawhirinaki mā te aro nui ki ia wāhanga o te hanga: te maitai, te whakarewa, te whakamahana, me te whakamātautau. Ina whiriwhiria e koe he mekameka G80, G100 rānei mai i SCIC (www.scic-chain.com), kei te whiriwhiri koe i tētahi hua i hangaia mō te haumaru, te pono, me te mahi i raro i ngā āhuatanga tino uaua.
