I te ao o te mahi whakarewa ahumahi, e mōhiotia ana te maitai kore waikura mō tōna "pakari" tino nui. Ahakoa kei te mahi koe me te 304, 316, ngā koranu motuhake rānei o te raupapa 400, ka hangaia e ēnei rauemi he wero nui mō ngā taputapu tapahi paerewa: te wera nui, te wera ā-rohe.
I Jiacheng Tools, he maha ngā wā ka whakamāramahia e tā mātou tīma hangarau he aha i pakaru wawe ai ngā mata o te maitai tere-teitei (HSS) paerewa i te wā e keri ana i te maitai kore waikura. Kei roto i ngā āhuatanga wera o te rauemi te whakautu, ā, ko te otinga tino pono ko te whakamahi i ngā mata o te kobalt (HSS-Co).
Te Pūtaiao o te Wera i roto i te Kowiri tira
He iti rawa te kawe wera o te maitai kore waikura. Ina kerihia, kāore te wera e puta mai ana i te mahi tapahi e memeha haere ana i roto i te mea mahi, e mawhiti atu rānei me ngā maramara. Engari, ka noho pūmau te wera ki te wāhi e tūtaki ai te mata keri ki te konganuku.
I te nuinga o te wā ka tīmata te whakangawari me te ngaro o te koi o ngā mata tapahi o ngā mata HSS paerewa ina tae te pāmahana ki te 500°C. I te memeha haere o te mata, ka tīmata te mirimiri, kaua ki te tapahi, ka nui ake te waku me te wera. Ka tere te arahi o tēnei ki te pito "wera", ki te mata wiri pakaru, me te wahi mahi pakaru.
Te mea ngaro o te "pakari whero"
He mea hanga ngā mata wiri kobalt—inā koa ko ērā i hangaia mai i ngā koranu M35 (5% Kobalt) M42 rānei (8% Kobalt)—kia ora ai i roto i ēnei taiao pāmahana teitei.
Ko te painga hangarau tino nui o Cobalt ko te "Pakeke Whero." Koinei te kaha o te taputapu tapahi ki te pupuri i tōna hanganga me tōna mata koi ahakoa kei te mura te taputapu (tae atu ki te 600°C - 700°C). Ahakoa ka whakangawari (ka ngawari) te maitai paerewa i ēnei taumata, ka noho pakari tonu ngā koranu Cobalt, ā, ka haere tonu te tapahi ma.
M35 vs M42: Ko tēhea te mea e hiahiatia ana e koe?
Hei whiriwhiri i te taputapu tika mō tō kaupapa, he mea āwhina kia mārama ki ngā momo matua e rua e whakamahia ana i roto i te hanga ngaio:
●M35 (5% Kobalt): Koinei te "tino pai" mō te maitai kore waikura. He pai te taurite o te ātete wera me te pakari, ā, he iti ake te pakarukaru i ngā taumata kobalt teitei ake. Koinei te whiringa pai mō te nuinga o ngā mahi tiaki me te whakaputa ahumahi.
●M42 (8% Cobalt): I hangaia mō ngā rauemi tino uaua pērā i te Titanium, i te Inconel rānei. Ahakoa he pakeke ake tōna whero, he pakarukaru ake i te M35. Me whakamahi mīhini pumau, tino tika hoki kia kore ai e pakaru i raro i te pēhanga taha.
He pēhea te āwhina a Cobalt? (Te Painga Matatini)
Tērā pea koe e whakaaro ana: he aha te nui o te rerekētanga o te mahi mā te tāpiri i tētahi ōrau iti o te Cobalt (5%, 8 rānei%)? Kei roto i te hanganga ngota o te maitai taputapu te mea ngaro.
1. Te Whakaara i te Pāmahana Whakamātao Tino Hira
I roto i te HSS paerewa, ko te pakeketanga i ahu mai i ngā warowaiha matatini. Heoi, ina neke atu te wera i te 500°C, ka tīmata ēnei warowaiha ki te rewa, ki te "pakaru" rānei, ka ngaro te kaha o te maitai, ka ngawari. Ko te Cobalt he "whakaū". Ka whakanui ake i te pāmahana e tīmata ai te ngawari o te maitai, kia mau tonu ai te pakari o te mata tapahi ahakoa i raro i te ahotea wera nui.
2. Te Whakapakari i te Matrix
Ka noho tonu a Cobalt i roto i te "wairewa totoka" o te anga rino. Kāore e hanga i ōna ake warowaiha; engari, ka whakapakari i te hononga i waenga i ētahi atu huānga pēnei i te Tungsten, te Molybdenum, me te Vanadium. Whakaarohia a Cobalt hei "piri" e pupuri ana i te hanganga tioata o te mata wiri ina ngana te wera ki te wehe.
3. Te Whakarei Ahu Wera i te Pito
He mea whakamīharo, ahakoa he ngoikore te maitai kore waikura, ka āwhina a Cobalt i te mata keri kia pai ake te whakahaere i te pūngao. Mā tēnei ka taea e te taputapu te pupuri i te ōwehenga wera-pakeke teitei ake, ko te tikanga he iti ake te rerekētanga i waenga i tōna pakeketanga pāmahana rūma me tōna pakeketanga wera-tiketike i tērā o te maitai paerewa.
3 Ngā Take i Kohuatia ai a Cobalt hei Kōwhiringa Ngaio
●Ātete ki te Whakapakari Mahi: Ka "pakari tonu" te mahi a te maitai kore waikura. Mēnā ka mutu, ka mirimiri rānei te mata o te wiri, ka uaua ake te wero i te mata. Ka mau tonu te mata koi o ngā mata kobalt e ngau tonu ana ki te rauemi, ā, ka ārai i te whakapakari o te mata.
●Te Ora Pai o ngā Utauta: I roto i te taiao whakaputa nui, ko te "utu" o tētahi taputapu kei roto ko te wā e pau ana ki te whakawhiti. He roa ake te ora o ngā mata kobalt i te HSS paerewa, arā, he iti ake ngā whakawhiti taputapu me te iti ake o te wā whakatā o te mīhini.
●Te Utu Whai Hua Tuturu: Ahakoa he 30% te utu nui ake o te mata kobalt i te mata paerewa, ka taea e ia te keri i te 5 ki te 10 ngā wā te nui ake o ngā kōhao i roto i te maitai kore waikura. Mā tēnei ka iti ake te utu mō ia kōhao, ka penapena moni mō tō pakihi i te wā roa.
Tohutohu a te Tohunga mō te Mahi Tino Pai
Hei whakanui ake i te roa o te ora o āu wiri Jiacheng Cobalt, whai i ēnei aratohu ngaio:
1. Whakaitihia te Tere (RPM): Ka tino whai hua te mahi a ngā moka Cobalt i ngā tere iti. Ka puta he wera koretake i te tere teitei, ā, kāore e taea e Cobalt te tu atu mō ake tonu atu.
2. Pēhanga Whāngai Pūmau: Kaua rawa e tukua te mata o te konganuku kia "noho" ki roto i te kōhao. Whakamahia he pēhanga pumau, pūmau hoki kia mōhio ai kei te tangohia tonutia te konganuku e ngā taha tapahi.
3. Whakamahia he hinu whakahinuhinu kounga teitei: Ahakoa ka ātete a Cobalt ki te wera, ka horoia ngā maramara e te hinu tapahi he whanariki, he wai whakamatao kounga teitei rānei, ā, ka roa ake te ora o te taputapu.
Whakamutunga
Mō ngā awheawhe, ngā wheketere rānei e mahi ana i te maitai kore waikura, ehara i te mea he taonga noa iho ngā mata keri Cobalt—he mea nui hoki. Mā te haumi ki te koranu tika, ka whakarite koe i te pono, te tika, me te whai huatanga i roto i ia kaupapa. I Jiacheng Tools, he tohunga mātou ki te whakarato i ngā otinga keri M35 me M42 kounga teitei hei pupuri i ō raina whakaputa kia haere tonu.
