Ngā Take me ngā Otinga mō te Rahunga o te Moutere Pēhi Waipēhi

Ko te nuinga o tēnei tuhinga e whakamārama ana i ngā take mō te korenga opēhi waipēhingā pokepokea ai me ngā otinga.

1. Rauemi pokepokea ai

Nō te maitai whakarewa te maitai pokepokea ai. He hapa anō hoki pērā i ngā whakaurunga kore-whakarewa, te wehenga carbide, ngā pūwero waenga me ngā ira mā i roto i tōna hanganga, e tino whakaiti ana i te kaha, te pakari me te ātete ki te ngenge wera o te pokepokea ai. I te nuinga o te wā, ka wehea kia rite ki te kounga ki ngā pokepokea ai noa me ngā pokepokea ai kounga teitei. Nā te hangarau whakaputa matatau, he parakore te kounga o ngā pokepokea ai kounga teitei, he ōrite te hanganga, he iti te wehenga, ā, he pakari me te mahi ngenge wera teitei.

Otinga: Te hanga i ngā pokepokea noa hei wawahi i ngā whakaurunga kore-whakarewa nui, hei whakakore i te wehenga carbide, hei whakapai ake i ngā carbide, hei hanga i te hanganga kia ōrite hei whakatutuki i te pānga o ngā pokepokea kounga teitei.

2. Te hoahoa o ngā pokepokea ai

I te hoahoa o te pokepokea ai, me whakatau ngā āhuatanga o waho o te kōwae kia rite ki te rauemi me ngā āhuatanga āhuahanga o te wāhanga kua hangaia hei whakarite i te kaha o te pokepokea ai. Hei tāpiri, i te wā e whakamahanahia ana, e whakamahia ana hoki te pokepokea ai, nā te iti o te porowhita o te miro, te whānui o te pakitara angiangi, te rerekētanga nui o te matotoru o te pakitara, me te kore e tika te tūnga o te kōhao me te mokowā, ka ngāwari te nui o te kukū o te ahotea me te tīmatanga o te pakaru. Me karo te hoahoa pokepokea ai i ngā kokonga koi i ngā wā katoa e taea ana, ā, me whakarite tika ngā tūnga o te kōhao me te mokowā.

3. Tukanga hanga

1) Tukanga hanga

He maha ngā huānga koranu kei roto i te pokepokea ai, he nui te ātete ki te whakarerekētanga i te wā e hanga ana, he ngoikore te kawe wera, ā, he iti te pāmahana eutectic. Ki te kore koe e aro, ka pakaru te pokepokea ai. Me whakamahana ki te 800-900℃, kātahi ka whakamahana ki te 1065-1175℃. Hei tango i ngā whakaurunga nui kore-whakarewa, hei whakakore i te wehenga carbide, me te whakapai ake i ngā carbide, me mahi anō te hurihanga me te kukume i te wā e hanga ana me te whakaritenga ōrite. I te wā e whakamatao ana i muri i te hanga, ka puta he kapiti tinei. He ngāwari ki te whakaputa kapiti whakawhiti i waenganui. He puhoi te whakamatao i muri i tete hangaka taea te karo i tēnei raruraru.

2) Te tapahi

He nui te pānga o te taratara o te mata o te tukanga tapahi ki te mahi ngenge wera o te pokepokea ai. He iti te taratara o te mata o te kōhao pokepokea ai, ā, kāore he hapa pēnei i ngā tohu maripi, ngā karawarawa, me ngā kohao, ka hua ai te kukū o te ahotea me te pakaru o te ngenge wera.
Otinga: I te wā e tukatuka ana i te pokepokea ai, āraia ngā tohu maripi kei mahue i te porowhita o ngā kokonga o ngā wāhanga uaua. Ā, hurihia ngā kōhao, ngā taha awaawa me ngā pakiaka.

3) Te Hurihuri

I te wā e huri ana, ka taea e te wera waku ā-rohe te whakaputa i ngā hapa pēnei i te wera me te pakaru, ā, ka puta he ahotea kume toenga ki runga i te mata huri, ka arahi ki te pakaru wawe o te pokepokea ai. Ka taea e ngā wera i puta mai i te wera huri te whakamahana i te mata pokepokea ai kia puta rā anō te martensite kua whakamahanatia. Ka tino whakaitihia e te paparanga martensite pakarukaru me te kore e whakamahanatia te mahi ngenge wera o te pokepokea ai. Ina neke atu te pāmahana ā-rohe o te mata huri i te 800℃, ā, kāore i te rawaka te whakamatao, ka whakahoutia te rauemi mata ki te austenit ka tinei hei martensite. Ka nui ake te ahotea hanganga o te mata pokepokea ai. Ka puta he ahotea wera i te wā e huri ana te pāmahana o te mata pokepokea ai, ā, ko te taupatupatu o te ahotea hanganga me te wera ka taea te whakaputa i ngā pakaru huri i roto i te pokepokea ai.

4) Te mīhini hikohiko

He tikanga whakaoti tino nui te mīhini hiko-pāka i roto i te tukanga hanga pokepokea hou. Ina puta te mura, ka neke ake te pāmahana ohorere o te rohe i te 1000℃, nō reira ka rewa te konganuku i te pūwāhi tuku, ka mimiti. He paparanga angiangi o te konganuku rewa me te pakari anō kei runga i te mata o te mīhini hiko-pāka. He maha ngā kapiti moroiti kei roto. He mā kanapa tēnei paparanga angiangi o te konganuku. I raro i te taumaha o te pokepokea, ka ngāwari te whanake o ēnei kapiti moroiti hei kapiti nui, ka hua ake te pakaru wawe me te kakahu o te pokepokea.
Otinga: I muri i ngā tukanga EDM, ka whakamahanatia te pokepokea ai hei whakakore i te ahotea o roto. Heoi, kaua te pāmahana whakamahana e neke ake i te pāmahana whakamahana mōrahi i mua i te EDM.

5) Te tukanga maimoatanga wera

Mā te tukanga whakamahana tika ka taea e te pokepokea ai te whiwhi i ngā āhuatanga miihini e hiahiatia ana, me te whakapai ake i tōna roa mahi. Mēnā he hē te hoahoa, te whakahaere rānei o te tukanga whakamahana, ā, ka pakaru te pokepokea ai, ka kino rawa te kaha o te pokepokea ai, ka pakaru wawe, ka whakapoto hoki i te roa mahi. Ko ngā hapa o te whakamahana ko te wera nui, te wera nui, te tango waro, te pakaru, te paparanga whakapakeke kore taurite, te kore e ranea te pakeke, me ētahi atu. I muri i te whakamahinga mō tētahi wā, ina tae te ahotea o roto kua kohia ki te taumata morearea, me mahi te whakaiti i te ahotea me te whakatikatika. Ki te kore, ka pakaru te pokepokea ai nā te ahotea o roto ina whakamahia tonutia.

4. Te whakamahinga o ngā pokepokea ai

1) Te whakamahana i ngā pokepokea ai

He nui te ihirangi o ngā huānga koranu i roto i te pokepokea ai, ā, he iti te kawe wera. Me whakamahana katoa i mua i te mahi. Ki te tino teitei te pāmahana o te pokepokea ai i te wā e whakamahia ana, ka heke te kaha, ā, ka ngāwari te hurihanga kirihou, ka hinga te mata o te pokepokea ai. Ki te tino iti te pāmahana whakamahana, ka tino rerekē te pāmahana o te mata ina tīmata te whakamahi i te pokepokea ai, ka nui te ahotea wera, ā, ka ngāwari te pakaru.
Otinga: Ko te pāmahana whakamahana o te pokepokea ai ka whakatauhia kia 250-300℃. Ehara i te mea ka taea anake te whakaiti i te rerekētanga pāmahana o te hanga mate, me te karo i te ahotea wera nui i runga i te mata o te pokepokea ai, engari ka whai hua hoki te whakaiti i te āhua kirihou i runga i te mata o te pokepokea ai.

2) Te whakamatao me te whakahinuhinu i te pokepokea ai

Hei whakaiti i te wera o te pokepokea ai, hei karo hoki i ngā pāmahana tiketike, ka akiakihia te pokepokea ai kia whakamatao i te wā e mahi ana i te pokepokea ai. Mā te whakamahana me te whakamatao i ia wā o te pokepokea ai ka pakaru te ngenge wera. Me whakamatao mārire te pokepokea ai i muri i te whakamahinga; ki te kore, ka puta he ahotea wera, ka pakaru te pokepokea ai, ka pakaru.
Otinga: Ina mahi te pokepokea ai, ka taea te whakamahi i te karāpiti wai-wai me te 12% te ihirangi karāpiti hei whakahinuhinu hei whakaiti i te kaha hanga, hei whakarite i te rere noa o te konganuku i roto i te kōhao, hei whakangawari hoki i te tukunga o te hanga. He pānga whakamarara wera anō hoki tō te whakahinuhinu karāpiti, ka taea te whakaiti i te pāmahana mahi o te pokepokea ai.

Ko ngā take me ngā otinga katoa mō te rahunga o te pokepokea aipa waipēhi kua whakahuatia i runga ake nei.Zhengxihe kaihanga e tohunga ana kitaputapu pēhi waipēhiMena he mea āu e hiahia ana, tēnā whakapā mai ki a mātou.
