He kōrero anō mō te tā wera
1. Te Tā Wera me te Tā Matao
Ko te tā wera he tukanga hanga e mahia ana i muri i te whakamahanatanga o te pepa maitai, ko te tā matao ia e pā ana ki te tā tika o te pepa maitai me te kore e whakamahanatanga.
He mārama ngā painga o te tā matao i te tā wera. Heoi anō, he ngoikoretanga anō hoki. Nā te nui ake o ngā taumahatanga e puta mai ana i te tukanga tā matao ki te tā wera, he ngāwari ake te pakaru me te pakaru o ngā hua tā matao. Nō reira, me whai taputapu tā tika mō te tā matao.
Ko te tā wera he whakamahana i te pepa maitai ki ngā pāmahana teitei i mua i te tā, ā, i te wā kotahi ka tinei i roto i te mate. Mā tēnei ka huri katoa te hanganga moroiti o te maitai ki te martensite, ka hua ake he kaha teitei mai i te 1500 ki te 2000 MPa. Nō reira, he nui ake te kaha o ngā hua tā wera ki ērā atu hua tā makariri.
2. Te Rere o te Tukanga Taia Wera
Ko te tā wera, e mōhiotia ana ko te "pākeketanga pēhi," ko te whakamahana i tētahi pepa kaha-teitei me te kaha tīmatanga o te 500-600 MPa ki ngā pāmahana i waenga i te 880 me te 950°C. Kātahi ka tāia teretia te pepa wera, ka tineia ki roto i te mate, ka tutuki ai ngā tere whakamatao o te 20-300°C/s. Ko te whakawhiti o te austenite ki te martensite i te wā e tineia ana ka whakanui ake i te kaha o te wāhanga, ka taea ai te hanga i ngā wāhanga tā me te kaha tae atu ki te 1500 MPa. Ka taea te whakarōpū i ngā tikanga tā wera ki ngā wāhanga e rua: te tā wera tika me te tā wera ā-kore:
I roto i te tā wera tika, ka tukuna tika te mea parai kua whakamahanahia ki roto i te mata kua kati hei tā me te tinei. Ko ngā tukanga e whai ake nei ko te whakamatao, te kuti taha me te wero kōhao (te tapahi laser rānei), me te horoi mata.
Āhuatanga1: aratau tukatuka tā wera--tā wera tika
I roto i te tukanga tā wera ā-kore, ka mahia te taahiraa hanga-mua i mua i te tīmatanga o ngā wāhanga o te whakamahana, te tā wera, te kuti taha, te poka kōhao, me te horoi mata.
Ko te rerekētanga matua i waenga i te tā wera ā-kore me te tā wera tika kei roto i te whakaurunga o te taahiraa hanga-mua matao i mua i te whakamahana i roto i te tikanga ā-kore. I roto i te tā wera tika, ka whāngaihia tika te pepa whakarewa ki roto i te oumu whakamahana, i te tā wera ā-kore ia, ka tukuna te wāhanga kua hanga-mua matao ki roto i te oumu whakamahana.
Ko te rere o te tukanga o te tā wera ā-kore e whai ake nei:
Te hanga-mua i mua i te hanga--Te whakamahana-Te tā wera--Te kuti taha me te wero kōhao-Te horoi mata
Āhuatanga2: aratau tukatuka tā wera--tā wera ā-kore
3. Ko ngā taputapu matua mō te tā wera ko te oumu whakamahana, te mīhini hanga wera, me ngā pokepoke tā wera
Te oumu whakamahana:
Kei roto i te oumu whakamahana ngā āheinga whakamahana me te whakahaere pāmahana. Ka taea e ia te whakamahana i ngā pereti kaha-teitei ki te pāmahana whakakōkī anō i roto i tētahi wā kua whakaritea, kia tutuki ai he āhua austenitic. Me āhei ki te urutau ki ngā whakaritenga whakaputa tonu aunoa nui. Nā te mea ka taea anake te whakahaere i te pireti wera e ngā karetao, e ngā ringa mīhini rānei, me uta me te tango aunoa te oumu me te tika o te tūnga. Hei tāpiri, i te wā e whakamahana ana i ngā pereti maitai kāore i pania, me whakarato he tiaki hau hei ārai i te waikura o te mata me te tango waro o te pireti.
Pēhi Hanga Wera:
Ko te mīhini tā te uho o te hangarau tā wera. Me āhei ki te tā me te pupuri tere, me te pūnaha whakamatao tere hoki. Ko te uauatanga hangarau o ngā mīhini tā hanga wera he nui ake i ngā mīhini tā makariri tuku iho. I tēnei wā, he torutoru noa iho ngā kamupene o tāwāhi kua mōhio ki te hangarau hoahoa me te hanga o aua mīhini tā, ā, kei te whakawhirinaki katoa rātou ki ngā kawemai, ā, he nui te utu.
Ngā Pokepoke Wera:
Ka mahi ngā pokepokea wera i ngā wāhanga hanga me te tinei. I te wāhanga hanga, ina whāngaihia te pireti ki roto i te kōhao pokepokea, ka tere te whakaoti a te pokepokea i te tukanga tinei kia oti ai te hanganga wāhanga i mua i te whakawhiti i te rauemi ki te wāhanga martensitic. Kātahi ka uru ki te wāhanga tinei me te whakamatao, ka tukuna tonutia te wera mai i te mea mahi i roto i te pokepokea ki te pokepokea. Ka tangohia tonutia e ngā paipa whakamatao kua whakaritea i roto i te pokepokea te wera mā te wai whakamatao e rere ana. Ka tīmata te whakawhiti martensitic-austenitic ina heke te pāmahana o te mea mahi ki te 425°C. Ka mutu te whakawhiti i waenga i te martensite me te austenite ina tae te pāmahana ki te 280°C, ā, ka tangohia te mea mahi i te 200°C. Ko te mahi a te pupuri o te pokepokea he ārai i te whānui me te whakaheke wera kore taurite i te wā o te tukanga tinei, ka hua ake he huringa nui ki te āhua me ngā rahi o te wāhanga, ka hua ake he para. Hei tāpiri, ka whakarei ake i te pai o te whakawhiti wera i waenga i te mea mahi me te pokepokea, ka whakatairanga i te tinei tere me te whakamatao.
Hei whakarāpopototanga, ko ngā taputapu matua mō te tā wera ko te oumu whakamahana hei whakatutuki i te pāmahana e hiahiatia ana, he mīhini hanga wera hei tā tere me te pupuri me te pūnaha whakamatao tere, me ngā pokepoke tā wera e mahi ana i ngā wāhanga hanga me te tinei hei whakarite i te hanganga wāhanga tika me te whakamatao pai.
Kāore te tere whakamatao o te tinei e pā ana ki te wā whakaputa anake, engari ka pā hoki ki te pai o te whakawhiti i waenga i te austenite me te martensite. Ko te tere whakamatao e whakatau ana i te momo hanganga tioata ka hangaia, ā, e pā ana ki te pānga whakapakeketanga whakamutunga o te mea mahi. Ko te pāmahana whakamatao nui o te maitai boron he tata ki te 30℃/s, ā, mena ka nui ake te tere whakamatao i te pāmahana whakamatao nui ka taea te whakatairanga i te hanganga martensitic ki te whānuitanga nui. Ina iti iho te tere whakamatao i te tere whakamatao nui, ka puta ngā hanganga kore-martensitic pēnei i te bainite i roto i te hanganga tioata o te mea mahi. Heoi, ko te teitei ake o te tere whakamatao, ko te pai ake, ko te teitei ake o te tere whakamatao ka arahi ki te pakaru o ngā wāhanga kua hangaia, ā, me whakatau te awhe tere whakamatao tika i runga i te hanganga rauemi me ngā tikanga tukatuka o ngā wāhanga.
Nā te mea he hononga tika te hoahoa o te paipa whakamatao ki te rahi o te tere whakamatao, ko te tikanga he hoahoa te paipa whakamatao mai i te tirohanga o te pai o te whakawhiti wera mōrahi, nō reira he uaua ake te ahunga o te paipa whakamatao kua hoahoatia, ā, he uaua ki te tiki mā te keri miihini i muri i te otinga o te whakarewanga pokepokea ai. Hei karo i te herea e te tukatuka miihini, ko te tikanga o te pupuri i ngā awa wai i mua i te whakarewanga pokepokea ai te tikanga e whiriwhiria whānuitia ana.
Nā te mea he roa te wā e mahi ana i te 200℃ ki te 880~950℃ i raro i ngā āhuatanga makariri me te wera nui, me pai te pakari o te hanganga me te kawe wera o te rauemi tā wera, ā, me ātete hoki ki te waku wera kaha e puta mai ana i te papa i te pāmahana teitei me te pānga o te kakahu o ngā matūriki o te paparanga waikura e taka ana. Hei tāpiri, me pai hoki te ātete o te rauemi pokepokea ki te waikura hei whakarite i te rere maeneene o te paipa whakamatao.
Te kuti me te wero
Nā te kaha o ngā wāhanga i muri i te tā wera ka eke ki te 1500MPa, ki te whakamahia te tapahi me te wero, ka nui ake te taumaha o ngā taputapu, ā, he nui te pakaru o te mata tapahi. Nō reira, he maha ngā wā ka whakamahia ngā wae tapahi taiaho hei tapahi i ngā taha me ngā kōhao.
4. Ngā momo noa o te maitai tā wera
Te mahi i mua i te tānga
Te mahi i muri i te tānga
I tēnei wā, ko te momo noa o te maitai tā wera ko te B1500HS. Ko te kaha kume i mua i te tā i te nuinga o te wā kei waenga i te 480-800MPa, ā, i muri i te tā, ka taea e te kaha kume te eke ki te 1300-1700MPa. Ara, ko te kaha kume o te pereti maitai 480-800MPa, mā te tā wera, ka taea te whiwhi i te kaha kume o ngā wāhanga tata ki te 1300-1700MPa.
5. Te whakamahinga o te maitai tā wera
Mā te whakamahi i ngā wāhanga tā wera ka taea te whakapai ake i te haumaru tukinga o te motuka, ā, ka taea hoki te whakaiti i te mama o te tinana o te motuka mā. I tēnei wā, kua whakamahia te hangarau tā wera ki ngā wāhanga mā o te tinana o ngā motuka pāhihi, pērā i te motuka, te pou A, te pou B, te parepare, te kurupae tatau me te reera tuanui me ētahi atu wāhanga. Tirohia te ahua 3 i raro nei hei tauira mō ngā wāhanga e tika ana mō te taumaha māmā.

Pikitia 4: Raina Pēhi Wera 1200 Tīni mīhini jiangdong
I tēnei wā, kua tino pakari, kua pumau hoki ngā otinga whakaputanga perehi waipēhi wera a JIANGDONG MACHINERY, kei roto i te mara hanga wera o Haina te taumata matua, ā, hei heamana tuarua mō te peka mīhini hanga o te Rōpū Utauta Mīhini o Haina me ngā wae mema o te Komiti Paerewa Mīhini Hanga o Haina, kua whakahaerehia e mātou te rangahau me te mahi tono o te mahi wera tere-rahi ā-motu o te maitai me te konumohe, he mea nui tēnei ki te whakatairanga i te whanaketanga o te umanga wera i Haina me te ao katoa.
