1. Tātaritanga hanganga
(1) Tēneitakirere pūrerehuahe porowhita te hanganga, he rite ki te keke, e honoa ana te kōhao o roto, ā, e tautokona ana e ngā rara whakakaha e 8, e hono ana te kōhao Φ620 o runga ki te kōhao o roto, ā, ko te toenga o tetakirereKi te kati, he uaua te whakatika i te pūtake onepu, ā, he ngāwari hoki te whakapēhanga. He nui ngā uauatanga o te putanga hau me te horoinga o te kōhao o roto, e whakaaturia ana i te Pikitia 1.
He rerekē rawa te matotoru o te pakitara o ngā whakarewanga, ko te matotoru mōrahi o te pakitara ka eke ki te 380mm, ā, ko te matotoru iti rawa o te pakitara he 36mm anake. Ina totoka te whakarewanga, he nui te rerekētanga o te pāmahana, ā, ka taea e te whakahekenga koretake te whakaputa i ngā kōhao whakahekenga me ngā hapa o te pūwero whakahekenga, ka puta ai te turuturu o te wai i roto i te whakamātautau waipēhi.
2. Te hoahoa tukanga:
(1) Kei te whakaatuhia te mata wehewehe i te Pikitia 1. Whakatakotoria he kōhao ki te pito o runga o te pouaka, hangaia he matua onepu katoa ki te kōhao waenga, ā, whakaroahia te pane matua kia tika ai te whakamau i te matua onepu me te nekehanga o te matua onepu ina hurihia te pouaka. Kia pumau, ko te roa o te pane matua cantilever o ngā kōhao matapo e rua i te taha he roa ake i te roa o te kōhao, kia anga ai te pokapū o te taumaha o te matua onepu katoa ki te taha o te pane matua kia mau ai, kia pumau ai hoki te matua onepu.
Ka whakamahia he pūnaha ringihanga ā-haurua-katia, ∑F roto: ∑F whakapae: ∑F tika=1:1.5:1.3, ka whakamahia e te sprue he ngongo uku me te diameter o roto o Φ120, ā, e rua ngā pereki ātete 200×100×40mm ka whakatakotoria ki raro hei ārai i te rino rewa mai i te urunga tika. Mō te pokepokea ai te onepu pānga, ka tāutahia he tātari uku pahuka 150×150×40 ki raro o te oma, ā, 12 ngā ngongo uku me te diameter o roto o Φ30 ka whakamahia mō te oma o roto hei hono ōrite ki raro o te whakarewanga mā te tāke kohikohi wai i raro o te tātari hei hanga i tētahi kaupapa ringihanga ringihanga raro, e whakaaturia ana i te Pikitia 2.
(3) Whakatakotoria he 14 ngā kōhao hau ∮20 ki roto i te pokepokea o runga, whakatakotoria he kōhao hau matua onepu Φ200 ki waenganui o te pane matua, whakatakotoria he rino matao ki roto i ngā wāhanga matotoru me ngā wāhanga nunui hei whakarite i te pakari taurite o te whakarewanga, ā, whakamahia te mātāpono whakawhanuitanga whakairoiro hei whakakore. Ka whakamahia te whakaneke whāngai hei whakapai ake i te hua o te tukanga. Ko te rahi o te pouaka onepu he 3600×3600×1000/600mm, ā, ka whakarewaina ki te pereti maitai matotoru 25mm hei whakarite i te kaha me te pakari, e whakaaturia ana i te Pikitia 3.
3. Whakahaere tukanga
(1) Te Whakatauira: I mua i te whakatauira, whakamahia he tauira paerewa Φ50×50mm hei whakamātautau i te kaha pēhi o te onepu kapia ≥ 3.5MPa, ā, whakaukia te rino makariri me te kaitahuri kia mōhio ai kei te rawaka te kaha o te pokepokea onepu hei whakakore i te karāpiti i puta mai i te wā e totoka ana te rino rewa. Te whānui matū, me te ārai i te rino rewa kei pā ki te wāhanga kaitahuri mō te wā roa, kia kore ai e horoia te onepu.
Te Hanga Matua: Ka wehea te matua onepu kia 8 ngā wāhanga ōrite e 8 ngā rara whakapakari, ka honoa mā roto i te kōhao waenga. Kāore he wāhanga tautoko me te putanga hau atu i te pane matua waenga. Ki te kore e taea te whakapūmau i te matua onepu me te putanga hau, ka puta te nekehanga o te matua onepu me ngā kōhao hau i muri i te ringihanga. Nā te mea he nui te horahanga whānui o te matua onepu, ka wehea kia 8 ngā wāhanga. Me nui te kaha me te pakari kia kore ai e pakaru te matua onepu i muri i te tukunga o te pokepokea ai, ā, kia kore ai hoki e pakaru i muri i te ringihanga. Ka puta he āhua rerekē, kia rite ai te matotoru o te pakitara o te whakarewanga. Nā tēnei take, i hangaia e mātou he wheua matua motuhake, ā, i herea ki te wheua matua ki te taura whakapūhau hei kukume i te hau putanga hau mai i te pane matua kia pai ai te kiato o te pokepokea ai onepu i te wā e hangaia ana te matua. E ai ki te whakaaturanga i te Pikitia 4.
(4) Pouaka kati: I te mea he uaua ki te horoi i te onepu i roto i te kōhao o roto o te takirere pūrerehua, ka pania te matua onepu katoa ki ngā paparanga e rua o te peita, ka paraihia te paparanga tuatahi ki te peita zirconium waipiro (tohu Baume 45-55), ā, ka pania te paparanga tuatahi ka tahuna. I muri i te maroke, pania te paparanga tuarua ki te peita konupora waipiro (tohu Baume 35-45) hei ārai i te piri o te maka ki te onepu me te sintering, e kore e taea te horoi. Ka whakairihia te pane matua ki runga i te paipa maitai Φ200 o te hanganga matua o te wheua matua me ngā tīwiri M25 e toru, ka mau me te raka ki te pouaka onepu pokepokea o runga me ngā taupoki tīwiri, ā, ka tirohia mēnā he ōrite te matotoru o te pakitara o ia wāhanga.
4. Te tukanga whakarewa me te ringihanga
(1) Whakamahia te rino poaka kounga teitei Q14/16# a Benxi iti-P, S, Ti, ka tāpirihia ki te ōwehenga o te 40%~60%; ko ngā huānga iti pēnei i te P, S, Ti, Cr, Pb, me ētahi atu, he mea tino whakahaere i roto i te maitai para, ā, kāore e whakaaetia te waikura me te hinu, ko te ōwehenga tāpiri he 25%~40%; me horoi te utu i whakahokia mai mā te pupuhi pupuhi i mua i te whakamahinga kia pai ai te ma o te utu.
(2) Te mana whakahaere o ngā wāhanga matua i muri i te oumu: C: 3.5-3.65%, Si: 2.2%-2.45%, Mn: 0.25%-0.35%, P≤0.05%, S: ≤0.01%, Mg (toenga): 0.035% ~0.05%, i raro i te kaupapa o te whakarite i te porowhita, me tango te rohe o raro o te Mg (toenga) i te mea ka taea.
(3) Te maimoatanga werohanga spheroidization: ka whakamahia ngā spheroidizers iti-konupora me iti-whenua-onge, ā, ko te ōwehenga tāpiri he 1.0%~1.2%. Mā te tikanga horoi tuku iho, ka hipokina te 0.15% o te werohanga kotahi ki runga i te nodulizer i raro i te putea, ā, ka oti te werohanga spheroidization. Kātahi ka tukuna te para ki raro i te kirimana mō te werohanga tuarua o te 0.35%, ā, ka mahia te werohanga rere o te 0.15% i te wā e ringihia ana.
(5) Ka whakamahia te tukanga ringihanga tere i te pāmahana iti, ko te pāmahana ringihanga he 1320°C~1340°C, ā, ko te wā ringihanga he 70~80 hēkona. Kāore e taea te whakakore i te rino rewa i te wā ringihanga, ā, me kī tonu te kapu wai hei ārai i te hau me ngā mea whakauru mai i te urunga ki roto i te pokepokea ai mā roto i te pūwero.
5. Ngā hua whakamātautau whakarewa
(1) Whakamātauria te kaha kume o te poraka whakamātautau whakarewa: 485MPa, te roa: 15%, te pakeketanga Brinell HB187.
(2) Ko te tere whakaporoporo he 95%, ko te rahi o te karāpeti he taumata 6, ā, ko te pearlite he 35%. Kei te whakaatuhia te hanganga whakarewa i te Pikitia 5.
(3) Kāore i kitea he hapa tuhi i roto i te kitenga hapa tuarua UT me MT o ngā wāhanga nui.
(4) He papatahi, he maeneene te āhua (tirohia te Pikitia 6), kāore he hapa whakarewa pērā i te whakaurunga onepu, ngā whakaurunga para, ngā kati makariri, me ētahi atu, he ōrite te matotoru o te pakitara, ā, e tutuki ana ngā inenga i ngā whakaritenga o ngā tuhi.
(6) Kāore i kitea he turuturu i te whakamātautau pēhanga waipēhi 20kg/cm2 i muri i te tukatuka
6. Whakamutunga
E ai ki ngā āhuatanga hanganga o tēnei takirere pūrerehua, ka whakatauhia te raruraru o te kore pumau me te ngāwari o te hurihanga o te matua onepu nui i waenganui me te horoi onepu uaua mā te aro nui ki te hoahoa o te mahere tukanga, te hanga me te whakapiri i te matua onepu me te whakamahi i ngā paninga zirconium. Mā te whakatakoto i ngā kōhao hau ka karohia te tūponotanga o ngā pore i roto i ngā whakarewanga. Mai i te pūnaha whakahaere utu oumu me te pūnaha oma, ka whakamahia te mata tātari uku pahuka me te hangarau tatau uku hei whakarite i te parakore o te rino rewa. Whai muri i ngā maimoatanga werohanga maha, kua eke te hanganga whakarewa o ngā whakarewanga me ngā momo mahi whānui ki ngā whakaritenga paerewa a ngā kiritaki.
