Ko te mate te wāhanga matua o te mira pere. Ā, koinei te kī ki tete hanga pire whāngaiE ai ki ngā tatauranga kāore anō kia oti, ko te utu mō te mate o te mira pirepire e neke atu i te 25% o te utu tiaki o te awheawhe whakaputa katoa. Mō ia pikinga ōrau o ngā utu, ka heke tō whakataetae mākete mā te 0.25%. Nō reira, he mea tino nui ngā whakaritenga mō te mira pirepire.
He tohunga ngaio a Shanghai Zhengyi (CPSHZY)mira pellet whāngaikaiwhakarato i Haina. Ka tukuna e mātou he mira pellet mate mowhiti, he mira pellet mate papatahi me tengā wāhanga mira pereti, pērā i te mate papatahi, te mate mowhiti, te roera mira pire, me ētahi atu wāhanga mō te mīhini pire.
1.Rauemi mate mira pire
Ko te nuinga o te wā, he mea hanga te mate mira pire ki te maitai waro, te maitai hanganga koranu, te maitai kowiri tira rānei mā te hanga, te miihini, te keri poka, me ngā tukanga maimoatanga wera. Ka taea e te kaiwhakamahi te whiriwhiri i runga i te waikura o te rauemi mata matūriki. Me hanga te rauemi o te mate mira pire ki te maitai hanganga koranu, ki te mowhiti kowiri tira rānei.
Ko te maitai hanganga waro, pērā i te maitai 45, ko tōna pakeke maimoatanga wera he 45-50 HRC te tikanga, he rauemi mowhiti mate iti-te kounga, he ngoikore tōna ātete kakahu me te ātete waikura, ā, kua whakakorea rawatia.
He maitai hanganga koranu, pērā i te 40Cr, 35CrMo, me ētahi atu, he pakeke ake i te 50HRC te pakeke o te maimoatanga wera, ā, he pai hoki ngā āhuatanga miihini whakauru. He kaha te hanganga o tēnei rauemi, ā, he ātete ki te pakaru, engari ko te ngoikoretanga, kāore i te pai te ātete ki te waikura, inā koa mō te whāngai ika.
Ko te utu mō ngā mati mowhiti, he mea hanga ki ngā rauemi, ngā pire marigold, ngā maramara rakau, ngā pire kakau witi, me ētahi atu, he nui ake i te maitai kore waikura. Ko te 20CrMnTi me te 20MnCr5 he maitai koranu iti-waro, he rite tonu, engari ko te mea tuatahi he maitai Haina, ko te mea tuarua he maitai Tiamana. Nā te mea he onge te wātea o te Ti, he huānga matū, ki tāwāhi, ka whakamahia te 20CrMnTi, te 20CrMnMn rānei mai i Haina hei utu mō te 20MnCr5 mai i Tiamana, nō reira kāore i roto i te whānuitanga o te maitai hanganga koranu. Heoi, ko te paparanga whakapakeke o tēnei maitai ka herea e te tukanga waro ki te hohonutanga mōrahi o te 1.2 mm, he painga anō hoki tēnei o te utu iti o tēnei maitai.
Ko ngā rauemi o te kowiri tira ko te kowiri tira Tiamana X46Cr13, te kowiri tira Haina 4Cr13, me ētahi atu. He pai ake te pakari me te pakari o ēnei rauemi, he nui ake te pakeke o te maimoatanga wera i ngā maitai waro, he paparanga whakapakeke i ngā maitai waro, ā, he pai te ātete ki te kakahu me te waikura, ka roa ake te ora me te utu nui ake i ngā maitai waro. Nā te roa o te ora o te maitai mate kowiri tira, he iti te auau whakakapinga, nō reira he iti te utu mō ia tana.
Ko te tikanga, ko te rauemi mate mō te mira pellet mate mowhiti he maitai hanganga koranu me ngā rauemi kowiri tira.
2.Te ōwehenga kōpeketanga o te mate mira pellet
i=d/L
T=L+M
Ko M te hohonutanga o te kōhao kua whakaititia
Ko te ōwehenga kōpeketanga (i) ko te ōwehenga o te whānui o te kōhao o te mate (d) me te roa whai hua (L) o te mate.
E ai ki te āhua o te rauemi mata, ko te ōwehenga he 8-15. Ka whiriwhiria e te kaiwhakamahi te ōwehenga kōpeketanga o te mate, ka whakatikahia te ōwehenga kōpeketanga motuhake, pērā i te whiriwhiri i te ōwehenga kōpeketanga paku iti iho, he mea whai hua ki te whakanui ake i te putanga, te whakaiti i te whakapaunga pūngao, te whakaiti i te kakahu o te mowhiti pokepokea ai, engari ka whakaitihia hoki te kounga o ngā matūriki, pērā i te kore e tino kaha ngā pire, he wetewete te āhua me te roa, ā, he teitei te tere o te paura.
3.Te tere whakatuwheratanga o te mowhiti mate
Ko te tere whakatuwheratanga o te mate mira pere ko te ōwehenga o te horahanga katoa o te kōhao mate ki te horahanga katoa whai hua o te mate. I te nuinga o te wā, ko te teitei ake o te tere whakatuwheratanga o te mate, ko te teitei ake o te hua matūriki. I raro i te kaupapa o te whakarite i te kaha o te mate, ka taea te whakapai ake i te tere whakatuwheratanga o te mate mowhiti ki te mea ka taea.
Mō ētahi rauemi mata, i raro i te ōwehenga kōpeketanga whaitake, he angiangi rawa te pakitara o te mate mira pellet, ā, kāore e ranea te kaha o te mate, ā, ka puta te āhuatanga o te mate pahū i roto i te whakaputanga. I tēnei wā, me whakanui ake te matotoru o te mate mowhiti i raro i te kaupapa o te whakarite i te roa whai hua o te kōhao mate.
4.Te whakataurite i waenga i te mate mira pellet me te roera
Koinei te hangarau tino nui hei whakapai ake i te whai huatanga o te whakapūkara me te whakaroa i te ora o te mate. Me whakauru atu ki roto ngā āhuatanga e whā:
- He mowhiti hou te mate me te roera pēhanga hou, karohia te whakamahi nui i te roera pēhanga.
- E ai ki te āhua o ngā rauemi, me ngā āhuatanga o te momo mīhini, me whiriwhiri ngā momo rerekē o te roera pēhanga, kia tutuki ai te pai o te whakaputanga i waenga i te mate me te roera.
- Ko te mea nui ki te taurite o te āputa ko te pumau, ā, ko te mātāpono: me ngana kia wātea, kaua e pā ki te kaha.
- Whakahaerehia te tere whāngai, whakatikatikahia te tūranga roa me te poto o te waru whāngai hei whakahaere i te tūranga whāngai, te tohatoha paparanga rauemi.
5.Te tukatuka i te tukanga mate mira pellet
He tino uaua ngā kōhao mowhiti mō ngā taputapu tukatuka me te tukatuka, ā, mō te maitai kore waikura, me whakamahi ngā wiri pū motuhake me ngā taputapu maimoatanga wera korehau hei whakaputa i ngā kōhao mowhiti kounga teitei. Mā te tukanga tinei korehau pāmahana teitei pai rawa atu ka taea te whakapai ake i te pakari, te pakeke, te ātete ki te pakū, te kaha ngenge me te pakari o te maitai. Heoi, ko te kaha ki te whakarite i tētahi paparanga pakeke taurite mō ia kōhao me whai taumata tiketike o ngā pūkenga tukatuka me te wheako roa.
6.Te taratara o te mata o te mate o te pakitara o roto o te kōhao mate
He tohu nui anō hoki te taratara o te mata mō te kounga o te mowhiti mate. I te nuinga o te wā, mā te iti o te taratara o te mata o roto o te pakitara ka pai ake te kounga o te taunga, ka whakaiti i te kakahu, ka roa ake te ora o te mowhiti mate, engari ka piki ake te utu mō te tukatuka i te mowhiti mate.
Ka pā anō hoki te taratara o te kōhao mowhiti ki te ōwehenga kōpeketanga me te hanganga o ngā matūriki, tae atu ki te whai huatanga o te whakaputanga. I te ōwehenga kōpeketanga o te mate mowhiti kotahi, ka iti ake te uara taratara, ka iti ake te ātete ki te whakaputanga o ngā maramara rakau, o te whāngai rānei, ka maeneene ake te tukunga, ka teitei ake te kounga o ngā pirepire e whakaputaina ana, ā, ka teitei ake te whai huatanga o te whakaputanga. Ka taea e te tukatuka pai o te kōhao mate mowhiti te tae ki te 0.8-1.6 maikorona, ko te taratara o te mate mowhiti he tata ki te 0.8 maikorona, ko te mīhini tika i runga i te rauemi whakakorekore, kāore he huri.
