I roto i ngā ahumahi keri, keri rua, me te tukatuka tākai o te ao, ko te roa o te mahi o ngā wāhanga pakaru o te kuru te mea tika hei whakatau i te pai o te whakaputanga, te wā whakamutu, me te utu katoa o te mana pupuri (TCO). I te wā e whiriwhiri ana i ngā wāhanga pakaru pēnei i ngā pereti kauae, ngā raina kōne, ngā pae pupuhi, me ngā pito hama, he nui te aro o te nuinga o ngā kaiwhakahaere ki te hanganga rauemi, pēnei i te kounga maitai manganese, te ihirangi chromium rānei, engari ka warewarehia tetahi mea nui e whakatau ana i te mahi whakamutunga o te wāhanga: te maimoatanga wera. E whakaatu ana ngā raraunga whakarewa ahumahi ahakoa he rite tonu ngā hanganga matū, ka taea e ngā wāhanga pakaru e rua te rerekētanga 50-100% i roto i te roa o te mahi, nā te rerekētanga o ngā tukanga maimoatanga wera anake. Mō ngā kaiwhakahaere kuru, ko te mārama ki te mahi a te maimoatanga wera ehara i te mōhiotanga hangarau anake - he taputapu matua ki te whiriwhiri i ngā wāhanga pakaru kounga teitei me te karo i ngā pakaru wawe utu nui. Ka wehewehea e tēnei tuhinga ngā mātāpono matua o te maimoatanga wera mō ngā wāhanga pakaru o te kuru, ngā tukanga paerewa mō ngā rauemi matua, me te pehea e puta ai ngā painga mahi tūturu mai i te maimoatanga wera kua arotauhia.
He aha te take kāore e taea te whiriwhiri i te maimoatanga wera mō ngā wāhanga kākahu o te crusher
Ko ngā wāhanga kakahu kua whakarewahia, mai i te pokepokea ai te whare hanga, he hanganga whakarewa kore pumau, he pakeke kore taurite, he ahotea toenga ā-roto, me ngā pūhui carbide pakarukaru e tino whakawhāiti ana i te mahi. Ko te maimoatanga wera he tukanga whakarewa whakahaere e whakamahi ana i ngā huringa whakamahana, pupuri, me te whakamatao tika hei whakarerekē i te hanganga moroiti o roto o te konganuku, e whakatuwhera ana i te kaha katoa o ōna huānga koranu. Ko te wero matua mō ngā wāhanga kakahu kuru katoa ko te whakataurite i ngā āhuatanga taupatupatu e rua: te ātete ki te pakū hei tu atu i te tapahi mai i te toka pakeke, me te pakari hei tu atu i te pakaru i raro i te pānga nui. Ki te kore he maimoatanga wera tika, kāore e taea te whakatutuki i tēnei taurite. Hei tauira, he pai rawa te ātete kakahu o te whakarewa konupora-teitei, engari ki te kore he maimoatanga wera kua pai ake, ka pakarukaru rawa ki te tu atu i te pānga ngawari, ka arahi ki te pakaru kino, ki te pakaru rānei i waenganui o te mahi.
Ngā Tukanga Maimoatanga Wera Paerewa mō ngā Rauemi Wāhanga Kakahu Matua
He tikanga maimoatanga wera motuhake tō ia rauemi ātete-kakahu, e hāngai ana ki tōna hanganga matū me te whakamahinga e hiahiatia ana. Mō ngā whare hanga whakarewa ngaio, ko te piripono ki ēnei tukanga te tūāpapa o ngā wāhanga mahi-teitei, pumau.
Tuatahi, ko te whakapakeke wai mō te maitai manganese austenitic, te paerewa koura mō ngā wāhanga kuru tuatahi. Ko ngā maitai manganese, tae atu ki te Mn13Cr2 e whakamahia whānuitia ana me te Mn18Cr2 pakari-teitei, e whakawhirinaki ana ki tētahi hanganga austenitic kotahi-wāhanga hei whakaputa i tō rātou āhuatanga whakapakeke mahi motuhake: ina pāngia e te pānga nui, ka whakapakeke te mata hei ātete i te pakū, ko te matua ia ka mau tonu te pakari hei ārai i te pakaru. Ko te tukanga whakapakeke wai me whakamahana te whakarewa ki te 1050-1100°C tika, me te pupuri i tēnei pāmahana hei whakarewa i ngā warowaihā ki roto i te hanganga, kātahi ka tinei tere ki roto i te wai hei raka i te hanganga austenitic. Ahakoa he iti noa te peka, pērā i te kore e ranea te wā pupuri, te puhoi rānei o te whakamatao, ka puta he puranga warowaihā, ka whakaiti i te pakari o te wāhanga tae atu ki te 70% ka ngawari ki te pakaru ohorere.
Tuarua, te tinei me te whakamahana mō te rino ma te konukōre-teitei, he mea tino pai mō te kuru tuarua me te tuatoru o te rino konukōre-teitei, te iti o te pānga. Ko te ātete kakahu tino pai o te rino konukōre-teitei i ahu mai i ōna matūriki karāhe konukōre-teitei me te anga martensitic. Ko te tukanga maimoatanga wera he huringa tinei e āta whakahaeretia ana hei hanga i te hanganga martensitic, ā, muri iho ka whai i te taahiraa whakamahana hei whakamama i te ahotea o roto me te whakaiti i te austenite pakarukaru e mau tonu ana. Ka whakatauritehia e tēnei tukanga te pakeke mōrahi mō te ātete kakahu me te kaha e ranea ana hei karo i te pakaru, ka roa ake te ora ratonga tae atu ki te 3x i te maitai konukōre paerewa i roto i ngā tono wera-teitei.
Ngā Painga Tūturu o te Maimoatanga Wera Arotau
Mō ngā kaiwhakahaere kuru, ko te haumi ki ngā wāhanga pakaru me te maimoatanga wera tino whakahaere ka puta he hua pūtea me te mahi ka taea te ine. Ka roa ake te ora ratonga mā te 30-80% ki te whakaritea ki ngā wāhanga he iti iho i te paerewa te maimoatanga wera, ka whakaiti i te auau whakakapinga me ngā utu mahi e pā ana. Ka whakakorea hoki te wā kore mahi i whakaritea nā te pakaru ohorere o ngā wāhanga, he take noa ki ngā wāhanga kāore i tukatukahia kia werahia ka taea te utu i ngā tekau mano tāra i roto i te hanga ngaro ia haora mō ngā keri waenga-rahi. Hei whakamutunga, ka whakaitihia te TCO whānui: ahakoa he iti ake te utu o mua mō ngā wāhanga kua tukatukahia kia werahia, ka tukuna e rātou he 2-3 ngā wā roa ake o te ora ratonga, ka tapahia te whakapaunga wāhanga pakaru ā-tau tae atu ki te 40%.
