Ngā mata parau maitai konupora kounga teitei, ngā wāhanga parau ahuwhenua
I roto i te mahi ahuwhenua, ko te hea parau, hei wāhanga matua e pa ana ki te oneone, e mahi ana i ngā mahi tapahi me te huri, ka whakatau tika i te whai huatanga o te mahi me te utu. He mea hanga tēnei hea parau mā te whakamahi i te hangarau maimoatanga wera matatau me te maitai boron/manganese kaha-teitei, i hangaia mō te mahi ahuwhenua kaha-nui, roa-te-wā, me te whai kia pai ake te wheako ahuwhenua a ngā kaiwhakamahi, kia kore ai e māharahara.
Ngā Rauemi Pai Rawa, Te Roa o te Ora Ratonga: He mea hanga tēnei hua i te maitai puna 65Mn kounga teitei (te maitai 30MnB/boron rānei, i runga i te whakamahinga motuhake), he nui ake te pakeke me te pakari i te rino maka noa, i te maitai waro rānei. Mā roto i ngā tukanga maimoatanga wera maha (te tinei whānui + te whakamahana ā-rohe), ka eke te pakeke o te mata o te mata me te mata tapahi ki te 38-45 HRC, ka whakapai ake i te ātete ki te kakahu me te pupuri tonu i te kaha me te pakari. Ina whakamahia i roto i te oneone onepu, i te whenua pakari rānei kei roto te kirikiri, ka taea te roa ake te ora ratonga mā te 30%-50% i te whakataurite ki ngā hea parau noa, ka whakaiti i te wā kore mahi mō ngā whakakapinga me te tuku i te mahi ahuwhenua tere ake.
Hoahoa Hikoi mō te Tapahi Oneone Maeneene: Ko te āhua o te hua he mea hanga kia rite ki ngā mātāpono o te nekehanga wai kua whakangawaritia, me te mata koko maeneene, papatahi, kāore he kōhao onepu me ngā kōhao. Ko ngā koki tapahi kua whakapaitia me te hanganga mata koi-ake ka whakaiti i te ātete i te wā e whakamahia ana, ka tapahi ngāwari i roto i te oneone, ā, ka tutuki he pānga pana taha me te hipoki pai. Ka uru ngāwari te mata koi ki roto i te oneone mai i ngā wāhanga tuatahi o te whakamahinga, ā, ka mau tonu tōna āhuatanga "whakakoi-ake" i roto i te wā, ka noho koi tonu, ka whakaiti i te ātete ki te kukume tarakihana, ā, ka penapena i te 5%-10% o te whakapaunga wahie.
Te ōritetanga tika me te kaha o te whakamahi: Ka kapi tēnei raupapa parau i ngā tauira maha tae atu ki ngā parau hurihuri waipēhi, ngā parau papa pokepoke, me ngā parau whakawātea whenua, e tuku ana i ngā kōwhiringa patu parau paerewa, toronga, me ngā patu parau āwhina. He hoahoa kōhao paerewa ngā hua, e whakarite ana i te hototahitanga teitei me te whakawhitiwhiti me ngā hea parau mai i ngā waitohu matua (pērā i a Reken, Kuhn, Glan, me ngā tauira o te whare hokohoko nui). He watea te tāutanga, kāore e hiahiatia he whakarerekētanga tāpiri mō te whakakapinga maeneene.
He tino kaha te whakahaere kounga, he ratonga muri-hoko kore āwangawanga. Ka whakamatautauria ia parau ki ngā āhuatanga me te pakeketanga i mua i te wehenga atu i te wheketere kia mau ai te mahi a te hua. E mārama ana mātou ki te uauatanga o te mahi ahuwhenua, ā, ka whakaratohia e mātou he whakapumautanga kounga pakari mā roto i ngā tukanga hanga tino tupato.
