He koko oneone, he pito parau āhua-V, he wāhanga mīhini ahuwhenua
1. Te parau hohonu: Pakaruhia te paraharaha parau, wetekina te oneone hohonu, whakapai ake i te hau o te oneone me te kaha ki te pupuri wai.
2. Te whakarite oneone: Wetekina, kuruhia te oneone kia pai ai te āhua mō te rui me te whakatipu tipu.
3. Te whakamahinga o ngā mīhini ahuwhenua: Ka tāuta ki runga i ngā mīhini oneone o raro, ngā mīhini huri, me ētahi atu.
mō te parau hohonu i ngā mara, i ngā māra hua rākau me ētahi atu āhuatanga.
He mea hanga tēnei hua mai i ngā rauemi koranu kaha-teitei pērā i te maitai manganese 65Mn me te maitai boron 30MnB, ā, he mea hanga ngātahi mā te hanga wera, kia mau ai te matotoru o te hanganga o roto, kia kore ai hoki e pāngia e te porosity me ngā raruraru onepū e kitea ana i roto i ngā whakarewanga. Nō muri mai, mā roto i ngā tukanga whakamahana tinei isothermal me te whakamahana, ka eke te pakeke o te mata o te parau ki te HRC 38-45, ā, ka mau tonu te pakari o te uho. Mā tēnei āhuatanga "pakari ki waho, pakari ki roto" ka taea te tu atu ki ngā pānga kino mai i ngā kōhatu me ngā pakiaka rākau (me te kore e whati) me te pupuri i te mata tapahi koi mō te wā roa, ka roa ake te huringa whakakapinga.
1, Hoahoa mata piko kua whakatikatikaina: I arotauhia e mātou te koki tapahi me te piko o te mata parau. Mā tēnei hoahoa ka whakaitihia te piri o te oneone, ka whakaitihia te ātete ki te parau mā te 15%-20% pea, ā, ka penapenahia te wahie o te tarakihana me te whakapai ake i te whai huatanga o te mahi.
2、Hangarau whakakoi-ake: Mō ngā mata tapahi kua tino pakaru, ka whakamahia e mātou he ōwehenga rauemi motuhake. I te wā e whakamahia ana, ka puta he pānga "whakakoi-ake" i te mata mahi o te mata parau, kia koi tonu ai te mata tapahi, kia kore ai hoki e "tōia" e puta mai i te whakapōuri. Mā tēnei ka maeneene te hurihanga o te mata, ka piri te uhi.
3, Atanga tāutanga tika: Ka hangaia ngā pokepokea kia rite ki ngā paerewa wheketere taketake, me te whakahaere i te tawhiti o ngā kōhao tāutanga me ngā ātete mata tūnga i roto i te awhe tino iti, kia 100% te taunga ki te pou parau me te hea parau. Ehara i te mea ka māmā noa te tukanga tāutanga engari ka ārai hoki i te wetewete o te pūtu, te whakarerekētanga rānei o te mata i puta mai i ngā āputa nui.
He whānui te hototahi o tēnei raupapa parau ki ngā momo taputapu parau whenua pērā i ngā parau papa pokepoke, ngā parau hurihuri, me ngā parau waikeri. Ahakoa e whakamahia ana mō te wetewete hohonu me te parau whenua i muri i te kotinga, mō te wawahi oneone me te whakarite i mua i te rui rānei, e whakaatu ana i te tino ngāwari ki te urutau. He tino pai mō ngā āhuatanga whenua uaua i ngā rohe pērā i te rohe oneone mangu o te Rawhiti-mā-rāwhiti o Haina, te rohe oneone onepu o te Rawhiti-mā-rāwhiti o Haina, me te rohe oneone whero o te Tonga o Haina.
