Pūwero Parao Whakatō Rino Puna, he mīhini horoi ātete-mau mō te mahi ahuwhenua
I roto i te mahi parau hohonu o te whenua pāmu, ahakoa he iti te pito o te parau, ko te "mua" te mea e tino pāngia ana e te waku me te pānga o te oneone. [Ingoa Waitohu] Ko te pito parau ātete-mau kua whakarei ake, he mea hanga motuhake mō ngā tarakihana kaha-teitei me ngā parau hohonu, ka tautuhi anō i ngā paerewa pakari o ngā taputapu mīhini ahuwhenua me te mahi pai ki te uru ki te oneone me te roa o te ora ratonga, ka āwhina i a koe ki te aro atu ki ngā āhuatanga uaua maha, ā, ka whakatakoto i te turanga pakari mō te kotinga nui.
Rauemi taumata hōia, tino ātete ki te kakahu
E mōhio ana mātou ki te taiao uaua o ngā mahi mīhini ahuwhenua. He mea hanga tēnei hua ki te maitai manganese 65Mn kounga teitei, te maitai boron rānei (whakakīia kia rite ki te rauemi tuturu) i hangaia katoatia. Whai muri i tētahi tukanga whakamahana motuhake, ka taea e te pakeke o te mata tapahi te eke ki te HRC 48-52, e kore e whakarite noa i te koi o te mata tapahi kia tere ai te uru ki roto i te oneone, engari e whakarite ana hoki i te pakari teitei o te papa. Ahakoa i ngā wāhi he nui te onepu me te kirikiri, ka taea e ia te ātete pai ki te pakaru me te hurihuri o te mata, ā, ko tōna ātete ki te kakahu he nui ake i te ātete ki ngā whakarewa noa.
Ka whakaitihia te whakapaunga pūngao e te hoahoa miihini pūtaiao
Ka pā tika te āhua ā-ira o te pito parau ki te whakapaunga wahie me te whai huatanga o te mahi. He hoahoa mata ngāwari tēnei e whakamahia ana e tēnei hua, e arotau ana i te koki tapahi. Ehara i te mea ka taea e tēnei te whakaiti i te ātete waku ki te oneone, ka poto ake, ka maeneene ake hoki te haerenga whakauru, engari ka whai hua hoki te whakaiti i te kawenga kukume o te tarakihana. E whakaatu ana ngā raraunga whakamātautau tūturu, ki te whakaritea ki ngā pito parau pūngoi tuku iho, ka taea te whakaiti i te whakapaunga wahie mā te 5% -8%, ka tino tutuki ai te penapena pūngao me te whai huatanga teitei.
Te taunga tika, te whakakapinga tere
Hei wāhanga āwhina mō ngā mīhini ahuwhenua, he mea nui te ngāwari me te taunga o te tāutanga. E whai pūmau ana mātou i te rahi o ngā taringa iri o ngā waitohu mīhini ahuwhenua matua (pērā i a Leiken, Beisong, Dongfanghong, me ētahi atu) mō te hanga pokepoke, kia tika ai te tūnga o ngā kōhao tāutanga me te taunga pai ki te ringa parau, me te kore e hiahiatia he whakarerekētanga tuarua. I taua wā, ka taea e te hoahoa pūtu kua whakapaitia te tiaki i te pane pūtu kua mau, te ārai i te pakaru, me te whakaroa i te roa o te mahi a ngā whakapiri.
Pānga whakakoi-ā-koi, koi ake i te whakamahinga
Mā te ōwehenga rauemi ahurei ka taea e te pito parau poutū te hanga i tētahi hanganga taratara iti i te wā e pakaru ana te oneone i te wā e whakamahia ana, ka hua ake he pānga "mata huri-ake". I te roanga o te wā mahi kāinga, ka noho koi tonu te pito parau kia rite ai te hohonu o te parau me ngā kongakonga oneone pai, ka hangaia he taiao tino pai mō te rui me te whakatipu tipu.
