Ngā taputapu mīhini ahuwhenua: ngā parau whai hua

Whakaahuatanga Poto:

He mea hanga tēnei mata parau ahuwhenua mai i te maitai motuhake kounga teitei, ā, ka tukuna ki te whakamahana whānui me te tinei i te mata, ka hua ake he kaha teitei me te ātete pai ki te kakahu. Ko tōna hoahoa angiangi, piko hoki ka whakaiti i te ātete ki te parau, ka taea ai te huri me te pakaru oneone. Mā te pito koi o te mata ka whakarite kia maeneene te urunga oneone me te hohonu o te parau. He hototahi whānui ki ngā tauira parau maha, he taputapu pai mō te whakapai ake i te pai o te mahi me te whakaiti i te whakapaunga wahie, ka whakarato tautoko pono mō te whakatipu whenua ahuwhenua hohonu me te tino tupato.

Ko te hea parau te wāhanga matua o te parau papa pokepoke, e kiia ana ko te "paionia o te oneone." Ko tana mahi matua he tomo, he tapahi, he wawahi, he huri i te oneone i te wā e whakatipu ana, hei whakaoti i te wetewete tuatahi o te whenua pāmu, hei whakatakoto i te turanga pakari mō te rui. Ka hangaia tēnei hua mā te whakamahi i ngā hangarau matatau me te pūtaiao rauemi, ko te whāinga he whakarato i ngā pāmu hou ki tētahi otinga whakatipu pakari, whai hua, me te iti o te whakapaunga.

1, Rauemi: I whakamahia mai i te 65Mn (65 maitai manganese) te maitai boron pai ake rānei, ā, i raro i te maimoatanga tinei me te whakamahana whānui, kia tutuki ai te pakeke mata o te HRC 48-55.

2, Tukanga: Ka taea te whakamahi i te hangarau whakakikorua tokotoko whakarewa ātete-kakahu, i te paninga koranu mārō tungsten carbide rānei ki te mata tapahi, kia roa ake ai tōna roanga mahi mā te 2-3 ngā wā ki te whakarite ki ngā waru noa, kia tino whakaitihia ai te auau whakakapinga me ngā utu mō te wā roa.

3, Hoahoa Āhuahanga: Ko te mata piko, kua arotauhia i runga i ngā āhuatanga wai me ngā tikanga oneone, he piko tika hei whakarite kia maeneene te urunga o te oneone, kia tere te pakaru o te oneone, kia whai hua ai te hurihanga me te hipoki o te oneone.

4, Te Mata Tapahi Whakakoi-ā-Whaiaro: Mā te hoahoa koki tapahi ahurei ka mau tonu te kaha tapahi koi i te wā e whakamahia ana, ka whakaiti i te ātete me te whakaiti nui i te whakapaunga wahie o te tarakihana (tata ki te 10-15%).
