Pōro huri uku Ko ngā whakaritenga rauemi e whakaatahia ana i roto i ngā āhuatanga e whai ake nei, hei whakarite i te tukanga huri maeneene me te pānga huri o te whai huatanga teitei:
1. Te pakeke o ngā rauemi:
- He tino pakari te pōro huri uku, ā, he ātete ki te pakaru, nō reira he pai mō te huri i ngā rauemi he iti te pakari.
- Ina hurihia ngā rauemi he tino pakeke rawa, ka pāngia pea te pōro huri uku, ka pāngia tōna roa o te mahi me tōna pānga huri.
2. rahi matūriki rauemi:
– Ko te rahi mōrahi o te matūriki o te rauemi e hurihia ana me ≤1mm mō te huri porowhita-tuwhera me te ≤2mm mō te huri porowhita-kati.
– He whakaritenga motuhake anō hoki mō te rahi matūriki toharite o te rauemi huri, pērā i te mira tuwhera ≤ R0.08 @ 35%, te mira kati ≤ R0.08 @ 45%.
– Ko ēnei whakaritenga rahi matūriki hei whakarite i te whai huatanga o te huri me te whakahaere i te pakaru o te pōro huri uku.
3. Makuku rauemi:
– Ko te makuku toharite o te rauemi e hurihia ana me ≤1.5%. Mēnā he nui rawa te makuku, ka piri pea te rauemi ki ngā pōro huri, ka pā ki te pānga huri me te mahi a te taputapu.
4. ngā āhuatanga rauemi:
– He pai ngā pōro huri uku mō ngā rauemi rerekē, pērā i ngā pōro uku alumina teitei e pai ana mō te huri i te konganuku konumohe, te konganuku siliceous me ētahi atu konganuku me ētahi atu rauemi e hiahiatia ana he matūriki iti; he pai ngā pōro huri zirconia mō te huri i ngā rauemi he pakeke teitei; he pai ngā pōro huri silicon carbide mō te huri i ngā rauemi pāmahana teitei.
– Ko te pumau matū o te rauemi me te tauhohenga matū ki ngā pōro huri he mea anō hei whai whakaaro ki te karo i te poke, i te kino rānei o ngā pōro huri i te wā e huri ana.
5. Te parakore o ngā rauemi:
– He tino pai ngā pōro huri uku mō ngā rauemi huri e hiahia ana kia tino parakore nā te mea he tino parakore ō rātou āhuatanga, ā, kāore e poke i te rauemi i te wā e huri ana.
6. Te āhua me te rere o te rauemi:
– Ka pā te āhua me te rere o te rauemi ki tōna tohatoha me te pānga huri i roto i te tukanga huri. Mā te āhua tika me te rere o te rauemi ka pai te huri ōrite me te whakawhiti pūngao whai hua.
Ko ngā whakaritenga matua mō te poro huri uku ko te pakeke o te rauemi, te rahi o te matūriki, te haumākū, te āhua, te parakore me te rere o te āhua, me ērā atu mea. I te wā e whiriwhiri ana i ngā poro huri uku, me arotake me te whiriwhiri kia rite ki ngā āhuatanga motuhake o te rauemi me ngā whakaritenga huri kia pai ai te rere o te tukanga huri me te whai huatanga o te huri.
