FAKATOKANGA: Ko nga whakaritenga motuhake mo te rahi ka taea te tuku.
Ka whakamahia nuitia i roto i te Ahumahi
- Mo te hanga maitai o te oumu arc hiko
- Mo te oumu ūkuikui Kōwhai
- Hoatu ki te oumu silicon Ahumahi, parahi whakarewa ranei.
- Hoatu ki te Whakapai i te rino i roto i nga oumu koko me etahi atu mahi whakarewa
Me pehea te whiriwhiri i te Hiko Kawhata Tika
Ina tae mai ki te kowhiri i te hiko graphite tika, he maha nga mea hei whakaaro.
- Tuatahi, he mea nui te kounga o te hiko.Ko te hiko o te kounga teitei ka nui ake te ahua o te hanganga, ko te tikanga he iti ake te pakaru me te pakaru.
- Tuarua, me whiriwhiri te rahi o te hiko i runga i te whakatauranga hiko o te EAF, me nga oumu nui e hiahia ana kia nui ake nga hiko.
- Tuatoru, me whiriwhiri te momo hiko i runga i te karaehe rino, nga tawhā whakahaere, me te hoahoa oumu.Hei tauira, he pai ake te hikohiko UHP (Ultra High Power) ki nga oumu hiko teitei, i te mea he pai te hiko HP (High Power) mo nga oumu hiko-waenganui.

Rangatira Kounga Mata
1.Ko nga hapa me nga kohao kia kaua e neke atu i te rua nga waahanga i runga i te mata hiko graphite, a ko nga hapa me te rahi o nga kohao kaore e whakaaetia kia nui atu i nga raraunga i te ripanga i raro nei.
2.Kare he kapiti whakawhiti i runga i te mata hiko.Mo te kapiti roa, ko tona roa kia kaua e neke ake i te 5% o te porowhita hiko kauwhata, me noho tona whanui i roto i te awhe 0.3-1.0mm.Ko nga raraunga kapiti roa kei raro i nga raraunga 0.3mm kia iti
3.Ko te whanui o te waahi taratara(pango) i runga i te mata hiko kauwhata kia kaua e iti iho i te 1/10 o te porowhita hiko kauwhata, me te roa o te waahi taratara(pango) i runga i te 1/3 o te roanga hiko kauwhata. e kore e whakaaetia.
