Nga Waahanga Hiko Kawhata I roto i te Hanga maitai
I roto i te ahumahi hanga maitai, ko te hiko hiko hiko (EAF) ko tetahi o nga tikanga tino whakamahia.Ko te whiriwhiri i te hiko kauwhata tika he mea nui mo tenei mahi.Ko nga hiko graphite RP (Regular Power) he whiriwhiri rongonui na te utu me te pai mo nga mahi oumu reo-hiko.
I te wa e whiriwhiri ana i nga hiko graphite RP, he maha nga mea nui hei whakaaro.Ko tetahi ko te diameter o te electrode, e tika ana mo te rahi o te oumu me nga whakaritenga whakaputa.Ko te karaehe o te hikohiko tetahi atu take;Ko nga hiko graphite RP te nuinga ka whakarōpūhia ki nga reanga e wha i runga i o raatau aukati hiko me te kaha flexible.Me whiriwhiri te auroro tika i runga i nga whakaritenga motuhake o te mahi oumu.

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.
