Me pehea te Whakaorite i te Graphite Electrode me te Umu Arc Hiko
Ko nga hiko kauwhata he waahanga nui i roto i te mahi hanga rino i te Umu Arc Hiko (EAF).Heoi, ko te utu o te mahi hanga maitai e pa ana ki te waikura electrode, sublimation, dissolution, spalling, me te pakaru.Ko te rongo pai ko te kowhiringa hiko o te kauwhata, te whakamahi, me te tiaki ka taea te whakaiti i te kohi hiko.I roto i tenei tuhinga, ka matapakihia me pehea te whiriwhiri i te hiko graphite tika me pehea te pupuri tika kia whai hua ai to haumi.
Whakatakotoranga
Whakataurite i waenga i te kaha o te oumu hiko, te kawenga hiko whakawhiti me te rahi o te hiko.

Tohutohu Mo te Whakawhiwhia me te Whakamahi
- 1.Tangohia te taupoki whakamarumaru o te poka hiko hou, tirohia mehemea kua oti te miro i roto i te poka hiko me te kore e oti te miro, whakapiri atu ki nga miihini ngaio ki te whakatau mehemea ka taea te whakamahi i te hiko;
- 2.Purihia te iri hiko ki roto i te poka hiko i tetahi pito, ka waiho te urunga ngohengohe ki raro i tetahi atu pito o te hiko kia kore ai e pakaru te hononga hiko;(tirohia te pikitia1)
- 3.Whakamahia te hau pupuhi ki te pupuhi i te puehu me nga mea i runga i te mata me te poka o te hiko hono, katahi ka horoi i te mata me te hono o te hiko hou, horoia ki te paraihe;(tirohia te pikitia2)
- 4. Whakaarahia te hiko hou ki runga ake i te hiko e tarewa ana ki te hono ki te kohao hiko ka taka puhoi;
- 5.Whakamahia he uara taipana tika ki te maukati tika i te hiko;(tirohia te pikitia3)
- 6.Me waiho te kaipupuri rawhi ki waho o te raina whakaoho.(tirohia te pikitia4)
- 7.I roto i te wa whakamahine, he mea ngawari ki te hanga i te hiko kia angiangi me te pakaru, ka hinga nga hononga, te whakanui i te kai hiko, kaua e whakamahi i nga hiko ki te whakanui i te ihirangi waro.
- 8.Na te rereke o nga rauemi mata e whakamahia ana e ia kaihanga me te tukanga hangahanga, nga ahuatanga o te tinana me te matū o nga hiko me nga hononga o ia kaihanga.Na kei te whakamahia, i raro i nga ahuatanga whanui, Tena koa kaua e whakauru i nga hikohiko me nga hononga i hangaia e nga kaihanga rereke.
