Taupānga Whānui
RP graphite electrode Kei te nuinga whakamahia i roto i te LF (Umu Ladle) me te EAF (Electric Arc Furnace) hanga maitai.Ko te electrode he tino hototahi ki enei oumu me te whakarato hua pai.Kei te whakamahia hoki te hiko graphite RP ki etahi atu tono penei i te anode i mua i te tunua me te koko rino.
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.
