RP GRAPHITE Electrode – He pai te kawe hiko, he iti te whakapaunga
WHAKAMĀRAMA
Ko ngā irahiko karāpeti RP, e kiia nei ko ngā pou karāpeti i whakairohia, ka whakamahia hei rauemi kawe hiko pāmahana teitei mō ngā oumu pewa hiko. Ko ngā irahiko karāpeti mana noa kua tohua me te kiato iahiko e whakaaetia ana i raro i te 17 A/cm2. Ko te kounga o te irahiko karāpeti te mea e whakatau ana i te hua me te utu o te hanga maitai EAF.
Hei kaihanga, ka whakaratohia hoki e mātou ngā hiko karāhe UHP me ngā hiko karāhe HP mō ngā oumu pewa hiko tino kaha, tino kaha rānei. Haunga te whakamahinga i roto i ngā oumu pewa, ka whakamahia whānuitia hoki ngā hiko karāhe i roto i ngā oumu pewa ruku me ngā oumu koko.
ĀHUATANGA
Te kaha kawe iahiko teitei.
Te ātete tino pai ki te pakaru.
He ātete teitei ki te waikura me te ru wera.
He pai te pumau o ngā āhuatanga, kāore e ngāwari te whakapēkē.
He kaha ā-mīhini teitei, he ātete hiko iti.
He tino tika te mahi miihini, he pai te whakaotinga o te mata.
TONO
E whakamahia whānuitia ana ngā irahiko graphite mō te hanga maitai koranu, te konganuku me ētahi atu rauemi kore-konganuku.
