FAAMANATU: Soʻo se manaʻoga faʻapitoa ile fua e mafai ona ofoina.
Fa'aaoga lautele i Alamanuia
- Mo le ogaumu faaeletise uamea faia
- Mo ogaumu phosphorus samasama
- Fa'aoga i le ogaumu fa'a'umu fa'ameamea po'o le kopa liusuavai.
- Fa'aoga e fa'amama le sila i totonu o ogaumu ladle ma isi faiga fa'ameamea
Auala e Filifilia ai le Electrode Graphite talafeagai
A oʻo mai i le filifilia o le graphite electrode saʻo, e tele mea e tatau ona mafaufau i ai.
- Muamua, e taua tele le lelei o le electrode. O se eletise maualuga maualuga o le ai ai se fausaga e sili atu ona tutusa, o lona uiga e itiiti le faʻalavelave i le gau ma le faʻafefe.
- Lona lua, o le tele o le eletise e tatau ona filifilia e faʻatatau i le EAF's power rating, faʻatasi ai ma ogaumu tetele e manaʻomia ai eletise tetele.
- Lona tolu, o le ituaiga electrode e tatau ona filifilia e faavae i luga o le sila uʻamea, faʻaogaina faʻasologa, ma le ogaumu mamanu. Mo se faʻataʻitaʻiga, o le eletise UHP (Ultra High Power) e sili atu ona fetaui i ogaumu maualuga, ae o le HP (High Power) electrode e talafeagai mo ogaumu feololo.
