Fa'afefea ona Fa'afetaui le graphite Electrode ma le ogaumu fa'aeletise
graphite electrodes o vaega taua i le Eletise Arc ogaumu (EAF) faiga uamea. Ae ui i lea, o le tau o le faʻagasologa o le uʻamea e aʻafia e le electrode oxidation, sublimation, dissolution, spalling, ma le gau. O le tala lelei o le filifilia o le eletise graphite, faʻaogaina, ma le tausiga e mafai ona faʻaitiitia lelei le faʻaaogaina o le eletise. I totonu o lenei tusiga, o le a tatou talanoaina pe faʻapefea ona filifili le graphite electrode saʻo ma pe faʻafefea ona tausia lelei ina ia maua ai le tele o lau tupe teufaafaigaluega.
Fa'amatalaga
Fa'afetaui i le va o le ogaumu eletise, uta eletise ma le tele o le eletise.

Fa'atonuga mo Tu'ulima ma Fa'aaoga
- 1. Aveese le ufiufi puipui o le pu eletise fou, siaki pe ua maeʻa le filo i totonu o le pu eletise ma le filo e le atoatoa, faʻafesoʻotaʻi inisinia faʻapolofesa e fuafua pe mafai ona faʻaogaina le eletise;
- 2. Fa'ailo le mea fa'apipi'i eletise i totonu o le pu o le electrode i le tasi pito, ma tu'u le aluga vaivai i lalo o le isi pito o le eletise e aloese ai mai le fa'aleagaina o le so'oga eletise; (silasila i le ata 1)
- 3. Faʻaaoga le ea faʻapipiʻi e feula ai le pefu ma mea eseese i luga ma le pu o le eletise fesoʻotaʻi, ona faʻamama lea o le pito i luga ma le fesoʻotaʻiga o le eletise fou, faʻamama i se pulumu; (silasila i le ata 2)
- 4. Sii i luga le eletise fou i luga aʻe o le eletise o loʻo faʻatali e fetaui ma le pu eletise ma paʻu malie;
- 5. Fa'aaoga se tau torque talafeagai e loka lelei electrode; (silasila i le ata3)
- 6. E tatau ona tu'u le fa'amauina mai le laina fa'ailo. (silasila i le ata4)
- 7. I le taimi faʻamamaina, e faigofie ona fai le eletise manifinifi ma mafua ai le malepelepe, paʻu faʻatasi, faʻateleina le faʻaogaina o le eletise, faʻamolemole aua le faʻaogaina eletise e faʻatupu ai le carbon content.
- 8. Ona o le eseese o mea mataʻina o loʻo faʻaaogaina e taʻitasi taʻitasi ma le gaosiga o gaosiga, o mea faʻaletino ma vailaʻau o eletise ma sooga o taʻitasi taʻitasi. O lea i le faʻaaogaina, i lalo o tulaga lautele, Faamolemole aua neʻi faʻafefiloi faʻaogaina eletise ma soʻoga na gaosia e tagata gaosi oloa eseese.
