Graphite Electrode Factors I le Umea
I totonu o le uʻamea, o le Eletise Arc Furnace (EAF) o se tasi lea o auala sili ona faʻaaogaina.Filifilia sa'o graphite electrode e taua mo lenei faagasologa.RP (Regular Power) graphite electrodes o se filifiliga lauiloa ona o lo latou gafatia ma talafeagai mo le faʻaogaina o le ogaumu feololo.
A filifilia RP graphite electrodes, e tele mea taua e mafaufau i ai.O le tasi o le electrode's diameter, lea e tatau ona fetaui mo le tele o le ogaumu ma le gaosiga o manaʻoga.O le togi o le electrode o se isi itu;RP graphite electrodes e masani lava ona faavasegaina i ni togi se fa e tusa ai ma lo latou tetee eletise ma le malosi flexural.O le togi talafeagai e tatau ona filifilia e faʻatatau i manaʻoga faʻapitoa o le faʻaogaina o le ogaumu.
