I legraphite electrodemo le faia o uʻamea poʻo le anode faʻapipiʻi mo le alumini ma le magnesium (melting electrode), ina ia mafai ai ona faʻamalieina le suauʻu (coke) ma mea e manaʻomia, o le coke o loʻo calcined.O le vevela o le suau'u, suau'u coke volatiles ua manatu o mea taua.

(1) Aveese le susū ma mea fa'afefete mai mea mata

E mafai ona faʻaumatia mea faʻafefeteina o mea mataʻutia e ala i le calcination, ma faʻateleina ai le faʻamautu o le carbon content of raw material.O le vai i mea mata e faʻaumatia e ala i le calcination, lea e faʻaogaina i le tuʻimomomoina, suʻesuʻeina ma le faʻaogaina o gaioiga, faʻaleleia le faʻaogaina o le faʻaogaina o mea faʻapitoa carbon i le fusi, ma faʻaleleia le lelei o oloa.

(2) Faʻaleleia le mamafa ma le malosi faʻainisinia o mea mata

A maeʻa ona faʻapipiʻiina, e faʻaitiitia le mea o le carbon i le voluma, faʻateleina le mamafa ma le malosi ona o le faʻaumatiaina o volatiles, ma maua ai le faʻamautuina lelei o le vevela, ma faʻaitiitia ai le faʻaitiitia lona lua o oloa i le taimi o le calcination.

(3) Fa'aleleia le fa'aosoina o mea mata

A maeʻa le calcination, e aveesea volatiles, ma suia foi le fausaga mole, faʻaitiitia ai le faʻamalosia o le eletise ma faʻaleleia le eletise eletise o mea mata.I se tulaga lautele, o le maualuga o le tikeri o le calcination, o le sili atu lea o le conductivity o mea calcined.

(4) Faʻaleleia le faʻamaʻi faʻamaʻiina o mea mata

A maeʻa le faʻavasegaina, aʻo faʻatupulaʻia le vevela o mea faʻapitoa carbon, o mea leaga e pei o le hydrogen, okesene ma le sulfur o le a faʻasolosolo faʻasolosolo e ala i le pyrolysis ma le polymerization, ma o le a faʻaitiitia le gaioiga faʻainisinia ma o le a faʻamautu mea faʻaletino ma vailaʻau, ma faʻaleleia ai le faʻamaʻiina. tetee i mea mata.

Calcined char e masani ona faʻaaogaina i le gaosiga ographite electrode, oloa fa'apipi'i carbon, carborundum, alamanuia phosphorus mea'ai, alamanuia metallurgical ma calcium carbide, i totonu o le graphite electrode e sili ona faʻaaogaina.Ma o le coke e aunoa ma le susunuina o le afi e mafai foi ona faʻaaogaina saʻo mo le calcium carbide e avea ma mea autu, o le gaosiga o le silicon carbide ma le boron carbide e pei o le oloina o mea, ae faʻapea foʻi mo le tuʻuina o le faʻagasologa ma le mafiafia coke ma isi itu.
