Kwii-electrode yegraphiteukwenza intsimbi okanye i-anode paste ye-aluminium kunye ne-magnesium yokwenza (i-electrode enyibilikayo), ukwenzela ukuba i-petroleum coke (coke) ihlangabezane neemfuno, i-coke i-calcined.Ubushushu becalcination, i-petroleum coke volatiles zibhekwa njengezinto.

(1) Susa ukufuma kunye nomxholo oguquguqukayo kwimathiriyeli ekrwada

Umxholo oguquguqukayo wezinto eziphathekayo unokupheliswa ngokubala, ngaloo ndlela ukwandisa umxholo wekhabhoni osisigxina wezinto eziluhlaza.Amanzi kwizinto eziluhlaza apheliswa yi-calcination, ehambelana nokutyumza, ukucoca kunye nokusebenza kokugaya, ukuphucula ukusebenza kwe-adsorption ye-carbon raw materials kwi-binder, kunye nokuphucula umgangatho weemveliso.

(2) Ukuphucula ukuxinana kunye namandla oomatshini bemathiriyeli ekrwada

Emva kokuba i-calcined, i-carbon material iyancipha umthamo, inyuka ngobuninzi kunye namandla ngenxa yokupheliswa kwezinto eziguquguqukayo, kwaye ifumana ukuzinza okungcono kwe-thermal, ngaloo ndlela inciphisa i-shrinkage yesibini yeemveliso ngexesha lokubala.

(3) Ukuphucula ukuhanjiswa kwezinto eziluhlaza

Emva kokubala, i-volatiles iyasuswa, kwaye isakhiwo se-molecular sitshintsha, sinciphisa ukuxhatshazwa kombane kunye nokuphucula ukuhanjiswa kombane kwizinto eziluhlaza.Ngokuqhelekileyo, okukhona iqondo eliphezulu lokubala, kokukhona i-conductivity ye-calcined ingcono.

(4) Ukuphucula ukuxhathisa kwe-oxidation yezinto eziluhlaza

Emva kokubala, njengoko iqondo lokushisa lekhabhoni linyuka, ukungcola okufana ne-hydrogen, i-oksijini kunye nesulfure kuya kukhutshwa ngokulandelelana nge-pyrolysis kunye nenkqubo ye-polymerization, kwaye umsebenzi weekhemikhali uya kuncipha kwaye iimpawu zomzimba kunye neekhemikhali ziya kuzinza, ngaloo ndlela kuphuculwe i-oxidation. ukuxhathisa kwempahla ekrwada.

I-calcined char isetyenziswa ikakhulu kwimveliso yei-electrode yegraphite, iimveliso ze-carbon paste, i-carborundum, imboni ye-phosphorus yokutya, imboni ye-metallurgical kunye ne-calcium carbide, phakathi kwayo i-electrode ye-graphite isetyenziswa kakhulu.Kwaye i-coke ngaphandle kokutshisa ukutshisa ingasetyenziselwa ngokuthe ngqo kwi-calcium carbide njengeyona nto iphambili, ukuveliswa kwe-silicon carbide kunye ne-boron carbide njengezinto zokusila, kodwa kunye nenkqubo yokuphosa nge-coke eshinyeneyo kunye neminye imiba.
