1. Pono e akaretsang
Graphitization: bokhoni ba ho lokolla bohareng ba selemo se tlang
Lisebelisoa tse tala: lilemo tse peli tse latelang li lebeletsoe hore e be tse phahameng haholo
2. Phapang le ts'ebeliso ea coke ea nale ea mashala le coke ea nale ea oli:
Lisebelisoa tse fapaneng tse tala: oli - e thehiloeng oli e entsoeng ka oli, mashala - asphalt ea mashala.
Lisebelisoa tse fapaneng: coke ea nale ea oli, coke coke coke e sebelisetsoang (ultra) e phahameng ea motlakase; Oli nale coke e tala le phehiloe coke bakeng sa eleketrode negative.
Tataiso ea nts'etsopele: Letoto la mashala le ka hlaha nakong e tlang.
3. Phepelo le tlhokahalo ea mohlala oa petroleum coke: litsela tse tharo tsa kopo ea eleketrode e ka tlaase ho metsi + anode e phehiloeng esale pele + li-electrode tse mpe kaofela li ntse li eketseha, ha lehlakore la phepelo le sa atolose tlhahiso kapa hona ho fokotsa bongata, e leng se lebisang ho theko e phahameng le ho tsoa linaheng tse ling. lihlahisoa li kanna tsa se khone ho fihlela tlhoko.
4. Ho atolosoa ha semela sa Anode ho ea holimo: Zhongke Electric le Anqing Petrochemical li saenetse tšebelisano-'moho ea leano, empa ha ho na karolo ea sebele ea tekano kapa matsete.
5. Karo-karolelano e mpe ea coke: boemo bo phahameng bo nang le coke ea nale e hloekileng, e kopantsoeng qetellong e bohareng, e tlaase e nang le coke e hloekileng ea petroleum. Nale coke 30-40%, petroleum coke 60-70%. Lithane tsa electrode tse mpe tse nang le petroleum coke e hloekileng ea lithane tse 1.6-1.7.
6. graphitization e tsoelang pele: tsoelo-pele ea morao-rao ha e ntle, e tšoana le indasteri ea diaphragm, empa hape e itšetlehile ka lisebelisoa ho phela, katleho ea nakong e tlang e ka fokotsa tšebeliso ea matla le matsatsi a ho romelloa.
