Isifinyezo
1. Umbono ojwayelekile
Ukwenziwa kwe-graphitization: amandla okukhishwa maphakathi nonyaka ozayo
Izinto zokusetshenziswa: iminyaka emibili ezayo kulindeleke ukuthi ibe nokuguquguquka okukhulu
2. Umehluko kanye nokusetshenziswa kwe-coke yenaliti yamalahle kanye ne-coke yenaliti yamafutha:
Izinto zokusetshenziswa ezahlukene: udaka olusekelwe ku-oyela, i-asphalt yamalahle esekelwe kumalahle.
Izicelo ezahlukene: i-coke yenaliti kawoyela, i-coke yenaliti yamalahle esetshenziselwa i-electrode enamandla aphezulu (ultra); i-coke yenaliti kawoyela ephekiwe eluhlaza nephekiwe ye-electrode engemihle.
Isiqondiso sentuthuko: Uchungechunge lwamalahle lungakhula esikhathini esizayo.
3. Iphethini yokuphakelwa kanye nesidingo se-petroleum coke: iziqondiso ezintathu zokusetshenziswa kwe-electrode engezansi + i-anode ebhakiwe kusengaphambili + i-electrode engemihle konke kuyakhula, kuyilapho uhlangothi lokuphakelwa lungandisi ukukhiqizwa noma ngisho nokunciphisa inani, okuholela emananini aphezulu futhi imikhiqizo engenisiwe ingase ingakwazi ukuhlangabezana nesidingo.
4. Ukwandiswa kwesitshalo se-Anode phezulu komfula: I-Zhongke Electric kanye ne-Anqing Petrochemical basayine ukubambisana okunesu, kodwa akukho ukuhlanganyela kwangempela kwamasheya noma ukutshalwa kwezimali.
5. Isilinganiso se-coke esingesihle: i-high-end ene-needle coke emsulwa, ixutshwe esiphelweni esiphakathi, i-low-end ene-petroleum coke emsulwa. I-Needle coke 30-40%, i-petroleum coke 60-70%. Ithani le-electrode engesihle ene-petroleum coke emsulwa 1.6-1.7 amathani.
6. Ukwenziwa kwe-graphitization okuqhubekayo: intuthuko yamanje ayifaneleki, ifana nemboni ye-diaphragm, kodwa futhi incike emishinini ukuze isinde, impumelelo yesikhathi esizayo inganciphisa ukusetshenziswa kwamandla kanye nezinsuku zokuthunyelwa.
