Impahla eluhlaza eyinhloko esetshenziswa ekukhiqizeni i-graphite electrode i-calcined petroleum coke.Ngakho-ke hlobo luni lwe-coke ye-petroleum e-calcined efanelekile ukukhiqizwa kwe-graphite electrode?
1. Ukulungiswa kokupheka uwoyela oluhlaza kufanele kuhlangabezane nesimiso sokukhiqiza i-coke ye-petroleum yezinga eliphezulu, futhi ukulebula kwe-coke ye-petroleum yezinga eliphezulu kufanele kube nesakhiwo esine-fibrous eyengeziwe.Umkhuba wokukhiqiza ubonisa ukuthi ukungeza i-20-30% yensalela ye-coke eshisayo ekuphekeni uwoyela oluhlaza kunekhwalithi engcono, engahlangabezana nezidingo zokukhiqiza ze-graphite electrode.
2. Amandla anele esakhiwo.
Ububanzi bempahla eluhlaza ngaphambi kokuchotshozwa, ukuncibilika, isikhathi sokuchotshozwa ukuze kuncishiswe ukugoqa, kuhlangatshezwane nezidingo zokwakheka kosayizi wokusanhlamvu okuyisikwele.
3. Ukuguqulwa kwevolumu ye-coke kufanele kube kuncane ngemva kokuphuka, okunganciphisa ukucindezeleka kwangaphakathi kumkhiqizo obangelwa ukubuyisela emuva komkhiqizo ocindezelwe kanye nokuncipha kwenqubo yokugcoba kanye ne-graphitization.
4. I-Coke kufanele ibe lula ku-graphitization, imikhiqizo kufanele ibe nokuphikiswa okuphansi, i-conductivity ephezulu ye-thermal kanye ne-coefficient ephansi yokwandisa okushisayo.
5. I-coke volatilization kufanele ibe ngaphansi kuka-1%,Indaba eguquguqukayo ikhombisa ukujula kokupheka futhi ithinta uchungechunge lwezakhiwo.
6. I-coke kufanele yosiwe ku-1300℃ amahora angu-5, futhi amandla ayo adonsela phansi angempela akufanele abe ngaphansi kuka-2.17g/cm2.
7. Okuqukethwe kwesibabule ku-coke akufanele kube ngaphezu kuka-0.5%.
INyakatho Melika kanye neNingizimu Melika abakhiqizi abakhulu be-petroleum coke emhlabeni, Nakuba iYurophu ngokuyisisekelo ikwazi ukuzimela nge-petroleum coke.Abakhiqizi abakhulu be-petroleum coke e-Asia yi-Kuwait, i-Indonesia, i-Taiwan ne-Japan namanye amazwe nezifunda.
Kusukela ngeminyaka yawo-1990, ngokuthuthuka ngokushesha komnotho waseShayina, isidingo sikawoyela besilokhu sikhula unyaka nonyaka.
Lapho inani lokucutshungulwa kukawoyela ongahluziwe landa kakhulu, inani elikhulu le-petroleum coke, okuwumkhiqizo wokucwenga uwoyela ongahluziwe, nakanjani lizokhiqizwa.
Ngokusho kokusatshalaliswa kwesifunda kokuphuma kwe-petroleum coke e-China, isifunda sase-China esisempumalanga singesokuqala, sibala ngaphezu kuka-50% wesamba somkhiqizo we-petroleum coke e-China.
Ilandelwa yisifunda esisenyakatho-mpumalanga kanye nesifunda esisenyakatho-ntshonalanga.
Okuqukethwe kwesibabule se-petroleum coke kudlala indima ebalulekile ekusetshenzisweni kwayo nasentengo, futhi ukukhiqizwa kwe-coke ye-petroleum e-graphitized kunqunyelwe imithetho eqinile yezemvelo emazweni angaphandle, evimbela ukushiswa kwe-petroleum coke ene-sulfur ephezulu ezindaweni eziningi zokuhluza nasezitshalweni zamandla izwe.
Ikhwalithi ephezulu nephansi ye-sulphur petroleum coke isetshenziswa kakhulu ezimbonini zensimbi, i-aluminium kanye ne-carbon.Isidingo esikhulayo sinyusa inani le-petroleum coke izikhathi eziningana.
Eminyakeni yamuva nje, ukusetshenziswa okusobala kwe-petroleum coke e-China kuyaqhubeka kukhula ngesivinini esikhulu, futhi isidingo se-petroleum coke kuzo zonke izimakethe zabathengi silokhu sikhula.
I-Aluminium yenza ngaphezu kwesigamu sengqikithi yokusetshenziswa kwe-petroleum coke e-China.Isetshenziswa kakhulu ku-anode ephekwe ngaphambili, futhi isidingo se-coke yesulfure ephakathi nendawo nephansi sikhulu.
Imikhiqizo yekhabhoni yenza cishe ingxenye eyodwa kwezinhlanu yesidingo se-petroleum coke, esetshenziswa kakhulu ukulungisa ama-electrode e-graphite.Ama-electrode e-graphite athuthukile anenani eliphakeme futhi anenzuzo enkulu.
Ukusetshenziswa kukaphethiloli kubiza cishe ingxenye eyodwa kweshumi, kanti izimboni zikagesi, izimboni zobumba nezingilazi zisebenzisa okwengeziwe.
Isilinganiso sokusetshenziswa kwemboni yokuncibilika kokukodwa - kwamashumi amabili, ukusetshenziswa kokugaya insimbi yokwenza insimbi.
Ngaphezu kwalokho, isidingo semboni ye-silicon singamandla okufanele sibalwe nawo.
Ingxenye yokuthekelisa ibamba ingxenye encane kakhulu, kodwa isidingo sekhwalithi ephezulu ye-petroleum coke emakethe yaphesheya kusafanele sibhekwe ngabomvu.Kukhona nengxenye ethile ye-coke ephezulu-sulphur, kanye nokusetshenziswa kokusetshenziswa kwasekhaya.
Ngokuthuthuka komnotho waseShayina, izigayo zensimbi ezifuywayo zaseChina, izincibilikisi ze-aluminium nezinye izinzuzo zezomnotho ziye zaba ngcono kancane kancane, ukuze kwandiswe umkhiqizo kanye nekhwalithi yemikhiqizo, amabhizinisi amaningi amakhulu kancane kancane athenge i-graphenized petroleum coking carbonizer.Isidingo sasekhaya siyakhula. Ngesikhathi esifanayo, ngenxa yezindleko eziphezulu zokusebenza, imali enkulu yokutshala izimali kanye nezidingo eziphakeme zobuchwepheshe ekukhiqizeni i-coke ye-petroleum graphitized, awekho amabhizinisi amaningi okukhiqiza kanye nengcindezi encane yokuncintisana okwamanje, uma kuqhathaniswa, imakethe inkulu, ukunikezwa kuncane, futhi ukunikezwa sekukonke kucishe kube ngaphansi kunesidingo.
Njengamanje, isimo semakethe ye-petroleum coke yaseChina siwukuthi, imikhiqizo ye-coke ye-sulphur ephezulu ye-sulphur petroleum coke, ikakhulukazi esetshenziswa njengophethiloli;Imikhiqizo ye-coke ye-sulphur petroleum ephansi isetshenziswa ikakhulukazi kwezensimbi nokuthekelisa;Imikhiqizo ye-coke ka-petroleum ethuthukisiwe idinga ukungeniswa kwamanye amazwe.
Inqubo ye-petroleum coke calcination yangaphandle iqedwa endaweni yokucwenga, i-petroleum coke ekhiqizwa indawo yokuhluza ingena ngqo kuyunithi yokubala ukuze kubalwe.
Njengoba kungekho mshini wokubala ezindaweni zokuhlanza ezifuywayo, i-petroleum coke ekhiqizwa yizindawo zokuhlanza ithengiswa ngokushibhile.Okwamanje, i-petroleum coke yaseChina kanye ne-calcining yamalahle yenziwa embonini ye-metallurgical, njengesitshalo se-carbon, isitshalo se-aluminium, njll.
