Izinto ezisetshenziswa kakhulu ekukhiqizweni kwe-graphite electrode yi-calcined petroleum coke. Ngakho-ke hlobo luni lwe-calcined petroleum coke olufanele ukukhiqizwa kwe-graphite electrode?
1. Ukulungiswa kwe-coking oil eluhlaza kufanele kuhlangabezane nomgomo wokukhiqiza i-petroleum coke esezingeni eliphezulu, futhi ukulebula i-petroleum coke esezingeni eliphezulu kufanele kube nesakhiwo esine-fiber. Umkhuba wokukhiqiza ubonisa ukuthi ukwengeza i-coke ye-thermal cracking residue engu-20-30% ku-coking oil eluhlaza kunekhwalithi engcono, engahlangabezana nezidingo zokukhiqiza ze-graphite electrode.
2. Amandla anele esakhiwo.
Ububanzi bezinto zokusetshenziswa ngaphambi kokuchoboza, ukuncibilika, isikhathi sokuchoboza ukunciphisa ukucolwa, kuhlangabezana nezidingo zokuhlanganisa ukwakheka kosayizi wesikwele wezinhlamvu.
3. Ukushintsha komthamo we-coke kufanele kube kuncane ngemva kokuphuka, okunganciphisa ukucindezeleka kwangaphakathi komkhiqizo okubangelwa ukuvuvukala komkhiqizo ocindezelwe kanye nokuncipha kwenqubo yokuthosa kanye ne-graphitization.
4. I-Coke kufanele ibe lula ukuyi-graphitization, imikhiqizo kufanele ibe nokumelana okuphansi, ukuqhuba okuphezulu kokushisa kanye ne-coefficient ephansi yokwanda kokushisa.
5. Ukuguquguquka kwe-coke kufanele kube ngaphansi kuka-1%,I-volatile matter ikhombisa ukujula kwe-coking futhi ithinta uchungechunge lwezakhiwo.
6. I-Coke kufanele ithosiwe ku-1300℃ amahora ama-5, futhi amandla ayo angempela angaphansi kuka-2.17g/cm2.
7. Okuqukethwe kwesulfure ku-coke akufanele kube ngaphezu kuka-0.5%.
INyakatho Melika kanye neNingizimu Melika yizona ezikhiqiza kakhulu i-petroleum coke emhlabeni, kuyilapho iYurophu izimele ngokwayo nge-petroleum coke. Abakhiqizi abakhulu be-petroleum coke e-Asia yiKuwait, Indonesia, Taiwan kanye neJapan kanye namanye amazwe nezifunda.
Kusukela ngawo-1990, ngentuthuko esheshayo yomnotho waseShayina, isidingo sikawoyela besilokhu sikhula unyaka nonyaka.
Uma inani lokucubungula uwoyela ongahluziwe landa kakhulu, inani elikhulu le-petroleum coke, umkhiqizo ophuma ekuhlanzeni uwoyela ongahluziwe, lizokhiqizwa ngokungenakugwenywa.
Ngokusho kokusatshalaliswa kwesifunda komkhiqizo we-petroleum coke eShayina, isifunda saseMpumalanga yeShayina sihamba phambili, sinomkhiqizo ongaphezu kuka-50% womkhiqizo ophelele we-petroleum coke eShayina.
Ilandelwa yisifunda esisenyakatho-mpumalanga kanye nesifunda esisenyakatho-ntshonalanga.
Okuqukethwe kwe-sulfur kwe-petroleum coke kudlala indima ebalulekile ekusetshenzisweni kwayo kanye nentengo yayo, futhi ukukhiqizwa kwe-graphitized petroleum coke kunqunyelwe yimithetho eqinile yezemvelo kwamanye amazwe, evimbela ukushiswa kwe-petroleum coke enokuqukethwe kwe-sulfur okuphezulu ezindaweni eziningi zokuhluza kanye nezitshalo zikagesi ezweni.
I-coke kaphethiloli yekhwalithi ephezulu ne-sulfur ephansi isetshenziswa kabanzi embonini yensimbi, i-aluminium kanye ne-carbon. Isidingo esikhulayo sandisa inani le-coke kaphethiloli izikhathi eziningana.
Eminyakeni yamuva nje, ukusetshenziswa okusobala kwe-petroleum coke eShayina kuyaqhubeka nokukhula ngesivinini esikhulu, futhi isidingo se-petroleum coke kuzo zonke izimakethe zabathengi siyaqhubeka nokukhula.
I-aluminium ibiza ngaphezu kwengxenye yenani eliphelele lokusetshenziswa kwe-petroleum coke eShayina. Isetshenziswa kakhulu ku-anode ebhakiwe kusengaphambili, futhi isidingo se-sulfur coke esiphakathi nesiphansi sikhulu.
Imikhiqizo yekhabhoni ifaka cishe ingxenye eyodwa kwezinhlanu zesidingo se-petroleum coke, esetshenziswa kakhulu ukulungisa ama-electrode e-graphite. Ama-electrode e-graphite athuthukile anenani eliphezulu futhi anenzuzo enkulu.
Ukusetshenziswa kukaphethiloli kubalelwa cishe kweshumi, kanti izimboni zikagesi, i-porcelain kanye nezimboni zengilazi zisebenzisa okuningi.
Isilinganiso sokusetshenziswa kwemboni yokuncibilikisa singu-1 - 20, ukusetshenziswa kwemishini yokugaya insimbi yokwenza insimbi.
Ngaphezu kwalokho, isidingo semboni ye-silicon naso siyinto ebalulekile okufanele icatshangelwe.
Ingxenye yokuthumela ngaphandle iyingxenye encane kakhulu, kodwa isidingo se-petroleum coke esezingeni eliphezulu emakethe yaphesheya sisafanele ukubhekelelwa. Kukhona nengxenye ethile ye-high-sulfur coke, kanye nokusetshenziswa kwekhaya.
Ngokuthuthuka komnotho waseShayina, izigayo zensimbi zasekhaya zaseShayina, izincibilikisi ze-aluminium kanye nezinye izinzuzo zomnotho zathuthuka kancane kancane, ukuze kwandiswe umkhiqizo kanye nekhwalithi yemikhiqizo, amabhizinisi amaningi amakhulu athenge kancane kancane i-graphenized petroleum coking carbonizer. Isidingo sasekhaya siyanda. Ngesikhathi esifanayo, ngenxa yezindleko zokusebenza eziphakeme, imali enkulu yokutshalwa kwezimali kanye nezidingo zobuchwepheshe eziphezulu ekukhiqizweni kwe-graphitized petroleum coke, azikho izinkampani eziningi zokukhiqiza kanye nengcindezi encane yokuncintisana okwamanje, ngakho-ke uma sikhuluma nje, imakethe inkulu, ukunikezwa kuncane, futhi ukunikezwa sekukonke kuncane kakhulu kunesidingo.
Okwamanje, isimo semakethe ye-coke kaphethiloli yaseShayina siwukuthi, imikhiqizo ye-coke kaphethiloli enesibabule esiningi isetshenziswa kakhulu njengophethiloli; imikhiqizo ye-coke kaphethiloli enesibabule esincane isetshenziswa kakhulu ekukhiqizeni izinsimbi kanye nokuthumela kwamanye amazwe; imikhiqizo ye-coke kaphethiloli ethuthukisiwe idinga ukungeniswa kwamanye amazwe.
Inqubo yokubala i-coke ye-petroleum yangaphandle iqedwa endaweni yokuhluza, i-coke ye-petroleum ekhiqizwa yindawo yokuhluza ingena ngqo endaweni yokubala i-coke ukuze ihluze i-coke.
Njengoba kungekho thuluzi lokugaya i-calcium ezindaweni zokuhluza zasekhaya, i-petroleum coke ekhiqizwa izindawo zokuhluza ithengiswa ngentengo ephansi. Njengamanje, i-petroleum coke yaseShayina kanye ne-calcining yamalahle kwenziwa embonini yensimbi, njengesitshalo sekhabhoni, isitshalo se-aluminium, njll.
