Calcined coke ke mofuta oa carburizer le petroleum coke ea litlhaloso tse fapaneng.
Litlhaloso tsa mantlha tsa lihlahisoa tsa graphite ke ￠150-￠1578 le mefuta e meng. E bohlokoa bakeng sa likhoebo tsa tšepe le tšepe, likhoebo tsa silicon polysilicon ea indasteri, likhoebo tsa emery, indasteri ea thepa ea sefofane le lihlahisoa tse ling.
1: Coke ea peterole
Petroleum coke ke sehlahiswa sa petroleum se setsho kapa se boputswa bo lefifi se nang le mmala wa metallic luster mme se na le masoba. Ke ntho e kang granular, columnar, kapa nale-like carbonaceous material e nang le likristale tse nyenyane tsa graphite.
Petroleum coke e na le li-hydrocarbons, 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sulfur, le metsoako ea heavy metal.
Petroleum coke ke sehlahisoa sa pyrolysis ea oli e tala sebakeng se liehang sa coking ho hlahisa oli e bobebe ka mocheso o phahameng.
Phello ea petroleum coke ke hoo e ka bang 25-30% ea oli e tala.
Khalori ea eona e tlaase ea lik'halori e ka ba makhetlo a 1.5-2 a mashala, molora oa molora ha o na ho feta 0.5%, litaba tse sa tsitsang ke hoo e ka bang 11%, 'me boleng ba eona bo haufi le anthracite.
2: Tekanyetso ea boleng ba petroleum coke Ho lieha ha petroleum coke ho bolela coke e hlahisoang ke yuniti e liehang ea ho pheha, e tsejoang hape e le coke e tloaelehileng, ha ho na ## standard e lumellanang.
Hajoale, likhoebo tsa tlhahiso ea malapeng li hlahisa haholo ho latela maemo a indasteri SH0527-92 a entsoeng ke China Petrochemical Corporation ea mehleng.
Tekanyetso e arotsoe haholo ho latela sebabole sa coke ea petroleum.
No. 1 coke e loketse ho etsa motlakase o tloaelehileng oa graphite electrode indastering ea ho etsa tšepe, hape e sebelisoa e le carbon bakeng sa ho hloekisa aluminium.
No. 2 coke e sebelisetsoa ho peista electrode le tlhahiso ea graphite electrode ka seleng ea electrolytic (sebōpi) indastering ea ho qhibilihisa aluminium.
No. 3 coke e sebelisoa ka tlhahiso ea silicon carbide (sila lintho tse bonahalang) le khalsiamo carbide (calcium carbide), hammoho le lihlahisoa tse ling tsa carbon, hammoho le tlhahiso ea diboloko anode bakeng sa smelter aluminium le kaho ea carbon lesela litene kapa sebōpi tlase ka sebōpi se phatlohang.
3: LITŠEBELETSO tse ka sehloohong tsa petroleum coke
Lisebelisoa tse ka sehloohong tsa petroleum coke ke anode le anode peista e phehiloeng pele bakeng sa aluminium ea electrolytic, tlhahiso ea carbon ea carbonizing agent, electrode ea graphite, silicon e qhibilihisang indasteri le mafura, joalo-joalo.
Ho ea ka sebopeho le ponahalo ea petroleum coke, lihlahisoa tsa petroleum coke li ka aroloa ka nale coke, sponge coke, projectile coke le powder coke:
(1) Coke e bōpehileng joaloka nale, e nang le sebopeho se hlakileng sa nale le sebopeho sa fiber, e sebelisoa haholo-holo e le electrode ea graphite ea matla a phahameng le electrode ea graphite e phahameng ka ho fetisisa ha ho etsoa tšepe.
Hobane coke ea nale e na le litlhoko tse tiileng tsa index ea boleng ka har'a sebabole, litaba tsa molora, litaba tse feto-fetohang le letsoalo la 'nete, ho na le litlhoko tse ikhethang ho theknoloji ea tlhahiso le lisebelisoa tse tala tsa nale coke.
(2) Coke ea seponche, e nang le lik'hemik'hale tse phahameng tsa lik'hemik'hale le lintho tse fokolang tse sa hloekang, e sebelisoa haholo indastering ea ho qhibilihisa aluminium le indasteri ea carbon.
(3) Projectile coke kapa spherical coke: e sebopeho sa spherical le bophara ba 0.6-30mm. Ka kakaretso e hlahisoa ho tloha masala a phahameng a sebabole le asphaltene 'me e ka sebelisoa feela bakeng sa ho hlahisa matla, samente le mafura a mang a indasteri.
(4) Powder coke: e hlahisoa ke mokhoa oa ho pheha metsi o nang le likaroloana tse ntle (bophara: 0.1-0.4mm), lihlahisoa tse phahameng tsa volatilization le coefficient e phahameng ea ho atolosa mocheso, kahoo e ke ke ea sebelisoa ka ho toba ho lokisetsa li-electrode le indasteri ea carbon.
4: Calcined petroleum coke
Ha graphite electrode bakeng sa steelmaking kapa anode peista (melting electrode) bakeng sa aluminium le magnesium, e le ho etsa petroleum coke (coke) kopana ditlhoko, coke lokela ho calcined.
Thempereichara ea calcining hangata e pota-potile 1300 ℃, sepheo sa eona e leng ho tlosa naphthol coke volatilization kamoo ho ka khonehang.
Ka tsela ena, lihlahisoa tsa hydrogen tsa lihlahisoa tsa petroleum coke li ka fokotsoa, tekanyo ea graphitization ea coke ea petroleum e ka ntlafatsoa, matla a mocheso o phahameng le ho hanyetsa mocheso oa electrode ea graphite e ka ntlafatsoa, 'me motlakase oa motlakase oa graphite electrode o ka ntlafatsoa.
Calcining e sebelisoa haholo-holo ho hlahisa electrode ea graphite, lihlahisoa tsa carbon paste, lehlabathe la Diamond, indasteri ea phosphorus ea lijo, indasteri ea metallurgic le calcium carbide, eo har'a eona e sebelisoang haholo ke graphite electrode.
Coke ntle le forging e ka sebelisoa ka kotloloho e le calcium carbide, silicon carbide le boron carbide joalo ka lisebelisoa tsa ho sila.
E ka boela ea sebelisoa ka kotloloho e le coke bakeng sa sebōpi sa metallurgical blast sebōpi kapa sebōpi se chesang sebōpi sa carbon setene, hape se ka sebelisoa bakeng sa ho lahla compact coke, joalo-joalo.
