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 sehlahisoa sa petroleum e ntšo kapa e bohlooho bo lefifi e nang le tšepe e khanyang 'me e 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 ha ho etsoa silicon carbide (sila) le calcium carbide (calcium carbide), hammoho le lihlahisoa tse ling tsa carbon, hammoho le tlhahiso ea li-anode blocks bakeng sa smelter ea aluminium le kahong ea lesela la carbon. litene kapa sebopi se ka tlase seboping sa mollo.
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 haedrojene tsa lihlahisoa tsa petroleum coke li ka fokotseha, tekanyo ea graphitization ea petroleum coke 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.
