Calcined coke bụ ụdị carburizer na mmanụ ala coke nke dị iche iche nkọwa.
Isi nkọwa nke ngwaahịa graphite bụ 150-￠1578 na ụdị ndị ọzọ. Ọ dị mkpa maka ụlọ ọrụ ígwè na ígwè, ụlọ ọrụ silicon polysilicon ụlọ ọrụ, ụlọ ọrụ emery, ụlọ ọrụ ihe ikuku na ngwaahịa ndị ọzọ.
1: Petroleum koke
Coke mmanụ ala bụ ngwaahịa mmanụ ala siri ike siri ike nke ojii ma ọ bụ isi awọ gbara ọchịchịrị nwere nnukwu ọla ma nwee oghere. Ọ bụ granular, kọlụm, ma ọ bụ agịga dị ka carbonaceous ihe nke nwere kristal graphite na-ahụ anya.
Coke mmanụ nwere hydrocarbons, 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sọlfọ, na ogige metal dị arọ.
Petroleum coke bụ ihe sitere na pyrolysis nke mmanụ dị ndụ na ngalaba coking na-egbu oge iji mepụta mmanụ ọkụ na oke okpomọkụ.
Nsonaazụ nke coke mmanụ ala bụ ihe dịka 25-30% nke mmanụ a na-amị mkpụrụ.
Uru calorific ya dị ala bụ ihe dịka 1.5-2 ugboro nke coal, ọdịnaya ash abụghị ihe karịrị 0.5%, ọdịnaya na-agbanwe agbanwe bụ ihe dịka 11%, àgwà ya dịkwa nso na anthracite.
2: Ụkpụrụ dị mma nke coke mmanụ ala egbutela oge na-ezo aka na coke nke a na-emepụta na-egbu oge, nke a makwaara dị ka coke nkịtị, enweghị ọkọlọtọ ## kwekọrọ.
Ka ọ dị ugbu a, ụlọ ọrụ mmepụta ụlọ na-emepụtakarị dịka ọkọlọtọ ụlọ ọrụ SH0527-92 nke ụlọ ọrụ China Petrochemical nke mbụ chepụtara.
A na-ekewa ọkọlọtọ ahụ dịka ọdịnaya sọlfọ nke coke mmanụ ala siri dị.
Nke 1 coke bụ adabara na-eme nkịtị ike graphite electrode na steelmaking ụlọ ọrụ, na-eji dị ka carbon maka aluminum refining.
Nke 2 coke na-eji maka electrode mado na graphite electrode mmepụta na electrolytic cell (ọkụ) na aluminum smelting ụlọ ọrụ.
A na-eji No. 3 coke na-emepụta silicon carbide (ihe na-egweri ihe) na calcium carbide (calcium carbide), yana ngwaahịa carbon ndị ọzọ, nakwa dị ka mmepụta nke anode blocks maka aluminum smelter na na-ewu nke carbon lining. brik ma ọ bụ ọkụ ala n'ime ọkụ ọkụ.
3: isi USES of petroleum coke
Isi USES nke mmanụ ala coke bụ anode na-ebu ụzọ bute na tapawa anode maka aluminom electrolytic, mmepụta carbon nke onye na-ahụ maka carbonizing, electrode graphite, silicon ụlọ ọrụ na-agbaze na mmanụ ọkụ, wdg.
Dabere na nhazi na ọdịdị nke coke mmanụ ala, ngwaahịa coke mmanụ nwere ike kewaa n'ime coke coke, sponge coke, projectile coke na powder coke:
(1) Coke dị ka agịga, nke nwere usoro agịga doro anya na udidi eriri, bụ nke a na-ejikarị dị ka electrode graphite dị elu na ultra-high graphite electrode na nchara.
N'ihi na coke agịga nwere ihe nrịbama dị mma chọrọ na ọdịnaya sọlfọ, ọdịnaya ash, ọdịnaya na-agbanwe agbanwe na ezigbo njupụta, enwere ihe pụrụ iche chọrọ na teknụzụ mmepụta na akụrụngwa nke coke agịga.
(2) Sponge coke, nke nwere mmeghachi omume kemịkalụ dị elu yana ọdịnaya adịghị ọcha dị ala, bụ nke a na-ejikarị na ụlọ ọrụ na-agbaze aluminum na ụlọ ọrụ carbon.
(3) Projectile coke ma ọ bụ okirikiri coke: ọ bụ okirikiri na udi na 0.6-30mm na dayameta. A na-emepụtakarị ya site na nnukwu sọlfọ na nnukwu asphaltene ma nwee ike iji ya mee ihe maka ike ọkụ, ciment na mmanụ ọkụ ndị ọzọ.
(4) Powder coke: a na-emepụta ya site na usoro coking nke mmiri na-eme ka ọ dị mma (dayameta: 0.1-0.4mm), ọdịnaya volatility dị elu na ọnụọgụ mgbasawanye ọkụ dị elu, n'ihi ya, a pụghị iji ya mee ihe ozugbo na nkwadebe electrode na ụlọ ọrụ carbon.
4: mmanụ ala coke
Mgbe graphite electrode maka steelmaking ma ọ bụ anode mado (na-agbaze electrode) maka aluminum na magnesium, iji mee ka mmanụ ala coke (coke) na-emezu ihe a chọrọ, na coke ga-calcined.
Okpomọkụ calcining na-adịkarị gburugburu 1300 ℃, ebumnuche ya bụ iwepụ naphthol coke volatilization dị ka o kwere mee.
N'ụzọ dị otú a, a pụrụ ibelata ọdịnaya hydrogen nke petroleum coke reproducts, a pụrụ imeziwanye ogo grafitization nke mmanụ ụgbọala coke, ike dị elu na okpomọkụ na-eguzogide okpomọkụ nke graphite electrode nwere ike ime ka ọ dịkwuo mma, na ike eletrik eletrik nke graphite electrode nwere ike ime ka mma. .
A na-ejikarị Calcining na-emepụta graphite electrode, carbon mado ngwaahịa, diamond ájá, nri-ọkwa site ụlọ ọrụ, metallurgical ụlọ ọrụ na calcium carbide, n'ime nke graphite electrode na-eji ọtụtụ ebe.
Enwere ike iji Coke na-enweghị akpụ akpụ ozugbo dị ka calcium carbide, silicon carbide na boron carbide dị ka ihe egweri.
Enwere ike iji ya ozugbo dị ka coke maka ụlọ ọrụ mgbawa ọkụ ọkụ ma ọ bụ ọkụ ọkụ na-ekpuchi brik carbon, nwekwara ike iji ya mee nkedo usoro kọmpat coke, wdg.
