Ọ bụghị naanị maka "ịgbakwunye carbon": Kedu ka coke petroleum graphitized si eme ka "mkpụrụ ndụ ihe nketa" nke ígwè dịkwuo mma n'ụzọ dị nro?

Coke mmanụ a kpụrụ akpụ na-eme ka "mkpụrụ ndụ ihe nketa" nke ígwè dịkwuo mma site n'ịhazi nhazi carbon, ịchịkwa nhazi ya nke ọma, imeziwanye arụmọrụ metallurgical, na imezu ihe achọrọ nke mmepụta dị elu. Usoro na mmetụta ndị a kapịrị ọnụ bụ ndị a:

I. Ime ka usoro kabọn ka mma: Mbulita dị mma site na "Ọka Nkịtị" gaa na "Osikapa A Na-eme Ka Ọ Dị Mma"

Ihe mgbakwunye carbon nkịtị (dịka coke calcined) nwere nhazi atọm carbon na-adịghị mma, nke nwere naanị 60%. N'ụzọ dị iche, coke petroleum graphitized, nke a na-enye ọgwụgwọ okpomọkụ dị elu na 2800℃, na-emepụta nhazi graphite nkịtị dị ka "kaadị egwuregwu a gbanyere agbakọ." Nhazi a na-enye ya ohere ịgbaze ngwa ngwa na ígwè agbaze agbaze, ebe ọnụego nnabata na-arị elu karịa 90%. Dịka ọmụmaatụ, mgbe a na-agbaze ígwè na-agbaze agbaze (GCr15), a ga-achịkwa ọdịnaya carbon kpọmkwem n'ime oke nke 1.05%-1.15%. Iji ihe mgbakwunye carbon graphitized na-eme ka ọnụego nnabata kwụsiri ike nke 92%, yana mgbanwe ọdịnaya carbon agaghị agafe ±0.02%, si otú a gbochie mgbawa gbajiri agbaji ma ọ bụ ike na-ezughị oke nke bearings nke mgbanwe ọdịnaya carbon kpatara.

II. Iwu Nhazi Kpọmkwem: Ịhazi "Atụmatụ Nri" maka ígwè dị elu

• Ọdịnaya Dị Ala: Usoro nhazi eserese na-agbanwe sọlfọ, nitrogen, na ihe ndị ọzọ na-adịghị ọcha ka ha bụrụ gas ndị na-emebi emebi, na-ebelata ọdịnaya sọlfọ ka ọ dị n'okpuru 0.05% na ọdịnaya nitrogen ka ọ dị n'okpuru 0.01%. Dịka ọmụmaatụ, ígwè silikọn na-abụghị nke a na-eji eme ihe n'ime ụlọ ọhụrụ nke ụgbọala ike chọrọ ọdịnaya carbon dị n'okpuru 0.005%, nke chọrọ iji ihe mgbakwunye carbon graphitized dị elu. N'otu aka ahụ, alloys dabere na nickel maka ndị na-ekupụ ike nuklia ga-enwerịrị ọdịnaya nitrogen nke na-agaghị agafe 0.01%, ihe achọrọ nke ihe mgbakwunye carbon nkịtị na-agaghị emezu.
• Njikwa Nhazi Dị Nkwụsi Ike: Site n'ịgbanwe ọnụọgụ nri na paramita usoro, enwere ike ijikwa ọdịnaya nke ihe dị ka carbon, sulfur, na nitrogen n'ime ígwè agbazere agbaze nke ọma. Dịka ọmụmaatụ, na agbaze ọkụ eletrik, a na-agbakwunye coke petroleum graphitized yana ígwè a kpara akpa na ihe ndị ọzọ a na-ebu iji zere oke oxidation nke nri buru ibu kpatara, na-ahụ na ọdịnaya carbon nke ihe a na-eme ka ọ dị mma.

Atọ. Imeziwanye Ọrụ Metallurgical: Site na "Inweta Nri" ruo "Ịnara Nri nke Ọma"

• Mmụba nke Ọbara Carbon: Ọkwa mmịpụta carbon nke coke petroleum graphitized karịrị 30% karịa nke ihe mgbakwunye carbon nkịtị, nke pụtara na maka 10 jin nke carbon etinyere, mmịpụta dị irè na-abawanye site na 3 jin. Nke a na-ebelata mfu carbon nke ukwuu n'oge usoro ígwè ma na-ebelata ọnụ ahịa mmepụta.
• Mbelata Mmetọ: Ọdịdị sọlfọ na nitrogen dị ala nke kọke petroleum graphitized na-ebelata mwepụta nke sọlfọ dioxide na nitrogen oxides n'oge a na-agbaze, na-agbaso ihe achọrọ maka nchekwa ike na mbelata mwepụta. Dịka ọmụmaatụ, iji kọke petroleum graphitized nwere ike ibelata mwepụta sọlfọ oxide na ụlọ ọrụ ígwè karịa 50%.

IV. Imezu ihe achọrọ maka mmepụta dị elu: Mbuli elu site na "Ụlọ Ike ígwè" gaa na "Ike Ike ígwè"

• Ịkwado Mmepụta Ngwaahịa Dị Elu: Coke mmanụ petroleum a na-ese n'elu bụ ihe dị mkpa maka imepụta ígwè agba isi awọ siri ike, ígwè silicon na-anaghị adabere na ya, alloys dabere na nickel, na ngwaahịa ígwè ndị ọzọ dị elu. Dịka ọmụmaatụ, imepụta ngwaahịa "hardcore" dịka flanges ikuku turbine na pipelines ike nuklia na-adabere na ịdị ọcha ya dị elu na njirimara ọsọ nnabata dị elu.
• Ịkwalite Mmelite Ụlọ Ọrụ: Ka ụlọ ọrụ ígwè nke China na-agbanwe gaa na mmepe dị elu na nke akwụkwọ ndụ akwụkwọ ndụ, "ndochi ụlọ" nke coke petroleum graphitized na-agba ọsọ. Ngwa ya abụghị naanị na ọ na-eme ka ngwaahịa ígwè dịkwuo mma kamakwa ọ na-akwalite ọganihu teknụzụ n'ofe usoro ụlọ ọrụ niile. Dịka ọmụmaatụ, ụlọ ọrụ ígwè belatara oke mgbanwe ọdịnaya carbon nke ígwè na-ebu site na ±0.05% ruo ±0.02% site na iji coke petroleum graphitized, nke butere mmụba 15% na ọnụego asambodo ngwaahịa.

V. Ọmụmụ Ihe Ikpe: Mmetụta "siri ike" nke Coke Mmanụ E Ji Graphitized

• Mmepụta ígwè Bearing: Mgbe ha jiri coke petroleum graphitized mee ihe, otu ụlọ ọrụ belatara oke mgbanwe ọdịnaya carbon nke ígwè bearing site na ±0.05% ruo ±0.02%, mụbaa ọnụego asambodo ngwaahịa site na 15%, ma chekwaa ihe karịrị nde yuan iri na mfu mkpofu kwa afọ.
• Ụlọ Mmanya Ụgbọala Ike Ọhụrụ: Site na iji coke petroleum graphitized dị ọcha nke nwere ọtụtụ ihe dị n'ime ya, ọdịnaya carbon nke ígwè silicon na-abụghị nke na-adabere na ya kwụsiri ike n'okpuru 0.005%, na-eme ka arụmọrụ moto dịkwuo mma site na 3% ma na-amụba oke ịnya ụgbọala site na 5%.
• Ihe na-eme ka ikuku jupụta n'ike nuklia: A chịkwara ọdịnaya nitrogen dị na alloys dabere na nickel n'okpuru 0.01%, na-egbochi mmebi ihe nke oke nitrogen kpatara ma na-agbatị ndụ ọrụ nke akụrụngwa site na afọ 20.
