Inqubo yokukhiqiza kabusha i-Recarburizer nezinto zokusetshenziswa
I-recarburizer yinto ekhabhoni.Ama-carburizers ayengezwa ngesikhathi sokuncibilikiswa ukuze agcwalise i-carbon elahlekile ngesikhathi sokuncibilikiswa kwensimbi.Siyazi ukuthi kunezinhlobo eziningi zama-recarburizers, njenge-petroleum coke recarburizers, i-graphite recarburizer yokwenziwa, njll., ngakho-ke izinto zokusetshenziswa ezidingekayo zokubuyisela kabusha zihlukile, ngakho-ke yiziphi izinto zokusetshenziswa zama-recarburizers?Inqubo ye-recarburizers iyini?U-Xiaobian uzokutshela ngezinto ezingavuthiwe nezinqubo ezidingekayo ku-recarburizer.
Izinto ezingavuthiwe ezidingekayo kuma-recarburizers
Kunezinhlobo eziningi zezinto zokusetshenziswa zokwenziwa kabusha kwama-recarburizers, okuhlanganisa amalahle, ikhabhoni esekwe emalahleni, i-coke, i-graphite, i-petroleum coke eluhlaza, njll., okunezigaba eziningi ezincane nezigaba ezihlukahlukene.
Njengamanje, iningi lama-recarburizers emakethe, okuhlanganisa ama-electrode e-graphite, i-graphitized petroleum coke, njll., zisebenzisa i-petroleum coke eluhlaza.I-petroleum coke engahluziwe itholakala ngokugcotshwa kwamafutha ayinsalela kanye ne-petroleum pitch etholwe ngokugcotshwa kukawoyela ongahluziwe ngaphansi kwengcindezi yomoya noma i-vacuum.I-petroleum coke eluhlaza inokuqukethwe okuphezulu kokungcola futhi ayikwazi ukusetshenziswa ngokuqondile njengesithako kabusha.Kumele i-calcined noma i-graphitized.Ama-recarburizer ekhwalithi ephezulu ngokuvamile adinga i-graphitization.Ngaphansi kwezimo zokushisa eziphakeme, ukuhlelwa kwama-athomu ekhabhoni kusesimweni se-graphite encane, ngakho kubizwa ngokuthi i-graphitization.I-Graphitization inganciphisa okuqukethwe kokungcola ku-recarburizer, kwandise okuqukethwe kwekhabhoni ye-recarburizer, futhi kunciphise okuqukethwe kwesibabule.Ama-recarburizers asetshenziselwa ukuphonsa, okungakhuphula kakhulu inani lensimbi yensimbi, ukunciphisa inani lensimbi yengulube noma konga insimbi yengulube.
Inqubo ye-Carburizer
Ngenxa yezinhlobonhlobo zezinto zokusetshenziswa zama-recarburizers, izinqubo nazo zihlukile, kepha kukhona lezi zintathu ezilandelayo:
1. Ukubalwa
Izinto zokusetshenziswa ze-Carbonaceous zibalwa ekushiseni okuphezulu kwe-1200-1500 ° C lapho kungekho moya.Ukubala kubangela uchungechunge lwezinguquko esakhiweni nasezimpahleni ze-physicochemical zezinto ezihlukahlukene zokusetshenziswa.Kuyinqubo yokwelapha ukushisa kwe-recarburizer.Kokubili i-anthracite ne-petroleum coke iqukethe inani elithile lezinto eziguquguqukayo futhi idinga ukubalwa.Nokho, lapho i-petroleum coke ne-pitch coke ixutshwa futhi isetshenziswa ngaphambi kokubala, kufanele ithunyelwe kumshini wokubala ukuze ibalwe kanye ne-petroleum coke.
2. Ukugazinga
Ukushisa kuyinqubo yokwelapha ukushisa lapho ukudla okuluhlaza okucindezelwe kushiswa ngesilinganiso esithile sokushisa endaweni evikelayo esithandweni sokushisa ngaphansi kwesimo sokuhlukanisa umoya.
Inhloso yokosa wukuqeda ama-volatile.Ngokuvamile, izinhlobo ezingaba ngu-10 ze-volatile ziyakhishwa ngemva kokugazinga.Ngakho-ke, isivuno sokuthosa ngokuvamile singama-90;i-binder iyaphekwa, futhi umkhiqizo wosiwe ngokuvumelana nezimo ezithile zenqubo, ukuze i-binder iphekwe, futhi inethiwekhi ye-coke yakhiwe phakathi kwezinhlayiya zezinto eziluhlaza, ezihlanganisa ngokuqinile zonke izinto zokusetshenziswa ezinobukhulu obuhlukahlukene bezinhlayiyana ndawonye.Yenza imikhiqizo engu-# # ibe nezakhiwo ezithile zomzimba namakhemikhali.Ngaphansi kwezimo ezifanayo, izinga lokupheka liphakeme, ikhwalithi engcono kakhulu;esimweni sejometri ehleliwe, umkhiqizo uzothambisa futhi i-binder izofuduka ngesikhathi sokubhaka.Njengoba izinga lokushisa likhuphuka, kwakhiwa inethiwekhi yokupheka, eyenza umkhiqizo ube lukhuni.Ngakho-ke, ukuma kwayo akushintshi njengoba izinga lokushisa likhuphuka.
3. Extrusion
Inhloso yenqubo ye-extrusion ukwenza impahla eluhlaza idlule isikhunta somumo othile ngaphansi kwengcindezi, futhi ibe i-billet enomumo nobukhulu obuthile ngemva kokuhlanganiswa nokukhubazeka kwepulasitiki.I-extrusion ekubumbeni inqubo ngokuyinhloko inqubo deformation plastic of unama.Inqubo ye-extrusion yenzeka ekamelweni lezinto ezibonakalayo kanye nombhobho ogobile.Izinto ezishisayo ekamelweni ziphushwa i-plunger eyinhloko ngemuva.Ukususwa okuphoqelekile okuqhubekayo kwegesi ezintweni ezingavuthiwe, ukuminyanisa okuqhubekayo kokokusebenza, kanye nokunyakaza ngesikhathi esisodwa kwento eluhlaza ukuya phambili.Lapho impahla eluhlaza ihamba engxenyeni ye-cylindrical yegumbi lezinto ezibonakalayo, impahla eluhlaza ingabhekwa njengokugeleza okuzinzile, futhi ungqimba lwezinhlayiyana ngalunye luhamba ngokuhambisana.Lapho impahla eluhlaza ingena ku-extrusion nozzle futhi ine-deformation emise okwe-arc, impahla eluhlaza eseduze nodonga lombhobho izobhekana nokungqubuzana okukhulu njengoba ithuthuka, futhi ungqimba lwempahla luqala ukugoba.Impahla eluhlaza inejubane elihlukile lokuthuthuka, kanye nokuthuthuka kwempahla yangaphakathi.Ngakho-ke, ukuminyana komkhiqizo eduze kokuqondisa kwe-radial akufani, ngaleyo ndlela kukhiqiza ukucindezeleka kwangaphakathi okubangelwa amazinga okugeleza ahlukene ezendlalelo zangaphakathi nezingaphandle kubhulokhi ekhishwe.Ngemuva kokuthi unamathisele ungene engxenyeni eqondile ye-deformation, ikhishwa futhi yakheke.
Indlela ye-extrusion idinga ukungeza isibophezelo esiningi sokubumba, futhi okuqukethwe kwekhabhoni ngokuvamile akuhlangabezani nezidingo zama-recarburizer ekhwalithi ephezulu.Impushana yegraphite ecindezelwe, ngenxa yokuthi iyibhulokhi eqinile, ayinakho ukwakheka kwezimbotshana, ngakho-ke isivinini sokumunca kanye nezinga lokumunca alilungile njenge-recarburizers e-calcined kanye ne-calcined.
