Lisebelisoa tsa li-recarburizer tse fapaneng
Carburizer ke lisebelisoa tsa lik'hemik'hale tse ka ntlafatsang ka katleho phello ea carbonization ea thepa le tikoloho ea metallurgic.Ho na le li-carburizer tse ngata tse sebelisoang indastering ea tšepe le ea tšepe.Li-recarburizer tse fapaneng bakeng sa merero e fapaneng li na le litlamorao tse fapaneng.
1. Recarburizer ea maiketsetso ea graphite
Ntho e ka sehloohong e tala ea graphite ea maiketsetso ke phofo ea calcined petroleum coke, eo ho eona sekontiri (kapa pregelatinization e hloekileng) e kenngoa e le setlamo, 'me ho kenyelletsoa lisebelisoa tse ling tse thusang.Ka lisebelisoa tse sa tšoaneng tse tala, e hatelloa ebe e thehoa, ebe e sebetsoa ka sepakapaka se se nang oxidizing ho 2500-3000 ° C ho etsa hore e be graphitized.Ka mor'a phekolo e phahameng ea mocheso, litaba tsa molora, sebabole le khase li fokotsehile haholo.
Ka lebaka la theko e phahameng ea lihlahisoa tsa maiketsetso tsa graphite, boholo ba li-recarburizer tsa maiketsetso tse sebelisoang hangata li sebelisa lisebelisoa tse nchafalitsoeng joalo ka li-chips, li-electrode tsa litšila le li-block tsa graphite ha ho etsoa li-electrode tsa graphite libakeng tsa motheo ho fokotsa litšenyehelo tsa tlhahiso.Ha ho qhibiliha tšepe ea ductile, e le ho etsa hore boleng ba metallurgic ba tšepe e entsoeng ka tšepe bo phahametse, recarburizer e lokela ho ba graphite ea maiketsetso.
Tšebeliso ea graphite recarburizer: Graphite recarburizer e ka ntlafatsa sebopeho sa metallographic ea li-castings, ka potlako ea hlahisa motheo oa graphite ka tšepe e entsoeng ka tšepe, ea khutsufatsa nako ea carbonization, le ho ntlafatsa phello ea carbonization.
2. Petroleum coke recarburizer
Petroleum coke ke recarburizer e sebelisoang haholo, 'me petroleum coke ke sehlahisoa sa ho hloekisa oli e tala.Motsoako o setseng oa oli le petroleum o fumanoeng ka khatello ea khatello kapa vacuum distillation e ka sebelisoa e le lisebelisoa tse tala bakeng sa ho etsa petroleum coke, 'me coke ea petroleum e ka fumanoa ka mor'a ho pheha.Sehlahisoa sa coke e tala ea petroleum e ka tlase ho palo ea oli e tala, 'me boemo bo sa hloekang ba coke e tala ea petroleum bo phahame, kahoo e ke ke ea sebelisoa ka ho toba e le carburizer' me e tlameha ho calcined pele.Petroleum coke e tala e na le libopeho tsa spongy, nale, granular le mokelikeli.
Kopo ea petroleum coke recarburizer: Petroleum coke recarburizer e ka eketsa mocheso oa sebōpi ka katleho, e ke ke ea eketsa mocheso oa sebōpi feela, empa hape ea ntlafatsa lihlahisoa tsa metallurgical, ea ntlafatsa le ho ntlafatsa tikoloho e thata ea metallurgic.
3. Coke le Anthracite
Ts'ebetsong ea ho etsa tšepe ea tšepe ea arc, coke kapa anthracite e ka eketsoa e le recarburizer.Sebopi sa induction se qhibilihisa tšepe e entsoeng ka tšepe ha se hangata se sebelisoang e le recarburizer ka lebaka la molora oa sona o phahameng le litaba tse fetohang.Calciner e calcined ka anthracite, 'me mocheso oa calcination ke 1200-1300.Granular e ntšo, metallic luster, carbon 85-93 e tsitsitseng, sebabole se itekanetseng le nitrogen content.
Tšebeliso ea mashala a calcined recarburizer: Morero oa mashala a calcined recarburizer ke ho eketsa khabone hantle le ho khutsufatsa nako ea khabone.Tšebeliso ea mashala a calcined recarburizer e ka boloka nako hantle.
