Li-carburizer li arotsoe ka: li-carburizer tsa petroleum coke, li-graphite carburizers, li-graphite carburizers tsa tlhaho, li-metallurgical coke carburizers, li-calcined carburizers tsa mashala, li-carburizer tsa tlhaho tsa graphite, le li-carburizer tse entsoeng ka metsoako.

Phapang e kholo lipakeng tsa li-graphite recarburizer le li-recarburizer tsa mashala ke:

1. Thepa e tala e fapane.Graphite recarburizer e sebetsoa ka ho hlahloba graphite ea tlhaho, athe mashala recarburizer e calcined ho tsoa ho anthracite;

Ea bobeli, litšobotsi li fapane.Graphite recarburizer e na le melemo ea sebabole se tlase le naetrojene, ho hanyetsa mocheso o phahameng, conductivity e ntle ea motlakase, joalo-joalo, tse sa fumaneheng ka li-recarburizers tse thehiloeng ka mashala;

Boraro, sekhahla sa ho monya se fapane.Sekhahla sa ho kenngoa ha graphite recarburizer se ka fihla ho feta 90%, kahoo le haeba carbon content ea graphite recarburizer e se e phahameng, e ka finyella litlhoko tsa tšebeliso;

Ea bone, litšenyehelo li fapane.Leha theko ea graphite recarburizer e batla e phahame, litšenyehelo tse felletseng tsa ts'ebeliso li tlase haholo.

Carburization ea carburizer e etsoa ka ho qhibiliha le ho hasana ha carbon ka tšepe e qhibilihisitsoeng.Liphuputso li bontšitse hore ha carbon content ea tšepe-carbon alloy ke 2.1%, graphite recarburizers le non-graphite recarburizers sebetsa ka ho lekana ka lebaka la ho koloba 'meleng;empa ha khabone ea tšepe e qhibilihisitsoeng e feta 2.1%., Graphite ka graphite recarburizer e ka qhibiliha ka ho toba ka tšepe e qhibilihisitsoeng, 'me ketsahalo ena e ka bitsoa ho qhibiliha ka ho toba.Ketsahalo e tobileng ea ho qhibiliha ea non-graphite recarburizer ha e eo, empa khabone e ntse e qhalana butle-butle ebe e qhibiliha ka har'a tšepe e qhibilihisitsoeng ha nako e ntse e tsamaea.Ka hona, sekhahla sa carbonation sa graphite recarburizer se phahame haholo ho feta sa non-graphite recarburizer.

Lipotso tseo u lokelang ho li ela hloko ha u khetha carburant:

1. Leka ho sebelisa li-recarburizers tse nang le mocheso o phahameng oa mocheso (ha mocheso oa phekolo o phahame, o ntlafatsa phello ea graphitization), joalo ka li-electrode tsa graphite kapa coke ea oli ea graphitized.Hobane recarburizer e ntle e na le sekhahla se phahameng sa ho monya le lebelo la ho qhibiliha ka potlako, ho molemo ho fokotsa ts'ebeliso ea matla, 'me e ka eketsa ka nepo motheo oa nucleation ea tšepe e qhibilihisitsoeng le ho ntlafatsa boleng ba metallurgical;

2. Khetha li-carburizer tse nang le likarolo tse tlase tsa litšila tse kang sebabole le naetrojene.Tekanyo ea nitrogen ea recarburizer e nang le sebabole se phahameng le eona e phahame.Ha karolo ea naetrojene ea tšepe e bohlooho e qhibilihisitsoeng e phahame ho feta tekanyo ea tekano, ho bonolo ho hlahisa li-pores tse kang crack-like nitrogen, 'me ductile iron e qhibilihisoa e atisa ho honyela likarolong tse teteaneng,' me litaba tsa litšila hodimo.Eketsa tloaelo ea ho lahla slag ho kenyelletsa;

3. Ho ea ka boholo bo fapaneng ba sebōpi, ho khetha boholo bo loketseng ba likaroloana tsa recarburizer ho ka ntlafatsa ka katleho lebelo la ho monya le sekhahla sa carburant ka tšepe e qhibilihisitsoeng.
