Mokhoa oa ho Fokotsa Li-inclusions tsa oxide In Bearing Steel

Ho kenyelletsoa ka tšepe ke e 'ngoe ea lintlha tsa mantlha tse amang mokhathala bophelo ba ho ts'oara tšepe. Senotlolo sa ho laola inclusions ka tšepe ke ho laola likarolo tsa oksijene le li-oxide ka tšepe. Mehopolo ea mantlha ea ho fokotsa inclusions ea tšepe ka tšepe e latelang.

1, Taolo ea dikahare k'habone ka phaphatha qetellong ea sebōpi mathomo hloekisa

Ha khabone e qetellong e le tlase haholo, oksijene e qhibilihisitsoeng ka tšepe e phahame, e lebisang ts'ebelisong ea aluminium e ngata nakong ea deoxidation e latelang, mme kakaretso ea inclusions e tla eketseha, e tlisang mathata ho ho hloekisoa hamorao; Ntle le moo, oxidizability ea slag e tla eketseha ka ho hlaka, ka hona ho thata ho fetola le ho laola sebopeho sa slag ha ho hloekisoa hamorao. Empa likarolo tse phahameng haholo tsa khabone ha u tlanya qetellong li tla tlisa khatello ea ts'ebetso ea taolo ea sebopi sa mantlha sa ho hloekisa. Ho qhibilihisa EAF, likarolo tsa kh'abone tsa ntlha-kholo li laoloa ka kakaretso ho 0.2%.

2, Selection ea deoxidizer loketseng

Ts'ebetsong ea tlhahiso ea tšepe, lihlahisoa tsa oksijene tse ka hara tšepe li ka fokotsoa mme palo e nepahetseng ea asiti e qhibilihang ka asiti e ka fumanoa ka deoxidation ea hoqetela ka aluminium. Ha lihlahisoa tsa aluminium e qhibilihang ka asiti li le holimo haholo, tšireletso ea tšepe e qhibilihisitsoeng ha e ntle, e leng bonolo ho e lebisa ho oxidation ea bobeli, ka hona e eketsa litaba tsa inclusions tsa brittle Al2O3; Ha lihlahisoa tsa aluminium e qhibilihang ka asiti li le tlase, ho kenella ha silicon ea bobeli le ho fokotseha ha mocheso oa tšepe e qhibilihisitsoeng ho lebisa ho pula ea oksijene e qhibilihisitsoeng, e lebisang ho thehoeng ha li-coarse silicate inclusions tse ruileng SiO2. Ho ea ka lipatlisiso, ha likahare tsa aluminium e qhibilihang ka har'a tšepe li laoloa ho 0.02% ~ 0.04%, boholo ba tšepe bo ka ntlafatsoa, ​​e le ho fumana matla a phahameng le ho thatafala.

Barium ke sehlophisi se loketseng sa deoxidizing. Motsoako oa Barium ha o na matla a ho theola 'mele feela, empa hape o ka hlahisa likarolo tse setseng tsa tšepe. Ho ea ka lipatlisiso, kamora ho tlosa tšepe e nang le "Al Al" alloy, kakaretso ea oksijene e ka har'a tšepe e theohela ka potlako ho boleng bo tsitsitseng. Kamora nako, ha ho na barium e nang le li-spheroidal inclusions ka hara tšepe, 'me masalla a siling a tšepe hantle. Li-inclusions li hantle, li qhalakantsoe ebile li arolelitsoe ka mokhoa o ts'oanang.

Magnesium e na le phello e kholo ho phetolo ea inclusions tsa Al2O3 tsa ho jara tšepe. Ho latela lipatlisiso, ha lihlahisoa tsa aluminium e qhibilihang ka asiti e le 0.03%, ho na le 210-4% magnesium ka tšepe, ke ho re, ho kenyeletsoa Al 2O 3 ho ka fetoloa ho MgO · Al 2O 3, le Likahare tsa Mg ka tšepe li feta 10% μ Liphetho li bonts'a hore li-inclusions tsa Al 2O 3 tse nang le m li fetotsoe hore e be tse ntle le tse chitja mg Al spinel inclusions, tseo ka tlase ho 5 μ 46%, tse ling li 5 ~ 10 μ M.

3, Optimization ea ho hloekisa slag sebopeho

Ho fumanoa hore ha boleng ba binary ea ho hloekisa slag bo eketseha ho tloha ho 2.0 ho isa ho 4.5, kakaretso ea oksijene qetellong ea tšepe e qhibilihisitsoeng e fokotseha ho tloha ho 20 10-6 ho isa ho 11 10-6, mme palo yohle le sebaka sa inclusions lia fokotseha. Li-inclusions tse tloaelehileng tsa tšepe e qhibilihisitsoeng e hloekisitsoeng ke slag e phahameng li brittle inclusions tse kang Al2O3 le Al Mg spinel, eo boholo ba eona bo ka tlase ho 5 μ m. Ho eketsa litaba tsa Al2O3 kapa ho eketsa CaF2 le ho fokotsa litaba tsa MgO ho ka ntlafatsa haholo lebelo le bokhoni ba ho hloekisa slag ho inclusions inclusions.

4, godisiwa ya thulaganyou e qhibilihisa

E le ho fumana tšepe ea boleng bo holimo, ho eketsa tšepe e qhibilihisitsoeng le ho khetha litšila tsa boleng bo holimo bakeng sa ho qhibilihisa ke mekhoa e sebelisoang haholo. Ts'ebetsong ea metallurge ea ladle, ho laola ka nepo litaba tsa Al, Si kapa Ca ka tšepe ho ts'ehetsa deoxidation le desulfurization, ho sebelisoa ho betla ka mokhoa o sireletsang ts'ebetsong eohle, litaba tse kenyelletsoang li tla fokotsoa haholo. Ho qhibiliha ha vacuum ke tsela ea bohlokoa ea ho fokotsa likahare tsa inclusions. Ka lephaka phahameng, dikahare oksijene ka tšepe ka fokotswa ho tlase 10-6. Ho hloekisoa ha Electroslag ho ka fumana phello e ntle ea ho qhibilihisa ho feta ho qhibilihisa moea. Ho hloekisa Electroslag ha ho fokolise feela oksijene ea tšepe, empa hape ho fokotsa boholo ba inclusions ka tšepe, e le hore kabo ea inclusions e tšoane haholoanyane. Kamora ho hlakola, e fana ka menyetla ea li-inclusions tse kholo ho phaphamala.

Hajoale, ho kenella ka vacuum le ho qhibiliha ho sa sebelisoeng ho sebelisoa haholo ho jara tšepe bakeng sa merero ea bohlokoa lapeng le kantle ho naha. Bohloeki ba tšepe e sa hloekang e sa hloekang 6Cr14Mo e hlahisitsoeng ke ts'ebetso ena e ntlafalitsoe haholo, dikahare tsa oksijene ke 510-4 feela, mme inclusions ea oxide e tlase ka bongata, e nyane ka boholo ebile e ajoa ka mokhoa o ts'oanang.
