Ts'ebetso ea tlhahiso ea Recarburizer le lisebelisoa tse tala
Recarburizer ke ntho e nang le carbonaceous.Li-carbuzer li eketsoa nakong ea ts'ebetso ea ho qhibilihisa ho tlatselletsa khabone e lahlehileng nakong ea ho qhibiliha ha tšepe.Rea tseba hore ho na le mefuta e mengata ea li-recarburizers, tse kang petroleum coke recarburizers, maiketsetso a graphite recarburizers, joalo-joalo, kahoo lisebelisoa tse tala tse hlokahalang bakeng sa li-recarburizer le tsona li fapane, joale lisebelisoa tse tala tsa li-recarburizer ke life?Mokhoa oa ho recarburizer ke eng?Xiaobian o tla u joetsa ka lisebelisoa le lits'ebetso tse hlokahalang bakeng sa recarburizer.
Lisebelisoa tse tala tse hlokahalang bakeng sa li-recarburizers
Ho na le mefuta e mengata ea lisebelisoa tse tala bakeng sa li-recarburizers, ho kenyelletsa mashala, khabone e thehiloeng ka mashala, coke, graphite, coke e tala ea petroleum, joalo-joalo, eo ho nang le mekhahlelo e mengata e menyenyane le likarolo tse fapaneng.
Hajoale, boholo ba li-recarburizer tse 'marakeng, ho kenyeletsoa li-electrode tsa graphite, coke ea petroleum ea graphitized, joalo-joalo, li sebelisa coke e tala ea peterole.Coke ea petroleum e tala e fumanoa ka ho tšela oli e setseng le petroleum pitch e fumanoang ka ho tšeloa ha oli e tala tlas'a khatello ea sepakapaka kapa vacuum.Coke e tala ea petroleum e na le lintho tse ngata tse sa hloekang 'me e ke ke ea sebelisoa ka ho toba e le recarburizer.E tlameha ho ba calcined kapa graphitized.Li-recarburizer tsa boleng bo holimo hangata li hloka graphitization.Tlas'a maemo a phahameng a mocheso, tlhophiso ea liathomo tsa carbon e ka sebōpeho sa microscopic ea graphite, kahoo e bitsoa graphitization.Graphitization e ka fokotsa litaba tsa litšila ka har'a recarburizer, ea eketsa khabone ea "recarburizer", 'me ea fokotsa sebabole.Li-recarburizer li sebelisoa bakeng sa ho lahla, tse ka eketsang haholo palo ea litšepe, tsa fokotsa palo ea tšepe ea kolobe kapa tsa boloka tšepe ea kolobe.
Mokhoa oa Carburizer
Ka lebaka la mefuta e fapaneng ea lisebelisoa tse tala bakeng sa li-recarburizers, lits'ebetso le tsona li fapane, empa ho na le tse tharo tse latelang:
1. Calcination
Lisebelisoa tse tala tsa carbonaceous li calcined ka mocheso o phahameng oa 1200-1500 ° C ha ho se na moea.Calcination e baka letoto la liphetoho sebopeho le thepa ea physicochemical ea lisebelisoa tse fapaneng tse tala.Ke mokhoa oa ho phekola mocheso oa recarburizer.Ka bobeli anthracite le petroleum coke li na le palo e itseng ea lintho tse feto-fetohang 'me li hloka ho calcination.Leha ho le joalo, ha petroleum coke le pitch coke li tsoakoa ’me li sebelisoa pele ho calcination, li lokela ho romeloa ho calciner bakeng sa ho kaloa hammoho le petroleum coke.
2. Ho besoa
Ho besoa ke mokhoa oa ho phekola mocheso oo ho oona lijo tse tala tse hatelitsoeng li futhumatsoang ka tekanyo e itseng ea ho futhumatsa ka mokhoa o sireletsang sebōping sa ho futhumatsa tlas'a boemo ba ho arola moea.
Sepheo sa ho halika ke ho felisa li-volatiles.Ka kakaretso, mefuta e ka bang 10 ea li-volatiles e lokolloa ka mor'a ho halika.Ka hona, lihlahisoa tse halikiloeng ka kakaretso ke 90;sekontiri se phehiloe, 'me sehlahisoa se halikiloe ho ea ka maemo a itseng a ts'ebetso, e le hore sekontiri se phehiloe,' me ho thehoa marang-rang a coke pakeng tsa likaroloana tse tala, tse kopanyang ka tieo lisebelisoa tsohle tse tala tse nang le boholo bo fapaneng ba likaroloana hammoho.Etsa hore lihlahisoa tsa # # li be le thepa e itseng ea 'mele le ea lik'hemik'hale.Tlas'a maemo a tšoanang, ho phahama ha lebelo la ho pheha, ho ntlafatsa boleng;tabeng ea geometry e tsitsitseng, sehlahisoa se tla nolofatsa 'me se tlamang se tla falla nakong ea ho baka.Ha mocheso o ntse o eketseha, ho thehoa marang-rang a coking, a thatafatsang sehlahisoa.Ka hona, sebopeho sa eona ha se fetohe ha mocheso o ntse o eketseha.
3. Extrusion
Sepheo sa ts'ebetso ea extrusion ke ho etsa hore thepa e tala e fete ka har'a hlobo ea sebopeho se itseng tlas'a khatello, 'me e be billet e nang le sebōpeho se itseng le boholo ka mor'a hore e kopane le ho holofala ka polasetiki.The extrusion molding process is especially the plastic deformation process of the peista.Ts'ebetso ea extrusion e etsahala ka kamoreng ea lintho tse bonahalang le nozzle e kobehileng.Thepa e chesang ka kamoreng e sutumetsoa ke plunger e ka morao.Ho qobelloa ho tlosoa ha khase ho tloha linthong tse tala, ho kopana ho tsoelang pele ha thepa e tala, le ho tsamaea ka nako e le 'ngoe ha thepa e tala ho ea pele.Ha thepa e tala e tsamaea karolong ea cylindrical ea kamore ea thepa, thepa e tala e ka nkoa e le phallo e tsitsitseng, 'me karolo e' ngoe le e 'ngoe ea likaroloana e tsamaea ka tsela e tšoanang.Ha thepa e tala e kena ka har'a nozzle ea extrusion 'me e na le deformation e nang le sebopeho sa arc, thepa e tala e haufi le lebota la nozzle e tla ba le khanyetso e kholo ea likhohlano ha e ntse e tsoela pele,' me lera la thepa le qala ho kobeha.Thepa e tala e na le lebelo le fapaneng la tsoelo-pele, le tsoelo-pele ea ka hare ea thepa e tala.Ka hona, boima ba sehlahisoa ho latela tataiso ea radial ha bo tšoane, kahoo bo hlahisa khatello ea kelello e ka hare e bakoang ke litekanyetso tse fapaneng tsa phallo ea likarolo tse ka hare le tse ka ntle ka har'a block e extruded.Ka mor'a hore peista e kene karolong e otlolohileng ea deformation, e ntšoa 'me e thehoa.
Mokhoa oa extrusion o hloka ho kenyelletsa setlamo se sengata haholo bakeng sa ho bopa, mme litaba tsa khabone ka kakaretso ha li fihlelle litlhoko tsa li-recarburizer tsa boleng bo holimo.Phofo ea graphite e hatelitsoeng, hobane ke block e tiileng, ha e na sebopeho sa porous, kahoo lebelo la ho monya le sekhahla sa ho monya ha se hantle joalo ka li-calcined le calcined recarburizers.
