Indastering ea ho etsa tšepe, ladle ea tšepe ke sejana sa bohlokoa se nkang, se tšoarang le ho tšoara tšepe e qhibilihisitsoeng pakeng tsa mekhoa e fapaneng ea tlhahiso. Ts'ebetso ea eona e ama ka kotloloho boleng ba tšepe, katleho ea tlhahiso, le litšenyehelo tsa ts'ebetso. Leha ho le joalo, tšepe e qhibilihisitsoeng e fihla mocheso o ka holimo ho 1,600 ° C kapa ho feta, 'me e boetse e sebelisana le li-slags tse mabifi, khoholeho ea mechine, le ho sisinyeha ha mocheso-e leng se bakang mathata a maholo ho lisebelisoa tse hanyetsang tse koahelang lesela la tšepe. Ke hona moolitene tsa khabone tsa magnesium(Litene tsa MgO-C) li iponahatsa e le tharollo ea mantlha, e fana ka nako e telele e ke keng ea lekanngoa le ho ts'epahala ha ts'ebetso ea ladle ea tšepe.
Hobaneng ha litene tsa Magnesium Carbon li le Bohlokoa bakeng sa Ladles tsa tšepe
Li-ladle tsa tšepe li hloka lisebelisoa tse hanyetsang tse ka mamellang maemo a feteletseng ntle le ho senya ts'ebetso. Hangata litene tsa khale tsa refractory li hlōleha ho finyella litlhoko tsena, tse lebisang ho nkeloa sebaka khafetsa, ho fokotseha ha tlhahiso, le litšenyehelo tse eketsehileng. Leha ho le joalo, litene tsa khabone ea Magnesium li kopanya matla a high-purity magnesia (MgO) le graphite ho sebetsana le phephetso e 'ngoe le e 'ngoe ea bohlokoa ea lesela la tšepe la tšepe:
1. Khanyetso e ikhethang ea Mocheso o Phahameng
Magnesia, e leng karolo ea mantlha ea litene tsa MgO-C, e na le sebaka se phahameng sa ho qhibiliha se ka bang 2,800 ° C - se fetang hōle mocheso o phahameng oa tšepe e qhibilihisitsoeng. Ha e kopantsoe le graphite (thepa e nang le botsitso bo botle ba mocheso), litene tsa carbon tsa magnesium li boloka botšepehi ba tsona ba sebopeho esita le tlas'a nako e telele ho 1,600 + ° C tšepe e qhibilihisitsoeng. Khanyetso ena e thibela ho nolofala ha litene, ho fetoha, kapa ho qhibiliha, ho netefatsa hore ladle ea tšepe e lula e bolokehile ebile e sebetsa ka nako e telele.
2. Superior Slag Corrosion Resistance
Tšepe e qhibilihisitsoeng e tsamaea le li-slags-byproducts tse nang le li-oxide tse ngata (tse kang SiO₂, Al₂O₃, le FeO) tse senyang haholo ho li-refractories. Magnesia ka litene tsa MgO-C e arabela hanyane ka li-slags tsena, e etsa lera le letenya, le sa keneng holim'a setene se thibelang ho kenella ha slag ho feta. Ho fapana le litene tsa alumina-silica, tse hoholehang habonolo ke asiti kapa li-slags tsa motheo, litene tsa khabone ea magnesium li boloka botenya ba tsona, li fokotsa kotsi ea ho lutla ha ladle.
3. E babatsehang Thermal Shock Resistance.
Lilae tsa tšepe li futhumatsoa khafetsa (ho tšoara tšepe e qhibilihisitsoeng) le ho pholile (nakong ea tlhokomelo kapa nakong ea ho se sebetse) -e leng mokhoa o bakang ho tšoha ha mocheso. Haeba lisebelisoa tsa refractory li ke ke tsa mamella liphetoho tse potlakileng tsa mocheso, li tla phunyeha, tse lebisang ho hlōleha pele ho nako. Graphite ka har'a litene tsa khabone ea magnesium e sebetsa joalo ka "buffer," e monyang khatello ea maikutlo le ho thibela ho hlaha ha crack. Sena se bolela hore litene tsa MgO-C li ka mamella lipotoloho tse makholo tsa ho futhumatsa-ho futhumatsa ntle le ho lahleheloa ke ts'ebetso, ho lelefatsa bophelo ba ts'ebeletso ea lesela la tšepe.
4. Litšenyehelo tse Fokotsoeng tsa Moaparo le Tlhokomelo
Ho roala ha mochini ho tsoa ho tšepe e qhibilihisitsoeng, motsamao oa ladle, le ho khephoha ha slag ke taba e 'ngoe e kholo bakeng sa li-refractories tsa tšepe. Litene tsa khabone ea Magnesium li na le matla a phahameng a mochini le ho thatafala, ka lebaka la maqhama lipakeng tsa lijo-thollo tsa magnesia le graphite. Ho tšoarella hona ho fokotsa ho roala ha litene, ho lumella ladle hore e sebetse nako e telele pakeng tsa li-relinings. Bakeng sa limela tsa tšepe, sena se fetolela nako e fokolang ea ho theoha, litšenyehelo tse tlaase tsa basebetsi bakeng sa ho fetola li-refractory, le linako tsa tlhahiso tse tsitsitseng haholoanyane.
Lisebelisoa tsa bohlokoa tsa Magnesium Carbon Bricks ka Steel Ladles
Litene tsa khabone ea Magnesium ha se tharollo ea boholo bo le bong-li etselitsoe likarolo tse fapaneng tsa ladle ea tšepe ho latela maemo a itseng a khatello ea maikutlo:
Ladle Bottom le Walls:Mabota a ka tlaase le a tlaase a ladle a kopane ka ho toba, nako e telele le tšepe e qhibilihisitsoeng le li-slags. Mona, litene tsa khabone tsa magnesium tse matla haholo (tse nang le 10-20% ea dikahare tsa graphite) li sebelisoa ho hanela ho bola le ho senyeha.
Ladle Slag Line:Mohala oa slag ke sebaka se tlokotsing ka ho fetisisa, kaha se tobane le ho pepeseha ho tsoelang pele ho li-slags tse senyang le mocheso oa mocheso. Litene tsa pele tsa magnesium carbon (tse nang le li-graphite tse phahameng le li-antioxidants tse kang Al kapa Si) li sebelisoa mona ho ntlafatsa bophelo ba tšebeletso.
Ladle Nozzle le Tap Hole:Libaka tsena li hloka litene tse nang le mocheso o phahameng oa mocheso le ho hanyetsa khoholeho ho netefatsa hore tšepe e qhibilihisitsoeng e phalla hantle. Ho sebelisoa litene tse khethehileng tsa MgO-C tse nang le magnesia a matle-grained ho thibela ho koala le ho lelefatsa bophelo ba nozzle.
Melemo ea Limela tsa Tšepe: Ho Feta ho Tšoareha
Ho khetha litene tsa khabone tsa magnesium bakeng sa lithako tsa tšepe tsa ladle ho fana ka melemo ea khoebo e bonahalang bakeng sa baetsi ba tšepe:
Boleng bo Ntlafetseng ba Litšepe:Ka ho thibela khoholeho ea mobu, litene tsa MgO-C li fokotsa kotsi ea likaroloana tse hanyetsang tse silafatsang tšepe e qhibilihisitsoeng-ho netefatsa hore ho na le lik'hemik'hale tse tsitsitseng le liphoso tse fokolang lihlahisoa tsa tšepe tse felileng.
Ho Boloka Matla:Mocheso o phahameng oa mocheso oa graphite ka litene tsa MgO-C o thusa ho boloka mocheso ka ladle, ho fokotsa tlhokahalo ea ho futhumatsa tšepe e qhibilihisitsoeng. Sena se fokotsa tšebeliso ea mafura le khabone
Bophelo bo Botle ba Tšebeletso ea Ladle: Ka karolelano, litene tsa litene tsa magnesium tsa carbon li nka nako e telele ka makhetlo a 2-3 ho feta litlolo tse tloaelehileng tsa refractory. Bakeng sa ladle e tloaelehileng ea tšepe, sena se bolela ho reline hang feela likhoeling tse ling le tse ling tse 6-12, ha ho bapisoa le makhetlo a 2-3 ka selemo le lisebelisoa tse ling.
Khetha litene tsa Khabone tsa Magnesium tsa boleng bo holimo bakeng sa litepisi tsa hau tsa tšepe
Ha se litene tsohle tsa magnesium carbon tse entsoeng ka ho lekana. Ho eketsa ts'ebetso, batla lihlahisoa tse nang le:
Magnesia a hloekileng (95%+ MgO content) ho netefatsa hore ho na le khanyetso ea kutu
graphite ea boleng bo holimo (litekanyetso tse tlase tsa molora) bakeng sa ho hanyetsa mocheso o matla oa mocheso
Lisebelisoa tse tsoetseng pele tsa bonding le li-antioxidants ho matlafatsa matla a litene le ho thibela oxidation ea graphite
At Shandong Robert Refractory, Re sebetsa ka ho khetheha ho etsa litene tsa khabone tsa magnesium tsa premium tse etselitsoeng lisebelisoa tsa tšepe tsa ladle. Lihlahisoa tsa rona li tlas'a taolo e tiileng ea boleng-ho tloha ho khetho ea thepa e tala ho ea tekong ea ho qetela-ho netefatsa hore li finyella litekanyetso tse thata ka ho fetisisa tsa ho etsa tšepe. Hore na o sebelisa leloala le lenyenyane la tšepe kapa polante e kholo e kopaneng, re ka fana ka litharollo tse ikhethileng ho fokotsa litšenyehelo le ho eketsa tlhahiso.
Ikopanye le Rona Kajeno
U itokiselitse ho ntlafatsa li-refractories tsa hau tsa tšepe ka litene tsa khabone ea magnesium? Ikopanye le sehlopha sa rona sa litsebi tsa refractory ho buisana ka litlhoko tsa hau, ho fumana quote ea motho ka mong, kapa ho ithuta haholoanyane ka litene tsa MgO-C li ka fetolang ts'ebetso ea hau ea ho etsa litšepe.
