Magnesia Carbon Brick bakeng sa Ladle

Lisebelisoa tsa refractory tse sebelisoang moleng oa slag oa ladle ea pele li ne li kopantsoe ka ho toba le litene tsa magnesia-chrome, ho qhibiliha ha motlakase ebe li kopantsoe le litene tsa magnesia-chrome le litene tse ling tsa boleng bo phahameng ba alkaline. Ka mor'a hore litene tsa MgO-C li sebelisoe ka katleho ho li-converter, litene tsa MgO-C li ne li boetse li sebelisoa molaong oa slag oa ladle ea ho hloekisa, 'me liphello tse ntle li ile tsa finyelloa. naha ea heso le Japane ka kakaretso li sebelisa litene tsa MgO-C tse nang le resin-bonded tse nang le carbon content ea 12% ho 20%, ha Europe e sebelisa litene tsa MgO-C tse nang le asphalt, tse nang le carbon content e ka bang 10%.

Kokura Steel Works of Sumitomo Metal Corporation e Japane e sebelisitse litene tsa MgO-C tse nang le MgO content ea 83% le C content ea 14-17% ho nkela litene tsa magnesia-chrome tse tlamahaneng ka kotloloho moleng oa slag oa VAD, le bophelo ba ts'ebeletso ea slag. mohala o ile oa eketseha ho tloha ho makhetlo a 20 ho isa ho makhetlo a 30-32 [9]. LF refining ladle ea Sendai Steel Plant Japane e sebelisitse litene tsa MgO-C ho nkela litene tsa magnesia-chrome sebaka, 'me bophelo ba tšebeletso ea mohala oa slag bo ile ba eketseha ho tloha ka makhetlo a 20-25 ho ea ho makhetlo a 40, ho finyella liphello tse ntle. Osaka Ceramics Refractory Co., Ltd. e ithutile liphello tsa carbon content le mofuta oa antioxidant ho hanyetsa oxidation, ho hanyetsa slag le mocheso o phahameng oa matla a ho feto-fetoha ha litene tsa MgO-C. Phuputso e bontša hore litene tsa MgO-C tse entsoeng ka motsoako oa magnesia a kopantsoeng le magnesia a sintered, a nang le 15% ea phosphorus graphite le motsoako o monyenyane oa magnesium-aluminium alloy e le li-antioxidants, li na le phello e ntle ea tšebeliso. Ha e sebelisoa ka 100-ton LF ladle slag line, sekhahla sa tšenyo se fokotsehile ka 20-30% ha se bapisoa le litene tsa MgO-C tse nang le carbon content ea 18% 'me ha ho na antioxidant,' me karolelano ea khoholeho ea mobu ke 1.2-1.3 mm / sebōpi [1].

Kaha litene tse hloekisitsoeng tsa ladle slag line ea naha ea heso li amohetse litene tsa MgO-C ho e-na le litene tsa magnesia-chrome, phello e pharaletseng ea tšebeliso e totobetse. Baosteel Group Corporation's 300t ladle slag line e qalile ho sebelisa litene tsa MT-14A magnesia-carbon ka Phupu 1989, 'me bophelo ba mola oa slag bo ntse bo le ka holimo ho makhetlo a 100; the 150T electric furnace ladle slag line e sebelisa litene tse tlaase tsa carbon magnesia-carbon ho qhibilihisa tšepe ea mohala, e nang le mocheso oa mocheso oa 1600 ℃ ~ 1670 ℃, o fihletseng liphello tse hlakileng.

Khamphani ea rona e sebetsa ka ho khetheha tlhahisong ea litene tsa khabone ea magnesia, litene tsa khabone tsa aluminium-magnesia, litene tse se nang k'habone bakeng sa li-ladle tse hloekisitsoeng, litene tsa aluminium-silicon carbide carbon bakeng sa litanka tsa torpedo, le litene tse ncha tsa magnesia tse se nang carbon le li-refractories tse fapaneng tsa amorphous, joalo ka tokiso. le lisebelisoa tsa lithunya bakeng sa li-converter, libono tsa motlakase le lilae. Re boetse re fana ka lihlahisoa tse entsoeng ka ho sisinyeha, joalo ka litene tsa moea oa ladle, litene tsa setulo sa nozzle tse kenang moea, litene tsa setulo sa nozzle le lisebelisoa tse entsoeng esale pele. Re ntlafalitse ho ba khoebo e felletseng ea refractory e kopanyang lipatlisiso tsa thepa e tala, ts'ebetso e tebileng le khoebo. Laborator ea rona e na le lisebelisoa tse felletseng tsa liteko le tlhahlobo. Lisebelisoa tsa rona li ka etsa lisebelisoa tse tala, lihlahisoa tse felileng, tsa etsa liteko le ho hlahloba, le ho hlahisa lihlahisoa tse ncha. Re lumela hore saense le thekenoloji ke tataiso ea rona. Ka hona, re fumane theknoloji e tsoetseng pele lapeng le kantle ho naha, re ntse re ntlafatsa boleng ba sehlahisoa, litaba tsa mahlale le tsa theknoloji le botsitso ba tlhaho, ka hona, re ntlafatsa theknoloji ea tlhahiso le ho nchafatsa lisebelisoa tsa rona tsa tlhahiso khafetsa. Re fana ka mefuta e fapaneng ea lits'ebeletso tsa tekheniki ho latela boholo le litekanyetso tsa tekheniki tsa li-converter, libono tsa arc tsa motlakase le li-ladle ho latela litlhoko tsa bareki.
