Lintlha:
Refractoriness ea litene tsa letsopa e tlaase 'me ha e tšoanelehe bakeng sa libaka tse phahameng tsa mocheso.
Ela hloko bopaki ba mongobo ho qoba tahlehelo ea matla ka mor'a ho kenngoa ha metsi.
Setene sa Magnesium
Likarolo: refractoriness e phahameng le khanyetso e matla ea khoholeho ea alkaline.
Kopo: e sebelisoa ka tlase le sebōping sa ontong ea coke le likarolo tse ling tse kopanang le lintho tsa alkaline.
Lintlha:
Litene tsa Magnesium li bonolo ho monya metsi 'me li hloka ho bolokoa hantle ho qoba mongobo.
Mocheso oa katoloso ea litene tsa magnesium o moholo, 'me tlhokomelo e lokela ho lefshoa mathateng a mocheso oa mocheso.
Litene tsa silicon carbide
Likarolo: conductivity e phahameng ea mocheso, ho hanyetsa ho roala, le ho hanyetsa mocheso o motle haholo.
Kopo: e sebelisoang monyako oa sebōpi, sekoahelo sa sebōpi, secheso le likarolo tse ling tsa ontong ea coke tse hlokang ho senya mocheso ka potlako.
Lintlha:
Litene tsa silicon carbide li theko e boima 'me li hloka ho khethoa ka mokhoa o utloahalang.
Qoba ho kopana le likhase tse matla tsa oxidizing ho thibela oxidation.
Refractory castables
Likarolo: kaho e bonolo, bots'epehi bo botle, le khanyetso e ntle ea mocheso oa mocheso.
Kopo: E sebelisetsoa ho lokisa ontong ea coke, likarolo tse rarahaneng tsa sebopeho le ho etsa lintho tse hlokahalang.
Lintlha:
Palo ea metsi e ekelitsoeng nakong ea kaho e tlameha ho laoloa ka thata ho qoba ho ama matla.
Mocheso o tlameha ho phahama butle nakong ea ho baka ho thibela ho peperana.
Refractory fiber
Likarolo: boima bo bobebe, insulation e ntle ea mocheso, le ho hanyetsa mocheso o matla haholo.
Kopo: E sebelisoa bakeng sa lera la ho kenya letsoho la lionto tsa coke ho fokotsa tahlehelo ea mocheso.
Lintlha:
Li-fibers tsa refractory ha li hanyetsane le tšusumetso ea mochine 'me li hloka ho qojoa ho senya ka ntle.
Shrinkage e ka 'na ea hlaha tlas'a mocheso o phahameng oa nako e telele' me e hloka tlhahlobo ea kamehla.
Litene tsa Corundum
Likarolo: refractoriness e phahameng haholo (kaholimo ho 1800 ° C) le khanyetso e matla ea kutu.
Kopo: E sebelisoa libakeng tse nang le mocheso o phahameng le libaka tse nang le khoholeho e phahameng ea lionto tsa coke, joalo ka libaka tse haufi le li-burners.
Mehato ya tlhokomelo:
Litene tsa Corundum li theko e boima 'me li hloka ho khethoa ka mokhoa o utloahalang.
Ela hloko ho kopana ha litene tsa litene nakong ea kaho.
2. Litlhokomelo bakeng sa tšebeliso ea thepa ea refractory ea ontong ea coke
Khetho ea lintho tse bonahalang
Khetha lisebelisoa tsa refractory ka mokhoa o utloahalang ho latela mocheso oa likarolo tse fapaneng tsa ontong ea coke, mecha ea litaba e senyang (acidic kapa alkaline) le mojaro oa mochini.
Qoba ho sebelisa lisebelisoa tsa refractory tsa mocheso o tlase libakeng tse nang le mocheso o phahameng ho thibela ho hlōleha ha thepa.
Boleng ba kaho
Laola ka thata boholo ba manonyeletso a litene 'me u sebelise seretse se nepahetseng sa refractory ho netefatsa hore ho na le masonry.
Bakeng sa li-castable tse refractory, kaho e tlameha ho etsoa ho ea ka karo-karolelano ho qoba ho eketsa metsi a mangata a amang matla.
Ts'ebetso ea ho baka ka ontong
Lionto tsa coke tse sa tsoa hahoa kapa tse lokisoang li hloka ho apewa. Mocheso o lokela ho phahamisoa butle nakong ea ho baka ho qoba ho petsoha kapa ho ebola ha thepa ea refractory ka lebaka la liphetoho tsa tšohanyetso tsa mocheso.
Tlhokomelo ea letsatsi le letsatsi
Kamehla hlahloba ho khathala, khoholeho le ho phatloha ha lisebelisoa tsa ho thibela mollo oa coke 'me u li lokise ka nako.
Qoba ts'ebetso e feteletseng ea mocheso oa lionto tsa coke ho thibela tšenyo e tlang pele ho nako ea thepa ea refractory.
Ho boloka le ho boloka
Lisebelisoa tsa refractory li lokela ho bolokoa sebakeng se omeletseng ho qoba mongobo (haholo-holo litene tsa magnesia le li-castable tse refractory).
Thepa ea refractory ea lisebelisoa tse fapaneng e lokela ho bolokoa ka thoko ho thibela pherekano.
Kakaretso
Lisebelisoa tse sebelisoang hangata ka liontong tsa coke li kenyelletsa litene tsa silika, litene tse phahameng tsa alumina, litene tsa letsopa, litene tsa magnesia, litene tsa silicon carbide, li-refractory castables, likhoele tse refractory le litene tsa corundum. Ha u sebelisa, lisebelisoa li lokela ho khethoa ho ea ka maemo a khethehileng a ho sebetsa, 'me tlhokomelo e lokela ho lefshoa ho boleng ba kaho, ts'ebetso ea ontong le tlhokomelo ea letsatsi le letsatsi ho lelefatsa bophelo ba tšebeletso ea ontong ea coke.
