Ho na le mefuta e mengata ea thepa e hanyetsang e sebelisoang liontong tsa coke, 'me thepa ka' ngoe e na le maemo a eona a itseng a ts'ebeliso le litlhoko tsa ts'ebetso. Tse latelang ke thepa e hanyetsang e sebelisoang hangata liontong tsa coke le mehato ea tsona ea ho itšireletsa:
1. Lisebelisoa tse sebelisoang hangata tse hanyetsang liontong tsa coke
Litene tsa silicon
Likarolo: ho hanyetsa mocheso o phahameng (kaholimo ho 1650℃), ho hanyetsa ho bola ha asiti, le botsitso bo botle ba mocheso.
Tšebeliso: E sebelisoa haholo-holo libakeng tse nang le mocheso o phahameng joalo ka kamore ea ho tuka, kamore ea ho baka khabone, le karolo e ka holimo ea onto ea coke.
Mehato ya tlhokomelo:
Litene tsa silicon li sekametse phetohong ea kristale ka tlase ho 600℃, e leng se fellang ka liphetoho tsa bophahamo, kahoo li lokela ho qojoa libakeng tse nang le mocheso o tlase.
Nakong ea kaho, li-connection tsa litene li tlameha ho laoloa ka thata ho thibela katoloso ea li-connection tsa litene mochesong o phahameng.
Litene tsa alumina tse phahameng
Likarolo: ho hanyetsa mocheso haholo (kaholimo ho 1750℃), ho hanyetsa mocheso hantle, le ho hanyetsa mafome ka matla.
Tšebeliso: E sebelisoa leboteng la sebōpi, tlase ea sebōpi, kamoreng ea polokelo ea mocheso le likarolong tse ling tsa onto ea coke.
Mehato ya tlhokomelo:
Litene tsa alumina tse nang le alumina e ngata li na le khanyetso e fokolang khahlanong le mafome a alkaline 'me li hloka ho qoba ho kopana ka ho toba le lintho tse nang le alkaline.
Nakong ea kaho, tlhokomelo e lokela ho lefshoa ho omeletseng le ho besoa ha 'mele oa setene ho thibela ho petsoha.
Setene sa letsopa la mollo
Likarolo: ho hanyetsa mocheso hantle, theko e tlase, ho hanyetsa mocheso hantle.
Tšebeliso: e sebelisoa libakeng tse nang le mocheso o tlase joalo ka mokelikeli oa onto ea coke le karolo e ka tlase ea kamore ea polokelo ea mocheso.
Lintlha:
Ho se kgone ho hanela ditene tsa letsopa ho tlase mme ha ho a lokela dibakeng tse nang le mocheso o phahameng.
Ela hloko mongobo ho qoba tahlehelo ea matla ka mor'a ho monngoa ha metsi.
Setene sa magnesium
Likarolo: ho hanyetsa haholo le ho hanyetsa khoholeho ea alkaline ka matla.
Tšebeliso: e sebelisoa ka tlase le ka ontong ea onto ea coke le likarolo tse ling tse kopanang le lintho tse nang le alkaline.
Lintlha:
Litene tsa magnesium li monya metsi habonolo 'me li hloka ho bolokoa hantle ho qoba mongobo.
Tekanyo ea katoloso ea mocheso ea litene tsa magnesium e kholo, 'me tlhokomelo e lokela ho lefshoa mathateng a ho phatloha ha mocheso.
Litene tsa silicon carbide
Likarolo: ho khanna mocheso o phahameng, ho hanyetsa ho tsofala, le ho hanyetsa ho tsofala ha mocheso hantle.
Tšebeliso: e sebelisoa monyako oa sebōpi, sekoahelo sa sebōpi, secheso le likarolo tse ling tsa onto ea coke tse hlokang ho felisoa ha mocheso ka potlako.
Lintlha:
Litene tsa silicon carbide li theko e boima 'me li hloka ho khethoa ka tsela e utloahalang.
Qoba ho kopana le likhase tse matla tse eketsang oksideishene ho thibela oksideishene.
Li-castle tse hanelang ho phatloha
Likarolo: kaho e bonolo, botšepehi bo botle, le ho hanyetsa ho ts'oaroa ke mocheso hantle.
Tšebeliso: E sebelisoa bakeng sa ho lokisa onto ea coke, likarolo tse rarahaneng tsa sebopeho le ho lahla lintho ka botlalo.
Lintlha:
Bongata ba metsi a eketsoang nakong ea kaho bo lokela ho laoloa ka thata ho qoba ho ama matla.
Mocheso o lokela ho nyoloha butle nakong ea ho baka ho thibela ho petsoha.
Faeba e halefisang
Likarolo: boima bo bobebe, ho thibela mocheso hantle, le ho hanyetsa mocheso hantle.
Tšebeliso: E sebelisoa bakeng sa lera la ho thibela mocheso la lionto tsa coke ho fokotsa tahlehelo ea mocheso.
Lintlha:
Likhoele tse halefisang ha li hanele tšusumetso ea mechine 'me li hloka ho qojoa tšenyo ea kantle.
Ho fokotseha ho ka etsahala tlas'a mocheso o phahameng oa nako e telele 'me ho hloka tlhahlobo ea kamehla.
Litene tsa Corundum
Likarolo: ho hanyetsa mocheso ho hoholo haholo (ho feta 1800°C) le ho hanyetsa ho matla ha mafome.
Tšebeliso: E sebelisoa libakeng tse nang le mocheso o phahameng le tse nang le khoholeho e phahameng ea lionto tsa coke, joalo ka haufi le li-burners.
Mehato ya tlhokomelo:
Litene tsa Corundum li bitsa chelete e ngata 'me li hloka ho khethoa ka tsela e utloahalang.
Ela hloko ho teteana ha litene nakong ea kaho.
2. Litlhokomelo tsa tšebeliso ea lisebelisoa tse hanyetsang ontong ea coke
Khetho ea thepa
Khetha thepa e hanyetsang mocheso ka ho loketseng ho latela mocheso oa likarolo tse fapaneng tsa onto ea coke, mecha ea phatlalatso e senyang (e nang le asiti kapa alkaline) le mojaro oa mechini.
Qoba ho sebelisa thepa e hanelang mocheso o tlase libakeng tse nang le mocheso o phahameng ho thibela ho senyeha ha thepa.
Boleng ba kaho
Laola boholo ba litene ka tieo 'me u sebelise seretse se nepahetseng se hanyetsang ho netefatsa hore majoe a majoe a teteaneng a teteaneng.
Bakeng sa di-castable tse hanelang, kaho e tlameha ho etswa ho ya ka karolelano ho qoba ho eketsa metsi ho feteletseng ho amang matla.
Mosebetsi oa ho baka ka ontong
Lionto tsa coke tse sa tsoa hahoa kapa tse lokisitsoeng li hloka ho besoa. Mocheso o lokela ho phahamisoa butle nakong ea ho baka ho qoba ho petsoha kapa ho taboha ha lintho tse hanyetsang ka lebaka la liphetoho tsa mocheso tse sa lebelloang.
Tlhokomelo ea letsatsi le letsatsi
Kamehla hlahloba ho tsofala, ho khoholeha le ho petsoha ha thepa e hanelang ontong ea coke 'me u li lokise ka nako.
Qoba ho sebetsa ka mocheso o feteletseng ha lionto tsa coke ho thibela tšenyo e sa lebelloang linthong tse hanyetsang.
Polokelo le paballo
Disebediswa tse halefisang di lokela ho bolokwa tikolohong e omileng ho qoba mongobo (haholoholo ditene tsa magnesia le di-castable tse halefisang).
Disebediswa tse halefisang tsa thepa e fapaneng di lokela ho bolokwa ka thoko ho thibela pherekano.
Kakaretso
Lisebelisoa tse atisang ho sebelisoa tse hanelang liontong tsa coke li kenyelletsa litene tsa silica, litene tse phahameng tsa alumina, litene tsa letsopa, litene tsa magnesia, litene tsa silicon carbide, li-castable tse hanelang, likhoele tse hanelang le litene tsa corundum. Ha li sebelisoa, thepa e lokela ho khethoa ho latela maemo a itseng a mosebetsi, 'me tlhokomelo e lokela ho lefshoa boleng ba kaho, ts'ebetso ea onto le tlhokomelo ea letsatsi le letsatsi ho atolosa bophelo ba tšebeletso ea onto ea coke.
